Chapter 10

Battle’s End

ON TO KUNISHI RIDGE

At the same time the 6^th Marine Division was landing on Oroku Peninsula, the 1^st Marine Division was rolling up gains totaling 1,800 yards in its drive south from the Naha-Yonabaru valley.    General del Valle’s Regiments made this advance while a faltering Division Supply System behind them threatened to break down completely because of the mud and the rain.    The roads had become such quagmires that even tractors and bulldozers became stalled when they attempted to drag Division vehicles out of or over the mud.    Tanks and trucks were unable to cross the Kokuba; the approaches to the bridge at the mouth of the river were untrafficable for a distance of over 500 yards.    In an effort to facilitate resupply and evacuation operations, tanks were ordered off the roads.    In general, forward units were Logistically Supported by Marines who hand carried supplies up to dumps behind the lines; the “trails were only negotiable for foot troops—vehicles could not have been used if we [2/7] could have gotten them across the inlet.”

On the Division right on 4 June, the 7^th Marines pushed forward to close off the neck of Oroku Peninsula and further entrap Japanese forces there.    The hill mass at the base of Oroku in the Division Zone held the commanding terrain feature of the area, Hill 108.    This height overlooked the East China Sea and the next major Division Objective, Itoman.    Although the exposed right flank of the 7^th Marines came under constant harassing fire from high ground to the right of the Division Boundary, the Division left flank was generally secure since the adjacent 96^th Infantry Division had moved forward steadily since its advance from the Kokuba River line.

After the Japanese defenses at Shuri had collapsed, the 1^st Marines remained behind in the vicinity of the city to patrol and mop up, and the 5^th Marines pursued the fleeing enemy.    Before the dawn of 4 June, the 1^st joined in the pursuit; 3/1 made a wide swing through the Zone of the 96^th Division in order to take the high ground north of Iwa and Shindawaku while 1/1 passed through the lines of the 5^th Marines and took up positions in front of Hills 57 and 107.

By 0930, 3/1 had reached the small village of Tera, just north of Chan.     At 1300, the Battalion point was pinned down by fire coming from high ground just west of the Tomusu-Iwa road, and the advance guard attempted without success to clean out the enemy position.    Just before 1400, the time scheduled for 3/1 to make its coordinated attack with 1/1, a cloudburst occurred.    The supply problems here were further aggravated by the rain, and because of a communications blackout between the Battalion and its Artillery and Naval Gunfire Support, 3/1 broke contact with the enemy and withdrew to a bivouac area in a draw behind the 383d Infantry.

At 1730, Lieutenant Colonel Ross’ entire Battalion was in defilade, protected from enemy artillery fire.     Contact with the Artillery Battalions and Naval Gunfire Support ships was still lacking at this time and a mortar ammunition shortage existed.     The afternoon downpours had turned the roads into morasses and the fields into calf-deep mud wallows in which the suction of the ooze pulled the soles off of the shoes of men walking in it.

Since food as well as mortar ammunition was in short supply, the 383d Infantry generously supplied the Battalion with enough K-rations to enable 3/1 to issue two meals to each Marine.    It was the general consensus of the members of 3/1 that “taking all things into consideration, this day probably was the most miserable spent on Okinawa by the men of this Battalion.”    In addition, 3/1 found itself all but isolated from its Regiment, since there was neither communication with nor a supply route to the 1^st Marines CP, some 11,000 yards to the rear.

The 1^st Battalion, 1^st Marines, passed through the lines of 2/5 at approximately 1000 on the 4^th.     This was nearly three hours after Company F of 2/5 had attacked and seized Hill 107 without opposition, and completed its occupation of the high ground across the entire front of the Regiment.    When 1/1 took over from 2/5 at noon, the latter passed into Corps Reserve with the rest of the 5^th Marines, but maintained its positions as a secondary Iine.

Although the downpour on 4 June had forced General del Valle to cancel the attack of 1/1 scheduled for 1400 that afternoon, the 7^th Marines on the right had already jumped off.     An hour later, the cancellation order was rescinded, and Lieutenant Colonel Shofner’s Battalion was again ordered to attack, to contact the 7^th Marines, and to seize its Original Objective—the high ground north of Iwa and Shindawaku.

At 1630, the Assault Companies of 1/1 moved out to secure their target, some 1,500 yards away.    The route of attack was up a valley floor, at the end of which a number of lesser hills rose in front of the objective.     A creek that ran east to west across the valley was not visible from the LD; but a Map Reconnaissance indicated that the assault forces would be able to cross it with little difficulty.     The Marines met no opposition after jumping off until reaching the “creek,” now swollen into a raging torrent by the day’s rains.    It presented a formidable barrier to further progress.     A reconnaissance of the stream banks uncovered a rudimentary bridge for carts to the left of the Battalion position.    The Assault Troops were ordered to move upstream, cross the bridge, and redeploy on the other side.

As soon as the first Marine elements had crossed and were wallowing in mud towards firm ground, the heretofore-silent Japanese opened up with mortars and point-blank machine gun fire, sweeping the ranks of the on surging troops.    The Marines pushed on, nonetheless, and two Platoons made it across to the south bank of the creek, only to become pinned down.

The 7^th Marines on the right was unable to negotiate the swiftly flowing waters and was held up on the north bank, and the bridge-crossing site was fully covered by enemy defensive fires coming from a 200-foot-high ridge in front of 1/1.     Therefore, the Battalion Commander ordered his troops to withdraw to the sector of 2/5 for the night.   Because 1/1 had sustained a number of casualties, a Covering Force remained behind to evacuate the wounded after dark.     The next morning, the 1^st Battalion was ordered to bypass the enemy strongpoint by swinging into the Zone of the 96^th Division and follow closely in the trace of the 3/1 attack on Iwa.

Colonel Mason anticipated the problem of maintaining radio and wire contact with his Battalions as they raced south.    His movement order provided that, in case of a complete communications breakdown between Regiment and the Assault Battalions, the most senior Battalion Commander of the committed units would assume Tactical Command overall until contact was established with Regiment once more.    Following a mud-slogging and wearying march south on 5 June, 50 men from 1/1 dropped out of ranks from exhaustion.    During the trek, the Battalion lost contact with Regimental Headquarters for a brief time and temporarily came under control of Lieutenant Colonel Ross.

Out of contact with Regimental Headquarters from the time he had led his Battalion south from Shuri, and with the Battalion Objective yet uncaptured, Lieutenant Colonel Ross decided to complete his mission nevertheless.     He took his Command Group forward early in the morning of 5 June to make a visual reconnaissance of the target.   While this inspection was taking place, the Marines of 3/1 built fires in an attempt to warm themselves and dry as much of their clothing as possible before mounting the attack.   Prior to the jump-off, 3/1 received 19 Supply Air Drops from VMTB–232 aircraft.   In between the day’s intermittent showers, the squadron flew a total of 41 resupply sorties; its all-time high to that date.    The Battalion departed its bivouac area at 1030 and arrived at the assembly area shortly thereafter; Lieutenant Colonel Ross then issued his attack order for the capture of the Iwa-Shindawaku ridge.

Before jumping off at 1230, 3/1 learned that patrols from 2/383 had passed through Iwa without opposition.    As soon as the Marine attack began, lead elements were held up for a short time by sporadic machine gun and sniper fire, but took the ridge before dark.   In the two days spent to envelop the objective, the Battalion had travelled more than 3,000 yards.    By this time, the advance CP of the Regiment had moved far enough forward to enable Colonel Mason to issue attack orders personally to his Battalion Commanders.

The plan for the next day’s attack called for 3/1 to continue the advance and seize Shindawaku.    The 1^st Battalion would destroy all bypassed enemy pockets in the Regimental Zone and to the rear of 3/1, and would backtrack to the stream where the 4 June attack had been stymied.

To the relief of all, the rain stopped during the night of 5–6 June.    At dawn of the 6^th, 1/1 moved out of its bivouac east of Iwa, swung down to the village, and then turned north.    At this point, all three of its Infantry Companies formed a Battalion skirmish line over an extremely wide front.    The Marines then swept northward and past the Zone where 3/7 was preparing to attack in a southwesterly direction.     Lieutenant Colonel Shofner’s troops accomplished their sweep at 1400 and then attacked and seized the ridge overlooking the stream.    The few enemy soldiers still manning positions on this objective, not expecting an attack from the rear, were surprised while changing into civilian clothes.     After taking the position with little effort, 1/1 went into reserve near Tomusu.

Because 3/1 had not been resupplied before its attack at 0900 on the 6^th, the 383d Infantry again issued the Marines K-rations; this time, enough to provide each man in the Battalion with one and a half meals.     After jumping off, 3/1 advanced west and reached the outskirts of Shindawaku at 1030, when enemy troops were discovered occupying commanding ground on the ridge running northwest from the village.    By 1800, however, the Battalion had secured the ridge after a brief fight and 2/1 had moved to an area northwest of Iwa.     Although the left flank of 3/1 was tied in with 2/383 for the night, the Marine Battalion had not been able to contact the 7^th Marines on the right.   Early the next morning, 2/1 was moved into position to plug this gap.

During its drive south, the 1st Marine Division was sporadically halted for brief periods before a number of blocking positions organized and manned by small enemy groups.   Each of these -------------

Advancing abreast of and pacing the march of the 7^th Marines to the sea on 7 June, the 1^st Marines also reported substantial gains.    Early in the morning, 2/1 filled the gap existing on the right between 3/1 and 3/7, while 3/1 maintained contact with 3/383.    By 1800, 2/1 was in possession of the height overlooking Zawa, and the 3d Battalion had moved 1,200 yards along the Corps Boundary to occupy the high ground 1,000 yards north of Yuza; 1/1 had moved to Iwa preparatory to relieving 3/1.

All Infantry Battalions had been plagued by the supply situation, but it seemed to members of 2/1 that they had been especially dogged since leaving Shuri.    Their only source of supply had been the Air Drops, and by the time that one could be made, the Assault Companies were several thousand yards forward of the drop zone.    The supplies then were recovered by Headquarters Personnel, who carried them to forward dumps.    At this point, Marines from the Reserve Company would pick up the supplies and carry them to Assault Units.

