"Manning" completed her final patrol four days after the cessation of hostilities; and, as Japanese representatives signed the formal surrender documents on 2 September, she departed Subic Bay as escort for an Okinawa-bound convoy of LCTs and LCIs. After returning from Okinawa on 12 September, she sailed with other escorts of CortDiv 37 for the United States on 1 October. Steaming via the Marshalls and Pearl Harbor, she reached San Diego on 23 October and reported for duty with the San Diego group of the Pacific Reserve Fleet.
