On 25 May, after the UN Command had made its final offer at the
Panmunjom truce talks, the PVA artillery began to open up on the Nevada Complex. For the next three days the shells came in with growing frequency and PVA troop movements in the area increased. Acar secured artillery support from I Corps and the 1st Marine Division artillery, in addition to that which the 25th Division could provide, to counter the PVA concentrations. From the Marine
1st Tank Battalion, 34 tanks rolled into position to funnel direct fire support to the outposts. When the first attack came on the evening of 28 May, the Turkish units defending the outposts were well dug in and adequately armed. Barbed wire, trip flares, and mines were in place and automatic weapons sited to cover the enemy approach routes. There were 140 men at Vegas, 44 at Carson, 33 at Elko, 27 at Berlin, and 16 at East Berlin. Following an intense artillery and mortar preparation, the 120th Division sent four battalions forward, two to the east against the main objective, Vegas, one to the south against Carson and Elko, and one in a diversionary attack against Berlin and East Berlin. The diversionary attack was halted and broken off early in the evening. On Vegas the PVA succeeded in taking one small finger of the hill and clung tenaciously despite the heavy automatic weapons, small arms, artillery, and mortar fire at them. The Turks sent a reinforcing platoon in to bolster the defenders and it arrived in time to help throw back a three-pronged PVA assault on the outpost. After reorganizing, the PVA again sent a force estimated at two battalions to take the position. Ammunition began to run low and the Turkish 2nd Battalion commander sent another platoon accompanied by
Korean Service Corps personnel to resupply the embattled troops. After a brief respite in the fighting, the PVA tried again and this time they pushed through and hand-to-hand combat broke out in the trenches. Meanwhile, the PVA had added a second battalion to the assault on Carson and Elko and closed upon the Turkish positions. Bayonets and hand grenades were used freely as the Turks managed to repel the attack. The battalion commander sent an engineer platoon, then committed the rest of the engineer company to the defense of Carson. Shortly after midnight the pace slackened, but observers reported that a third PVA battalion was assembling to join in the assault. Fire support from the 1st Battalion of the Turkish force and the US
35th Infantry Regiment helped to disperse this reinforcing PVA battalion. As the night wore on, Elko held out against continuing PVA attacks, but the Turkish soldiers on Carson were being gradually eliminated. A few managed to slip over and join their comrades on Elko, but the majority died in the trenches and bunkers from PVA fire. By morning Carson belonged to the PVA. Convinced of the PVA determination to take the Nevada Complex, Williams placed the US 1st Battalion,
14th Infantry Regiment under Acar so that he could commit his reserves to the counterattack. However the PVA gradually gained control of the northwest portion of Vegas and Turkish casualties were increasing. In a desperate effort to blunt the PVA drive, the Turks began a counterattack to clear the hill and they slowly swept the PVA off of Vegas. Undaunted, the PVA regrouped and reinforced their offensive units, then came back again. The edged their way up Vegas and met the Turks, who refused to move. Late in the morning of 29 May, the Turks launched a four-platoon attack that cleared Vegas. The PVA in turn would not accept defeat and sent wave after wave of men against the Turkish positions, as casualties on both sides increased sharply. On Elko the battle continued throughout of the night of 28–29 May, as the PVA increased the pressure against the remnants of the Turkish force on the hill. Acar ordered Lieutenant colonel Carl E. Mann, the commander of the 1st Battalion, 14th Infantry, to send one of his companies to reinforce Elko and to retake Carson on the morning of 29 May. Company B approached Elko from the southeast, overran the PVA around the outpost, and secured the objective after a 25-minute fight. Using two platoons in the attack and two in the support roles, Company B then advanced west on Carson. Midway between Elko and Carson, the company began to receive heavy automatic weapons, artillery, and mortar fire, and the assault slowed, then halted. Withdrawing to Elko, Company B tried twice to gather momentum enough to break through the PVA wall of fire on Carson. Each time it failed and had to turn back. UN artillery, mortars and automatic weapons could not silence the PVA weapons nor dislodge the defenders. After the third assault ground to a halt, the PVA retaliated. Six times they crossed from Carson to Elko and on several occasions managed to advance within hand grenade range. Company B, supported by artillery, tank, mortar and automatic weapons fire, forced the PVA to break off the attack each time and Elko remained in UN possession. ==Aftermath==
