No opposition awaited the column. This unnatural calm continued for 4½ hours as the Marines advanced about 11 miles. At noon, with Sachon only 4 miles away, Houghton and the point rounded a bend into the thatched-hut hamlet of Changchon. The first enemy soldiers of the day were sighted when two skulking figures took cover. Several Marines opened fire, and in reply the hills on both sides of the road erupted into flame.[264] [264] This section is derived from: Brig SAR, 5th Marines, 1st Bn rpt; Maj John L. Tobin, ltr to author, 26 Apr 54 (Tobin, 26 Apr 54); Maj John R. Stevens, ltr to author, 11 Jan 54; and T/Sgt F. J. Lischeski, ltr to author, 14 Jan 54. The enemy had obviously planned to allow the entire column to come within range. But the trap was sprung prematurely as NKPA machineguns blazed away from the high ground in front and on both flanks. Captain Tobin immediately sent the 1st Platoon to the aid of the point. First Lieutenant Hugh C. Schryver led his men forward along the roadside ditches, and at the cost of three casualties they reinforced the thin line of Recon troops returning the enemy’s fire. Next, the company commander ordered First Lieutenant David S. Taylor’s 2d Platoon to move up behind three Marine tanks. The M-26’s were unable to maneuver off the road because of the danger of bogging down in rice paddies, but as mobile fortresses they added to Marine fire power. [Illustration: SACHON OFFENSIVE CHANGCHON AMBUSH 12 AUGUST 1950] Tobin’s whole company became more or less pinned down when the 3d Platoon and headquarters, farther back on the road, received automatic weapons fire from Hill 250 on the right. Newton immediately requested the battalion air controller, First Lieutenant James W. Smith, to call for a strike in this area. This was the only supporting arm available at the moment, since the mortar and artillery crews were just setting up their weapons in hastily selected positions. After the Corsairs worked over Hill 250, Tobin ordered Second Lieutenant David R. Cowling’s 3d Platoon to attack the high ground. A rifle platoon and machinegun section had been sent forward from Able Company by the battalion commander, and Newton gave these reinforcements the mission of seizing Hill 301, also on the right side of the road. As Cowling’s men were crossing the open rice paddy, the Marine tank guns and mortars added their fires to the air strike. But enough enemy machineguns survived to catch the 3d Platoon in a crossfire which forced it to fall back with 1 man killed and 4 wounded. The Able Company contingent occupied Hill 301 meanwhile without meeting any resistance.
