June 1945 - The Americans bore over 49,000 casualties including 12,520 killed. General Buckner was killed in action on June 18, just days before the battle ended. Japanese losses were even greater—about 110,000 Japanese soldiers lost their lives. It's estimated between 40,000 and 150,000 Okinawa citizens were also killed.
Terrible. Followed by Nagasaki and Hiroshima in August. What madness.
