The Battle of Midway, fought from June 3 — 7, 1942, seventy-seven years ago this week, was a major American victory in the Pacific theater in World War II. Only six months after Japan’s attack on Pearl Harbor, Midway was a turning point in the naval war in the Pacific. Key to the victory was the American breaking of the Japanese naval code. Thanks to the code breakers, what had been intended to be another Japanese surprise attack became a well-laid trap by the US Navy. Here is a 15-minute tactical overview of the battle. Well worth watching.
