In spite of this shortage, the flow of traffic was being maintained when an explosion of CCF activity brought every thing to a stop at Sudong shortly after midnight. Mountain defiles had usually been the scene of enemy ambushes, but this time the Chinese swarmed out from behind houses in the village with grenades and burp guns. Several truck drivers of the RCT-1 regimental train were killed by the first shots and their vehicles set on fire. In the flickering light a confused fight ensued as trucks to the rear stopped. The Marines of the RCT-1 train resisted as best they could, but leadership was lacking until Lieutenant Colonel John U. D. Page, USA, and Marine PFC Marvin L. Wasson teamed up as a two-man task force which routed a group of about 20 Chinese at the head of the vehicle column. The valiant Army artillery officer paid with his life, and Wasson received two wounds from a grenade explosion. Pausing only for first aid, he got back into the fight as another Army officer, Lieutenant Colonel Waldon C. Winston, commanding the 52d Transportation Truck Battalion, USA, directed a counterattack by Marine and Army service troops. Harry Smith, a United Press correspondent, also had a part in the action. Wasson called for a machine gun to cover him while he fired three white phosphorus rounds from a 75mm recoilless at a house serving the enemy as a stronghold. It burst into flames and the survivors who ran out were cut down by machine-gun fire. The Marine PFC, a jeep driver who was dubbed “The Spirit of ’76” by Winston, then volunteered to help push trucks of exploding ammunition off the road. Winston gradually brought order out of chaos, but it was daybreak before the MSR was cleared so that the column could start moving again. The RCT-1 regimental train had suffered casualties of eight killed and 21 wounded, while equipment losses consisted of nine trucks and an armored personnel carrier. Lack of infantry protection was a factor in another reverse which occurred at the tail of the Division column. General Smith’s final orders for withdrawal provided that the tanks were to come out behind the 1st Marines’ train with the infantry of that regiment bringing up the rear.[615] Thus a breakdown in the armored column would not block the road for wheeled vehicles, yet the tanks would have protection against close-in attack. [615] CG 1stMarDiv ltr to COs 1st, 5th, and 7thMars, 1530 9 Dec 50. The 1st Marines prepared detailed plans for the leapfrogging of battalions during the final withdrawal phase. In effect these called for 2/1 to relieve 1/5 on Objective D and remain there until relieved in turn by 2/31. The Army battalion would hold until 3/1 passed through, then follow Ridge’s battalion down the MSR. After 2/1, 3/1 and 2/31 had passed through Lieutenant Colonel Schmuck’s positions around Hill 1081, 1/1 would follow as rear guard.[616]
