16 Jul 1944

Philippines
  • West of Luzon in the Philippines, submarine USS Piranha made contact with the 26-ship Japanese Convoy TAMA-21C southbound from Takao in Taiwan to Manila in the Philippines. Piranha torpedoed and sank the 6,000-ton troop ship Seattle Maru and then withstood a depth charge attack of over 100 charges. Piranha’s “Mickey Finns” wolfpack partners, Guardfish and Thresher, closed in on the convoy and launched a continuous attack that lasted into the following day and covered 100 miles of ocean. Thresher sank 2,800-ton transport ship Shozen Maru and 4,916-ton merchant ship Sainei Maru. Thresher also claimed sinking destroyer IJN Kusagaki but she was unscathed. Guardfish sank the 6,000-ton transport ship Mantai Maru and the 5,200-ton transport ship Jinzan Maru and later the 3,000-ton merchant ship Hiyama Maru. A total of 42 torpedoes were fired by the three submarines with 28 hits claimed. ww2dbase [Piranha | Thresher | Guardfish | South China Sea | CPC, HM]
