USS Thresher (SS-200) - First and Second Patrols

First and Second Patrols

Litchfield promptly set off to join American light forces departing from the harbor, leaving Thresher alone to conduct her first real war patrol. However, the destroyer was ordered back to escort; radio contact was established, and a rendezvous arranged, with Thresher. At the pre-appointed time, Thresher poked up her periscope to have a look, and noticed a destroyer—similar to Litchfield—approaching bows-on. Instead of a warm reception from friends, she got a hot reception from the destroyer's forward gunners, who opened fire on her as soon as her black conning tower broke the surface. Thresher immediately went deep to avoid. She again tried to enter the harbor on 8 December, but was driven off by depth-bombs from a patrol plane, before Thornton (AVD-11) finally arrived to provide safe conduct for the boat at midday.

Departing Pearl Harbor on 30 December 1941, Thresher headed for the Marshall and Mariana Islands. Reconnoitering Majuro, Arno, and Mili atolls from 9 to 13 January 1942, she shifted to waters off Japanese-held Guam in the early morning darkness of 4 February. A little before daybreak, a small freighter was sighted 7 miles (11 km) north of Agana Harbor and Thresher closed for the attack. She loosed a three-torpedo spread, holing the ship and sending it down by the bow and dead in the water. Thresher then fired another spread of torpedoes, but all missed. Upon returning to the scene one-half-hour later the ship was gone and Thresher thought she had scored a kill; postwar accounting did not substantiate it.

While en route home to Pearl Harbor on 24 February, an overzealous Navy plane attacked Thresher but did no damage and the sub safely returned to port on 26 February.
