Pearl Harbor Attack, 7 December 1941. Chart of Pearl Harbor recovered from a Japanese midget submarine captured after the attack. The chart shows various courses around Ford Island and gives ship locations that do not necessarily correspond to actual 7 December ship positions. Since it presumably came from the midget submarine HA-19, which was unsuccessful in its attempts to enter the harbor, these details probably represent expected ship locations and intended maneuvers by the submarine. 80-G-413507
