MAP 1 K. WHITE EUSAK DISPOSITIONS 15 MARCH 1952] It was hoped that the rearward movement of units from the front line and the subsequent inactivity there would cause the enemy to come out of his trenches to investigate the apparent large-scale withdrawal of UNC troops. Then Marine and other EUSAK troops could open fire and inflict maximum casualties from covered positions. On the fifth day of the operation, CLAM-UP was ended. The North Koreans were lured out of their defenses, but not in the numbers expected. CLAM-UP was the last action in the X Corps sector for the 1st Marine Division, which would begin its cross-country relocation the following month. (See Map 1.) Code-named Operation MIXMASTER, the transfer of the 1st Marine Division began on 17 March when major infantry units began to move out of their eastern X Corps positions, after their relief on line by the 8th Republic of Korea (ROK) Division. Regiments of the Marine division relocated in the following order: the 1st KMCs, 1st, 7th, and 5th Marines. The division’s artillery regiment, the 11th Marines, made the shift by battalions at two-day intervals. In the motor march to West Korea, Marine units traveled approximately 140 miles over narrow, mountainous, and frequently mud-clogged primitive roads. Day and night, division transport augmented by a motor transport battalion attached from Fleet Marine Force, Pacific (FMFPac) and one company from the 1st Combat Service Group (CSG) rolled through rain, snow, sleet, and occasional good weather. Marines employed 5,800 truck and DUKW (amphibious truck) loads to move most of the division personnel, gear, and supplies. Sixty-three flatbed trailers, 83 railroad cars, 14 landing ships, 2 transport aircraft, the vehicles of 4 Army truck companies, as well as hundreds of smaller jeep trailers and jeeps were utilized. The division estimated that these carriers moved about 50,000 tons of equipment and vehicles,[13] with some of the support units making as many as a dozen round trips. The MIXMASTER move was made primarily by truck and by ship[14] or rail for units with heavy vehicles. [13] Marine commanders and staff officers involved in the planning and execution of the division move were alarmed at the amount of additional equipment that infantry units had acquired during the static battle situation. Many had become overburdened with “nice-to-have” items in excess of actual T/E (Table of Equipment) allowances. Col William P. Pala comments on draft MS, 5 Sep 66, hereafter _Pala comments_.
