　　  In the Battle of Attu during the Pacific War, on May 30th 1943, the Japanese army launched a final banzai charge in search of food at a point known as “Slaughter Bay”. Some Japanese soldiers took American gun turrets or food. In the end, cornered by the Americans, the Japanese soldiers on Attu killed or committed suicide. American soldiers performed autopsies on the bodies of the Japanese soldiers scattered across Attu Island on June 1st.

　　The Battle of Attu ended after the last Japanese soldier's banzai charge broke through the American lines, and most of the Japanese defenders were killed in brutal hand-to-hand combat. On May 29th, the Japanese army led the remaining soldiers in a banzai charge against the American army with no hope of rescue. The surprise attack broke through the American front line. The shocked American rear guard immediately engaged in hand-to-hand combat with the Japanese soldiers. The fighting continued until almost all of the Japanese soldiers had been annihilated. In the 19 days of fighting, 549 soldiers of the American 7th Infantry Division were killed and more than 1,200 were wounded. The Japanese army suffered 2,351 deaths and 28 were taken prisoner.

　　On May 30, of the approximately 1,400 Japanese who had been in the valley until the previous day, May 29, only 28 survived. The rest had either been killed in action or had committed suicide by placing a grenade against their chest. When the American troops came across the Japanese hospital, all of the wounded had been killed by the doctors. The Battle of Attu was ranked as the second deadliest battle (in proportion to the number of troops engaged) for the US military in the Pacific War, second only to Iwo Jima.
