included the submarines and . During January 1945, Bluegill conducted a reconnaissance in support of the American liberation of the campaign in the Philippine Islands. The only other event of note during the patrol occurred on 2 February 1945, when she took aboard two Japanese prisoners-of-war that another American submarine had captured for passage back to Fremantle, which she reached on 7 February 1945. Fifth war patrol Bluegill began her fifth war patrol on 12 March 1945 and transited Lombok Strait on the night of 18–19 March 1945. Early on 19 March, she made an unsuccessful submerged torpedo attack on an auxiliary sailing vessel and the "sea truck" it was preparing to take in tow. Following fruitless searches along the coast of Borneo, Bluegill arrived off Japanese-occupied French Indochina on 27 March 1945. She submerged off Hon Doi to join the submarines and in a picket line along the coast. At around 10:20 on 28 March 1945, Bluegill heard a combination of sonar pings and depth-charge explosions to the south as Blackfin attacked the Japanese convoy HI-88J as it moved up the coast of French Indochina. Bluegill began to edge quietly toward the fracas as the three submarines, in concert with United States Army Air Forces planes, began an onslaught against the convoy. Just before 11:00, Bluegill made contact with the 5,542-gross register ton tanker Honan Maru (formerly the British Royal Fleet Auxiliary tanker War Sirdar) escorted by four coast defense vessels and a destroyer. A little before 11:15, she fired three torpedoes at Honan Maru. Two of them struck home, but Honan Maru managed to ground herself on the nearby shore to avoid sinking and permit salvage. Meanwhile, Bluegill contended with a savage depth charge attack from the escorts. On 29 March, she fired two more torpedoes at the stranded Honan Maru. On 5 and 6 April 1945, Bluegill attempted a commando raid to blow up bridges and trains in French Indochina. The Japanese detected the Australian commandos, and the attempt ended in failure. Meanwhile, Bluegill returned to Honan Maru on 5 April and sent ashore a landing party that ascertained Honan Maru′s identity and completed her destruction with demolition charges and incendiaries. She concluded her patrol at Subic Bay on Luzon in the Philippine Islands on 18 April 1945. Sixth war patrol Bluegill put to sea from Subic Bay on her sixth war patrol, assigned a patrol area
