On the other Marine front, 25 miles distant, 1/5 had a return engagement before dawn on 13 August with the enemy in the Changchon area. Company commanders had received orders the night before to alert their units at 0400 for the withdrawal. General Craig’s Op Order 10-50 was a complete and well planned field order, despite the need for haste; but the enemy interrupted with a surprise attack launched from concealed positions occupied under cover of darkness.[267] [267] Craig, 12 Jan 54. Baker Company’s defense setup for the night on Hill 202 consisted of the 3d, 1st, and 2d Platoons tied in from left to right in that order. The action began at 0450 with enemy automatic weapons fire. Marine 60-mm. mortar illuminating shells revealed an NKPA infiltration on the right in the area of the 2d Platoon. This effort soon proved to be a diversionary attack for the purpose of masking the main blow. At 0455 3 enemy flares went up, 2 red and 1 green. They were the signal for an assault on the left flank at the other end of the Baker Company position. The enemy, as a wounded Marine NCO put it afterwards, was “right on top of the 3d Platoon in a few seconds” with grenades and burp guns.[268] [268] Tobin, of 26 Apr 54. This was one of the occasions when the Marines were painfully reminded that the NKPA 6th Division had been made up originally of veterans of the Chinese civil war, conditioned by experience for the rigors of night fighting. Marine security had not been at fault, yet the enemy had managed to creep forward in uncanny silence to positions within grenade-throwing distance. In an instant the Marine position was overrun, with the machinegun section being wiped out except for two men. Communication troubles added to the confusion. Platoon radios had been rendered inoperative by mud and water while crossing rice paddies, and telephone wires were believed to have been cut. Two runners were killed during Tobin’s efforts to maintain contact with the hard-pressed troops on the left flank. A third runner got through with orders for the remnants of the platoon to fall back within the perimeter of the adjacent 1st Platoon. The troubles of Baker Company were compounded at this stage when the enemy turned two of the Marines’ own machineguns against them.
