The 1st Marines regimental right boundary, which on the MLR was 1,100 yards north of the 38th Parallel, separated the 1st Marine Division area from the western end of the 1st Commonwealth Division, then held by the 25th Canadian Infantry Brigade. In late March, Colonel Wade’s 2/1 (Lieutenant Colonel Thell H. Fisher) and 3/1 (Lieutenant Colonel Spencer H. Pratt) manned the frontline positions while 1/1 (Lieutenant Colonel John H. Papurca), less Company A, was in reserve. The regiment was committed to the defense of its part of the division area and improvement of its ground positions. In the division center sector Colonel Culhane’s 1/5 (Lieutenant Colonel Franklin B. Nihart) and 3/5 (Lieutenant Colonel William S. McLaughlin) manned the left and right battalion MLR positions, with 2/5 (Lieutenant Colonel William H. Cushing) in reserve. The latter unit was to be prepared either to relieve the MLR battalions or for use as a counterattack force. It did not take the Marines long to discover the existence of serious flaws in the area defense which made it questionable whether the Allied line here could have successfully withstood an enemy attack. While his Marine units were effecting their relief of JAMESTOWN, Colonel Wade noted that “field fortifications were practically nonexistent in some sections.”[22] General Selden later pointed out that “populated villages existed between opposing lines. Farmers were cultivating their fields in full view of both forces. Traffic across the river was brisk.”[23] A member of the division staff reported that there was “even a school operating in one area ahead of the Marine lines.”[24] In addition to these indications of sector weakness, there was still another. Although the ROK division had placed three regiments in the line, when the two Marine regiments relieved them there were then more men on JAMESTOWN due to the greater personnel strength of a Marine regiment. Nevertheless, the division commander was still appalled at the width of the defense sector assigned to so few Marines. [22] 1stMar ComdD, Mar 52, p. 2. [23] 1stMarDiv ComdD, Jun 52, App IX, p. 1.
