After overhaul on the west coast, "Charles Ausburne" returned to Ulithi 5 November 1944, and through the remainder of November guarded carriers providing air cover for convoys to Leyte. Heavy air action came in December, when from 19 December to 24 December, the destroyer led the first resupply convoy from San Pedro Bay to Mindoro. On 21 December, four separate raids, one of which included kamikazes, met the fire of the screening destroyers, and more raids were fought off as the convoy unloaded.
