For the next month and a half, "Manchester" patrolled off the east coast of Korea. Firing at both shore and inland targets, she blasted communication and transportation centers, destroying and disrupting the enemy's equipment and troop concentrations. On 22 February, she steamed to Wonsan to add her guns to the siege and blockade of that port which had commenced five days earlier. She continued to conduct shore bombardment activities along the northeast coast, primarily at Wonsan and Songjin, for the remainder of her first Korean combat tour.
