BATTLE OF OKINAWA

BATTLE OF OKINAWA


Toward the end of World War II, Japan's Pacific army retreated to Okinawa, a 454-square-mile island south of Japan's major islands. The Battle of Okinawa that took place there was the largest land, sea and air battle in history and the last major battle of World War II. Referred to by Okinawans as a "typhoon of steel," the battle lasted from March to June 1945 and pitted 278,000 American troops against 83,000 Japanese. The fighting was particularly fierce because the island was the last obstacle on the way to reaching Japan itself. The Battle of Okinawa left at least 200,000 Japanese dead, including civilians. The Japanese government has counted 240,609 dead. [Source: Doug Struck, Washington Post, July 20, 2000]

The Battle of Okinawa was one of the bloodiest and most inhuman conflicts of World War II and the last great amphibious campaign of the war. Describing as a "vast field of mud, lead, decay, and maggots," it left more than 100,000 Okinawan civilians dead, with over 72,000 American and 100,000 Japanese casualties. The Allies lost 36 warships and landing craft and 763 aircraft. More than 12,500 Allied servicemen were killed. Only 7,400 Japanese troops survived the conflict to become prisoners of war. The Japanese commander-in-chief on Okinawa, Lieutenant-General Ushijima Mitsuru, committed suicide on 22 June. [Source: BBC]

Okinawa is situated 550 kilometers (340 miles) south of the Japanese mainland. America sent 170,000 troops and 1,213 warships. British forces also took part. The island was defended by nearly 100,000 Japanese troops. Lt-Gen Ushijima relied on mass kamikaze attacks as his main line of defense against the initial assault. More than 2,000 attacks were launched during the conflict.

The BBC reported: The conflict began on 1 April, when America's newly-formed 10th Army, led by Lieutenant-General Simon Bolivar Buckner, landed on Okinawa's western coast. By 21 April most of the island had been taken by US troops but a stalemate developed in the south around Okinawa's capital city, Naha. The Japanese were able to secure a strong defensive position in the rugged, cave-riddled terrain and it took several weeks to finally win the battle. [Source: BBC, June 21, 1945]

Alastair Himmer wrote in the Jakarta Post: The battle claimed the lives of more than 100,000 Okinawan civilians and 80,000 Japanese troops, whose grim resistance only ended after Lieutenant General Mitsuru Ushijima, the senior officer on the island, committed ritual suicide on a cliff. Almost every family in Okinawa suffered at least one casualty as the US bombardment — by land, sea and air — reduced the normally lush, green landscape to a scorched wasteland. More than 12,000 American troops also perished during the worst bloodshed of the Pacific War, in what many feared at the time was a foretaste of the battle they would have to fight for the Japanese mainland. That battle never came, thanks in part to the atomic bombing of Hiroshima and Nagasaki. Okinawa was the only part of Japan in which fighting took place in World War II.” [Source: Alastair Himmer, The Jakarta Post, June 22, 2015]

Fighting on Okinawa


Marine sprinting

As was the case on Iwo Jima, the Japanese army did not concentrate its forces at the Allied landing points but hide in the interior of the island in caves and bunkers. As the Americans moved inland they were attacked with showers of mortars, bombs and gunfire from dozens of well-hidden bunkers positioned along side the most logical paths of advance.

The Americans were able to use artillery against the Japanese as they moved to different ambush points. Yamamoto, the 23-year-old soldier, said, "The bombs were like rain. The shells came in and men simply vanished. The land, and the trees, and the men simply disappeared, as though they were extinguished."

At Okinawa Japanese soldiers emerged from caves in banzai charges with explosives strapped to their bodies. They also popped out of “spider holes” and shot the enemy from behind as they did on Iwo Jima. Of the 51 people in Yamamoto's unit, 43 were killed in a single day. He personally observed a man strap 20 pounds of explosives on his back and throw himself in the path of a tank.

