As a matter of fact, the ROK regiment took 16 Chinese prisoners in all. They were identified as belonging to two regiments of the 124th CCF Division, one of the three divisions of the 42d CCF Army. This force had crossed the Yalu about 16 October, according to POW testimony, and moved southward without being observed into the Chosin Reservoir area during the following ten days.[208] [208] Smith, _Notes_, 534; 1stMarDiv _PIR_ 4; 1stMarDiv _SAR_, 30. These prisoners were later interrogated by Gen Almond himself and formed the basis of the first official report of Chinese intervention. Almond Comments, 21 Jun 56; FECOM msg C67881, 31 Oct 50. Not only was Colonel Litzenberg aware that he would be facing Chinese adversaries in this area; he also suspected that they had infiltrated toward his left rear. He sent a patrol consisting of 20 men and five jeeps of Recon Company as far as Chigyong on the 31st without making any enemy contacts. The following morning CO RCT-7 ordered Recon Company in 21 jeeps to conduct a reconnaissance to the Huksu-ri area, approximately 45 miles northwest of Hamhung. After bypassing a blown bridge, First Lieutenant Ralph B. Crossman’s force dug in for the night 4500 yards short of its objective. Shots were exchanged several times that night and early the following morning with North Korean guerrillas in company strength, but the patrol returned with a negative report as far as Chinese forces were concerned.[209] [209] Maj R. B. Crossman, Capt C. R. Puckett, and Capt D. W. Sharon interv, 20 Oct 55; HqBn, 1stMarDiv (hereafter HqBn) _URpt 8_ (_Supplementary_), 2. Maj Webb D. Sawyer, CO 2/7 and Maj James F. Lawrence also made helicopter reconnaissances of the same ground looking for possible flanking routes to Koto-ri. Sawyer Comments, 7 Sep 56. News was received on 1 November of the heavy losses taken by the 1st Cavalry Division at the hands of the Chinese in northwest Korea. There was no change, however, in Corps orders calling for the advance of Litzenberg’s regiment to the border. Koto-ri, 23 road miles north of Majon-dong, was the first objective. The right flank of the Eighth Army was about 60 air miles southwest of Majon-dong, so that RCT-7 must advance without protection for its left flank except for Division Recon Company, which was to be relieved as soon as possible by RCT-1. “Under these circumstances,” commented General Smith at a later date, “there was no alternative except to continue forward in the hope that the Eighth Army situation would right itself and that we would succeed in our efforts to close up the entire 1st Marine Division behind RCT-7.”[210] [210] Smith, _Notes_, 523–524.
