USS Snapper (SS-185) - Fifth, Sixth and Seventh War Patrols

Fifth, Sixth and Seventh War Patrols

Although both the fifth and sixth war patrols were also unproductive, during the seventh, conducted in the vicinity of Guam, Snapper sank her initial victim of the war. According to her war diary, she sighted two vessels moored in the extreme northeast corner of Apra Harbor, Guam, and decided to patrol submerged off the harbor until they departed. Seven days later, on 27 August, she headed to the north of the harbor, firing three torpedoes at the first target and one at the second. As she quickly departed the vicinity, Snapper observed one hit on the first target, sinking the passenger-cargo ship Tokai Maru, stern first.

On 2 September, Snapper closed a convoy of five cargo ships and two escorts. The primary targets, the cargo ships, zigged away; and, when the port escort came into view "head on," the submarine fired a "down-the-throat" shot at the escort, Japanese frigate Mutsure, that blew the enemy's bow completely off and enveloped her in flames as she sank. The submarine quickly cleared the locality as the other escort commenced a depth charge attack. On 6 September, Snapper intercepted another convoy and fired three torpedoes; but all were misses. On 17 September, she terminated her seventh patrol at Pearl Harbor.