One American soldier, who landed on the beaches of Okinawa less than three weeks after his 18th birthday, told the Washington Post, "You didn't expect to get killed. You expected the other guy to get killed." He found the landing easy but got caught in crossfire after moving inland. "At nighttime, we would strap a box of grenades, and haul them up the hill" to the men at the front. "I remember seeing Marines stacked three deep, wrapped in ponchos, their blood dried, legs contorted. It was really demoralizing. At the end we were fighting for the United States, sure, but we really fighting for each other. We were fighting just to stay alive, and we would do anything to stay alive."

After being wounded by shrapnel that went clear through his calf, the American soldier said, "A corpsman put morphine into me, so I was feeling pretty good. I remember I was just worried about all my souvenirs. But the corpsman ran everybody else off and I never got them back."

Pre-Invasion and Preliminary Bombardment of Okinawa

Bombing of Okinawa began in October 1944. Following a massive bombardment from battleships positioned offshore, American troops came ashore in D-Day-style landing crafts on April 1, 1945. Yoshinaka Yamamoto, a 23-year-old soldier at time of the battle, told the Washington Post, "For the first time in my life, I saw ships coming out of ships. They would get to shallow water, and start to move on their own. I had never thought of that idea. I was stunned."

Tokyo sent a message to its commanders to order troops to "fight to the last moment believing in final victory." Bombing of Okinawa began in October 1944. Battle of Okinawa survivor Haruko Oshiro said: “During that time there was construction project under way at le-Jima, the most important airport to the east... However this huge airport project became the main target for U.S. soldiers. On October 10, 1944, 90 percent of Naha City was destroyed due to an air raid. Day by day bombardment by warships and bombing by air hit hard in Okinawa as the war became more severe.[Source: Haruko Oshiro in Okinawa, Global Geopolitics, translated from Japanese into English by Makoto Higasa. /globalgeopolitics.net <+>]


Initial attack


Ted Tsukiyama wrote: The April 1st invasion was preceded by 7 days of "softening up" artillery fire of 13,000 rounds by U.S. Navy guns and 3,095 sorties by carrier planes from Task Force 58 at the proposed landing sites at Hagushi and Chatan beaches. On the morning of April 1st, navy ships rained a prelanding bombardment of 44,825 shells, 33,000 rockets and 22,500 mortar shells plus napalm attacks by carrier planes on the invasion beaches. This was the incendiary prelude to the Battle of Okinawa which Masahide Ota was to aptly and vividly describe in his book as "the typhoon of steel and bombs!"

Ted Tsukiyama wrote: “In the early pre-dawn twilight of April 1, 1945, Sgt. Takejiro Higa of the 314th Language Detachment of the U.S. 96th Infantry Division peered out at the familiar Okinawan coastline from the deck of an invasion ship with a sinking heart. Conflicting emotions churned within him: "I have a duty and responsibility as an American soldier. But why must I invade the home of my ancestors?" He stood on deck facing the approaching island with tears streaming down his cheeks.

“As the U.S. forces prepared to make land, little did Higa realize that he was to witness and participate in "Operation Iceberg," the bloodiest and most bitterly fought battle of the Pacific War where almost 240,000 American, Japanese and Okinawan lives were lost and the island of Okinawa left devastated and ravished. <<<


Landing on the beach of Ibeya


“The American attacking force consisted of 183,000 troops of the U.S. Tenth Army and Marine Divisions commanded by General Simon Bolivar Buckner, supported by Navy and Air Force fire and bombardment. Okinawa was defended by 77,000 troops of the Japanese 32nd Army commanded by Gen. Mitsuru Ushijima, assisted by Lt.Gen Isamu Cho and Col. Hiromichi Yahara, and augmented by conscripted 20,000 "Boeitai" (Okinawa Home Guard) as labor and service troops and 750 middle school boys organized into the "Tekketsu Kinnotai" (Blood and Iron Corps). <<<

