2. Downfall’s Expected Casualties Were Horrific
The resources committed to Operation Olympic dwarfed those of the D-Day landings in France. They included 42 aircraft carriers, 24 battleships, 400 destroyers and destroyer escorts, tactical air support from the Fifth, Seventh, and Thirteenth Air Forces, and 14 divisions for the initial landing. Casualties, would likely have been horrific. Depending on the degree of Japanese civilian resistance (Japanese authorities were training even women and children to fight the invaders with spears and pointy sticks), worst case scenarios envisioned over a million Allied casualties, with Japanese casualties numbering in the tens of millions. Such casualties would have made the conquest of Japan history’s bloodiest campaign, ever.
