The Battle of Iwo Jima (19 February -- 26 March 1945), or Operation Detachment, was a major battle in which the United States Armed Forces fought for and captured the island of Iwo Jima from the Japanese Empire.
The American invasion had the goal of capturing the entire island, including its three airfields (including South Field and Central Field), to provide a staging area for attacks on the Japanese main islands. This five-week battle comprised some of the fiercest and bloodiest fighting of the War in the Pacific of World War II.
After the heavy losses incurred in the battle, the strategic value of the island became controversial. It was useless to the Army as a staging base and useless to the Navy as a fleet base.
