Iwo Jima According to the USMC and which has been hammered through every Marine's head since WWII, Tarawa is the bloodiest battle of the island hopping battles. Iwo Jima is commonly mistaken as the bloodiest as it had a much higher profile because of the famous "staged" photo. Iwo had the most deaths, 26,800 total (20,000 Japanese, 6,800 US)but the battle took 35 days, 766 total deaths per day, (194 Marines per day). Tarawa had 5,700 total deaths (4,700 Japanese, 1,000 US) in 3 days, 1,900 total deaths per day, (333 Marines per day). I think it boils down to how you quantify "bloodiest". The Marines must feel that 333 Marine deaths per day is bloodier than 194 per day. I would tend to agree.
