[378] Unless otherwise stated this section is derived from: 7thMar _SAR_, 20–21; RCT 7 _URpt 5_; 3/7 _SAR_, n. p.; 2/5 _SAR_, 15–18; 2/5 _HD, Nov 50_, 9; 1stMarDiv _SAR_, annex SS, appendix A (hereafter 1/11 _SAR_), 8–9; VMF-312 _SAR_, 15; CO 7thMar msg to CG 1stMarDiv, 1945 27 Nov 50; LtCol M. A. Hull Comments, n. d. During 3/7’s operations on the high ground the 2d Battalion, 5th Marines, had marched out of Yudam-ni and launched the main attack along the road. Company F, under Captain Uel D. Peters, led 2/5 as it passed beneath the steep walls of Southwest and Northwest Ridges. The first objective was a long spur of the latter height, 500 yards across a draw from the 7th Marines on Hill 1403. Approaching the mouth of the draw on the right of the road, Fox Company was hit by long-range small-arms fire from enemy emplacements on the objective. About the same time, 0935, a message from the VMO-6 spotter plane told of CCF positions all across the front. Captain Peters held up momentarily to appraise the situation, and engineers moving behind his outfit began to clear the first of nine unmanned enemy roadblocks that obstructed the MSR. [Illustration: MARINE ATTACKS - 27 NOV MAP-13 ] According to plan, Company F ascended part way up the slopes of Hill 1403 and then advanced across the front of the 7th Marines to the head of the long draw that set off the Communist-held spur. Simultaneously, 4.2-inch and 81mm mortar crews positioned their weapons along the road to support this envelopment. The flatlands south of Yudam-ni trembled as the 105mm howitzers of Lieutenant Colonel Harvey A. Feehan’s 1st Battalion, 11th Marines, opened up at 1015 with a 15-minute preparation.[379] [379] Feehan, on 15 Nov 50, had relieved LtCol Ransom M. Wood who had commanded 1/11 since its arrival in Korea with the 1st ProvMarBrig on 2 Aug 50. While Company F moved overland to strike at the left (north) flank of the CCF position, Captain Samuel S. Smith’s Dog Company edged forward along the MSR to the mouth of the draw. Like the earlier unit, it was met by a hail of bullets. The regimental 4.2-inch mortars opened fire on the crest of the spur, and recoilless rifles slammed 75mm shells into bunkers just now sighted on the forward slopes. At 1115, after ground supporting arms had partially neutralized the CCF positions, Corsairs of VMF-312 blasted the objective with rockets and bombs.