Sustained by supplies brought ashore by the LVTs, in the continuing good weather of 8 June, 1^st Division troops pushed ahead against perceptibly stiffening resistance.    The 1^st Marines rolled forward; 3/1 secured its Objective near Yuza at 1600, when it was relieved by 1/1 and went into Regimental Reserve near Shindawaku.    Slightly later that day, 2/1 secured the high ground overlooking the Mukue River.     On 9 June, Division Assault Units spent the day probing enemy positions to their front in preparation for a major attack on the 10^th.

Improved weather conditions and correspondingly better road nets over which supply convoys could travel served to release the VMTBs for other assignments.    Following 6 June, when VMTB–232 made 49 drops, ground units requested Paradrop Missions on only eight other days in the rest of the month.    By this stage of the campaign, the Marine pilots had become quite proficient and accurate in Paradrop Operations.    In reference to a drop Major Allen L. Feldmeier’s VMTB–232 had made on 8 June to its soldiers, the 383d Infantry sent him the following message: “Your drops have excellent results.    We received 95 of the 97 packs which you dropped.”    Later in the month, VMTB–131 flew 3 missions totaling 20 sorties in which 70 packs—each averaging 1,000 pounds of food and ammunition—were dropped.    Ground units receiving the supplies reported that they had recovered 90 percent or more of the packs.

Increased enemy opposition arose on 9 June as 1^st Marine Division Units approached the Tera-Ozato area, which had been outposted by the Thirty-Second Army.    Patrols from both the 1^st and 7^th Marine received heavy rifle and machine gun fire while attempting to cross to the south bank of the Mukue Gawa.    Small infiltration groups finally forded the stream, but were unable to advance beyond the bank.    The 2d Battalion, 1^st Marines, sustained moderate casualties during this day’s fighting, but was unable to evacuate them until after dark because accurate enemy fires covered evacuation routes.

In the 7^th Marines Zone, 1/7 relieved 3/7, which then went into Regimental reserve.    No appreciable gains were made as 1/7 Companies mounted two unsuccessful attempts to seize high ground overlooking Tera.    The second effort was repulsed by extremely heavy small arms fire, which forced the Assault Elements to withdraw under the cover of a smoke screen.    On the extreme right of the Division, 2/7 patrols crossed the Mukue Gawa and attempted to seize the ridge north of Itoman, but were thwarted by enemy fire coming from emplacements fronting the 1^st Battalion Zone.    One Platoon of Company E was able to get to the far side of the river where it was pinned down immediately by accurate frontal and flanking fire.

Operating a combination CP-OP while aboard an LVT( A) floating 100–200 yards offshore of the Battalion flank, Lieutenant Colonel Berger had a grandstand view of the fighting.    When he saw that the advance Platoon was pinned down, he went ashore to order the rest of the Company to cross at the river mouth and reinforce the stricken unit.   Steady Japanese machine gun fire prevented the Marines from wading across and shortly thereafter denied passage to troop-laden LVTs attempting the same route.     At nightfall, the Battalion Commander ordered the exposed units to withdraw to the northern bank of the Mukue River under the cover of LVT-(A) fire.

The 2d Battalion jumped off on the 10^th with Companies F and G passing through the night defenses of Company E, dropping onto the beach from the top of a 10-foot-high seawall, and wading 400 yards across the stream mouth to a point on the south bank opposite the ridge.    Shells from LVT(A)s pounded this high ground and Itoman beyond it.     Following this preparation, the Assault Troops scaled the seawall to attack these two Objectives.     Although the Battalion lost five Officers in the first seven minutes of fighting,  the on surging Marines swept over the ridge, through the ruins of Itoman, and on to the high ground beyond the southern edge of the town.

At the same time that the 2d Battalion had crashed through Itoman, 1/7, spearheaded by Company A, made a rapid and unopposed rush to the crest of the hill north of Tera, where the Japanese strongpoint that had opposed the 7^th Marines on the previous day was located.    From this newly gained height, the Battalion called for an Artillery Concentration on the high ground immediately east of Tera.    Battalion 81mm mortars blistered the village with a barrage of white phosphorous shells, burning to the ground all buildings still standing.    Although few Japanese troops were found in the area, numerous dazed civilians, who had miraculously escaped death in the bombardment, were discovered wandering aimlessly among the ruins.    After sending the Okinawans to stockades in the rear, 1/7 prepared night positions and organized for the scheduled 11 June attack on Kunishi Ridge.

By 10 June, the rains had ended and the transportation problem, although not so critical as it had been previously, was still not completely alleviated.    The ground was drying and once-overflowing streams had lowered to a point where the road-construction and bridge-building efforts of the Engineers could open the way to tracked and wheeled vehicles.    Division Engineers had converted oil drums into culverts and built tank fords over the fire-swept Mukue Gawa.    In addition, the Engineers provided round-the-clock maintenance for these fords so that the heavy traffic south could continue unabated.   One especially important ford was built at the point where the Zawa-Tera highway crossed the Mukue.

The task assigned to 1/1 was the capture of Yuza Hill, the high ground approximately 700 yards west of Yuza and about 450 yards directly north of Ozato; 2/1 was to support the attack by fire, while units of the 96^th Division were to provide security to the left flank of the 1^st Marines.    When the tank fords over the Mukue were opened on 10 June, Shermans also moved forward to support the 1^st Marines attack.

Another support element, the 11^th Marines, assisted the infantry assault.    Following a rolling barrage, tank-infantry teams from 1/1 swept onto the western nose of the hill and Company C swarmed up to its crest in the face of blazing enemy machine gun and artillery fire.    The company lost 70 of its 175 men in this charge.    Lieutenant Colonel Shofner’s attack plan called for Company B to follow in the left rear of the lead elements and then to attack straight up the hill after first having worked its way through Yuza into jump-off positions.    Upon reaching the crest, B was to tie in with Company C on its right and with the Army units on the left.     Although the latter had begun the attack abreast of 1/1, Japanese troops entrenched in the extremely well-fortified Yuza Dake escarpment prevented the soldiers from advancing beyond their line of departure.   Company B was unable to move forward because of the intense artillery and mortar fire coming from the front of the Army Zone, and could not help Company C, which was isolated in an exposed and extremely tenuous position.

Late in the afternoon, Shofner sent Company B around to the right to join the Company on the hill.    Both Assault Companies had sustained heavy casualties in the fighting, but C was hit hardest; all of its Officers were either dead or wounded.    More Marines were lost during the night, 10–11 June, as a result of the constant deluge of enemy mortar and artillery fire placed on the hill.     Added to this heavy toll were the casualties caused by grazing machine gun fire coming from weapons emplaced on Yuza Dake.   Twenty more men were wounded in the dawn of 11 June, when at 0400, the Japanese mounted an unsuccessful counterattack.    For the next two days, 1/1 waited on Yuza Hill for the 96^th Division Infantry to reduce the escarpment to the east.    The Marine Battalion had little trouble in maintaining its hill position despite the persistent Japanese artillery fire harassing it the entire time.

While the 1^st Battalion fought to gain its Objective on the 10^th, 2/1 with the help of armor support successfully cleaned the enemy out of the commanding ridge between Tera and Yuza.    The next day, because 1/1 had been stymied on Yuza Hill, Lieutenant Colonel Magee’s Battalion was ordered to capture Hill 69, the commanding terrain feature directly west of Ozato.     At 1030, the closely coordinated tank-infantry-artillery attack began when the Battalion moved out in a column of companies.   Initial progress was rapid, but when the infantry vanguard entered the valley leading to Ozato, well-placed Japanese mortar and artillery concentrations caused many Marine casualties.   As the left flank of the spearhead approached Ozato, enemy machine gun and rifle fire began mowing down the attackers.

These mounting losses gradually slowed the momentum of the Marine assault, which the Battalion Commander attempted to revive by placing a second Company in the line of attack to the right of the first.    Despite the increasing volume of the massed fires provided by 2/1 supporting arms, enemy fire continued unabated.   Disregarding their slowly ebbing strength and the loss of three supporting tanks, the Assault Units surged forward to capture the objective shortly before sundown.    By dark, the Battalion had consolidated the position and set in night defense lines from which it repulsed numerous infiltration attempts and blunted one counterattack before 11 June dawned.

In preparation for the many casualties anticipated during the fighting yet remaining, a light plane landing strip was placed into operation approximately 2,000 yards north of Itoman on 11 June.    It was noted at the time that, for maintaining morale and obtaining immediate medical treatment for critical cases, “the value of this means of evacuating casualties cannot be overstressed.”     Now casualties were flown almost directly from medical clearing stations immediately behind the front to hospitals in the rear, a distance of 12 miles, in an average time of 8 minutes.    This brief flight obviated a long and often body-racking haul in an ambulance jeep over roads that were practically nonexistent.     From 11 to 22 June, VMO–3 and –7 flew out 641 casualties from this strip.

On the same day the landing strip became operational, Colonel Snedeker’s 7^th Marines advanced 400 to 1,000 yards against ever-stiffening enemy opposition.    The 1^st Battalion, having cleared Tera, attacked to gain the high ground immediately south of the village.    After mopping up in Itoman, 2/7 pushed 500 yards southward.    Confronting the Regiment now, approximately 800 yards equidistant from the outskirts of Tera and Itoman, was Kunishi Ridge, to be “the scene of the most frantic, bewildering, and costly close-in battle on the southern tip of Okinawa.”

BATTLE FOR KUNISHI RIDGE

Running from the northeast to the southwest for a distance of perhaps 1,500 yards, the sheer coral escarpment of Kunishi Ridge held Japanese positions which comprised the western anchor of the last heavily defended line in front of Kiyamu.    Both the forward and reverse slopes of the ridge were replete with caves, weapons emplacements, and fortified tombs, all of which reinforced natural defenses provided by the complex and difficult terrain features of the ridge itself.     In front of the 7^th Marines line, a broad valley containing grassland and rice paddies led to this crag and afforded the defenders unobstructed lanes of fire and the attackers little cover and concealment.    Approaching tanks would fare no better than the infantry since they were restricted to two routes leading into the objective area—both covered extremely well by Japanese antitank guns.    One road followed the coast line; the second cut across the center of the ridge at a right angle, dividing it.

