"Manning" reported for duty with the Philippine Sea frontier on 6 March. Two days later, she sailed in the screen of a convoy bound for the Admiralties. For more than two months she escorted convoys out of Leyte to New Guinea, the Palaus, the Admiralties, and back. As U.S. ground forces, buttressed by the might of American seapower, secured control of the Philippines, "Manning", in mid-May, resumed ASW patrols in the South China Sea. Operating out of Manila, she patrolled the American convoy lanes from Subic Bay to the southern tip of Mindoro during the final three months of fighting in the western Pacific.
