Battle of Okinawa
The end of World War II
Easter Sunday, April 1, 1945, my 1st Marine Division invaded the island of Okinawa. It was the last Pacific island infected with Japanese soldiers before invading mainland Japan. 
Okinawa was the largest 
amphibious assault in the Pacific War of World War II. The 82-day-long battle 
lasted from early April until mid-June 1945. After a long campaign of island 
hopping, the Allies were approaching Japan, and planned to use Okinawa, a large 
island only 340 miles away from mainland Japan, as a base for air 
operations on the planned invasion of Japanese mainland (coded Operation 
Downfall . 
Four divisions of the U.S. 10th Army (the 7th, 27th, 77th, and 
96th) and two Marine Divisions (the 1st and 6th fought on the island. Their 
invasion was supported by naval, amphibious, and tactical air forces.
 
The battle has been referred to as the "typhoon of steel" in English, and 
tetsu no ame ("rain of steel") or tetsu no bofu ("violent wind of 
steel") in Japanese. The nicknames refer to the ferocity of the fighting, the 
intensity of kamikaze attacks from the Japanese defenders, and to the 
sheer numbers of Allied ships and armored vehicles that assaulted the island. 
The battle resulted in the highest number of casualties in the Pacific Theater 
during World War II. Based on Okinawan government sources, mainland Japan lost 
77,166 soldiers, who were either killed or committed suicide, and the Allies 
suffered 14,009 deaths (with an estimated total of more than 65,000 casualties 
of all kinds). Simultaneously, 42,000-150,000 local civilians were killed or 
committed suicide, a significant proportion of the local population. The atomic 
bombings of Hiroshima and Nagasaki caused Japan to surrender less than two 
months after the end of the fighting on Okinawa.
Although Allied land forces were entirely composed of 
U.S. units, the British Pacific Fleet (BPF; known to the U.S. Navy as Task Force 
57) provided about ? of Allied naval air power (450 planes). It comprised a 
force which included 50 warships of which 17 were aircraft carriers, but while 
the British armored flight decks meant that fewer planes could be carried in a 
single aircraft carrier, they were more resistant to kamikaze strikes. 
Although all the aircraft carriers were provided by Britain, the carrier group 
was a combined British Commonwealth fleet with British, Canadian, New Zealand 
and Australian ships and personnel. Their mission was to neutralize Japanese 
airfields in the Sakishima Islands and provide air cover against Japanese 
kamikaze attacks. Most of the air-to-air fighters and the small dive 
bombers and strike aircraft were U.S. Navy carrier-based airplanes. The U.S. 
Navy sustained greater casualties in this operation than in any other battle of 
the war.
Japanese
The Japanese land campaign (mainly defensive) was 
conducted by the 67,000-strong (77,000 according to some sources) regular 32nd 
Army and some 9,000 Imperial Japanese Navy (IJN) troops at Oroku naval base 
(only a few hundred of whom had been trained and equipped for ground combat), 
supported by 39,000 drafted local Ryukyuan people (including 24,000 hastily 
drafted rear militia called Boeitai and 15,000 non-uniformed laborers). 
In addition, 1,500 middle school senior boys organized into front-line-service 
"Iron and Blood Volunteer Units", while 600 Himeyuri Students were organized 
into a nursing unit. The Japanese had used kamikaze tactics since the 
Battle of Leyte Gulf, but for the first time, they became a major part of the 
defense. Between the American landing on 1 April and 25 May, seven major 
kamikaze attacks were attempted, involving more than 1,500 planes.
 