“For "Operation Iceberg," Pacific Commander Admiral Nimitz had assembled and launched the greatest amphibious invasion force of the Pacific War, as the horizon of the offshore sea was almost obliterated with hundreds and hundreds of ships moving toward the invasion beaches. <<<

“As the pre-H Hour bombardment lifted, an 8-mile long line of amphibious assault and landing craft moved shoreward onto the Hagushi and Chatan beachheads landing 60,000 assault troops, surprisingly without any enemy fire or resistance. <<<

Japanese Defense of Okinawa

Ted Tsukiyama wrote: “Twenty kilometers to the south from the top of Shuri Castle, General Ushijima and his staff calmly peered through binoculars, witnessing the devastating bombardment followed by thousands of American troops landing on the beaches unmolested, laughing and bemused that the enemy had wasted all that valuable ammunition on undefended ground. But this was all in accordance with the Japanese strategy to conserve its troop strength concentrated in the southern end of Okinawa, by allowing an initial enemy landing but to strenuously defend against the invading Americans at the strongly fortified Naha-Shuri-Yonabaru defense line.

Gun fortification

Col. Yahara used the term the jikyusen, war of attrition, to describe the overall Japanese military strategy and philosophy for Japanese defense at Okinawa. He wrote; "Japan was frantically preparing for a final decisive battle on the home islands, leaving Okinawa to face a totally hopeless situation. From the beginning I had insisted that our proper strategy was to hold the enemy as long as possible, drain off his troops and supplies, and thus contribute our utmost to the final decisive battle for Japan proper." (Hiromichi Yahara, The Battle for Okinawa, p. 49). <<<

Tsukiyama wrote: “Translated into real terms, this dark outlook was to render the entire Japanese forces, the total land and resources of Okinawa and all of its residents, to become totally expendable in Japan's defense of Okinawa. The scales of military strategy were balanced out when soon after the landing, a captured Japanese document was referred to XXIV Corps Headquarters G-2 Nisei personnel, Dan Nakatsu, Kenichi Ota and Herbert Nishita for translation. This was a battle plan prepared by Japan's military genius, Col. Yahara, Deputy Chief of Staff, for General Ushijima, which not only predicted the exact date of the April 1 invasion but the American objectives of Kadena and Yontan (Yomitan) air bases, the expected American battle routes, and the Japanese defense positions, strategy and tactics. Early in the battle, U.S. commanders thus learned how well organized and heavily defended Okinawa would be in the bloody days to come. <<<

Pierson of the 38th Japanese Order of Battle Team recalls going ashore on the second assault wave, landing with Takejiro Higa and advancing inland together through the rural Okinawan countryside. Upon making the unopposed landing on D-Day April 1st, American Army and Marine forces quickly advanced inland cutting through Koza, Shimabuku and Momobaru to reach Nakagusuku Bay on the Pacific Ocean side in two days and effectively cutting the island and its Japanese defenders in half.

Capture of Ie Shima

Ted Tsukiyama wrote: “The island of Ie Shima (or "Ie Jima") lying 4 miles west of Motobu peninsula held one of the largest airfields in the Asia-Pacific region and was vitally needed to provide air support to the assault on Okinawa. On April 16, aerial and naval artillery, rocket and mortar bombardment saturated Ie Shima to soften up the beachhead landing of the U.S. 77th Division. Ie Shima was defended by an estimated 7,000 soldiers of the 44th Independent Mixed Brigade commanded by Major Tadashi Ikawa (the "Ikawa Unit") entrenched in heavily and intricately fortified pillboxes, gun emplacements, tunnels and caves centered around Ie town, Bloody Ridge and Iegusugu hill ("The Pinnacle").