Having pushed through Itoman and Tera during the morning of 11 June, 2/7 and 1/7 prepared to continue on to Kunishi Ridge.    Immediately after midday, tank-infantry teams from both Assault Battalions moved out towards the objective.    Two hours later, withering frontal fire from the ridge, enfilade fire from the yet-uncaptured Hill 69, and accurate artillery concentrations on the tanks forced the attack to a halt.    Because of these fires, and more coming from Japanese-held Yuza Dake, the Commander of the 7^th determined that it would be too costly to continue the attack in the daylight, so at 1447, he ordered the assault forces to withdraw.     After making an aerial reconnaissance of the ridge in a low-flying observation plane, Colonel Snedeker concluded that a night attack would be the course of action most likely to succeed.

That afternoon, as the Battalions dug in a night defense and prepared to continue the attack on the following day, the two Assault Battalion Commanders were thoroughly oriented on the general scheme of maneuver at the Regimental CP.    Colonel Snedeker decided to attack straight across the valley, using the road leading into the ridge as the boundary separating the Battalion Zones and the telephone poles bordering the road as a guide.    The Assaulting Battalions were to penetrate the enemy defenses at the point where the road entered the ridge.    There the Battalions were to peel off to their Zones of Attack and roll up the enemy’s line.    Until the hour of attack, 0330, on 12 June, normal Artillery Fires would be placed alternately on Kunishi Ridge and then Mezado Ridge (500–600 yards southwest of Kunishi ), and thereafter only on the latter.   In order to maintain deception and guarantee that the enemy would be surprised, the Division issued an order prohibiting the use of flares and illumination of any kind—except in emergencies—after 0245.

Before the night attack began, however, the Tenth Army decided to employ another type of weapon.    Prior to and following the 1 April assault landings, the Japanese on the island had been subjected to a massive psychological warfare effort in which propaganda leaflets were delivered by aircraft and artillery shells.    Also, Japanese-language broadcasts were directed at the enemy over loudspeakers placed near the front Iines.    For a period of several days preceding 11 June, this war of paper and words had been accelerated and an emphasis placed on the hopelessness of the Japanese position and the futility of continued fighting.    Both the leaflets and the broadcasts called upon General Ushijima to surrender.

On the afternoon of 11 June, General Buckner sent a Tenth Army reception party, fully empowered to negotiate with any Japanese parley group, to the 2/7 observation post overlooking Itoman.    At 1700, all American firing ceased in the 7^th Marines zone in dubious but hopeful anticipation of an enemy party bearing white flags.    No such group appeared, although six Japanese soldiers did surrender about an hour later to Marines in the lines.    The battlefield’s unnatural silence was shattered at 1804 when hostile mortar fire fell on the surrender point and American Artillery resumed fire on Kunishi in answer.

Both Battalions were poised to attack Kunishi Ridge with one Company leading the assault.    At H-Hour minus 1 (0230), Companies C and F proceeded to assembly areas and contacted each other on the line of departure.    At 0500, when reinforcing Companies B and G moved out in their trace, the two Assault Units had already reached the crest of the ridge, achieving complete surprise, Company C, for example, destroyed several small enemy groups in the act of preparing their breakfasts.

At daybreak, while en route through the valley to reinforce the Marines digging in on the ridge, intense enemy fire caught the two follow-up Companies and pinned them down.    It became painfully apparent that the Japanese defenders had quickly recovered from their initial setback.    In no mood to relinquish their hold on Kunishi Ridge without a last ditch fight, they began lobbing hand grenades on the Marines situated in the forward positions.    Here, Company F was consolidating at a point approximately 400 yards due north of Mezado village and was tied in on its left with Company C, whose line was extended some 450 yards to the northeast.

Under the cover of smoke and with the assistance of tanks, the Companies stalled in the valley made three attempts to reach the ridge during daylight on the 12^th.   Meanwhile, the troops already there needed rations, medical supplies, ammunition, and reinforcements; there were wounded to be evacuated also.   Tanks attempting to get into firing positions south of Tera to silence the enemy weapons and relieve the companies pinned down were themselves fired upon, and in fact were unable even to leave the cover of the village.

In midafternoon, the Shermans were pressed into service to carry rations and personnel up to the ridge.    At 1555, concealed in Tera from enemy observation, the tanks were loaded with supplies and Marines for the trip forward.    Before dark, a total of nine tank loads in three runs had carried a Reinforced Platoon of 54 Marines and critical replenishment items up to the line.    By displacing the assistant driver of each tank, it was possible to cram six riflemen inside instead.    On arrival at the ridge, men and supplies were unloaded through tank escape hatches and casualty evacuees embarked in their place.

No further trips to the ridge were possible because of approaching darkness.    In addition, the road leading to the front lines had caved in under the last tank in the column returning from the third trip.    This tank bellied up, and neither the crew nor the casualties inside could leave through the escape hatch.    After Marine mortars had fired a smoke cover for the tank, another came alongside to evacuate the troops it held.    The disabled tank was then disarmed and abandoned for the night.    In all, 1^st Tank Battalion vehicles evacuated 22 wounded from the ridge.

The darkness precluding further tank operations enabled the remainder of the 1^st and 2d Battalion of the 7^th Marines to move to the ridge without incident.    In Regimental Reserve, the 3d Battalion patrolled to the rear and guarded the flanks of the other two.   With three Companies now up front, each of the two forward Battalions extended its lines further.    By midnight, the Battalion Commanders were convinced that their positions were reasonably secure, and reassured that “the large amount of artillery support available could destroy any enemy counterattack which might be made against the initial ridgehead. . . .“     As General del Valle described it, “The situation was one of the tactical oddities of this peculiar warfare.    We were on the ridge.    The Japs were in it, both on the forward and reverse slopes.”

Patrols from the 1^st Marines ranged south along the Corps Boundary and into the outskirts of Ozato on 12 June.    Although furious fighting was then going on in the 7^th Marines Zone, the 1^st encountered relatively little opposition except for sporadic fire from Kunishi Ridge that was placed on cave sealing and mopping-up teams working in the vicinity of Hill 69.    On the following day, combat patrols began reconnoitering towards Kunishi Ridge in preparation for a predawn attack scheduled for the 14^th.

Throughout the Division Zone, all efforts on 13 June were concentrated on preparing for this large-scale operation.    The incessant cannonading of artillery pieces and Naval Rifles gave the forces of General Ushijima in the southern part of the island no respite.   Two rocket launching craft took positions off the southern tip of Okinawa to rake reverse slope defenses of the Thirty-Second Army.    More than 800 5-inch rockets ripped into the towns of Makabe and Komesu in an hour’s time alone.

In the four days following its seizure of Kunishi Ridge, the 7^th Marines was somewhat isolated from other friendly ground units by “No Man’s Valley,” the 800-yard approach to its positions.    This broad expanse was thoroughly covered by the fire of Japanese soldiers infesting the lower slopes and crests flanking the ridge.    Supplies were either Para-dropped or brought in by tanks.    Some Air Drops fell in the valley, “but they were in the minority.”     The rest were right on target and fell into a Drop Zone under Marine control.    Sometimes it was even dangerous for the Marines to recover supply containers in these supposedly safe areas because of the many enemy snipers awaiting such targets of opportunity.    One Japanese sharpshooter alone killed and wounded 22 Marines before he was finally located and eliminated.

Despite the inviting target their sheer bulk offered, tanks had to be used and did yeoman work in hauling supplies forward to the ridge.    On their return trip, they evacuated casualties, some of whom were strapped to the side of the Shermans and then sandbagged as protection against enemy fire.    In the morning of the 13^th, a tank dozer constructed a bypass around the place where the road had caved in on the previous day.    Upon completion of the detour, the lumbering mediums began shuttling back and forth to the ridge.    Some of the tanks placed point-blank fire on enemy ridge positions covering the supply route in the 1/7 zone, and other tanks operated in the 2/7 zone, working over the western end of Kunishi Ridge.    On the supply/evacuation runs, tanks lifted some 50 Marines from Company A to reinforce the rest of 1/7 on the ridge, and took out 35 casualties on the return trip.

During the course of the day, the Assault Battalions continued consolidating their holdings on Kunishi, and 1/7 sent patrols east along the ridge to contact the enemy and uncover his positions.    The Battalion advanced only slightly.    When a Japanese smokescreen obscured Kunishi village to friendly observation, 81mm mortars hammered the area to disrupt enemy activity suspected there.    Shortly after twilight, a group of enemy troops was sighted on Mezado Ridge and was quickly dispersed by a heavy concentration of mortar and small arms fire.    Marines from 2/7 patrolled along the west coast but were soon pinned down by long-range enemy fire coming from the eastern part of the ridge; they had to be withdrawn under the cover of smoke.

An increasing number of tanks became disabled by the accurate fire of AT guns well hidden in the ridge.    A salvo from the main battery of a Supporting Battleship scored four observed direct hits on enemy emplacements, but did little to subdue other Japanese positions in the area.    This particular barrage exploded on targets within 250 yards of friendly troops.

During the night of 13 June, the 1^st Marines was ordered to attack the front of Kunishi Ridge in its Zone before dawn the next day; H-Hour was set for 0330.    Following a 30-minute artillery preparation, 2/1 jumped off with two Companies in assault.    Despite an earlier Division order prohibiting the use of flares by units adjacent to the Assaulting Force before and during an attack at night, the attack area and the attackers were nonetheless illuminated.     Many urgent calls to higher echelons for an immediate ban placed on the firing of flares proved fruitless.     Fortunately, the Marines advanced undiscovered by the enemy and initial progress was unopposed.    By 0500, two Platoons from Company E had reached the topographical crest of the ridge; the Support Platoon and Company Headquarters were stopped well below this point by extremely severe enemy fire.

Half an hour later, Company G had worked one of its Platoons up to a point on the ridge where it tied in with the left flank of Company E.     At daybreak, increasingly active enemy sniping and intense fire on the flanks and rear of the Assault Companies served to isolate these Platoons from the rest of their Battalion.    Tanks then rumbled forward to support the beleaguered Marines, whose casualties were mounting rapidly.    One Company lost six of its seven Officers.     Because routes to the advance positions were under accurate and direct enemy fire, the mediums were again pressed into action to haul supplies up to the line and carry casualties to the rear, much in the same manner as they had for the 7^th Marines elsewhere on Kunishi Ridge.     At the end of the day, an estimated 110 wounded Marines had been evacuated by the tanks.

Even though the enemy attempted to dislodge them, the Marines held onto their tenuous position.    After dark, the Reserve Company was moved up and a perimeter defense was established for the night.    Japanese small arms, mortar, and artillery fire, and recurring showers of hand grenades poured on the Marine positions throughout the hours of darkness.