The 32nd Army initially consisted of the 9th, 24th, and 62nd Divisions, and 
the 44th Independent Mixed Brigade. The 9th Division was moved to Taiwan prior 
to the invasion, resulting in shuffling of Japanese defensive plans. Primary 
resistance was to be led in the south by Lt. General Mitsuru Ushijima, his chief 
of staff, Lieutenant General Isamu Cho and his chief of operations, Colonel 
Hiromichi Yahara. Yahara advocated a defensive strategy, whilst Cho advocated an 
offensive one. In the north, Colonel Takehido Udo was in command. The IJN troops 
were led by Rear Admiral Minoru Ota. They expected the Americans to land 6?10 
divisions against the Japanese garrison of two and a half divisions; the staff 
calculated that superior quality and numbers of weapons gave each U.S. division 
five or six times the firepower of a Japanese division; to this would be added 
the Americans' abundant naval and air firepower.
Naval battle
The United States Navy's Task Force 58, deployed to the east of Okinawa with 
a picket group of from 6 to 8 destroyers, kept 13 carriers (7 CV and 6 CVL) on 
duty from 23 March to 27 April and a smaller number thereafter. Until 27 April, 
from 14 to 18 converted carriers (CVE's) were in the area at all times, and 
until 20 April British Task Force 57, with 4 large and 6 escort carriers, 
remained off the Sakishima Islands to protect the southern flank. The protracted 
length of the campaign under stressful conditions forced Admiral Chester W. 
Nimitz to take the unprecedented step of relieving the principal naval 
commanders to rest and recuperate. Following the practice of changing the fleet 
designation with the change of commanders, U.S. naval forces began the campaign 
as the U.S. 5th Fleet under Adm. Raymond Spruance, but ended it as the 3rd Fleet 
under Adm. William Halsey.
 
Japanese air opposition had been relatively light during the first few days 
after the landings. However, on 6 April the expected air reaction began with an 
attack by 400 planes from Kyushu. Periodic heavy air attacks continued through 
April. During the period 26 March-30 April, 20 American ships were sunk and 157 
damaged by enemy action. For their part, the Japanese had lost up to 30 April 
more than 1,100 planes in the battle to Allied naval forces alone. Between 6 
April and 22 June, the Japanese flew 1,465 kamikaze aircraft in 
large-scale attacks from Kyushu, 185 individual kamikaze sorties from 
Kyushu, and 250 individual kamikaze sorties from Formosa. When U.S. 
intelligence estimated 89 planes on Formosa, the Japanese had approximately 700, 
dismantled or well camouflaged and dispersed into scattered villages and towns; 
the U.S. Fifth Air Force disputed Navy claims of kamikaze coming from 
Formosa. The ships lost were smaller vessels, particularly the destroyers of the 
radar pickets, as well as destroyer escorts and landing ships. While no major 
Allied warships were lost, several fleet carriers were severely damaged. 
Land-based motorboats were also used in the Japanese suicide attacks.
Operation 
Ten-Go
Operation Ten-Go (Ten-go 
sakusen) was the attempted attack by a strike force of ten Japanese surface 
vessels, led by the super battleship Yamato and commanded by Admiral 
Seiichi Ito. This small task force had been ordered to fight through enemy naval 
forces, then beach themselves and fight from shore using their guns as coastal 
artillery and crewmen as naval infantry. The Ten-Go force was spotted by 
submarines shortly after it left the Japanese home waters, and was intercepted 
by U.S. carrier aircraft. Under attack from more than 300 aircraft over a 
two-hour span, the world's largest battleship sank on 7 April 1945 after a 
one-sided battle, long before she could reach Okinawa. U.S. torpedo bombers were 
instructed to aim for only one side to prevent effective counter flooding by the 
battleship's crew, and hitting preferably the bow or stern, where armor was 
believed to be the thinnest. Of Yamato's screening force, the light cruiser 
Yahagi a four of the eight destroyers were also sunk. In all, the 
Imperial Japanese Navy lost some 3,700 sailors, including Admiral Ito, at the 
relatively low cost of just 10 U.S. aircraft and 12 airmen.
British Pacific 
Fleet
The British Pacific Fleet, taking part as Task Force 57, was assigned the 
task of neutralizing the Japanese airfields in the Sakishima Islands, which it 
did successfully from 26 March-10 April. On 10 April, its attention was shifted 
to airfields on northern Formosa. The force withdrew to San Pedro Bay on 23 
April. On 1 May, the British Pacific Fleet returned to action, subduing the 
airfields as before, this time with naval bombardment as well as aircraft. 
Several kamikaze attacks caused significant damage, but since the British 
used armored flight decks on their aircraft carriers, they only experienced a 
brief interruption to their force's objective.
Land battle
The land battle took place over about 81 days beginning on 1 April 1945. The 
first Americans ashore were soldiers of the 77th Infantry Division, who landed 
in the Kerama Islands (Kerama Retto), 15 mi (24 km) west of Okinawa on 26 March. 
Subsidiary landings followed, and the Kerama group was secured over the next 
five days. In these preliminary operations, the 77th Infantry Division suffered 
27 dead and 81 wounded, while Japanese dead and captured numbered over 650. The 
operation provided a protected anchorage for the fleet and eliminated the threat 
from suicide boats.
 
