"Willoughby" and her sister ship "Wachapreague" retired from Leyte on 13 November 1944 and arrived at Mios Woendi on 16 November. On 17 and 18 November 1944, the motor torpedo boat tenders loaded stores and supplies. Later, in company with motor torpedo boat tender USS "Pontus" (AGP-20), "Wachapreague", seven Army crash boats and 41 PT boats, "Willoughby" departed New Guinea and proceeded vai Kossol Roads back to the Philippines, in a repeat performance of the previous mass movement of PT boats from New Guinea to that strategic archipelago. After servicing the PT boats en route, at Kossol Roads, on 23 November 1944, Willoughby steamed into Leyte Gulf, arriving late on 27 November 1944.