In addition, the enemy made many attempts to infiltrate all along the line.    As the sun rose on 15 June, 2/1 found enemy pressure to be as constant as it had been the day before, and Battalion casualties reaching alarming proportions.     Although the tanks continued to carry supplies and evacuate the wounded, 2/1 critically needed ammunition and rations.    A requested Air Drop scheduled for 0900 was delayed until the middle of the afternoon, and then more than two-thirds of the packs dropped into enemy territory and could not be recovered.    The efforts of 2/1 Assault Companies notwithstanding, Kunishi Ridge was far from secured when 2/5 relieved 2/1 after dark on the 15^th.

Earlier that day, 3/5 had relieved 1/1 on Yuza Hill, following which, the latter moved to an assembly area near Dakiton; 3/1 had already set up in the vicinity of Shindawaku.   With 2/5 on the line, Colonel Griebel had complete responsibility for the Zone formerly held by the 1^st Marines.

During the afternoon before 2/5 was to go into the lines, its Company Commanders were taken by tank to the front lines to. make a personal reconnaissance of the area they were to take over.    When they arrived at the positions of 2/1, they discovered that the tactical situation precluded a daylight relief.    They also found that 2/1 held only a 75-yard section on the crest of Kunishi Ridge, with a portion of the Battalion occupying a small pocket on the forward slopes, of the ridge.     As a result of this situation, the Commanders of 2/1 and 2/5 agreed that the relief should begin only after it had become dark.    In order to maintain tight control over the move and prevent matters from becoming confused in the restricted area where the relief was to take place, Lieutenant Colonel Benedict decided to commit only one of his Companies initially.    The relief of 2/1 was completed at 2030, a half hour after it had begun.    The 1^st Marines as a whole went into Division Reserve at 2300, after having been in the Division line for 12 straight days during which it suffered nearly 500 casualties.

On the day before fresh troops had joined in the fight for Kunishi, the 7^th Marines resumed its grinding advance by “the slow, methodical destruction of enemy emplacements on the ridge, to which the descriptive word ‘processing’ had come to be applied.”    The 2d Battalion was ordered to seize the rest of the ridge in its Zone and to be prepared to continue the attack to Mezado Ridge.    Company A attacked east to seize the remainder of the reverse slope of Kunishi Ridge within the 7^th Marines Zone, while B and C provided fire support and mopped up behind the Assault Company.   Despite difficult terrain and an unrelenting enemy opposition, Company A succeeded in closing to the outskirts of Kunishi village.

At 1247, Company B was ordered to continue the advance through Kunishi, and then to attack north to secure the forward slope of the easternmost sector of Kunishi Ridge.   Although the Company passed through the village and began heading for the high ground with only slight interference, withering machine gun fire soon pinned down all but two rifle squads, which were able to climb the height.    Once the Marines had gained the crest of the ridge, the Japanese launched a strong counterattack, forcing the squads from their temporary holding.    The company as a whole then withdrew to lines held the previous night.

To the right of 1/7, the 2d Battalion was subjected to increasingly intense enemy fire despite suppressive American counter-barrages; 2/7 reported only limited gains that day.    At 1530, the Logistic and Tactical Support of the 7^th Marines by tanks ended when the armor began assisting the 1^st Marines.    On the 14^th, the tracked vehicles had carried 48 men of the 7^th Marines forward and evacuated 160.

During the following two days, 2/7 was supported by Naval Gunfire, Artillery, Air, Rockets, and 81mm Mortars, which mercilessly pounded the enemy.    Both Gun and Flame tanks furnished direct close-in support, but could make no appreciable dent in Japanese defenses.     A stubborn enemy notwithstanding, 2/7 moved its lines some 500–700 yards to the right and in front of the first high ground leading to the Mezado Hill mass, the Division Objective after Kunishi.

The 1^st Battalion fared no better in its attempt to seize the rest of Kunishi Ridge in its Zone on 15 June than it had on the 14^th.     Notified that 15 Artillery Battalions were on call for supporting fires, 1/7 moved out at 0945 following an Artillery Preparation and preliminary patrolling.    Company C attacked directly east along the ridge while B moved through Kunishi village and then turned north towards the high ground again.

Heavy Japanese fire from prepared emplacements prevented the Marines from advancing across the open ground between the village and the ridge line, and Company C was unable to relieve the pressure on B.     At 1600, the two units were withdrawn once again to positions held 13–14 June.

During the night 15–16 June, small enemy groups were active in front of 1/7 lines harassing the Marines with small arms fire and lobbing hand grenades into their foxholes.    Before dawn on 16 June, the troops on the left (east) flank were pulled back to the west approximately 200 yards to permit a massive Artillery Preparation on the Objective which had stymied 1/7 the preceding two days.    An extremely heavy concentration of artillery, mortar, and rocket fire drummed that day’s target for nearly three hours before the Assault Forces jumped off.     By 1345, 1/7 had completely seized the rest of the ridge in its Zone and immediately began mopping up and consolidating its newly won ground.    Shortly thereafter, Battalion troops “repeatedly encountered and destroyed numerous groups of the enemy wandering through the town of Kunishi in a confused, disorganized, and bewildered state.    It was evident that the end was not far off.”

One other major accomplishment that afternoon was the capture by Company A of “The Pinnacle,” a particularly difficult enemy strongpoint situated so that it could be neither destroyed nor neutralized by any type of support weapon immediately available.    It was in this area that the enemy sniper who had shot 22 Marines earlier was hunted down and killed.    Approaches to The Pinnacle were swept by Japanese fire, and its seizure by the infantry was slow, tortured, and costly.

To the right of 1/7, the 2d Battalion lines were extended some 400 yards further west to where the Battalion held the first high terrain approaching the Mezado hills.    This progress was accomplished even while the Battalion had sustained heavy casualties and lost its valuable armored support, which fell victim to Japanese land mines and 47mm AT guns.    Expert employment of its supporting arms enabled 2/7 to make slight gains on the 16^th.     For example, salvos from the main battery of USS Idaho were called down on targets located within 400 yards of frontline troops.     In addition, Air Liaison Parties controlled air strikes, often consisting of 25–30 planes each, which successfully destroyed stubborn pockets holding up the advance.

No longer was Kunishi Ridge a major obstacle in the way of the 1^st Marine Division, for the terrain that the Japanese had so doggedly defended here, including the approaches to Mezado, had been virtually cleaned out by the end of 16 June.     Only that portion of the ridge on the far left of the Division, in the 5^th Marines Zone, still presented some problems.    With the reduction of enemy opposition on The Pinnacle, the 7^th Marines was able to make physical contact with the 5^th.

As 1^st Division troops prepared for the final drive south, mopping up operations on Oroku Peninsula neared an end.     Concurrently, General Shepherd’s staff drew up plans for the eventual commitment of the 6^th Division in the southern front.     Initially, the 22d Marines was to pass through right flank elements of the 7^th Marines on 17 June to relieve 2/7; 3/7 would come out of Reserve to relieve the 1^st Battalion.

In the 5^th Marines Zone on 16 June, 2/5 attacked at 0730 and spent the day working over that portion of the Regimental area that lay between Kunishi Ridge and Hill 69.     At approximately 1800, a Reinforced Company reached the crest of the ridge and tied in with the left flank unit of the 7^th Marines.    Bitter, close-quarter fighting had been the order of the day for 2/5, whose Assault Companies had received continuously heavy small arms fire.    Rising casualty figures again required tanks to be employed as evacuation vehicles; this task was in addition to their shuttling ammunition and rations forward.    In face of Japanese holding action to its front, 2/5 made slow but steady progress.

Although enemy infiltrators attempted to breach 5^th Marines lines during the night 16–17 June, they were thoroughly discouraged.     As 2/5 resumed the attack on the 17^th, oppressive enemy small arms fire coming from the vicinity of Aragachi in the XXIV Corps Zone punished the front and flank of the Battalion.    Its task was to seize that portion of Kunishi Ridge still held by the enemy.    Attacking with a two-company front, the 2d Battalion faced the problem of coping with Japanese reverse-slope positions and destroying them.    To smooth the way somewhat, a rocket barrage was laid on the  objective.     A short time later, at 1030, tanks moved out and clambered over the ridge route, which had been opened earlier by an Armored Bulldozer.

Murderous enemy fire criss-crossed the crest of the ridge as 2/5 grimly pushed on.     All tanks were pressed into action as Armored Ambulances once again, but only the walking wounded could be taken inside of the vehicles and evacuated.    Stretcher cases presented a serious problem because they could not be taken up through the tank escape hatches, but had to be lashed to their rear decks.    Often, wounded were hit a second and third time on their trip to the Aid Station.

Throughout the afternoon, the volume and intensity of enemy fire as well as the ferocity of the enemy opposition remained undiminished.    Tank, artillery, and mortar fire, and the ripple fire of several rocket barrages were directed at suspected Japanese strongpoints and weapons emplacements in an attempt to open the way for Marine tank-infantry teams.    At 1700, Lieutenant Colonel Benedict decided to commit his Reserve Company and further strengthen the Assault Companies by sending forward 133 replacements, which had been assigned to the Battalion three days earIier.

With this infusion of fresh troops in its line, 2/5 surged eastward along the ridge; by nightfall, the Battalion held approximately three-fourths of the 1,200 yards of Kunishi Ridge in the Regimental Zone.    Because the position of the Battalion was somewhat precarious, at dusk Colonel Griebel attached Company K, 3/5, to the 2d Battalion with a mission of protecting the Battalion rear.    At 2315, an estimated Company-sized counterattack hit 2/5 positions, but was thoroughly blunted; Company K troops killed the few Japanese that succeeded in penetrating the lines.

On the coastal flank of the IIIAC Zone, 6^th Division Marines had become fully involved in the drive to the south by the end of 17 June.     Moving forward during the afternoon of the previous day to relieve 2/7, the 1^st and 3d Battalions of the 22d Marines attempted to cross the valley between Itoman and Kunishi, but were forestalled by the severe enemy fire covering this route.    Forced to turn back to their previous positions, the two Battalions waited until dark to begin the relief.     The uneventful passage of the lines began at 0300, 17 June, and by dawn Assault Elements were in jump-off positions at the base of the northern slope of Mezado Ridge, prepared to attack at 0730 in coordination with 3/7 on the left.

