the South China Sea. Although she encountered and attacked two small convoys, their alert escorts foiled both attacks. Boarfish successfully carried out two reconnaissance missions along the east coast of French Indochina before ending her patrol in Subic Bay on 21 April. After refit alongside , Boarfish left Subic Bay on 16 May for the Java Sea. Her first action came when she sighted a small two-masted junk on 27 May. A boarding party searched the junk for arms, contraband, and Japanese, but found nothing, and the junk was allowed to proceed. Two days later, a small convoy of three ships accompanied by two escorts crossed Boarfishs path. She launched four torpedoes at the lead ship before losing firing position. Her crew heard an explosion; but, when the officer at the conn peered through her periscope, he saw a charging escort instead of a sinking ship. The submarine dived, intending to put of the charted at that location between her and the escort. At , the submarine grounded, knocking off her sound gear and making enough noise to betray her position easily. Eight depth charges followed as Boarfish tried to free herself. Despite damage to her port propeller, the submarine backed off the seamount and eased up to to escape. The damage sustained in the grounding was severe enough to force an early return to Fremantle, where she arrived on 8 June. After repair and refit alongside , she departed on 5 July for her fourth war patrol. Operating in a coordinated attack group Boarfish, , and covered the Java Sea off Java and the north coast of Bali. They made no surface contacts but encountered a number of enemy planes, one of which depth-bombed Boarfish on 8 July. On the 29th, Boarfish performed lifeguard duties during an Allied air strike on Singapore, and she remained off the Malay coast patrolling until 6 August, when she set course for Subic Bay. The submarine pulled alongside for refit on 10 August and was there when the Japanese capitulation was announced. 1945–1948 Boarfish sailed from Subic Bay on 30 August in company with Howard W. Gilmore and 17 submarines. She parted company with them on 5 September and put into Apra Harbor, Guam, where she remained until 17 November training in postwar maneuvers and drills. She got underway on 17 November and set course via Pearl Harbor for San Diego, Calif. where
