After voyaging to Manus for replenishment, "Cony" returned to Leyte Gulf for patrol duties 16 November 1944. On the nights of 29–30 November and 1–2 December she joined in sweeps of Ormoc Bay, hunting Japanese shipping. Targets were few, but her group sent a barge to the bottom on their second foray, and bombarded enemy positions on the shores of the bay in preparation for the landings in Ormoc Bay a few days later. "Cony" put into Kossol Roads from 4 to 10 December, then sailed to screen carriers providing air cover for attack groups passing from Leyte to Mindoro, returning to Kossol Roads 19 December.
