At Peleliu the 1st Marine Division suffered 6,526 battle casualties and the 81st Division another 3,275, totaling between them 1,792 fatalities. The Wildcats also lost 2,500 men, at least temporarily, to sickness, nonbattle injuries, and combat fatigue. Almost 15 percent of the Americans who participated became casualties. Infantrymen accounted for 79 percent of the killed, wounded, or missing. The Japanese lost about 11,000 soldiers killed, plus a handful taken prisoner. They succeeded in inflicting a one-to-one casualty ratio on the Americans, a disquieting harbinger for future battles.
