On 11 October, "Alshain" reached the Inchon area and loaded equipment and supplies for an upcoming amphibious operation. She departed Inchon on the 17th with TG 90.2, bound for Wonsan, Korea. However, clearance of mines delayed the start of the assault on Wonsan; and the task group was forced to retire along its approach route and wait. In the interim, South Korean forces moving north captured Wonsan and obviated the need for an assault landing. Thus when "Alshain" returned on the 26th to unload cargo and disembark troops, no enemy harassed her cargo operations, and she completed the mission on the 31st.
