Assigned to TE 95.20 on 11 October, "Lewis" and RoK "PC 706" carried out anti-shipping patrols between Wonsan and Hungnam and warned neutral shipping such as Japanese fishing boats out of the coastal defense zone. Two nights later, "Lewis" took fire from a radar-controlled enemy gun battery, observing 28 air bursts and 56 water splashes during the duel, some of which exploded as close as while others bracketed the evading destroyer escort out to . In return, the destroyer escort fired 178 high explosive and 36 white phosphorus rounds, observing one direct hit on a gun emplacement followed by a secondary explosion and fire. The following day, 14 October, "Lewis" spotted five sampans off Cha Ho and drove them ashore with radar-directed long range gunnery. A week later, on 21 October 1952, "Lewis" came to the aid of two RoK minesweepers under fire in Wonsan harbor. As she approached, at least four enemy batteries opened up on the destroyer escort. "Lewis" returned fire and laid down a smoke screen to cover the minesweepers retreat. Shortly thereafter the destroyer escort took two shell hits, the first plowed into the forward fire room and pierced the No. 1 boiler – killing six fire and boilermen outright and mortally wounding a seventh; Fireman Milton S. Wheeler was awarded the Silver Star for carrying several of his injured shipmates to safety during this attack. The second hit exploded on the main deck, port side, lightly wounding one sailor. Following hull and machinery repairs at Yokosuka in mid-November, the destroyer escort sailed for home on 17 November, arriving in San Diego via Pearl Harbor on 2 December.