“The advance and encirclement of the Ie defenses by the 305th, 306th and 307th Regiments was stubbornly resisted by the Japanese defenders for six days. On April 17, the renowned war correspondent Ernie Pyle was killed by a hidden machine gun on the outskirts of Ie town. <<<

“On April 21 Ie Shima was declared secure after 4,706 Japanese were killed and 149 captured with 1,500 Okinawan civilians dead while at a cost of 172 Americans killed, 902 wounded and 46 missing. Maj. Gen Andrew Bruce declared "the last three days of fighting were the bitterest I have ever witnessed."

Japanese Air and Sea Counterattacks

Ted Tsukiyama wrote: “On April 6, 400 Japanese attack planes flew out from Kyushu to launch "kamikaze" attacks on the American invasion forces and hundreds of American warships, troopships, supply vessels and landing craft offshore from the beachheads, inflicting heavy damage.

“That night remnants of the Japanese fleet including the mighty battleship "Yamato" steamed out of Kyushu to meet the American flotilla off Okinawa, but on April 7th planes from Task Force 58 intercepted the Japanese armada in the East China Sea, directing bombing and torpedo attacks against the enemy fleet, sinking the pride of the Japanese Navy the "Yamato," cruiser "Yahagi" and three destroyers and destroying the last remnants of the Japanese Navy for good. Japanese suicide attacks against American troops and ships continued through the month of April, inflicting heavy damage and casualties but losing up to 1,100 Japanese planes. <<<

“For the first two days the XXIV Corps advanced easily southward through light enemy resistance until April 5 when it encountered a hail of effective fire from entrenched Japanese positions along the Machinato-Nishibaru-Ouki line and were forced to withdraw. On April 6-9, the 7th and 96th Infantry Divisions took Cactus Ridge (Mashiki), Red Hill (Minami-Uebaru), and Triangulation Hill and Tomb Hill (Ouki) after fierce resistance by Japanese defenders, until encountering the defensive stronghold of Kakazu Ridge. On April 9 the 96th Division opened the first of several attacks against the Kakazu line, all of which were repulsed by savage Japanese defenses during the next four days, particularly from artillery and mortar fire fr9m well concealed firing positions. <<<

“About this time a major breakthrough occurred when a map was found on a dead Japanese artillery officer in a forward observers' position which was immediately sent to XXIV Corps Headquarters G-2. There, Nisei MIS linguists of the 306th and 307th HQ Intelligence Detachments led by Dan Nakatsu and George Takabayashi translated the map to reveal the positions, ranges and bearings of all Japanese artillery and mortar emplacements on Okinawa, a tremendous and priceless find! The Japanese map was overlayed on to U.S. artillery maps and distributed to all American attacking forces. The theretofore hidden Japanese gun emplacements were no longer a mystery, and were subsequently neutralized and destroyed by pinpointed American artillery, mortar and napalm fire. <<<

Mentality of the American Soldiers Fighting in Okinawa

E. B. Sledge wrote in "With the Old Breed: At Peleliu and Okinawa,"The weather was cool and there was the wonderful smell of pines, which reminded me of home. It was such a beautiful island; you really could not believe that there was going to be a battle there...A column of men approached us on the other side of the road – They were the army infantry from the 106th Regiment, 27th Infantry Division that we were relieving. Their tragic expressions revealed where they had been. They were dead beat, dirty and grisly, hollow-eyed and tight-faced… As they filed past us, one tall, lanky fellow caught my eye and said in a weary voice, "It's hell up there, Marine." Nervous about what was ahead and a bit irritated that he might think I was a boot, I said with some impatience, "Yeah, I know. I was at Peleliu." He looked at me blankly and moved on.

