The Japanese command defended Iwo Jima until the last soldier and the last round, and the Americans themselves suffered significant losses during the offensive. The battle for Iwo Jima is a story of the heroism of soldiers of both nations.

During the battle, 21703 Japanese soldiers from a total of 22800 men were killed.