On 31 March, Marines of the Fleet Marine Force Amphibious Reconnaissance 
Battalion landed without opposition on Keise Shima, four islets just 8 mi 
(13 km) west of the Okinawan capital of Naha. 
155 mm (6.1 in) "Long Tom"s went ashore on the islets to cover operations on 
Okinawa.
Northern Okinawa
The main landing was made by XXIV Corps and III Amphibious Corps on the 
Hagushi beaches on the western coast of Okinawa on L-Day, 1 April, which 
was both Easter Sunday and April Fools' Day in 1945. The 2nd Marine Division 
conducted a demonstration off the Minatoga beaches on the southeastern coast to 
confuse the Japanese about American intentions and delay movement of reserves 
from there.
 
The 10th Army swept across the south-central part of the island with relative 
ease by World War II standards, capturing the Kadena and the Yomitan airbases 
within hours of the landing. In light of the weak opposition, General Buckner 
decided to proceed immediately with Phase II of his plan the seizure of northern 
Okinawa. The 6th Marine Division headed up the Ishikawa Isthmus and by 7 April, 
had sealed off the Motobu 
Peninsula.
 
Six days later on 13 April, the 2nd Battalion, 22nd Marine Regiment reached 
Hedo Point (Hedo-misaki) at the northernmost tip of the island. By this point, 
the bulk of the Japanese forces in the north (codenamed Udo Force) was 
cornered on the Motobu Peninsula. Here, the terrain was mountainous and wooded, 
with the Japanese defenses concentrated on Yae-Take; a twisted mass of rocky 
ridges and ravines on the center of the peninsula. There was heavy fighting 
before the Marines finally cleared Yae-Take on 18 April.
 
Meanwhile, the 77th Infantry Division assaulted Ie Island (Ie Shima)?a small 
island off the western end of the peninsula?on 16 April. In addition to 
conventional hazards, the 77th Infantry Division encountered kamikaze 
attacks, and even local women armed with spears. There was heavy fighting before 
Ie was declared secured on 21 April and became another air base for operations 
against Japan.
Southern Okinawa
While the 6th Marine Division cleared northern Okinawa, the U.S. Army 96th 
Infantry division and 7th Infantry Division wheeled south across the narrow 
waist of Okinawa. The 96th Infantry Division began to encounter fierce 
resistance in west-central Okinawa from Japanese troops holding fortified 
positions east of Highway No. 1 and about 5 mi (8.0 km) northwest of Shuri, from 
what came to be known as Cactus Ridge. 
The 7th Infantry Division encountered 
similarly fierce Japanese opposition from a rocky pinnacle located about 
1,000 yd (910 m) southwest of Arakachi (later dubbed "The Pinnacle"). By the 
night of 8 April, U.S. troops had cleared these and several other strongly 
fortified positions. They suffered over 1,500 battle casualties in the process, 
while killing or capturing about 4,500 Japanese, yet the battle had only just 
begun, for it was now realized they were merely outposts guarding the Shuri 
Line.
 
The next American objective was Kakazu Ridge, two hills with a connecting 
saddle that formed part of Shuri's outer defenses. The Japanese had prepared 
their positions well and fought tenaciously. The Japanese soldiers hid in 
fortified caves. The U.S. forces often lost men before clearing the Japanese out 
from each cave or other hiding place. The Japanese sent Okinawans at gunpoint 
out to acquire water and supplies for them, which led to civilian casualties. 
The American advance was inexorable but resulted in a high number of casualties 
on both sides.
 