An Artillery, Naval Gunfire, and Air Bombardment of Mezado Ridge, and of Hill 69 and Kuwanga Ridge beyond it, preceded the attack.    Once the fires had lifted, the 22d Marines moved out with two Assault Battalions abreast—3/22 on the left.     Machine gun and intermittent mortar fire paced the advance up the slope of the ridge, but as the morning wore on, the Marine progress became increasingly difficult in the face of stiffening resistance.

To support the attack of 1/22, 6^th Division tanks moved around the right flank of the Regiment and through the water towards an off-shore reef to gain Firing Positions commanding direct observation of the caves on the western tip of Mezado Ridge.     As one Armored Platoon began to negotiate the route, the unexpected depth of the water prevented it from working its way forward far enough to enfilade the ridge, and its tanks were forced to deliver supporting fire from the most advanced points that they had been able to reach.    Tank weapons could not suppress the heavy machine gun fire coming from the reverse slope of the hill mass holding up 1/22.     As a result, the Battalion was unable to gain more than a foothold on the forward slope of Mezado Ridge until 1700, when it positioned two Companies on the crest of the ridge for night defense.

Inadequate maneuvering room to the front also limited the employment of supporting armor.    Besides the flank route through the water, the only other suitable tank road ran through a rice paddy which had been cratered in four places and heavily mined as well.   Once the mines were removed or neutralized, tanks lumbered up to these craters and dumped into them bundles of large logs that had been attached to their front slope plates.    Tanks and logs instead of dump trucks and fill dirt were used to plug the craters because only armored-plated vehicles could weather the severe enemy fires.

After two craters in the road had been filled, it was discovered that the approaches to a small bridge further up the road had been mined.    Sniper and machine gun fire prevented Engineer Clearing Teams from neutralizing the mined area, and the road project was abandoned temporarily.    Nonetheless, the tanks advanced as far forward as possible to deliver overhead supporting fires.

By noon, 3/22 had secured the highest point on the ridge and maintained the momentum of its attack to clean out the town of Mezado as well.     Before dusk, the Battalion had captured the key terrain around Hill 69 and was in command of the ground overlooking the next Objective, Kuwanga Ridge.     With the exception of an attempted enemy counterattack in the sector of 1/22 at 2210, a generally quiet night was passed by the 22d Marines.

When 1^st Division troops jumped off on the 17^th, 3/7 attacked in a column of Companies, Company K leading, to take the Hill 69 east of Mezado.    Company I maintained contact with the 22d Marines, and Company L took up positions to protect the left flank of K.    Following an unopposed 1,400-yard drive across the plateau just east of Mezado to seize Hills 69 and 52, 3/7 halted for a short time to reorganize, and then attempted to continue the drive to the crest of Hill 79—the last remaining barrier before Makabe.    Heavy Japanese fire from positions on the high ground commanding the Kuwanga-Makabe road forced the Battalion to dig in for the night before it could gain the hill.    Once dug in, 3/7 Marines quickly organized to blunt all enemy attempts to infiltrate and counterattack in the darkness.

When the Japanese 22d Regiment did launch its counterattack, it was directed against 1/22.    This determined effort born of despair was doomed from its inception because that portion of the enemy Regiment scheduled to exploit the counterattack had been almost completely destroyed that afternoon.     In effect, the near annihilation of the 22d Regiment meant that the left flank of the Japanese outpost line had all but collapsed, and that the 32d Regiment, holding positions near Makabe, was faced with the threat of having its left flank rolled up.

The Marines were prepared to turn this threat into reality by exploiting the successes of 17 June with the commitment of fresh troops into the battle on the next day.     While the 7^th Marines finished “processing” Kunishi Ridge, the 8^th Marines (Reinforced), Commanded by Colonel Clarence R. Wallace, prepared to relieve 3/7 to continue the attack southward.    Before the dawn of 18 June, this 2d Marine Division infantry Regiment, now attached to the 1^st Division, entered the lines.

IHEYA-AGUNI OPERATIONS

After its feint landings on the southeastern coast of Okinawa on L-Day and L plus 1, the 2d Marine Division remained on board its transports which steamed in the vicinity of the target area until 11 April.    On that date, the Demonstration Group set out for Saipan, arriving there four days later.    On 14 May, CinCPac ordered the Division (less one RCT) detached from the Operational Control of the Tenth Army and designated it as the Area Reserve under control of CinCPOA.    In addition, General Watson received an alert for his Division to conduct Phase III (d) of the ICEBERG Plan, the landing on Kikai Jima.    Once captured, this small Island north of Okinawa was to be utilized as a northern outpost for the Ryukyus area, and was to base four Fighter Groups, two Night-Fighter Squadrons, and one Torpedo-Bomber Squadron.    The 8^th Marines (Reinforced) remained under the control of General Buckner for the impending landings on Iheya and Aguni Shimas, and was ordered to re-embark immediately.

For the entire month after its arrival at Saipan, the Division remained on board the transports.    A warning order for the Kikai Invasion had been issued on 6 May, but this alert was reduced in urgency four days later by a message that indicated that Phase III (d) might not be conducted.    With the arrival of the 14 May message releasing the Division from Tenth Army control, the Marines began unloading and rehabilitating their equipment ashore in preparation for the time when it was to be ordered to mount out for Kikai.    On 3 June, the landing was deferred for an indefinite period, and on the 19^th, the 2d Marine Division (less RCT 8) was released from its role as Ryukyus Area Reserve and reverted to the control of FMFPac.

Once again, on 24 May, the 8^th Marines departed Saipan headed for Okinawa; its eventual target, the Islands of Iheya and Aguni.    Because of the heavy damage that had been sustained by the fleet and especially the radar pickets during Kamikaze raids, early in May Admiral Turner asked General Buckner to begin a study of outlying Islands to determine where long-range radar and Fighter Director Facilities could be installed.   Resulting from this study was the decision that Tori, Aguni, Iheya, and Kume Shimas could be captured in that order.    A special landing force, a Reinforced Company from the 165^th Infantry, made an unopposed landing on Tori on 12 May and a detachment from Air Warning Squadron 1 began operations almost immediately.

Since the Okinawa campaign was now reaching a crucial stage, General Buckner believed that the forces already committed in the fight southward should not be diverted to such secondary actions as the proposed landings on the other outlying Islands noted above.    He requested, therefore, that the Reinforced 8^th Marines be returned to Okinawa to effect the Iheya-Aguni landings.    Brigadier General LeRoy P. Hunt, ADC of the 2d Marine Division, was designated the Landing Force Commander for these operations.    Flying to Okinawa with key members of his staff on 15 May, General Hunt spent the 16^th and part of the 17^th conferring with Tenth Army Staff Officers about the proposed operation plan.    By 30 May, when the 8^th Marines arrived at Okinawa, a complete Naval Gunfire and Air Support schedule had already been established, and detailed contingency plans drawn up to meet any situation that might arise from enemy sea or air action.

The attack force, Commanded by Admiral Reifsnider, steamed from the Hagushi Transport Area early on 2 June and set a course for the target, located 15 miles northwest of Hedo Misaki.    The bombardment prior to the H-Hour of 1015 proceeded as scheduled; 2/8 and 3/8 landed on Iheya 27 minutes later.    Neither enemy opposition nor enemy troops were encountered.     The Marines only found some 3,000 confused but docile natives who were taken under tow by military government teams supplied by the Tenth Army Island Command.    Late in the afternoon of the 3d, the troops began general unloading and the Island was officially declared secure the next day.

The landing on Aguni Shima, 30 miles west of Okinawa, was delayed until 9 June by inclement weather.   On that day, 1/8 went ashore under circumstances similar to those found at Iheya.    The only Marine casualties of the two Amphibious Assaults were sustained at Iheya; 2 Marines were killed and 16 wounded by aerial rockets and short rounds of Naval Gunfire.    In accordance with the instructions it had received from Tenth Army before the operation, the 8^th Marines stood ready for immediate commitment on Okinawa upon completion of the two landings.    When fresh units were needed for the final thrust against the Japanese dug in on Kiyamu Peninsula.    Colonel Wallace and his troops were available.

THE FINAL PUSH

By 4 June, the remnants of the Thirty-Second Army had fully manned the outpost line of Kiyamu Peninsula.   Concentrated in this area were approximately 30,000 Japanese troops, distributed as follows: 24^th Division and attachments, 12,000; 62d Division and attached units, 7,000; 44^th IMB and attached units, 3,000; 5^th Artillery Command and attached units, 3,000; and troops attached directly to Thirty-Second Army Headquarters, and the Command itself, 5,000.    “Attrition during Retirement Operations,” was the official Japanese explanation for the 20,000-man differential between their estimated strength figure of 50,000 in late May and the total number of effective available at the beginning of June.

Of General Ushijima’s remaining forces, approximately 20 percent were survivors of the original, first-rate Infantry and Artillery Defense Garrison; the rest were either untrained rear echelon personnel or Boeitai.     Leading this motley force at Battalion level and above were many of the Original Senior Commanders who had remained alive and were still capable of arousing a fighting spirt in their men.

Their unflagging belief in a final Japanese victory was unrealistic in view of the alarming losses of weapons and equipment that the Thirty-Second Army had sustained since the American landing on 1 April.    Hand grenades and explosives either were in short supply, or in the case of some units, non-existent.     Only 20 percent of the original number of heavy machine guns owned by the army remained, and few of its heavy Infantry cannon and mortars were still firing.     Although the Army ammunition supply along with two 150mm guns, sixteen 150mm Howitzers, and 10 antiaircraft artillery pieces had been transported south to Kiyamu when Shuri was abandoned, the stock levels of artillery ammunition precluded more than 10 days of sustained firing.

Despite these outward signs of its imminent defeat and impoverished condition, the belief held by General Ushijima’s Army in ultimate victory was derived from deep-seated tradition, strongly enforced discipline, and the historically pervasive influence of Japanese military doctrine throughout the Empire.    These intangibles, almost completely alien and incomprehensible to Americans, promised that Kiyamu Peninsula was not to fall and the battle for Okinawa was not to end before a final, violent climax.

