Surprise gave the attack an opening advantage and rapid progress was made at first along the main ridgeline leading west to Hill 812. Then Fox Company was stopped by the crossfire from the head of the “T.” Easy Company passed through at 0830 to continue the assault, reinforced by a platoon of Fox Company that had become Separated from its parent unit, although it kept in touch by radio.
An air strike was called but did not materialize. After waiting for it in vain, Easy Company drove toward the summit with the support of artillery and mortars.
Two hours after passing through Fox Company, the attackers had advanced only about a hundred yards against the NKPA crossfire. At 1100, Lieutenant Colonel Stiff ordered an all-out drive for the objective, following a preliminary barrage of everything that could be thrown at the enemy—artillery, 75mm recoilless, rockets, and 81mm and 4.2″ mortars. As soon as the bombardment lifted, Easy Company was to drive straight ahead along the ridgeline while the 2d Platoon of Fox Company made a flank attack.
This maneuver turned the trick. The blow on the flank took the enemy by surprise, and in just 36 minutes the assault troops were on the summit after a hard fight at close quarters with automatic weapons and grenades. Since regimental orders had specified “before nightfall,” Objective DOG had been seized ahead of schedule.
With scarcely a pause, Easy Company continued along the ridgeline leading west from Hill 812 toward Hill 980. Remarkably fast progress was made against an enemy who appeared to be thrown off balance. Permission was asked to seize Hill 980. The regimental commander refused because of instructions from Division to the effect that this position could not be defended while the enemy remained in possession of Hill 1052, the key terrain feature. Easy Company was directed to withdraw 600 yards toward Hill 812.
Late in the evening of 17 September, Colonel Weede directed his two assault battalions to consolidate on the best ground in their present locations and prepare to hold a defensive line.
When the brakes were put on the attack, 3/5 was strung out over a wide area to the north of Hill 751. This battalion was not tied in with 2/5, which occupied positions coordinated for the defense of Hill 812—Easy Company to the west, on the ridgeline leading to 980; Dog and Weapons Company to the south, protecting the left flank; and Fox Company to the east.
Both Easy and Fox Companies were under fire from Hills 980 and 1052, and daytime movement on 812 was restricted to the northern slope. Even so, sniping shots from well aimed North Korean 76mm mountain guns inflicted a number of casualties.
The Struggle for the “Rock”
An abrupt change in the enemy’s strategy became evident throughout these September operations. Where he had previously contented himself with an elastic defense, every position was now bitterly fought for and held to the last man. When it was lost, counterattacks were launched in efforts to regain it.