As the American assault against Kakazu Ridge stalled, Gen. Ushijima, 
influenced by Gen. Cho, decided to take the offensive. On the evening of 12 
April, the 32nd Army attacked U.S. positions across the entire front. The 
Japanese attack was heavy, sustained, and well organized. After fierce close 
combat the attackers retreated, only to repeat their offensive the following 
night. A final assault on 14 April was again repulsed. The effort led 32nd 
Army's staff to conclude that the Americans were vulnerable to night 
infiltration tactics, but that their superior firepower made any offensive 
Japanese troop concentrations extremely dangerous, and they reverted to their 
defensive strategy.
 
The 27th Infantry Division?which had landed on 9 April?took over on the 
right, along the west coast of Okinawa. General John R. Hodge now had three 
divisions in the line, with the 96th in the middle, and the 7th on the east, 
with each division holding a front of only about 1.5 mi (2.4 km). Hodge launched 
a new offensive of 19 April with a barrage of 324 guns, the largest ever in the 
Pacific Ocean Theater. Battleships, cruisers, and destroyers joined the 
bombardment, which was followed by 650 Navy and Marine planes attacking the 
enemy positions with napalm, rockets, bombs, and machine guns. The Japanese 
defenses were sited on reverse slopes, where the defenders waited out the 
artillery barrage and aerial attack in relative safety, emerging from the caves 
to rain mortar rounds and grenades upon the Americans advancing up the forward 
slope.
A tank assault to achieve breakthrough by outflanking Kakazu Ridge, failed to 
link up with its infantry support attempting to cross the ridge and failed with 
the loss of 22 tanks. 
Although flame tanks cleared many cave defenses, there was 
no breakthrough, and the XXIV Corps lost 720 men KIA, WIA and MIA. The losses 
might have been greater, except for the fact that the Japanese had practically 
all of their infantry reserves tied up farther south, held there by another 
feint off the Minatoga beaches by the 2nd Marine Division that coincided with 
the attack.
 
At the end of April, after the Army forces had pushed through the Machinato 
defensive line,[22] the 1st Marine 
Division relieved the 27th Infantry Division, and the 77th Infantry Division 
relieved the 7th. When the 6th Marine Division arrived, III Amphibious Corps 
took over the right flank and 10th Army assumed control of the battle.
 
On 4 May, the 32nd Army launched another counteroffensive. This time, 
Ushijima attempted to make amphibious assaults on the coasts behind American 
lines. To support his offensive, the Japanese artillery moved into the open. By 
doing so, they were able to fire 13,000 rounds in support but an effective U.S. 
counter-battery fire destroyed dozens of Japanese artillery pieces. The attack 
failed.
 
Buckner launched another American attack on 11 May. Ten days of fierce 
fighting followed. On 13 May, troops of the 96th Infantry Division and 763rd 
Tank Battalion captured Conical Hill. Rising 476 ft (145 m) above the Yonabaru 
coastal plain, this feature was the eastern anchor of the main Japanese defenses 
and was defended by about 1,000 Japanese. Meanwhile, on the opposite coast, the 
1st and 6th Marine Divisions fought for "Sugar Loaf Hill". The capture of these 
two key positions exposed the Japanese around Shuri on both sides. Buckner hoped 
to envelop Shuri and trap the main Japanese defending force.
 
By the end of May, monsoon rains which turned contested hills and roads into 
a morass exacerbated both the tactical and medical situations. The ground 
advance began to resemble a World War I battlefield as troops became mired in 
mud and flooded roads greatly inhibited evacuation of wounded to the rear. 
Troops lived on a field sodden by rain, part garbage dump and part graveyard. 
Unburied Japanese and American bodies decayed, sank in the mud, and became part 
of a noxious stew. Anyone sliding down the greasy slopes could easily find their 
pockets full of maggots at the end of the journey.
 
