hack to search in vain for what she assumed was a Japanese submarine that had attacked her. The following days were uneventful, bringing Brill sightings of sailing junks, Allied aircraft, and some Japanese planes. On 1 March 1945, she made contact on three small Japanese patrol boats in shallow water, probably trying to trap an unsuspecting Allied submarine. Commander Dodge avoided the trap and continued to search for a worthwhile target. On 5 March 1945, he found one. While Brill patrolled submerged, Dodge sighted a large Japanese tanker escorted by two destroyers and a plane. Brill immediately attempted to move into position to attack the tanker, but gave up the effort an hour later when she could not close the range with it. On 6 March 1945, Brill joined the submarine in a coordinated patrol in the Tonkin Gulf. On 8 March 1945, Japanese planes forced them both to submerge and attacked them with depth charges, but neither submarine sustained damage. On 15 March 1945, while providing lifeguard services for American bombers attacking Hainan Island, Brill maneuvered to avoid another torpedo fired at her, presumably by a Japanese submarine. She again was unable to make contact with the attacking Japanese submarine. On 21 March 1945, Brill rendezvoused with the submarine to bring aboard an Australian Army officer and a native Malayan guide for a special mission on Sakala Island. Brill patrolled down the coast of Japanese-occupied French Indochina and arrived off Sakala Island on 25 March 1945. That night, the Australian commando and his partner went ashore. They returned to Brill an hour later with five Indonesians. When this entire party had embarked, Brill set course for Fremantle, Western Australia, where she completed her patrol with her arrival on 30 March 1945. Second war patrol Following a normal two-week refit and a short training period, Brill departed Fremantle on 27 April 1945 to begin her second war patrol, bound for a patrol area in waters off the eastern coast of Japanese-occupied British Malaya. She made no ship contacts worthy of torpedoes and, on 4 June 1945, left her patrol area. She terminated her patrol at Subic Bay on Luzon in the Philippines, where she underwent a refit alongside the submarine tender . Third war patrol On 3 Jul 194y, Brill stood out to sea for her third war patrol. She arrived in her patrol area in the Gulf of Siam
