RCT-1--To protect the right flank of the Division and be prepared to assemble in Division reserve by battalions for a motor lift. Blocking positions, as assigned by OpnO 13-50, consisted of high ground from two to five miles northeast of Seoul. RCT-5--To continue reconnaissance in force with minimum of a reinforced battalion to Suyuhyon and establish a blocking position; to protect the left flank of the Division; and to be prepared to provide a reinforced rifle company for Task Force Kumpo, on order. These attachments to be made: 1st Battalion, 11th Marines, and one battery of 50th AAA Battalion, USA; Company A, 1st Tank Battalion; Company A, 1st Engineer Battalion; and a company from the 1st Motor Transport Battalion. RCT-7--To advance rapidly and seize blocking positions in the vicinity of Uijongbu. These attachments to be made: 3d Battalion, 11th Marines, and one battery of 50th AAA Battalion, USA; Company D, 1st Tank Battalion; and one company of the KMC Regiment. The KMC Regiment (less the 1st and 3d Battalions and one company of the 5th Battalion, with a detachment of ANGLICO attached) was meanwhile to advance to the east and seize blocking positions at the junction of the Han and Pukhan rivers where the road leading northeast from Seoul reaches that point. The 1st KMC Battalion had been attached to the 7th Infantry Division, and the 3d Battalion was operating on the Kumpo Peninsula. Task Force Kumpo, when activated on Division order, was to consist of the 3d KMC Battalion and Battery C, 50th AAA Battalion, USA, plus a 5th Marines rifle company and a tank detachment, if required. As it proved, however, X Corps held responsibility for the defense of this area until 2 October, when the 187th Airborne RCT was relieved by Task Force Kumpo.[461] [461] _Ibid._, 318–319, 336–337. Both “Kimpo” and “Kumpo” are used in reports to designate the same area--the peninsula formed by the mouth of the Han. The first name was derived from the airfield, of course, and the second from the principal town of the peninsula. Two more small fire fights awaited the 5th Marines in carrying out the missions assigned by Division OpnO 14-50. At 1030 on 1 October, while patrolling the extensive area of regimental responsibility, a detachment of 2/5 made contact with an NKPA force estimated at 150 to 200 men. Air strikes and mortar fire soon took the fight out of the enemy, who left 30 dead behind. At 0600 on 1 October the 3d Battalion, reinforced with a battery of artillery and a platoon of tanks and engineers, moved out toward Suyuhyon. Charlie Company of 1/5 followed in trace to protect the battalion rear and provide security for returning motor transport.
