Lost at Sea
Pompano departed Midway 20 August, 1943, intending to patrol the Japanese coast off Hokaido and Honshu. She was never heard from again, although Japanese records indicate two cargo ships were sunk in her area in September 1943. The records make no mention of any anti-submarine attacks in the area during this period. Since the Japanese coast in her patrol area was known to be heavily mined, the most probable cause for her loss was striking a mine.
