After a month of such operations, she returned to Sasebo for upkeep. From 1 April 1951 to 3 November, "Thompson" returned to shell communist defense positions, supply lines, and troop concentrations. On 14 June, however, it was the enemy's turn to hit back. "Thompson"’s gunners had just completed the destruction of a railroad bridge near Sŏngjin when communist shore batteries opened fire, soon straddling the ship. One shell struck the bridge and knocked out the ship's fire control gear. In retaliation, "Thompson"’s gunners destroyed one enemy battery and damaged another. With three dead and three wounded, "Thompson" retired.
