George Company, 3/1 lacked organic transport and was mounted in the vehicles of 7thMTBn. For similar reasons ServCo, 1stTkBn, supplied the transportation for the 41st Commando and 377th Transportation Truck Company, USA, for B/31stInf. At 1350 the head of the column had resumed the advance, with the order of march as shown below: D/TKs & AT/5 -- G/1 -- 41 Cmdo -- B/31 -- HqBn -- B/TKs 17 tks 22 veh 31 veh 22 veh 66 veh 12 tks Shortly after moving out, Sitter’s men were hit by heavy small-arms fire from houses on the right of the road. The company commander went forward and requested the tanks to open up with their 90mm guns, and the Chinese flushed out of the houses were destroyed by machine-gun fire. Progress was slow because of the necessity of further halts while the tanks blasted out pockets of CCF resistance. Enemy mortar as well as small-arms fire was encountered, and a round scored a direct hit on one of the trucks carrying personnel of 3d Platoon of George Company, wounding every man in the vehicle. Further delays resulted while the tanks made their way over roadblocks or around craters. For the three infantry companies, the advance consisted of brief periods of movement alternated with interludes in which the troops scrambled out of the trucks to engage in fire fights. Finally, about 1615, the column ground to a complete halt about four miles north of Koto-ri. At that time the tanks of Company B were just leaving the 2/1 perimeter to join the convoy. _The Fight in Hell Fire Valley_
