Third Patrol
Her next patrol (now in the hands of Stephen H. Ambruster) began on 24 July at Pearl Harbor, ending on 19 September at Fremantle, Australia. Tambor searched for enemy shipping in the Marshall Islands. On 7 August near Wotje Atoll, she sank the converted net tender Shofaka with one torpedo which broke her in half. Tambor remained in the Marshalls until 19 August when she was ordered to patrol the southern passages to Truk. As there was time to spare before she was to take station there, she prowled through the Caroline Islands. On 21 August near Ponape, the submarine fired a spread of three torpedoes at a freighter and her escort. The first hit the target amidships and the other two aft, blowing off the stern. Shinsei Maru No. Six quickly sank. On 1 September, she fired four torpedoes at a tanker off Truk and damaged it with one hit. She was credited with two ships for 12,000 tons; this was reduced to 5,800 tons postwar.