“I found it more difficult to go back each time we squared away our gear to move forward into the zone of terror… And it wasn’t just dread of death or pain, because most men felt somehow they wouldn’t be killed… Each time we went up, I felt the sickening dread of fear itself and the revulsion at the ghastly scenes of pain and suffering among comrades that a survivor must witness. The increasing dread of going back into action obsessed me. It became the subject of the most tortuous and persistent of all the ghastly war nightmares that have haunted me for many, many years. The dream is always the same, going back up to the lines during the bloody month of May on Okinawa. \+\

“On 8 May Nazi Germany surrendered unconditionally. We were told the momentous news, but considering our own peril and misery, no one cared much. We were resigned only to the fact that the Japanese would fight to total extinction on Okinawa, as they had elsewhere, and that Japan would have to be invaded with the same gruesome prospects. Nazi Germany might as well have been on the moon.” \+\

Cave Warfare and Intense Fighting During the Southern Okinawa Campaign

According to “Okinawa: The Last Battle”: "The main zone of defense was planned as a series of concentric positions adapted to the contours of the area. Caves, emplacements, blockhouses, and pillboxes were built into the hills and escarpments, connected by elaborate underground tunnels and skillfully camouflaged; many of the burial tombs were fortified. The Japanese took full advantage of the terrain to organize defensive areas and strong points that were mutually supporting, and they fortified the reverse as well as the forward slopes of hills. Artillery and mortars were emplaced in the caves and thoroughly integrated into the general scheme of defensive fires." [Source: “Okinawa: The Last Battle,” by Roy E. Appleman, James M. Burns, Russell A. Gugeler, John Stevens, p. 95]

Navy Intelligence Officer Frank B. Gibney described the fierce Japanese defense as follows: "For the next two weeks the war settled down to the most bitter, ruthless kind of hand-to-hand fighting, as GIs and marines desperately tried to claw their way up heavily defended rocky escarpments. The advancing troops were exposed not merely to constant mortar, machine gun, and rifle fire, but they took a pounding from General Wada's artillery. It was the worst fighting of the Pacific war, its sustained intensity surpassing even the brutal combat of Tarawa, Peleliu, and Iwo Jima." [Source: Yahara, “The Battle for Okinawa,” p.33-34]

Preceded by intense artillery bombardment, Japanese troops infiltrated the American defenses along the Machinato-Kakazu-Ouki line on the night of April 12 and advanced northward as far as Ginowan.

But after bitter fighting the U.S. attackers were stopped cold at Urasoe-Mura, Tombstone Nishibaru-Kakazu and Skyline (Ouki) defensive strongholds suffering 720 casualties. The drive toward Shuri was stopped. On April 20, the 165th Infantry of the 27th Division threw itself against the Gusukuma defenses but was repulsed by well dug-in enemy defense and fire around the strong point of "Item Pocket," holding off the American attackers for 7 days. The 27th Division went on to overcome the twin Pinnacle defenses near Nakama by April 23 after suffering heavy casualties. The Outer Shuri Line stretching from Ouki, Tanabaru, Nishibaru, Kakazu and Urasoe-Mura Escarpment was savagely defended by the enemy entrenched in caves, tunnels and tombs prepared with criss-crossed fields of artillery, mortar and automatic fire over all approaches. <<<

“Inflicting great losses and casualties, the Japanese yielded no ground and fought to death. But after Americans had won bitterly earned break-throughs at key points along the First Shuri Line, Japanese defenders then withdrew from the Outer Shuri Line during the night of April 24 under cover of fog and heavy artillery fire to take up the defense of Shuri and Naha. Japanese defenders had fallen back to a defense line stretching from Jichaku through Nakama, Maeda, Kochi to Conical Hill (Yonabaru). On April 26, Gen. Buckner ordered the 1st and 6th Marine Divisions and 77th Infantry Division to join the attacking American forces against the Shuri Line and there followed over 4 weeks of the severest fighting of the Pacific War until Shuri was finally taken. <<<

Japanese troops on landing barges attempted to encircle and land behind American lines but were soon annihilated. Kamikazes attacked U.S. Naval shipping. On May 5 the 24th Division pierced American lines at Kochi and penetrated as far north as Tanabaru, but after 3 days of frantic and bitter fighting the Japanese invaders were annihilated by withering artillery, mortar and machine gun fire on all fronts, suffering devastating losses of over 5,000 lives and crippling the Japanese 32nd Army.

