A comparatively few men, giving way to panic, were endangering the entire column. Behind one of the fleeing trucks an angry warrant officer pounded in pursuit, shouting some of the most sulphurous profanity that Lieutenant Colonel Taplett had ever heard.[534] This was CWO Allen Carlson of Baker Battery, 1/11. He disappeared around a bend in the road, only to return a moment later with a chastened driver towing a 105mm howitzer. Carlson hastily recruited a crew and set up the piece beside the road for point-blank fire at the enemy position while Taplett directed the fire of a 75mm recoilless rifle. [534] Taplett interv, 8 Jun 56. A Charlie Battery howitzer and a 1/5 heavy machine gun added their contribution as a platoon of Easy Company, 2/5, attacked under cover of air strikes. The Chinese position was overrun at 0830 at an estimated cost to the enemy of 150 dead. Two other attacks were launched by infantry units of Roise’s battalion on the high ground to the left before the MSR was cleared. When the 155mm howitzers were pushed off the road, it had been assumed that they would be retrieved. Only 1000 yards farther down the MSR was a cache of air-dropped diesel fuel, but efforts to bring back replenishments were frustrated by enemy fire. Attempts at recovery by the British Marines failed later that day, and orders were given for the destruction by air of the eight stalled howitzers plus a ninth which had previously been abandoned after skidding off the road. This was the largest loss of weapons in the Yudam-ni breakout. At 1400 on 4 December the last elements of the rearguard, 3/7, entered the perimeter and the four-day operation passed into history. Some 1500 casualties were brought to Hagaru, a third of them being in the non-battle category, chiefly frostbite cases. It had taken the head of the column about 59 hours to cover the 14 miles, and the rear units 79 hours. “Under the circumstances of its execution,” commented General Smith, “the breakout was remarkably well conducted. Since centralized control of the widespread elements was a difficult task, particularly with a joint command, unit commanders were required to exercise a high degree of initiative.... The spirit and discipline of the men under the most adverse conditions of weather and terrain was another highly important factor contributing to the success of the operation and also reflecting the quality of the leadership being exercised.”[535] [535] Smith, _Notes_, 948.
