Retto when an enemy torpedo bomber executed a near-perfect run on her. Initially, the plane was thought to be friendly, though the radarman continued to track the unidentified aircraft just in case. The pilot lined his plane up with the moon, made a well-executed approach, and launched his torpedo. Two sharp-eyed sailors on board Triumph spied the torpedo splash, raised the alarm, and the warship immediately went hard to starboard to evade the torpedo. It passed in her wake, a scant 30 yards astern. Darkness precluded any real antiaircraft response, so Triumph resumed her patrols. Three days after that attack, the minesweeper put into Kerama Retto for supplies and upkeep. Triumph remained in Kerama Retto through the end of June. On the 30th, she got underway to rehearse for sweeps into the East China Sea. Those preparations continued until Independence Day when she sortied with Task Unit TU 39.11.6. She arrived in the assigned area with the rest of her unit on the 5th and conducted a highly productive, eight-day sweep unimpaired by Japanese air activity. She returned to Buckner Bay, located on the western coast of Okinawa, on Bastille Day. There she replenished and refueled over a three-day period before returning to the East China Sea to resume mine-sweeping operations. However, just before beginning that mission, she was detached from the East China Sea minesweeping force and was ordered to report to task force TF 39 for further orders. On 17 July, she was forced to leave the anchorage at Buckner Bay to evade a typhoon. After serving in the antisubmarine screen of the ships forced out of the anchorage, the warship returned to Buckner Bay on 21 July and remained there, awaiting orders, until 5 August. On that day, she stood out of the bay as a unit in the screen of a convoy of tank landing ships. Japan capitulates Two days later, she took PGM-11 in tow after the latter ship suffered an engine casualty. On the 11th, Triumph parted company with the convoy to tow PGM-11 into Apra Harbor, Guam. With and YMS-341 in escort, the minesweeper entered Apra Harbor on the morning of 12 August. Three days later, she received word of the Japanese capitulation. Triumph remained at Guam for a month undergoing repairs. She departed on 12 September to participate in the occupation of Japan and former Japanese possessions. She served her entire tour