Afterwards, Gen. Ushijima called in Col. Yahara and said:"Col. Yahara, as you predicted, this offensive has been a total failure. Your judgment was correct. You must have been frustrated from the start of this battle because I did not use your talents and skill wisely. Now I am determined to stop this offensive. Meaningless suicide is not what I want we will fight to the southernmost hill, to the last square inch of land, and to the last man.

The 1st and 6th Marine, 7th, 77th and 96th Divisions attacked with tanks and infantry, cave-by-cave, hill-by-hill meeting fierce resistance at every sector. <<<

“Artillery, mortar and flame-throwers were directed at pillboxes and caves, sending the defenders into retreat and hiding, then advancing troops up to the mouth of caves and pillpoxes, destroying them with demolition or napalm-gasoline fire and entombing the Japanese defenders within.

The First Marines advancing past Itoman faced murderous defensive fire from defenders on Yuza Peak and Kunishi Ridge, and were pinned down for days suffering heavy losses until supporting tank, air, naval and ground artillery fire systematically destroyed the last enemy resistance. <<<

“Yuza and Kunishi could be taken by the U.S. Marines only after 5 days of bitterest fighting and suffering some of the highest casualties of the Okinawa campaign. Around this time the entrenched Japanese were not only bombarded by ceaseless U.S. naval guns but were showered with surrender leaflets and daily loudspeaker broadcasts in fluent Japanese from offshore craft urging:"Japanese soldiers. You fought well and proudly for the cause of Japan, but now the issue of victory or defeat has been decided. To continue the battle is meaningless. We will guarantee your lives. Please come down to the beach and swim out to us." But these messages were ignored, and only a few swam out to offshore American ships. <<<

On June 17, General Buckner sent a message to General Ushijima which read: "The forces under your command have fought bravely and well. Your infantry tactics have merited the respect of your opponents in the battle for Okinawa. Like myself you are an infantry general, long schooled and experienced in infantry warfare. You must surely realize the pitiful plight of your defense forces. You know that no reinforcements can reach you. I believe, therefore, that you understand as clearly as I, that the destruction of all Japanese resistance on the island is merely a matter of days. It will entail the necessity of my destroying the vast majority of your remaining troops."


Attack on bloody ridge

Col. Yahara wrote that "General Buckner's proposal for us to surrender was, of course, an affront to Japanese tradition. General Ushijima's only reaction was to smile broadly and say, 'The enemy has made me an expert on infantry warfare.'" But in his innermost thoughts Col. Yahara pondered over the "Japanese tradition" of committing suicide rather than to surrender: "In Japan, from the thirteenth century until the Meiji Restoration of the mid-nineteenth century, there are many examples where every soldier was killed in defense of the castle. In some cases only the lord of the castle committed suicide, while the soldiers (samurai) lived. In the early years of Meiji, Tokugawa supporters readily surrendered to the new Imperial Army. Since the Meiji Restoration, through the Sino-Japanese War, the Russo-Japanese War, and the China Incident of 1931, Japan had never lost a war. We also had never waged a war in which large forces were isolated from mainland support. Thus, not to be taken prisoner became a fixed principle---part of our military education.

“Since the middle of the Greater East Asia War, most Japanese garrisons in the Pacific islands adhered to this supreme Japanese principle: 'Never surrender to the enemy.' Officers and men usually committed suicide, as a last resort to avoid the ultimate 'shame of capture. Our 32nd Army was now faced with this situation. Must one hundred thousand soldiers die because of tradition? From this point on it was but a battle to kill the remaining Japanese soldiers for nothing. We could cause the enemy little damage; they could walk freely on the field of battle. The war of attrition was over, and we would simply be asking the enemy to use this formidable power to kill us all." [Source: Yahara, p. 137-138]

