Additional raids occurred that afternoon, but they caused no damage. By the morning of 14 December, the unit was passing Negros Island; and "Triumph", along with the rest of the minesweepers, received orders to sweep the waters ahead of the force. During that sweep, the unit was attacked by a formation of three Nakajima Ki-43s. The enemy planes dropped three bombs off "Triumph's" port quarter but caused no damage. An American combat air patrol drove the raiders off, and the minesweepers completed their mission by late afternoon. Just after midnight on 15 December, "Triumph" and her mates reached the beaches on the southwestern coast of Mindoro.