Influenced by the location and relative strength of enemy strongpoints facing the Tenth Army, and the availability and status of his Assault Forces, General Buckner had shifted the Corps Boundary west on 4 June.     In the now-narrower IIIAC zone, General Shepherd’s Division sought to capture the Oroku Peninsula while the 1^st Marine Division was to cut off the peninsula from the rest of the Island, capture Itoman, seize both Kunishi and Mezado Ridges, and drive to Ara Saki, the southernmost point of the Island.   The assignment given XXIV Corps included the capture of the Yuza Dake-Yaeju Dake Escarpment as a Primary Objective.    On line facing this foreboding terrain were the 96^th and 7^th Divisions.

Nearly two weeks of punishing and brutal fighting were to ensue before the two Army Divisions could eliminate all enemy resistance in this Thirty-Second Armv defense sector.     XXIV Corps Units spent the period 4–8 June in regrouping and attempting to gain favorable jump-off positions for the attack on the escarpment on the 9^th.    All supporting arms were employed to soften the well-organized enemy defense system.    Armored Flamethrower, tank, assault gun, and artillery fires were added to the point-blank blasts of experimental 57mm and 75mm recoilless rifles in an effort to reduce the natural bastion.

The defense of the Yuza Dake-Yaeju Dake outpost line had been assigned to two units.   Guarding the escarpment from Hill 95 on the east coast to Yaeju Dake was the 44^th IMB; the remainder of the high ground, including Yuza Dake, was the responsibility of the 24^th Division.    Added to the tenacious determination of the foe was the natural, fortress-like quality of the terrain he guarded.    This combination enabled the Japanese to defend the Yuza Dake area with only one Regiment, the 89^th.

Facing the 7^th Division were enemy troops who compared unfavorably with the veterans defending Yuza Dake.    Coming from miscellaneous Shipping Engineer, Sea Raiding, Mortar, and Line of Communication Units, the soldiers were loosely organized into Provisional Infantry Regiments and put into the 44^th IMB line.    The vital Hill 95-Nakaza Valley area was held by survivors of the 15^th Independent Mixed Regiment, which first began to give way under the repeated pounding of the 7^th Division attack.    General Arnold’s soldiers relentlessly pushed forward on 11 June, the second day of the all-out Corps Assault on the escarpment, and threatened the rest of the Thirty-Second Army line by breaking into the 44^th IMB defenses.     An attempt by General Ushijima to shore up this section of his rapidly crumbling outpost by committing Jerrybuilt Infantry Units comprised of service and support troops proved to be “as ineffective as throwing water on parched soil.”

The 89^th Regiment continued to withstand the inroads of 96^th Division Infantry on 12 June, but this day marked the beginning of the end for the 44^th Independent Mixed Brigade.    Although it had been reinforced with two Battalions from the 62d Division as a result of the Brigade Commander’s urgent pleas, the time for decision was already past, as was the chance for these newly committed units to affect the ultimate course of the battle.

Clear weather on 13 June, following a night of abortive enemy counterattacks, permitted General Hedge to employ fully all of his supporting arms.    Units of the 62d Division attempting to reach and revive the hapless 44th IMB were themselves blasted by American Air, Artillery, and Naval Gunfire.     Although the 89^th Regiment—reinforced by the 24^th Reconnaissance Regiment— still maintained its hold on Yuza Dake, its rear and flank were threatened this day by the impending penetration south of Yaeju Dake.  Further advances on 14 June forced General Ushijima to commit the 13^th Independent Infantry, which was almost immediately smashed by 7^th Division troops.     Also committed and destroyed on the 14^th were the remaining Reserve Battalions of the 62d Division.

Elsewhere, as Japanese positions began to give way under the pressure of the American onslaught, Thirty-Second Army Headquarters lost all contact with the 15^th  IMR—the last Infantry element of the 44^th IMB able to maintain unit integrity.    To stave off the last stages of a crushing defeat, General Ushijima ordered the 62d Division into the deteriorating Japanese line from reserve positions southwest of Makabe, but a savage lashing from American Artillery, Naval Guns, and Air-delivered Napalm and bombs thoroughly disrupted the deployment.    Few, if any, of the enemy troops arrived at their destination.

The 96^th Division took advantage of this confused situation to rush its Infantry through the Yuza Dake perimeter.    On the left, the 7^th Division surged down the coast.    By the end of 17 June, XXIV Corps Regiments held firm control of all commanding ground on the Yuza Dake-Yaeju Dake Escarpment.    Compressed between the front lines of the Corps and the southern tip of Okinawa were the remnants of the Thirty-Second Army—a hedge-podge of units and individuals from the 62d Division, 44th IMB, and 24th Division.    Before the Island had been secured by the Tenth Army, most of these Japanese troops would die violently in a forlorn attempt to protect the Headquarters of General Ushijima.

DEATH OF AN ARMY

The death throes of the Thirty-Second Army became even more obvious as the Tenth Army advanced against steadily lessening resistance on 18 June.    Although most sections of the Japanese line proved softer than before, two isolated centers of opposition developed during the day—one around Medeera and the other in the area of Mabuni.    The first was held by the remnants of the 24^th Division, and the second, around Hill 89, was defended by elements of the Headquarters and troops of the remaining Thirty-Second Army units.

Leading the 1^st Marine Division attack was the 8^th Marines, which had relieved the 7^th Marines the previous night.    At 0730, 2/8 (Lieutenant Colonel Harry A. Waldorf) jumped off from Mezado Ridge to head south and occupy a line west of Makabe from which it could launch a “quick decisive thrust” to the sea.    Light machine gun and rifle fire, later mixed with sporadic mortar and artillery rounds, hit the left front and flank of the Battalion as it made a rapid 1,400-yard advance to cap its first day in the lines.    By dark, the Battalion had secured its objective and began digging in for the night.    Since its left flank was well forward of 1/5, Company B, 1/8, was attached to fill the gap.

Early on 18 June, General Buckner had gone forward to witness the fighting, and “probably chose the 1^st Division front on this date because he wanted to see the 8^th Marines in action,” as he thought well of the Regiment.    As General Oliver P. Smith recalled:

On his way to the front [to the 3/8 OP], General Buckner met Bob Roberts (Colonel Harold C. Roberts, Commanding Officer of the 22d Marines).   Roberts urged General Buckner not to go to the front at this particular point as the rapid advance had bypassed a good many Japanese, and, further, there was considerable flanking fire coming from the high ground in front of the 96^th Division.   General Buckner did not heed this advice. (Roberts was killed an hour or so later on another part of the front.)   The General got up on a ridge where Lieutenant Colonel Paul E. Wallace [Commanding 3/8] had an OP.  Tanks and infantry were operating ahead.   A Rifle Company was on the ridge preparing to move forward.   General Buckner took position behind two coral boulders separated by a slit through which he could look.   His position was slightly forward of the crest.   He had not been in this position long when a Japanese 47mm shell hit the base of the boulders.   The first shell was followed by five more in rapid succession.   Either a fragment of the first shell or a piece of coral rock thrown out by the detonation hit General Buckner in the chest.   This wound was mortal.   Hubbard [General Buckner’s aide], with the assistance of others in the vicinity, dragged General Buckner over the crest to a defiladed position.   A Navy Hospital Corpsman was there and a doctor arrived within three minutes.   Plasma was available, but the General had lost blood so rapidly that plasma could not save his life.

Upon being informed of General Buckner’s death, Brigadier General Elwyn D. Post, Tenth Army Chief of Staff, sent a message to CinCPOA reporting the death.    In addition, General Post, knowing General Buckner’s expressed desires concerning the Succession of Command, recommended in the message that General Geiger be designated the new Tenth Army Commander.    On 19 June, General Geiger was appointed a Lieutenant General and was officially designated Commanding General, Tenth Army (CTF 56), the same day, making him the Senior Officer present on Okinawa.    This was the first time that a Marine Officer had Commanded a unit of this size.    General Joseph W. Stilwell, U. S. Army, former Deputy Commander of the Southeast Asia Command, arrived on the Island at 0700, 23 June, succeeding General Geiger the same day, after the Marine General had successfully directed

the final Combat Operations on Okinawa.

Early in the morning on which General Buckner died, the 5^th Marines was to take Hill 79, northwest of Makabe.    At dawn, 1/5 moved out around the western nose of Kunishi Ridge and then south through the 8^th Marines Zone in order to get into positions to jump off at 0730.    As soon as the attack began, the Assault Units were pinned down by fire coming from the objective and unable to move until 1100, when tanks arrived and rumbled into support positions.    A coordinated tank-infantry assault was launched soon after, and the Marines were on the hill by noon.    Following in the wake of the attack was 3/5, up from reserve, which moved into support positions behind the 1^st Battalion for night defense.

Enemy AT fire forced the Marine tanks to operate cautiously, but did not slow them down.    Artillery-delivered smoke on a suspected antitank gun position on Hill 81 just north of Makabe blinded the enemy gunners and permitted the Shermans to operate without being fired upon.    Other AT guns were destroyed during the day after having been spotted from the air by an experienced tank officer, who was flown over the battlefield for that purpose.    By dark, 1/5 had gained the lower slopes of Hill 79 with armored assistance, but could not advance beyond that point because of heavy enemy fire from high ground in the 96^th Division Zone and Hills 79 and 81.    At the end of the day, tank-infantry teams from 2/5 eliminated the last large pockets of enemy resistance on Kunishi Ridge, and dug in on commanding ground for the night.

In the 6^th Marine Division Zone, 2/22 passed through the lines of 3/22 on 18 June to attack Kuwanga Ridge.    Moving rapidly ahead despite steady automatic weapons fire, the Battalion gained a foothold on the high ground and began simultaneous drives to the east and west to clear the ridge of enemy.    Although fired upon by rifles, machine guns, and mortars, the Battalion possessed the greater part of the ridge before mid-afternoon.    At this time, General Shepherd saw that the understrength 2/22 was spread too thinly over the 1,800 yard-wide ridge to withstand a concerted enemy counterattack, so he ordered the 4^th Marines to attach one Battalion to the 22d for night defense; Colonel Shapley ordered 3/4 forward.

The other two Battalions of the 22d Marines spent the day hunting down and destroying numerous enemy groups infesting the reverse slopes of Mezado Ridge.    Forward observation posts became especially plagued by all sorts of fire coming from these bypassed Japanese soldiers.    Colonel Roberts, the Regimental Commander of the 22d Marines, was killed at his OP by sniper fire at 1430.    The Regimental Executive Officer, Lieutenant Colonel August Larson, assumed command.

