Lieutenant Colonel Drysdale’s plan of attack had called for his British Marines to lead out at 0930 and seize the first hill mass to the east of the road. Captain Sitter’s George Company of 3/1 was to follow and pass through to attack Hill 1236, with Baker Company of the 31st Infantry in reserve. LtCol Sutter, assisted by his staff, had the responsibility for planning and coordinating preparatory artillery and mortar fires from Koto-ri and attaching an air liaison officer to the task force.[468] [468] Unless otherwise specified, this section is based on: CO 41st Commando ltr to CG 1stMarDiv, 30 Nov 50; 1stTkBn _SAR_, 23–27; Smith, _Notes_, 859–868; Maj C.

The first hill was taken without meeting serious resistance, but Sitter came up against well entrenched CCF troops when he attacked Hill 1236, about a mile and a half north of Koto-ri. It was nip and tuck until Master Sergeant Rocco A. Zullo fired his 3.5 rocket launcher at a range of 200 yards. Several rounds brought the Chinese out of their holes and the Marines took possession of the hill. [Illustration: ATTEMPTS TO REINFORCE HAGARU 28 November-1 December MAP-20 ] The Commandos and George Company moved up about a mile astride of the road toward the third objective, Hill 1182. There the enemy resisted strenuously with well-placed mortar as well as machine-gun fire from strong positions on the high ground. The impetus of the attack had been stopped when Sitter received orders from the task force commander to break off action, withdraw to the road, and await new instructions. Drysdale had received a message from RCT-1 at 1130 advising him that the armor of Company D (less 2d platoon), 1st Tank Battalion, would be available to him at 1300. He decided to wait, therefore, and re-form the column before continuing the advance. The two platoons of Company D tanks, reinforced by the tank platoon of the AT Company, RCT-5, reached Koto-ri at noon after moving out that morning from Majon-dong. Company B, 1st Tank Battalion, departed Tongjong-ni, just south of Majon-dong, but did not arrive at Koto-ri until 1500. The 2d Platoon being attached to Sutter’s battalion, the remainder of the company was directed to bring up the rear of the Task Force Drysdale, which by that time had renewed its attack. Thus the convoy was made up of the following components, including the elements which joined in the late afternoon of 29 November:
