USS Grouper
Quote:
09:22 I battle surfaced to bring my deck gun to bear on the Coastal Tanker. Fired 17 rounds for 15 hits and sent this ship down (SUNK). SJ radar reported the Troop ship 5,200 yds dead ahead so I rang up flank speed to get in range for another deck gun action. Fired a total of 30 rounds for 28 hits (SUNK). After securing the deck gun I set course for Midway Island.

Don't know the time it took to fire the rounds or the approximate tonnage of the ships he sunk, but he sunk one with 15 hits and another with 28.
