On the latter day, she sortied with the task group and set a course—via the Surigao Strait, the Sulu Sea, and the South China Sea—for Luzon. During the transit, enemy air attacks were frequent, but "William Seiverling" never got into the action until she arrived off Lingayen Gulf on 7 January. On that day, her guns warded off a single attacker whose approach was quite desultory in nature. She patrolled the waters off Lingayen Gulf until 17 January at which time she joined the screen of task group TG 77.4 and TG 77.3 and headed south. She conducted patrols with elements of the two task groups until 1 February when she began retirement through the Sulu Sea with TG 77.4.
