"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.
