The Battles of Nakhang (16 February 1966–28 February 1969) were fought between Royalist forces and North Vietnamese invaders for control of the northern base of Nakhang, Laos. The Lima Site 36 airstrip at Nakhang was capable of handling aircraft up to the size of C-123 cargo carriers; its location and length made it a vital component of the Royalist defense. Lima Site 36 was the airhead for their guerrillas' movements and resupply, as well as a staging point for U.S. combat search and rescue helicopters. The People's Army of Vietnam (PAVN) first attacked Nakhang from 16–19 February 1966. They successfully overcame an aerial bombardment that razed both the village and the airfield's equipment. Though successful in this First Battle of Nakhang, the PAVN lost Nakhang again on 25 May 1966, as a Royalist counter-offensive attacked behind a screen of tactical air strikes. Once re-established there, the Royalist troops fanned out throughout northern Laos, even unto the border of the Democratic Republic of Vietnam. On 6 January 1967, the PAVN renewed their offensive for the Third Battle of Nakhang. Despite their taking advantage of an overcast they thought would prevent aerial support, they were defeated within two days by U.S. Air Force airstrikes. It was not until 28 February 1969 that the Vietnamese succeeded in capturing Lima Site 36 for good, with their surprise assault of the Fourth Battle of Nakhang. Background When the United States decided to underwrite the Royal Lao Government and the Royal Lao Armed Forces in 1953, it entered into what burgeoned into the Laotian Civil War. Its northerly location and its airfield made Nakhang, Laos a major base for the Royal Lao Government's military operations against the PAVN and the Pathet Lao (PL). The base itself menaced the Communist-held Route 6 supply line. The U.S. Air Force (USAF) stationed its Jolly Green Giants there, using it as a forward base for combat search and rescue for American air crews. The airstrip, with 700 unpaved meters of runway, could accept Air America C-123 Providers, as well as smaller craft. The airstrip's thinner air at 1,340 meters altitude and lack of navigational aids made it hazardous to use. Landings were a one-shot deal on final approach, with a hill at the northeast end of the strip blocking any pullouts for second attempts. Nevertheless, its vital forward location near the Communist stronghold of Houaphanh Province served as an air
