When was the Battle of Iwo Jima Fought?

Fought from February 19 to March 26, 1945, the Battle of Iwo Jima was one of the most significant battles of World War II. For just over a month, the United States (US) went against Imperial Japan on the volcanic island of Iwo Jima. Both sides suffered immense casualties: 7,000 American Marines were killed, while 20,000 were wounded, and 21,000 Japanese defenders fought to the death.

The United States’ prime objective in the Battle of Iwo Jima was to secure airfields that allowed damaged B-29 American bombers to successfully land and launch attacks on the mainland of Japan.


Furthermore, those airfields provided emergency landing sites if a damaged aircraft was coming into land.


While the United States sought to have a secretive strategy, the Japanese knew their plan.


They began to heavily fortify the island with bunkers, tunnels, and artillery to defend it when the time came.


Japanese troops built 11 miles of connected tunnels, bunkers, and 1,500 caves to stay safe from heavy naval shelling.


Moreover, General Kuribayashi ordered his men to wait until U.S. Marines moved inland before opening a trap of crossfire.


Iwo Jima’s capture by the US Marines shifted the tide in World War II.


With their victory, the US now had a critical base for air operations against Japan, which they held from February 19, 1945, until the island was returned to Japan on June 26, 1968.


Moreover, the battle became an influence to drop the atomic bombs a few months later.


Overall, 6,000 American troops died, with total United States casualties reaching 26,000, while 18,000 to 21,000 Japanese were killed during the defense.
