April 1, 1944
(USN) USS Tunny (SS-282) patrolled off Alet Island, made radar contact with a Japanese ship dead ahead. Heading in for a flank attack, she sighted a Momo-class destroyer 1,000 yards astern of her chosen target. Tunny fired three torpedoes from 960 yards and noted a hit in the forward hold of the Japanese cargo ship before diving to 300 feet to avoid the attention of the destroyer. Minutes later, a series of nine depth charges tumbled down in search of the submarine, but exploded at too shallow a depth toachieve their purpose. As Tunny started up to take a look, she was jolted by a deep-set depth charge which caught her at 260' but caused only minor damage. Before midnight, the destroyer gave up the search, and the submarine surfaced and set her course for the Namonuito group to the north.