On 29 May, Maj. Gen. Pedro del Valle, commanding the 1st Marine 
Division, ordered Company A, 1st Battalion, 5th Marines to capture Shuri Castle. 
Seizure of the castle represented both strategic and psychological blows for the 
Japanese and was a milestone in the campaign. Del Valle was awarded a 
Distinguished Service Medal for his leadership in the fight and the subsequent 
occupation and reorganization of Okinawa. Shuri Castle had been shelled by the 
battleship USS Mississippiifor three days before this advance. Due to 
this, the 32nd Army withdrew to the south and thus the marines had an easy task 
of securing Shuri Castle. The castle, however, was outside the 1st Marine 
Division's assigned zone and only frantic efforts by the commander and staff of 
the 77th Infantry Division prevented an American air strike and artillery 
bombardment which would have resulted in many casualties due to friendly 
fire.
 
The Japanese retreat, although harassed by artillery fire, was conducted 
with great skill at night and aided by the monsoon storms. The 32nd Army was 
able to move nearly 30,000 men into its last defense line on the Kiyan 
Peninsula, which ultimately led to the greatest slaughter on Okinawa in the 
latter stages of the battle, including the deaths of thousands of civilians. In 
addition, there were 9,000 IJN troops supported by 1,100 militia, with 
approximately 4,000 holed up at the underground headquarters on the hillside 
overlooking the Okinawa Naval Base in the Oroku Peninsula, east of the airfield. 
On June 4, elements of the 6th Marine Division launched an amphibious assault on 
the peninsula. The 4,000 Japanese sailors? including Admiral Minoru Ota - all 
committed suicide within the hand-built tunnels of the underground Naval 
headquarters on 13 June. By 17 June, the remnants of Ushijima's shattered 32nd 
Army were pushed into a small pocket in the far south of the island to the 
southeast of Itoman. On 18 June, Gen. Buckner was killed by enemy artillery fire 
while monitoring the forward progress of his troops. Buckner was replaced by Roy 
Geiger. Upon assuming command, Geiger became the only U.S. Marine to command a 
numbered army of the U.S. Army in combat; he was relieved five days later by 
Joseph Stilwell.
 
The last remnants of Japanese resistance fell on 21 June, although some 
Japanese continued hiding, including the future governor of Okinawa Prefecture, 
Masahide Ota. Ushijima and Cho committed suicide by seppukuuin their 
command headquarters on Hill 89 in the closing hours of the battle. Col. Yahara 
had asked Ushijima for permission to commit suicide, but the general refused his 
request, saying: "If you die there will be no one left who knows the truth about 
the battle of Okinawa. Bear the temporary shame but endure it. This is an order 
from your army Commander." Yahara was the most senior officer to have survived 
the battle on the island, and he later authored a book titled The Battle for 
Okinawa.
Casualties
Okinawa was the bloodiest battle of the Pacific War. The most complete tally 
of deaths during the Battle are at the Cornerstone of Peace monument at the 
Okinawa Prefecture Peace Park identifies the names of each individual who died 
at Okinawa due to World War II. As of 2010, the monument lists 240,931 names, 
including 149,193 Okinawan civilians, 77,166 Imperial Japanese soldiers, 14,009 
U.S. soldiers, and smaller numbers of people from South Korea (365), the UK 
(82), North Korea (82) and Taiwan (34). The numbers correspond to recorded 
deaths during the Battle of Okinawa from the time of the U.S. landings in the 
Kerama Islands on 26 March 1945 to the signing of the Japanese surrender on 2 
September 1945, in addition to all Okinawan casualties in the Pacific War in the 
fifteen years from the Manchurian Incident, along with those who died in Okinawa 
from war-related events in the year before the battle and the year after the 
surrender. 234,183 names were inscribed by the time of unveiling and new names 
are added each year. Thirty thousand of the Okinawan civilians killed had been 
drafted or impressed by the Japanese army and are often counted as combat 
deaths.
Military losses
U.S. losses
U.S. manpower losses amounted to over 82,000 casualties, including non-battle 
casualties (psychiatric, injuries, illnesses) of whom over 12,500 were killed or 
missing. Battle deaths were 4,907 Navy, 4,675 Army, and 2,938 Marine Corps 
personnel. Several thousand servicemen who died indirectly (from wounds and 
other causes) at a later date are not included in the total. One of the most 
famous U.S. casualties was the war correspondent Ernie Pyle, who was killed by 
Japanese sniper fire on Ie Island (Ie Shima, a small island just off of 
northwestern Okinawa). Lt. Gen. Buckner's decision to attack the Japanese 
defenses head-on, although extremely costly in U.S. lives, was ultimately 
successful. Just four days from the closing of the campaign, Buckner was killed 
by Japanese artillery fire, which blew lethal slivers of coral into his body, 
while inspecting his troops at the front line. He was the highest-ranking U.S. 
officer to be killed by enemy fire during the war. The day after Buckner was 
killed, Brig. Gen. Claudius Miller Easley was killed by machine gun fire.
 
