[270] Seven of these casualties were transferred from the MIA to the KIA column in September 1950 after the recovery of their bodies, following enemy withdrawal from the area. The eighth continued to be listed as MIA until November 1953, when the man was assumed to be dead. [271] _Ibid._ It fell to the engineers and armor to cover the rear after the infantry pulled out. Midway between Sachon and Kosong, the MSR is joined by a road from Samchonpo, a minor seaport on the tip of the peninsula. In order to block this approach to the Brigade’s southern flank, General Craig ordered the engineers to mine the road. First Lieutenant Nicholas A. Canzona was assigned to the task with a detachment of his 1st Platoon of Able Company, 1st Engineer Battalion. After laying an extensive field, this officer discovered to his embarrassment that he had erred in arming nearly half of the mines with wrong fuses, so that they were harmless. Apparently the moral effect was enough, however, to keep the enemy at a distance. Lieutenant Hetrick’s 3d Platoon of the engineer company brought up the Brigade rear on the morning of 13 August to crater roads, lay antitank minefields and destroy bridges and culverts. Personnel left behind for such missions had the privilege of riding the rearmost tank to catch up with the column.[272] Thus the withdrawal proceeded systematically and was completed without enemy interference.
