She patrolled there on 9 and 10 February while the men and supplies were unloaded, then sailed to San Pedro Bay, Leyte, 14 February. She continued to escort supply convoys from Morotai and Leyte to Subic Bay and Lingayen Gulf until the 27th when she was assigned to the San Bernardino-Verde Islands Minesweeping unit guarding minecraft as they cleared the sea lane to Manila, as well as taking part in naval and amphibious operations along this route.
