While the Reno and Vegas relief units were pinned down at the Block, the situation at the outposts remained critical. Throughout the night new waves of Communist soldiers poured out from their positions behind Chogum-ni, Hills 31 and 31D. When a company of enemy troops were observed at 2100 massing near Chogum-ni for a new assault, it was quickly disposed of by Marine artillery and Company A tankers. At Reno where the immediate situation was the most grim, a message at 2145 reported the enemy still in the trenches, trying to dig down into the cave while the Marines were attempting to work their way out by hand. The final report from Reno received late that night, about 2300, was weak and could not be understood. At Vegas, meanwhile, communications failure continued to complicate defensive measures at the outpost. Because of this, on the order of regimental commander, Colonel Walt, operational control had been transferred, at 2119, from 1/5 to 3/5. Three minutes before midnight all contact with Vegas was lost. As with Reno, reinforcements sent out with the mission of buttressing the Vegas detachment had been delayed. When it became evident that the Company D platoon had been pinned down at the Block, a platoon from E/2/5 jumped off at 2323 for the Vegas position. Shored up to reinforced company strength, the composite unit at the Block had prepared to move on for the ultimate relief of C/1/5 forces at Reno. Chinese firepower and troops continued to lash the position, however. There seemed to be no limit to the number of reserve troops the enemy could throw into the attack. At 2157, two Chinese platoons had hit the Block. Twenty minutes later, another two platoons struck. By 2300, the Marines had repulsed three attacks, numbering more than 200 troops, amid a continuing withering avalanche of bullets and shells. Shortly before midnight, a full enemy company had deployed south from Reno to the Block, but had been largely cut down by friendly 90mm tank fire and VT rounds from 1/11. Reinforced and reorganized, the Marines again prepared for a counterpunch on Reno. By midnight on the 26th, after five blistering hours of battle--to develop into five days of intense conflict and continuing counterattacks--the early efforts of the enemy were partly successful. Two of the Nevada Hill outposts had fallen, and Marine attempts to strengthen them were initially being thwarted by Chinese troops that had overflowed the Block and southward toward the MLR. COP Carson was holding. But the enemy was in control of Reno and Vegas and was using the Reno position to mass troops and firepower to further brace his continuing assault on Vegas.
