The destroyer-escort returned to the United States in early 1946 for shipyard overhaul at San Pedro, California. On 16 May, she once again departed for the South Pacific. Arriving at Kwajalein on 31 May, she provided power to that island until September. During her tenure there, a slight mishap occurred. A group of sailors while on leave left the ship and proceeded to burglarize a large liquor storehouse that was on the island. They were discovered by Marine MP's that were stationed on the island. None of them were apprehended, but it is known that those who committed the robbery were from the "Marsh" because a small dinghy belonging to the Marine Detachment was stolen that night as well, and tied up alongside the destroyer. The officer in charge of the division claimed that it was theirs and that the liquor had been stolen by sailors on board the "Marsh". The captain of the vessel staunchly denied the claims. No arrests were made and the small dinghy remained with the "Marsh" at least until 1947. She then sailed for Guam where she received orders for Tsingtao and Fusan, Korea where the 7th Fleet lent support to the aims of American policy in China and in the United States occupation zone of Korea.
