In support of the Marines on Hill 111 at 21:10 Wilton had ordered one company of the 1 DLI to occupy a reserve position on the left of 2 RAR, in the rear of the 1st Marine Division where they ultimately remained for the rest of the evening. A reserve company from 3 RAR was also embussed in order to be ready to respond to any emergency.[46] The Americans eventually drove off the Chinese probes after their artillery broke up the attack, but not before they were forced to abandon some of their forward positions.[46] With the attack likely only a diversionary effort, by 21:20 the bulk of the Chinese had begun to withdraw from Hill 111.[55] Meanwhile, the fighting on Hill 119 continued.[56] A heavy bombardment fell on the American positions at 21:00, followed by a second assault on Hill 119 by two Chinese companies which succeeded in penetrating the Marine perimeter.[53] Hand-to-hand combat developed across the forward trenches and in the ensuing fighting Company G was reduced to half-strength, while their ammunition began to run low.[55] Under pressure, by midnight the Americans were forced back another 1,500 metres (1,600yd) to the reverse slope.[49] 3 RAR was subsequently left exposed, with the forward Chinese elements moving to within 1,200 metres (1,300yd) of the battalion's A Echelon area. Almost surrounded, the position was at risk of becoming untenable.[57] At 00:15 Company I, 3rd Battalion, 1st Marines was ordered to reinforce Boulder City; they lost heavily after the Chinese intercepted a coded message and adjusted mortar and artillery fire onto the Marines as they approached the rear of Hill 119. In response the 11th Marine Artillery Regiment launched an intense counter-battery barrage.[55]
