The worst battle of the Pacific War, Iwo Jima, which turned the tide of World War II. In June 1944, the coalition forces successfully landed in Normandy, which was the turning point of the coalition's victory. The US military was able to turn its combat strength to the Pacific Ocean, landed on Saipan in June and Guam in July, and General MacArthur set foot on Philippine soil for the second time. Japan stubbornly defended Iwo Jima, with a military strength of about 21000 men. The US military dispatched a total of 75000 men from three divisions, 495 ships, and other destroyers and aircraft carriers to attack Iwo Jima with all its strength. This documentary was shot by the photography team of the third US military Command, and it is the only historical material left in the world that most faithfully records the second World War and the Battle of Iwo Jima.
