On 15 March 1951, a seven-ship naval bombardment of the Wonsan district resulted in reported enemy casualties of some 6,000. The following afternoon, shore batteries fired at the ships in the harbor, and counter-battery fire from the destroyers began in a matter of seconds. Gun positions were taken under fire, and several explosions were noted on the peninsula. On 17 March, "Wallace L. Lind" patrolled independently from Wonsan south along the coast. The ship took the city of Kosong under fire and exposed and silenced a camouflaged shore battery located south of Suwon Dan lighthouse.
