有声读物: Final Campaign: Marines in the Victory on Okinawa

The three-month-long battle of Okinawa covered a 700-mile arc from Formosa to Kyushu and involved a million combatants--Americans, Japanese, British, and native Okinawans. With a magnitude that rivaled the Normandy invasion the previous June, the battle of Okinawa was the biggest and costliest single operation of the Pacific War. For each of its 82 days of combat, the battle would claim an average of 3,000 lives from the antagonists and the unfortunate non-combatants.” (Joseph H. Alexander)
