At Chuuron Jang, she herself destroyed two railroad bridges with her pinpoint gunnery. Also during this period, she took part in "junk-busting" operations up and down the coast, being on the lookout for suspicious junks used by communist forces for infiltration and minelaying operations. On one occasion, while underway north of Sŏngjin, she sighted six North Korean junks in a cove. Once again, as at the Normandy "D-day" landings, "Thompson"’s gunners opened fire with a vengeance and sank all six communist boats.
