Which battle is noted for having the highest casualty rate in Marine Corps history?

The Battle of Iwo Jima is known for having the highest casualty rate in Marine Corps history, which is a significant aspect of the Marines' legacy during World War II. This battle, fought from February 19 to March 26, 1945, resulted in approximately 26,000 U.S. Marine casualties, with around 6,800 killed in action. The intense and brutal fighting over this strategically important island, which served as a base for fighter aircraft to escort bombers on missions to the Japanese home islands, emphasized the cost of such an operation in terms of human life.

The significance of this battle is not only in the sheer number of casualties but also in the fierce resistance encountered from the Japanese defenders, who fought tenaciously from well-prepared positions. The extraordinary valor displayed by the Marines during the battle, as well as the iconic flag-raising on Mount Suribachi, has further cemented Iwo Jima's place in Marine Corps history. Understanding the high casualty rates experienced there highlights the sacrifice and commitment of the Marines in accomplishing their mission despite overwhelming odds.