Horror, Caranage and Death in Okinawa

E. B. Sledge wrote in "With the Old Breed: At Peleliu and Okinawa,"By twos and threes, the Company K men forming the front line eased onto a barren, muddy, shell-torn ridge named Half Moon Hill and into the foxholes of the company we were relieving….It was the most ghastly corner of hell I had ever witnessed…The place was choked with the putrefaction of death, decay and destruction. In a shallow defilade to our right…lay about twenty dead Marines, each on a stretcher and covered to his ankles with a poncho… but as I looked out I saw that other Marine dead couldn’t be tended properly. [Source: Eugene Sledge's "With the Old Breed: At Peleliu and Okinawa," pbs.org/thewar \+\]

“Every crater was half full of water, and many of them held a Marine corpse. The bodies lay pathetically just as they had been killed, half submerged in muck and water, rusting weapons still in hand. Everywhere lay Japanese corpses, killed in the fighting. Swarms of big flies hovered above them…For several feet around every corpse, maggots crawled about in the muck… I believed we had been flung into hell's own cesspool. \+\

“If a Marine slipped and slid down the back slope of the muddy ridge, he was apt to reach the bottom vomiting. I saw more than one man … stand up horror stricken as he watched in disbelief while fat maggots tumbled out of his muddy dungaree pockets, cartridge belt, legging lacings and the like…. We didn't talk about such things. They were too horrible and obscene even for hardened veterans. The conditions taxed the toughest I knew almost to the point of screaming. Nor do authors normally write about such vileness…it is too preposterous to think that men could actually live and fight for days under such terrible conditions and not be driven insane. But I saw much of it there on Okinawa and to me the war was insanity. \+\

“We thought the Japanese would never surrender. Many refused to believe it. Sitting in stunned silence, we remembered our dead. So many dead. So many maimed. So many bright futures consigned to the ashes of the past. So many dreams lost in the madness that had engulfed us. Except for a few widely scattered shouts of joy, the survivors of the abyss sat hollow-eyed and silent, trying to comprehend a world without war.” \+\


Kamikaze crashes near USS Ticonderoga


Kamikaze Attacks at Okinawa and the Sinking of the Yamato

An estimated 1,360 Japanese kamikaze pilots died in attacks against Allied ships during the Battle of Okinawa. About half left from Chirancho in Kyushu. Others departed from other bases in southern Japan and in Taiwan. They sunk several ships that resulted in the death of 5,000 sailors.

At 10:00am on May 10, 1945, a kamikaze pilot in a Japanese Zero crashed into the deck of the U.S. aircraft carrier Bunker Hill destroying 30 bomb-laden American planes. Thirty seconds later another suicide bomber with 550 pounds of explosives tore into the vessels amidships, blasting a 49-foot hole and setting off a fire that blazed for six hours and took the lives of 353 of the ships 3,000-member crew.

The giant battleship The Yamato was ordered to attack the Allied amphibious force in Okinawa in what essentially was a suicide mission. The Yamato was ordered to beach itself and to act as an unsinkable gun emplacement and continue to fight until destroyed. and steer itself into the middle of an invading American armada and blow itself up. On April 7, 1945, en route to Okinawa, the Yamato was attacked by 280 aircraft and sunk in the South China Sea off Kyushu. Only 260 members of 2,800-member crew survived.

The Yamato sinking was made into a number of popular Japanese films. The Yamato and Musashi (sunk in the Philippine Sea in October, 1944) were the largest battleships ever commissioned. They displaced 78,387 tons, were 863 feet long and were armed with 18-inch guns that fired 3,200 pound projectiles. The pride of the Japanese fleet, they were described as “the world's greatest battleship” by Encyclopedia Britanica.



