late on the 10th, march east for four days, then attack the US 2nd Division and the ROK divisions on the eastern front. Another captive taken on the 13th in the same general area said that the 15th Army was to march east for three days and attack the 2nd Division in conjunction with KPA attacks on the ROK front. Large enemy groups reported by X Corps' observers to be moving east as far as Yanggu on the 11th and 12th were believed to be PVA, and a deserter from the engineer battalion of the 80th Division, 27th Army, picked up on the 13th in the Chuncheon area stated that his battalion had been bridging the Pukhan. The X Corps intelligence officer believed it most likely, however, that the forces moving east of the Pukhan as far as Yanggu were from the 39th Army or 40th Army, both of which had been in the east central sector for some time. In any event, he considered major PVA operations on the eastern front to be impracticable. Given the logistical difficulties the PVA experienced in supporting offensive operations even in the Seoul area, where the distance to their rear supply bases was shortest and where the roads were more numerous and in better condition than anywhere else, he doubted that they would commit a large force in the eastern mountains where a supply line could not be maintained and where living off the land would be almost impossible. The Eighth Army intelligence staff as of 16 May had no corroborating evidence of the reported movement east of the Pukhan and even had some doubt that the PVA shift extended as far east as Chuncheon. According to the consensus of current estimates of PVA/KPA dispositions as of the 16th, KPA I Corps on the west had spread forces eastward toward Route 33, taking over ground previously occupied by the PVA XIX Army Group. The 65th Army astride Route 33 north of Uijeongbu and the 63rd Army in the adjacent ground to the east formed the new front of the XIX Army Group. Reports placed the 64th Army northwest of the 65th. West to east, the 60th, 15th and 12th Armies were believed to occupy the new front of the III Army Group from a point above the Pukhan River in the vicinity of Kapyong eastward almost to Chuncheon. More tentatively located, the 20th
