The entire force landed on Iwo Jima on D-Day with the first assault wave led by the Fourth Marine Division. The 133rd suffered severe casualties during the fight for Iwo Jima, where it distinguished itself in both frontline combat and construction. The 133rd had 370 casualties, more than 40 percent of the 875 men who landed, the highest percentage of casualties as part of a single battle in Seabee history.