Battle of Okinawa Finally Ends

On June 21, 1945 the Battle of Okinawa was finally over. The BBC reported: “Okinawa has finally fallen to the Americans after a long and bloody battle. The island will now provide the Americans with an invaluable air and naval base from which to launch a sustained and forceful attack on the mainland. It is estimated more than 90,000 Japanese troops were killed in the 82-day conflict. America also suffered heavy losses - at this stage 6,990 servicemen have been reported killed or missing and 25,598 wounded. [Source: BBC, June 21, 1945]

In a statement issued today US Fleet Admiral Chester W Nimitz said: "After 82 days of fighting the battle of Okinawa has been won. "Organised resistance ceased on June 21. Enemy garrisons in two small pockets are being mopped up."The Japanese fought a desperate battle until the bitter end with many hiding out in caves on the southern-most tip of the island. As the US forces closed in many threw themselves off 150ft (45.7m)cliffs or waded into the sea to drown rather than be taken prisoner. More than 4,000 Japanese have so far been captured.

Ted Tsukiyama wrote: “By June 17 the 10th Army forces penetrated and held all major positions along the last Japanese Gushichan-Itoman defensive line. The key high ground of Hill 153 near Madeera (Maehira) was taken by 7th Division troops from remnants of the disintegrating Japanese 32 Army now down to their last ammunition and supplies. [Source: Ted Tsukiyama, "The Battle of Okinawa", Hawaii Nisei Project, University of Hawaii, nisei.hawaii.edu <<<]

The Japanese counterattack to recapture Hill 153 ordered by Ushijima was decimated on June 18. After that organized Japanese resistance dissolved into disorganized mobs fighting desperately, determined to take every attacking American to death with them. They were faithfully following General Ushijima's last order which read:"The battlefield is now in such chaos that all communications have ceased. It is impossible for me to command you. Every man in these fortifications will follow his superior officer's order and fight to the end for the sake of the motherland. This is my final order. Farewell." [Source: Yahara, “The Battle for Okinawa,” p. 134]

Thousands of Japanese were holed up in caves around Madeera and Makabe defending fanatically, forcing the U.S. 5th Marines to fight on until June 21 to wipe out the survivors and to secure this last pocket of resistance.

Legacy and Casualties of the Battle of Okinawa

The 83-day struggle for Okinawa ended on June 22, 1945, positioning American forces just 350 miles south of Kyushu. the southernmost of Japan's main islands. Some soldiers didn't surrender until August 29, 1945, two weeks after Japan's surrender ended the war. Okinawa was taken in less than three months but the cost were so high that plans for similar attacks on the mainland were shelved in favor of atomic weapons.

In the battle of Okinawa 34 ships were sunk and 368 damaged. When the war was over only one of Japan's nine battleships was still afloat. "In less than four years, this great war machine fell from glory to oblivion," wrote naval historian Masanori Ito. The underground Japanese naval headquarters on Okinawa wasn't discovered until three weeks after the battle was over. The underground corridors contained the bodies of 4,000 naval officers and men, nearly all of whom had committed ritual suicide.

Like Iwo Jima, Okinawa was bloody battle of attrition. Some 140,000 people died fighting, including 14,006 American troops, 82 other Allied personnel, 75,219 Japanese troops and 148,289 Okinawans (most of them citizens). About 37,500 Americans were injured. There were more American causalities at Iwo Jima and Okinawa than there were in the previous three years of the war.

On Okinawa 7,400 Japanese soldiers surrendered, a sign that the Japanese die-instead-of-surrender had its limits and defeat was imminent. Both the Japanese and American commanders in the battle died. Lieut. General Simon Bolivar Buckner was killed by a stray bullet and Lieut. General Mitsuru Ushijima committed suicide by plunging a sword into his abdomen.

Half of the civilians on Okinawa were either killed or wounded during the battle. Nearly a third (150,000 civilians) died. Most residents today know of at least one relative who died. The Okinawan people had been deceived by Japan, who told them the Americans were being lured into a trap and would be easily defeated. Naha was reduced to rubble and many smaller towns and villages were destroyed.