Aircraft losses over the three-month period were 768 U.S. planes, including 
those bombing the Kyushu airfields launching kamikazes. Combat losses 
were 458, and the other 310 were operational accidents. On land, the U.S. forces 
lost at least 225 tanks and many LVTs. At sea, 368 Allied ships?including 120 
amphibious craft?were damaged while another 28, including 15 amphibious ships and 
12 destroyers, were sunk during the Okinawa campaign. The U.S. Navy's dead 
exceeded its wounded with 4,907 killed and 4,874 wounded, primarily from 
kamikaze attacks.
 
The U.S. personnel casualties included thousands of cases of mental 
breakdown. According to the account of the battle presented in Marine Corps 
Gazette.
More mental health issues arose from the Battle of Okinawa than any other 
battle in the Pacific during World War II. The constant bombardment from 
artillery and mortars coupled with the high casualty rates led to a great deal 
of men coming down with combat fatigue. Additionally the rains caused mud that 
prevented tanks from moving and tracks from pulling out the dead, forcing 
Marines (who pride themselves on burying their dead in a proper and honorable 
manner) to leave their comrades where they lay. This, coupled with thousands of 
bodies both friend and foe littering the entire island, created a scent you 
could nearly taste. Morale was 
dangerously low by the month of May and the state of discipline on a moral basis 
had a new low barometer for acceptable behavior. The ruthless atrocities by the 
Japanese throughout the war had already brought on an altered behavior (deemed 
so by traditional standards) by many Americans resulting in the desecration of 
Japanese remains, but the Japanese tactic of using the Okinawan people as human 
shields brought about a new aspect of terror and torment to the psychological 
capacity of the Americans.
Japanese losses
The U.S. military estimates that 110,071 Japanese soldiers were killed during 
the battle. This total includes an unknown number of impressed Okinawan 
civilians who were killed during the battle.
 
7,401 soldiers surrendered or were captured during the battle. Additional 
Japanese were captured or surrendered over the next few months raising the total 
to 16,346. This was the first battle in the Pacific War in which thousands of 
Japanese soldiers surrendered or were captured. Many of the prisoners were 
native Okinawans who had been pressed into service shortly before the battle and 
were less imbued with the Imperial Japanese Army's no-surrender doctrine. When 
the American forces occupied the island, many Japanese soldiers put on Okinawan 
clothing to avoid capture and some Okinawans would come to the Americans' aid by 
offering to detect the mainland Japanese in hiding.
 
