While Captain Harlan’s company was exposed to this extremely heavy enemy artillery fire, another unit, B/1/7, was on the move from Lieutenant Colonel Dulacki’s command post to the ridge to strike what was intended as a lethal blow to the Communist invaders. At 1932, Company B began its march forward. By midnight, the 1st Platoon was nearing its assault position close to the left flank of Company I of 3/1. Simultaneously, the 3d Platoon closed in on its jump-off point. The going was extremely difficult, complicated by a moonless night and the many shell craters that pockmarked the terrain. But at 0019, 28 October, the platoons mounted their assault, firing their rifles and machine guns, and hurling grenades to silence enemy automatic weapons and to reach dug-in Communist soldiers occupying the trenchline. The Marine charge was met by a burst of small arms fire and a shower of grenades. Weapons supporting the Chinese defense were still very active. After a standoff of 90 minutes the Marines pulled back, calling on their mortars and artillery to lay precise fire concentrations on the trouble spots. The weapons also fired on enemy approach routes through Ronson and Warsaw. After this preparation, Company B again made an assault against the enemy, at 0340. This advance was contested vigorously by the Chinese, but their resistance this time was not lasting. Quickly B/1/7 Marines deployed throughout the entire area, and by 0600 the Hook was again in Marine hands. Before the victors could permit themselves the luxury of a breathing spell, there were a number of critical tasks that demanded immediate attention. Defense of the MLR had to be quickly and securely shored up for a possible enemy counterattack. The newly rewon area had to be searched for Marines, both casualties and holdouts, and for Chinese diehards or wounded. The company had to be reorganized. In addition to these missions, there were two others, regaining Ronson and Warsaw. As it turned out, the duties were discharged nearly at the same time. COPs Ronson and Warsaw were reoccupied by the 7th Marines at 0630 and 0845, respectively, on 28 October. In organizing the recaptured position, the Marines were hampered to some extent by a dense ground fog. Nevertheless, work still went ahead on these necessary tasks. Most of the Hook area was held by Company B; the western part of the 1/7 line, south of the Hook, was still manned by the platoon from Company A and one from Company C. The 1st Platoon of Company B quickly searched the retaken area of the MLR (except the caved in parts of the trenchline and bunkers, which were investigated later), but found no enemy soldiers. During the day, as Company B expanded its responsibility along the Marine main line, the platoons from A/1/7 and C/1/7 were relieved to rejoin their companies.[287] Supplies began to move in, once the permanency of the defense had been established.
