The Nevada Complex was located on low hills, approximately 10 miles (16 km) northeast of Panmunjom and the same distance north of Munsan-ni.

[3]: 462 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.

Barbed wire, trip flares, and mines were in place and automatic weapons sited to cover the enemy approach routes.

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.

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.

As the night wore on, Elko held out against continuing PVA attacks, but the Turkish soldiers on Carson were being gradually eliminated.

[3]: 463 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.

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.

Midway between Elko and Carson, the company began to receive heavy automatic weapons, artillery, and mortar fire, and the assault slowed, then halted.

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.

[3]: 463–4 By mid-afternoon on 29 May, Williams and I Corps Commander Lieutenant general Bruce C. Clarke evidently felt that the Chinese intended to remain on the offensive until the outposts were taken.

Over 117,000 rounds of artillery fire and 67 close air support missions had aided the UN ground units in withstanding the determined assaults of the PVA.

Undeterred apparently by the casualties incurred, the Chinese now seemed ready to use personnel and carefully hoarded supplies of ammunition with a free hand as the negotiations entered the final phase.