The Japanese lost 16 combat vessels, including the super battleship 
Yamato. Japanese aircraft losses were 7,830, including 2,655 to 
operational accidents. Navy and Marine Corps fighters downed 3,047, while 
shipboard anti-aircraft fire felled 409, and the B-29s destroyed 558 on the 
ground. The Allies destroyed 27 Japanese tanks and 743 artillery pieces 
(including mortars, anti-tank and anti-aircraft guns), some of them eliminated 
by the naval and air bombardments but most of them knocked-out by American 
counter-battery fire.
Civilian losses, suicides and atrocities
Some islands that saw major battles, such as Iwo Jima, were uninhabited or 
previously evacuated. Okinawa, by contrast, had a large indigenous civilian 
population; U.S. Army records from the planning phase of the operation make the 
assumption that Okinawa was home to about 300,000 civilians. According to 
various estimates, between one tenth and one third of them died during the 
battle, or between 42,000 and 150,000 dead. Okinawa Prefecture's estimate is 
over 100,000 losses, while the official U.S. Army count for the 82-day campaign 
is a total of 142,058 civilian casualties, including those killed by artillery 
fire, air attacks and those who had been pressed into service by the Imperial 
Japanese Army. During the battle, U.S. soldiers found it difficult to 
distinguish civilians from soldiers. It became routine for U.S. soldiers to 
shoot at Okinawan houses, as one infantryman wrote, "There was some return fire 
from a few of the houses, but the others were probably occupied by civilians 
and we didn't care. It was a terrible thing not to distinguish between the enemy 
and women and children. Americans always had great compassion, especially for 
children. Now we fired indiscriminately." Since many 
Okinawan residents fled to caves where they subsequently were entombed, the 
precise number of civilian casualties will probably never be known.
 
In its history of the war, the Okinawa Prefectural Peace Memorial Museum 
presents Okinawa as being caught between in the fighting between the United 
States and the Empire of Japan. During the 1945 battle, the Japanese Army showed 
indifference to Okinawans' safety, and its soldiers even used civilians as human 
shields against the Americans, or just outright murdered them. Japanese military 
confiscated food from the Okinawans and executed those who hid it, leading to a 
mass starvation among the population, and forced civilians out of their 
shelters. Japanese soldiers also killed about 1,000 people who spoke in the 
Okinawan language in order to suppress spying. The museum writes that "some were 
blown apart by [artillery] shells, some finding themselves in a hopeless 
situation were driven to suicide, some died of starvation, some succumbed to 
malaria, while others fell victim to the retreating Japanese troops."
 
With the impending victory of American troops, civilians often committed mass 
suicide, urged on by the Japanese soldiers who told locals that victorious 
American soldiers would go on a rampage of killing and raping. Ryukyu 
Shimpo  one of the two major Okinawan newspapers, wrote in 2007: "There are 
many Okinawans who have testified that the Japanese Army directed them to commit 
suicide. There are also people who have testified that they were handed grenades 
by Japanese soldiers" to blow themselves up. Thousands of the civilians, having 
been induced by Japanese propaganda to believe that U.S. soldiers were 
barbarians committing horrible atrocities, killed their families and themselves 
to avoid capture. Some of them threw themselves and their family members from 
the southern cliffs where the Peace Museum now resides. However, having been 
told by the Japanese military that they would suffer terribly at the hands of 
the arriving Americans if they allowed themselves to be taken alive, Okinawans 
"were often surprised at the comparatively humane treatment they received from 
the American enemy." Islands of Discontent: Okinawan Responses to Japanese 
and American Power by Mark Selden, notes that the Americans "did not pursue 
a policy of torture, rape, and murder of civilians as Japanese military 
officials had warned." U.S. Military Intelligence Corps combat translators such 
as Teruto Tsubota managed to convince many civilians not to kill themselves. 
Survivors of the mass suicides blamed also the indoctrination of their education 
system of the time, when the Okinawans were taught to become "more Japanese than 
the Japanese," and expected to prove it.
 
Witnesses and historians reported that soldiers on both sides had raped 
Okinawan women during the battle. Rape by Japanese troops "became common" in 
June, after it became clear that the Japanese Army had been defeated. Marine 
Corps officials in Okinawa and Washington have said that they knew of no rapes 
by American servicemen in Okinawa at the end of the war. The New York 
Times, however, reported on the 1945 alleged incident in the village of 
Katsuyama, where civilians said they had formed a vigilante group to ambush and 
kill three black American soldiers whom they claimed would frequently rape the 
local girls there.