Assault forces of XXIV Corps also made important gains on the 18^th.    The 96^th Division push on Medeera positions from the east was coordinated with the 1^st Division attack on the same objective from the west.    The 7^th Division continued its drive with a two pronged attack.   One assault element dashed down the reverse slope of Hill 153 to sweep past Medeera and ended its attack at the Corps Boundary near Komesu.    Three Battalions abreast spearheaded the second prong of the attack, advancing slowly down the coast towards Mabuni.    During the night of 18–19 June, at least 340 Japanese soldiers were killed in attempted infiltrations and scattered attacks all along the Tenth Army front.

With the realization that “his Army’s fate had been sealed,” General Ushijima began spiritual and physical preparations for a Samurai’s death.    On 16 June, he sent the first of his farewell messages, this a report to lGHQ in Tokyo, which read:

With a burning desire to destroy the arrogant enemy, the men in my command have fought the invaders for almost three months.  We have failed to crush the enemy, despite our death-defying resistance, and now we are doomed.  Since taking over this island our forces have, with the devoted support of the local population, exerted every effort to build up defenses.  Since the enemy landing, our air and land forces, working in concert, have done everything possible to defend the island.

To my great regret we are no longer able to continue the fight.  For this failure I tender deepest apologies to the emperor and the people of the homeland. . . . I pray for the souls of men killed in battle and for the prosperity of the Imperial Family.   Death will not quell the desire of my spirit to defend the homeland.  With deepest appreciation of the kindness and cooperation of my superiors and my colleagues in arms, I bid farewell to all of you forever.

Mitsuru Ushijima

Three days later, he sent a last message to all Thirty-Second Army units with which he still had contact, congratulating the survivors on having performed their “assigned mission in a manner which leaves nothing to regret” and calling upon them “to fight to the last and die for the eternal cause of loyalty to the Emperor.”    General Ushijima then directed most of his Staff Officers to leave the Mabuni Command Post, to disguise themselves as Island natives, and to infiltrate the American lines in order to escape to northern Okinawa.    Some of his key advisors, like Colonel Yahara, were assigned the mission of reaching Japan in order to report to Imperial General Headquarters; others were ordered to organize Guerrilla Operations in the rear of Tenth Army Tactical Units and the Island Command.

Despite their having been thoroughly indoctrinated with the tenets of Japanese military tradition, there were some enemy soldiers who did not particularly wish to die for Emperor and Homeland.    Psychological Warfare Teams had Interpreters and Cooperative Prisoners broadcast surrender inducements in Japanese over loudspeakers mounted on tanks operating at the 7^th Division front and on LCIs cruising up and down the southern coast.    These broadcasts successfully convinced 3,000 civilians to surrender.

A more significant result of these messages occurred on 19 June, for instance, when 106 Japanese soldiers and 283 Boeitai voluntarily laid down their arms and gave up in the face of the 7^th Division advance.    At this stage of the campaign, the broadcasts influenced increasing numbers of the enemy to surrender as the conviction that all was lost and their cause was hopeless sank into their war-weary minds.

Their forward progress now slowed by fleeing civilians as well as the entrenched enemy, 7^th Division troops, nonetheless, advanced to within 200 yards of the outskirts of Mabuni by nightfall of 19 June.    Tanks accompanying the Assault Infantry placed direct fire on caves fronting Hill 89, not knowing that at that very time, General Ushijima was giving a farewell dinner for his departing staff officers.

Farther inland, on the right of the Division Zone, 184^th and 381^st Infantry Units drove towards Medeera from the south and east against considerably lessened fire and resistance.    Nevertheless, small fanatic groups, defending the complex terrain protecting the 24th Division Headquarters, had to be overcome before the major objective could be seized.    To the northwest of Medeera, 96^th Division soldiers pushing towards Aragachi from the north found the same enemy reluctance to withdraw, encountered elsewhere along the Tenth Army front, before they could reach the high ground overlooking the village.    While observing the 384^th Infantry fighting to gain these heights, the ADC of the 96^th Division, Brigadier General Claudius M. Easely, was killed by enemy machine gun fire.

The advance of IIIAC Assault Forces on 19 June was highlighted when the 8^th Marines completely penetrated Japanese defensive positions to reach the sea.    Less successful, however, were the efforts of the 5^th Marines in a day-long attack on Hills 79 and 81.    With a company of tanks in support, 1/5 jumped off at 0730 to take Hill 79 first and then 81.    Despite the direct fire placed on the initial objective by the Shermans and M–7s, the Battalion was unable to take Hill 79 and was forced to return to positions held the previous night.

As he observed the course of the fighting and judged that neither Hill 79 nor 81 were going to be taken, Colonel Griebel ordered 2/5 to take the latter from the south in order to lift some of the enemy pressure on 1/5.    Lieutenant Colonel Benedict’s 2d Battalion, which had been relieved on Kunishi Ridge at 1315 that day by 3/7, moved out in a march column at 1515, made a wide swing to the southwest through the 8^th Marines Zone, and halted at a point some 300 yards southwest of Hill 79 at 1700.    Moving out some 15 minutes later, the Battalion headed towards Makabe preparatory to attacking Hill 81.    As the Battalion cleared the southern slope of Hill 79 and began to maneuver across the 1,000 yards of exposed flat terrain lying between that hill and Makabe, the entire column was taken under sniper fire from the hill.    Company G, in the lead, was forced to double time over the entire route in order to reach some cover in Makabe.   During this race for life, the Company sustained some casualties from the fire as well as 20 exhaustion cases.

To maintain the momentum of the attack, the Battalion Commander passed Company F through G at 1950 and he himself accompanied the Assault Platoon, which was pinned down as soon as it attempted to move up the slope of Hill 81.    The condition of his men, the lateness of the hour, and the intensity of the enemy fire compelled him to call off the attack and organize his Battalion into a defense perimeter near Makabe.

More satisfactory progress in the 1^st Division advance was made by the 8^th Marines.   After moving through 2/8 at 0800, 3/8 continued south to attack Ibaru Ridge following an hour-long artillery preparation and a 15-minute smoking of the target.    At 1024, the Battalion was on the ridge.    Quickly it reorganized and resumed its drive by passing Company K, 3/8 Reserve, through the initial assault elements more “for the experience rather than for any tactical necessity.”    By 1634, the entire Battalion Line was in place on the seacoast in its Zone.    The 3d Battalion, 5^th Marines, which had taken Makabe that morning, kept pace with the rapid 2,500-yard advance of 3/8 and reached the coast in its Zone at approximately the same time.    With 3/5 attached, Colonel Wallace’s Regiment took charge of the night defense of the Coastal Zone, and tied in with the 5^th  Marines and the 4^th Marines along a curving line reaching from Komesu to the boundary between the Marine Divisions.

The 4^th Marines made the major effort of the 6^th Division on 19 June, with the 22d Marines mopping up behind.    Colonel Shapley’s Battalions kept pace with the 8^th Marines most of the day, but strongly defended enemy positions in the Kiyamu-Gusuku hill mass prevented the 4^th from reaching the coast on the 19^th.    Mortar fire from defiladed emplacements behind the hill, and machine gun fire as well, increased in volume as the 1^st and 3d Battalions moved into the low ground leading from Ibaru Ridge to the Kiyamu-Gusuku plateau.    With the approach of night, the two Battalions dug in at the foot of the steep rise leading to the hilltop.    At 1845, 2/4, which had covered the open right flank of the Regiment and had taken part in the attack on the ridge, was relieved by 1/29.

Before moving into the 6^th Division Line on 20 June, the 29^th Marines began marching south from Oroku Peninsula at 0800 on the 19^th.    Its former sector was then occupied by the 6^th Reconnaissance Company.    At 1415, Colonel Whaling received orders to attack immediately in coordination with the 4^th Marines.    The Regiment jumped off from Kuwanga Ridge at 1705 with 1/29 on the left, 2/29 on the right.    Moving rapidly against light enemy resistance, the troops reached the Kiyamu-Gusuku Hill mass before dark and immediately tied in with the 4^th Marines for the night.

Unperturbed by night-long disorganized enemy infiltration attempts all along its front, the 6^th Division jumped off with four Infantry Battalions abreast—3/4, 1/4, 1/29, and 2/29 from left to right—to take the hill complex on 20 June.    Again making the Division main effort was the 4^th Marines, in whose Zone lay Hills 72 and 80, the key terrain features on the objective.    Directly in front of 1/4 Line of Departure was Hill 72, but the Battalion could not place enough men on the crest of that height at one time to maintain a solid foothold.    Japanese defenders hidden among the brush and boulders lining the narrow approach to the top frustrated all efforts to gain the hill.    Tanks attempted to cut a road to the crest from the flank of the position, but this scheme was foiled when an armored dozer was completely destroyed by a satchel charge thrown from a distance of 15 feet.   After a day of bitter fighting at hand-grenade range, the Battalion dug in for the night at the same place it had been the night before, less than 20 yards away from the enemy on the ridge above.

Steep rock cliffs, ranging from 50 to 200 feet in height and covered with heavy undergrowth, faced 3/4.    Since a frontal attack was clearly infeasible, the Battalion Commander sent a Company to the left through the 8^th Marines Zone to take the ridge by attacking up its nose on the east; this sector appeared to be the one most susceptible to attack.    Clearing out several bunkers and numerous caves to make way for Company L following in its wake, Company I mopped up the eastern slope while Company L tied in with the 8^th Marines in order to extend the Battalion’s hold on the ridge.    By late afternoon, 3/4 held strong positions on the left flank of Hill 72 and was ready to close in on that strong point.

Although it was in Regimental Reserve when the attack had begun, 2/4 was alerted to support either of the other two Assault Battalions.    At 1040, it was committed on the right of 1/4 with orders to take Hill 80.    Attacking with two Companies abreast, the Battalion reached its objective at approximately 1230, when Company G fought its way to the top against only moderate resistance.    Company E, the other assault element, was held up at the base of the hill by an enemy pocket, which the Battalion Commander decided to bypass, leaving a Company E Platoon behind to guard it.    At 1520, the two-Platoon Company passed through the right element of Company G to seize the remainder of Hill 80 from the west.    By 1645, all units of the Battalion were on the hill and digging in.    Possession of Hill 80 gave the Battalion terrain commanding the right flank of the stubbornly held Hill 72.

