Allowing for a few changes, these were the positions held by major EUSAK units through the winter of 1951–1952.
The Marine move was launched by Division Operation Plan 2-52 and provided that the 1st Marine Division would be relieved by the 8th ROK Division as a preliminary to movement overland and by sea to the relief of the 1st ROK Division and defense of Line JAMESTOWN in the I Corps sector in the west. According to verbal orders later confirmed by EUSAK OI 272, transportation by truck and ship was specified, and the move was to be completed prior to 1 April.[371]
