　　　During the Battle of Iwo Jima in the Pacific War, Japanese soldiers were killed and fell by the American army on Iwo Jima. Both the Japanese and American armies continued to fight fiercely, suffering heavy casualties. The Battle of Iwo Jima, which the American army invaded on February 19th 1945, broke out. The Japanese army was completely wiped out from caves and other strongholds by relentless close-quarters attacks. The Battle of Iwo Jima was fought in a landscape of molten sulfur and steam, defensive terrain, continuous underground tunnels, treacherous waves, and hundreds of hidden fighting positions housing fanatical, suicidal Japanese soldiers.

　　　In the 36 days of fighting on Iwo Jima, the amphibious troops killed a staggering 22,000 Japanese soldiers and sailors. The US Marine Corps and Navy assault troops suffered 24,053 casualties, of which 6,140 were killed. It was also the only battle in which the US suffered more casualties than the Japanese. Nearly 700 Americans per square kilometer died. On an area the size of a football pitch, an average of more than one US soldier and five Japanese soldiers died, and five US soldiers were injured.

　　The Battle of Iwo Jima ended on March 26th 1945, and the American occupation of Iwo Jima increased the range, payload and survivability of large bombers. The B-29s based in the Mariana Islands increased the monthly tonnage of high explosives dropped on Japan by 11 times in March alone. On April 7, 80 P-51 Mustangs took off from Iwo Jima to escort the B-29s attacking the Nakajima Aircraft Factory in Tokyo. The US Air Force made good use of Iwo Jima as an emergency landing site, and by the end of the Pacific War, a total of 2,251 B-29s had been forced to land on Iwo Jima, corresponding to 24,761 aircrew.
