Japan officially surrendered on September 2, 1945. But on October 18, 1945 — six weeks after the surrender — a Japanese pilot named Lieutenant Second Class Kazuo Odashima took off from Kanoya airfield in a Mitsubishi Ki-51 aircraft on what he claimed was a "sacrifice mission." He flew toward the Allied occupation fleet in Kure Harbor and crashed into the sea. Was it a true kamikaze attack, delayed intelligence, a glitch in communication, or a deliberate protest? No Allied ships were damaged. The incident was classified for 50 years. Odashima's final letter, found in his locker after the crash, read: "I will go because I must go, not because I want to kill. The war is over but I don't know how to stop being a soldier."
