Exhibiting his characteristic faith in high explosives, Newton called on the 1st Platoon, Able Company Engineers, to contribute their sundry lethal devices to 1/5’s infantry defense. Beginning at 1800, 3 September, one group of engineers fanned out to the front and right flank of Company B’s lines. Despite fire from Hill 117 and enemy positions to the west, the demolitions men strung out dozens of antipersonnel mines, hand grenades, and blocks of TNT wrapped with 60-penny spikes. Before darkness set in, Baker Company’s forward slopes had the potential of an active volcano. In Company A’s zone, Technical Sergeant David N. Duncan and Sergeant Bryan K. White led the other half of the engineer platoon in laying a similar field of obstacles. Duncan crowned his handiwork with a 40-pound shaped charge hooked up in a gully with a trip wire. Staff Sergeant Saweren J. Dennis and his 2d Squad of engineers crept forward at midnight 1,000 yards on the MSR and laid an antitank minefield across the road near the southern tip of Hill 117. On the way Dennis discovered an enemy antitank minefield embedded in the road. Although the engineers had never seen a Russian wooden-box mine before, knowledge gained from the study of intelligence manuals during the Brigade’s sea voyage enabled them to detect, remove, and disarm every mine in the field during darkness. The work was delayed a few minutes when Dennis traced a clanking sound to the roadside ditch and killed a Communist soldier frantically trying to insert a loaded magazine into his submachinegun. Before the engineers completed their work and retired to 1/5’s lines, Nature added an obstacle of her own to any enemy plans for a counterattack. A rainstorm broke, and the heavy downpour, accompanied by unseasonably icy winds, wrought misery on friend and foe alike for the rest of the night. CHAPTER XII Mission Completed _Collapse of the 9th NKPA Division--Attacks of 5 September--Two Marine Tanks Killed--The Brigade’s Final Action--Brigade Embarkation at Pusan--Results of Brigade Operations--Summaries and Conclusions_ The casualties of 2/5 for 3 September totaled 18 dead and 77 wounded, most of them being taken by Company D. Lieutenant Colonel Murray ordered the 3d Battalion to pass through the 2d, therefore, and continue the attack on the right of the MSR at 0800 the next morning. The 1st Battalion was to resume its advance south of the MSR, while the Reconnaissance Company far out on the left would move forward to a new blocking position.[342] [342] This section is derived from: Brig SAR 3d Bn, 5th Marines (3/5) SAR, 1–6 Sep 50; Craig, 23 May 54; and Taplett, 20 Apr 54.
