to attack the convoy from a position away from Baya. Afterward, Baya attempted to contact Lagarto but her calls went unanswered. Lagarto was never heard from agan, and Japanese records indicated that the minelayer sank a submarine in that location at that time. Lagarto was lost with all hands. Baya shifted her patrol to the Java Sea, where on 13 May 1945 off Rembang, Java, she attacked a three-ship convoy consisting of the tanker Yosei Maru, the tanker Enoshima Maru — which she misidentified as a cargo ship — and an escort bound for Palembang, Sumatra. She chose Yosei Maru as her first target and scored three hits with a spread of six torpedoes. She then aimed her stern tubes at the escort, and believed she scored two hits. To make a clean sweep, she fired her two remaining torpedoes at Enoshima Maru and retired, leaving Yosei Maru sinking and, her crew believed, the other two ships severely damaged. The guard boat No.17 Shonan Maru carried out an unsuccessful counterattack on Baya. Although Baya claimed to have sunk Enoshima Maru, the latter had, in fact, escaped unscathed. On 18 May 1945, Baya reached Fremantle for a refit alongside the submarine tender . Fifth war patrol A fire in the maneuvering room delayed the start of Baya′s fifth war patrol, but after the completion of repairs, she got underway on 20 June 1945. At the beginning of the patrol, she operated south of Cape Selatan in support of Allied landings at Balikpapan, Borneo. On 27 June 1945, she intercepted a single Japanese minelayer but her torpedoes missed. On 29 and 30 June 1945, Baya and the submarine conducted a coordinated gun attack on five Japanese small craft. Heavy return fire ended this engagement before Baya could add another sinking to her record. Baya performed lifeguard duties in the Java Sea during the first half of July 1945 and then continued her patrol in that same area. On 16 July 1945, she torpedoed and sank the Japanese Ōtori-class torpedo boat , then en route from Surabaya, Java, to Ambon with two torpedoes; two officers, 22 men, and one civilian passenger who survived Kari′s sinking ultimately reached Masalamo Besar on 18 July. After an unsuccessful gun attack on another Japanese patrol craft, Baya received orders to proceed to Subic Bay on 26 July 1945. She reached Subic Bay on 31 July 1945 and
