[Illustration: PURSUIT OF THE NKPA & CAPTURE OF UIJONGBU 28 SEP--3 OCT 1950] At least the day’s attacks had unmasked the enemy’s positions and exposed them to savage attacks by the Corsairs of VMF-312. RCT-7 continued the attack at 0630 on the 2d, with Roach on the left of the road and Davis on the right. About halfway through the defile the 3d Battalion was pinned down by a concentration of NKPA artillery, mortar, and small-arms fire. Again the tanks were held up while the engineers cleared away mines, working in a hail of bullets. The tanks of the 1st Platoon repaid the favor by closing in on two huts sheltering NKPA troops and killing an estimated 35. Here an attached dozer tank, without blade, had a freakish accident when two men in the turret were wounded by enemy fire down a 105mm gun tube while the breech was open. The 1st Battalion managed to cross the stream east of the defile and seize the high ground just beyond. But the day ended with gains of only 300 yards in the defile. Roach’s men returned to the attack in the morning, supported by the tanks of the 2d Platoon. Again VMF-312 flew one close air support sortie after another. Major Charles E. McLean was hit by enemy AA fire but crash-landed his plane in friendly territory. First Lieutenant Robert O. Crocker was killed in action shortly after being brought down by NKPA small-arms fire. VMF-312 fliers intercepted an enemy convoy and First Lieutenant Franklin Stratton reported the destruction of seven out of eight trucks. The tanks also gave the infantry helpful support, firing 167 90mm rounds during the day and an estimated 20,000 machine gun rounds at enemy troops along the ridge. While 1/7 cleared the high ground on the east side of the road and 3/7 on the west side, Colonel Litzenberg directed Major Webb D. Sawyer[465] to pass between them with 2/7 and drive directly along the highway. Progress was satisfactory from the start. When Sawyer’s men began to overrun abandoned NKPA artillery pieces and supply dumps, they pounded ahead with the realization that enemy resistance was broken. [465] Lieutenant Colonel Hinkle, the former 2/7 commander, had been wounded and evacuated on 28 September. At five that afternoon the 2d Battalion entered the ruins of Uijongbu, evacuated by the enemy. The last large-scale fight of the Inchon-Seoul operation had ended in a smashing victory for the Division’s youngest regiment.
