Division OpnO 23-50, issued at 0800 on the 23d, directed the Commandos to locate and destroy enemy forces on the left flank, ranging as far as 13 miles west of Koto-ri. It was hoped that the British unit and the Division Reconnaissance Company might flush out CCF troops beyond the reach of routine infantry patrols. Other tasks assigned to elements of the Division were as follows:
RCT-7—to seize Yudam-ni and maintain one battalion in that position;
RCT-5—to seize Kyolmul-li (20 miles north of Hagaru) and be prepared to seize Toksil-li (10 miles northwest of Kyolmul-li) and Tuan-di (15 miles northeast of Kyolmul-li) on order;
RCT-1—to relieve elements of RCT-7 in the vicinity of Hagaru and Koto-ri and protect the Division MSR from positions in the vicinity of Hagaru, Koto-ri and Chinhung-ni;
1st Tank Battalion (less detachments)—to protect the MSR from positions in the vicinity of Majon-dong and Soyang-ni;
1st Engineer Battalion—to support Division operations with priority to the maintenance of the MSR and construction of the airfield at Hagaru.
OpnO 23-50 also provided that the Supply Regulating Station Detachment continue operation of the truckhead at Hagaru and stock supplies at the following levels: Classes I and III, 8 days; Classes II and IV, as required; and Class V, one and one-third U/F for all troops operating to the north and west of Chinhung-ni.[345]

The trucking facilities of the Division had been strained to the limit ever since the Wonsan landing. Shortly afterwards the bulk of the 7th Motor transport Battalion was taken under the operational control of X Corps, and it became necessary to attach the 1st Motor Transport Battalion to RCT-7. On 19 November, however, the 1st MT (less detachments) had passed to the control of the 1st Supply Regulating Detachment at Hagaru. There the truckers not only built up the stockpile of supplies but rendered the best support that units of the division had known so far along the MSR.[346]
