[481] 5thMar ComdD, Jun 53, p. 1. While the Marine infantry regiments concluded their training period, the 1st Tank Battalion, Kimpo Provisional Regiment, and Division Reconnaissance Company remained under operational control of the frontline U.S. 25th Infantry Division. Marine artillerymen likewise continued under orders of CG, I Corps Artillery, in the forward area, reinforcing division artillery fires. Tentative plans were underway for movement of the 1st Marine Division back to its former position on the MLR in early July. After the signing of the cease-fire, the division would comply with provisions of the truce agreement by closing out its former MLR and withdrawing to designated positions two kilometers south of the former defensive positions.

For the first week of July the 1st Marine Division continued its mission as I Corps Reserve and its two-month period of intensive combat training that had begun on 5 May. Planning got under way on 1 July, however, for return of the division to its former sector of the MLR, as the western anchor of I Corps, in relief of the 25th Infantry Division. Marine infantry components were directed by I Corps to effect the transfer of operational control during the night of 7–8 July. Tank and artillery units--already in the division sector throughout the reserve period--were to make whatever minor relocations were necessary at suitable times thereafter. Division Operation Plan 10-53 ordered the 7th Marines to reassume its responsibility for the right regimental sector of the MLR, eastward to the 1st Commonwealth boundary. The 5th Marines, which had been in reserve at the time of the May relief of lines, was assigned to the center sector of the MLR, while the 1st Marines was designated as divisional reserve.