On the extreme right of the Division, the 29^th Marines advanced to the coast on 20 June against little opposition except for heavy fire received on the left flank of 1/29 from enfiladed positions on the reverse slope of Hill 72.    Later in the afternoon, when General Shepherd decided to envelope the Kiyamu-Gusuku sector from the left (east), he shifted the boundary of the 29th Marines to the east to include all of Ara Saki.    The Regimental Line was then tied in with the 4^th Marines for the night.    The 29^th Marines positions barred escape to the sea from the tip of the Island.

On 20 June, Psychological Warfare Detachments on board a LCI equipped with a loudspeaker broadcast surrender inducements to the many civilian and military personnel hiding in inaccessible cave refuges lining the coastal cliffs.    A feeling that further resistance was futile as well as a sense of impending doom impelled over 4,000 Island natives and some 800 soldiers to heed the message and to surrender.    These POWs were then herded through the front lines before dark to stockades in the rear.

By 20 June, 1^st Marine Division action centered about Hills 79 and 81.    While 1/5 and 2/5 concentrated their efforts in this area, extensive mopping up operations were conducted by the 7^th Marines at Kunishi “Ridge, the 8^th Marines along the coast north of Ara Saki, and 3/5 around Komesu.   These exercises added approximately 50 military and 2,000 civilian POWs to those already captured by IIIAC Forces.

After 3/5 gave Fire Support to the 7^th Division from positions on Komesu Ridge, its patrols linked up with 1/184 at 1520.     Physical contact was not maintained for the night, but both Battalions occupied high ground near Komesu and Udo and were able to cover the gap between Battalions by fire.

A brief but soaking downpour before dawn turned the roads around Makabe into knee-deep quagmires, and the tanks and M-7s supporting 2/5 were prevented from moving into positions until shortly before noon.    A more favorable situation existed in the 1/5 Zone, where tanks lumbered forward at 0730 to join the Infantry in the attack on Hill 79.   The Battalion Commander swung the axis of attack from the northwest to the southeast and assaulted the Objective with three Companies abreast.    By 1300, Company C on the right flank was 75 yards from the hillcrest, while the other two Companies A in the center and B on the left were destroying snipers and machine gun nests on the hillside with the aid of flame and gun tanks.    At 1635, Company A announced that some of its troops were on the hill, but less than two hours later it reported that heavy small arms fire had prevented it from consolidating its slight hold with the few men available; it was forced, therefore, to withdraw.    In possession of most of Hill 79, 1/5 dug in for the night, fully expecting to secure the entire Objective the next day.

At 1230, when the 2/5 tank-infantry assault on Hill 81 began, the tracked vehicles reported that road blocks in Makabe denied them passage to the hill.   An armored dozer cleared the way by 1400, and tanks moved along the road on the Corps Boundary to positions where they could fire into the right of Hill 81.   The Infantry Battalion moved to and jumped off from the northern edge of Makabe at 1520 with Companies E on the right, F on the left, and G in Reserve.   Twenty-five minutes later, Company F was pinned down in the low ground south of the hill; a smoke screen was required to cover the evacuation of casualties.   Company E, attacking from the southeast, pushed forward for about 100 yards along the eastern slope of the hill before it too was pinned down.   First Company F, and then G was ordered to pass through E and continue the attack.   Enemy machine gun and mortar fire pinned down these two Companies also.   When tanks supporting the attack ran out of ammunition at 1910 and withdrew, the Assault Companies attempted without success to garner more ground on their own.   His troops stymied, the Battalion Commander pulled them back to more favorable positions for night defense.

To the left, in the XXIV Corps Zone, only two strong enemy pockets remained at the end of 20 June.   One was centered about the caves containing the Thirty-Second Army Headquarters in Hill 89, and the other was in Medeera and west of the village on Hills 79 and 85, which together with Hill 81 in the 1^st Marine Division Zone formed the Makabe Ridge defenses.    The last courier contact between the two strong points was made on the night of 20 June, after the Commander of the 24^th Division, Lieutenant General Amamiya, urged his soldiers “to fight to the last man in their present positions.”

This exhortation fell on deaf ears for the General had few live men remaining to defend the Medeera sector at the time of proclamation.   The 1^st Marine Division had just about annihilated the 22d and 32d Regiments during its march to the coast, and the 96^th Division had destroyed the 89^th Regiment and its reinforcements when taking Yuza Dake and Aragachi.   The only troops left to General Amamiya were a motley conglomeration of artillerists, drivers, medical attendants, engineers, Boeitai, and personnel from almost every Headquarters unit of the forces that had made up the Island garrison on L-Day.   Despite the growing numbers of the enemy which surrendered and others who committed suicide, the Tenth Army still had to contend with some Japanese who fought to the last with fanatic determination.   An attack to destroy these soldiers holding the Makabe Ridge defenses was scheduled for noon of 21 June.

At 1027 that day, General Shepherd notified the Tenth Army Commander, General Geiger, that Organized Resistance had ended in the 6^th Marine Division Zone of action.   Beginning this last official day of the Okinawa campaign, the 4^th Marines enveloped troublesome Hill 72.    While 2/4 and 3/4 worked around to the south of the ridge, 1/4 held its position to support the attack by fire.    Linking up at 0930, the two Assault Battalions and Supporting Armor worked north to the objective, and then drove over its top and down the reverse slope.    By 1020, the Marines and both Flame and Gun tanks were mopping up the last vestiges of enemy resistance on the hill.    At the tip of the Island, the 29^th Marines met only light opposition during its sweep of Ara Saki; Company G, 2/22, attached to 1/29, raised the Division Colors on the southernmost point of the Island later in the day.

Both the 7^th and 8^th Marines were assigned the task of flushing out enemy holdouts in the IIIAC Zone and of accepting the surrender of an ever-increasing number of soldiers and civilians.    Hill 79 was finally taken by 1/5 at 1735; more difficult, however, was the capture of Hill 81.

Although scheduled to jump off at 0900, the attack of 2/5 was delayed until 1104 in order that tank routes could be prepared and so that the Battalion could take immediate advantage of a blistering rocket barrage on the hill objective.    The attack plan called for Company E to lead the assault on the hill, and to be followed successively by Companies F and G, which were to be fed in from the left until Hill 81 was taken.   Company E encountered only light and scattered small arms fire as it jumped off, and finally fought to and occupied its assigned objective after having destroyed two machine gun positions that had halted it on the way up.    Almost immediately, Company F began fighting its way up the slope to the hilltop, burning out and sealing caves along the route.    Shortly thereafter, Company G made its tortuous trek up the incline to join the other two at the top, all Companies received heavy fire from caves, which honeycombed the enemy position.

The effort to secure the Objective was spurred on by information received at the Battalion CP of that Hill 81 was the last organized enemy position on Okinawa; this story later proved untrue.    After having made several unsuccessful requests for reinforcements, and been ordered in turn to continue the attack with the forces at hand, at 1430 Lieutenant Colonel Benedict was relieved and ordered to report to the Regimental Commander.    He then turned over Command of the Battalion to his executive officer, Major Richard T. Washburn.    At 1500, the Commander of 3/5 reported in at the 2/5 OP and assumed Joint Command of the two Battalions; his Company L began moving to Makabe soon after to support the attack on Hill 81.

All companies advanced slowly during the afternoon, and as 2/5 reached the crest of the hill, enemy fire slackened noticeably.    At 1700, all companies reported their portion of the Objective secured; all Organized Enemy Resistance in the IIIAC Zone had ended.

In the XXIV Corps Zone, a heavy 4.2-inch mortar concentration on Hill 79 preceded the attack of 305^th Infantry elements at 1200.    The crew-served weapons organic to the Infantry Battalions supported the tank-led attack.    At 1630, following an afternoon of withering rifle and machine gun fire coming from caves and pillboxes on Makabe Ridge, the Infantry launched a final, successful surge to the top of the hill.    Before XXIV Corps Units could report the end of Organized Resistance in the Army Zone, they had to come to grips with a bitter, last-ditch Japanese defense; objectives were captured only after enemy defenders had been killed to the last man.    The soldiers first secured Mabuni and then Hill 89.    General Buckner’s doctrine of “corkscrew and blowtorch” was employed effectively by Flame Tanks and Demolition Teams burning and blasting the “Palace Guard” defending the cave entrances leading to General Ushijima’s Headquarters.    By the end of the day, Hill 89 had been secured, and its inhabitants were frantically attempting to escape a death by entombment.

After 82 days of bloody and bitter fighting, the rapid advance of the Tenth Army in the final stages of the campaign brought about irrevocable collapse of all major Japanese opposition.    General Geiger could thus announce at 1305 on 21 June that the Island of Okinawa had been secured by American forces.    The official end of the Okinawa Campaign was marked by a formal Flag-Raising Ceremony at Tenth Army Headquarters at 1000, 22 June, attended by representatives of all units in that Command.    As described by General Smith: “A large metal flagpole had already been erected at Army Headquarters. . . . The only band available was that of the 2d Marine Aircraft Wing.    Prior to playing the National Anthem,” the band played “Anchors Aweigh,” “The Marines Hymn,” and an appropriate Army tune.    Brigadier General Lawrence E. Schick, USA, Tenth Army Deputy Chief of Staff, read the official dispatch declaring the end of Organized Resistance, and General Geiger then gave the signal for the flag to be raised.

Following the official announcement on 21 June of the ending of Organized Resistance on Okinawa, Tenth Army Headquarters began receiving congratulatory messages from statesmen and Military Commanders throughout the world.    Though heartfelt and sincere, none of these Commendations to the men who had fought the Battle of Okinawa could match the simple accolade bestowed on Marines of the IIIAC by the Commander who had led them, for as General Geiger wrote:

This has been a hard campaign.  The officers and men have simply been marvelous.  They have carried on day and night, mud and battle, without a murmur and could have continued had it been necessary.  They have carried out every mission assigned by the Tenth Army and have broken through every position of the Japanese defenses which stood in their way in a minimum of time.  The Marine Corps can ever be proud of the two Divisions which fought on this island.  The cost has been high, but the time element was essential and I am sure you will be happy to know that the Marines required no urging to attack, attack, and again attack, until the Japanese were completely annihilated.  You will never know how I regret leaving the III Corps.
