She left the company of the carrier force on 2 December and, screened by the destroyer Wiltsie, provided gunfire support for the Republic of Korea (ROK) Corps in the Kasong-Kosong area. After disembarking Admiral Denebrink on 3 December at Kangnung, the battleship resumed station on the Korean "bombline", providing gunfire support for the American 1st Marine Division. Wisconsin's shelling accounted for a tank, two gun emplacements, and a building.[5] She continued her gunfire support task for the 1st Marine Division and 1st ROK Corps through 6 December, accounting for enemy bunkers, artillery positions, and troop concentrations.[5] On one occasion during that time, the battleship received a request for call-fire support and provided three star-shells for the 1st ROK Corps, illuminating an enemy attack that was consequently repulsed with considerable enemy casualties.[5]
