Operation Eagle Pull
Operation Eagle Pull was the United States military evacuation by air of Phnom Penh, Cambodia, on 12 April 1975. At the beginning of April 1975, Phnom Penh, one of the last remaining strongholds of the Khmer Republic, was surrounded by the Khmer Rouge with the backing of the People's Republic of China (PRC) and totally dependent on aerial resupply through Pochentong Airport. With a Khmer Rouge victory imminent, the US government made contingency plans for the evacuation of US nationals and allied Cambodians by helicopter to ships in the Gulf of Thailand. Operation Eagle Pull took place on the morning of 12 April 1975 and was a tactical success carried out without any loss of life. Five days later the Khmer Republic collapsed and the Khmer Rouge occupied Phnom Penh.
At the beginning of 1975 the Khmer Republic, a United States-supported military government, controlled only the Phnom Penh area and a string of towns along the Mekong River that provided the crucial supply route for food and munitions coming upriver from South Vietnam. As part of their 1975 dry season offensive, rather than renewing their frontal attacks on Phnom Penh, the Khmer Rouge set out to cut off the crucial Mekong supply route. On 12 January 1975 the Khmer Rouge attacked Neak Luong, a key Khmer National Armed Forces (FANK) defensive outpost on the Mekong. On 27 January, seven vessels limped into Phnom Penh, the survivors of a 16-ship convoy that had come under attack over the 100 kilometres (62 mi) journey from the South Vietnamese border. On 3 February a convoy heading downriver hit naval mines laid by the Khmer Rouge at Phu My approximately 74 kilometres (46 mi) from Phnom Penh. The FANK naval branch, the Khmer National Navy (MNK), had mine-sweeping capability, but due to the Khmer Rouge control of the riverbanks mine-sweeping was impossible or at best extremely costly. The MNK had lost a quarter of its ships, and 70 percent of its sailors had been killed or wounded.
By 17 February, the Khmer Republic abandoned attempts to reopen the Mekong supply line. In future, all supplies for Phnom Penh would have to come in by air to Pochentong Airport. The United States quickly mobilised an airlift of food, fuel and ammunition into Phnom Penh, but as US support for the Khmer Republic was limited by the Case–Church Amendment, BirdAir, a company under contract to the US government, controlled the airlift with a mixed fleet of C-130 and DC-8 planes, flying 20 times a day into Pochentong.
On 5 March, Khmer Rouge artillery at Toul Leap, north-west of Phnom Penh, shelled Pochentong Airport, but FANK troops recaptured Toul Leap on 15 March and ended the shelling. Khmer Rouge forces continued to close in on the north and west of the city and were soon able to fire on Pochentong again. On 22 March rockets hit two supply aircraft, forcing the US embassy to announce on 23 March a suspension of the airlift until the security situation improved. The embassy, realizing that the Khmer Republic would soon collapse without supplies, reversed the suspension on 24 March and increased the number of aircraft available for the airlift. On 1 April, the Khmer Rouge overran Neak Luong and Ban-am, the last remaining FANK positions on the Mekong. The Khmer Rouge could now concentrate all their forces on Phnom Penh. Premier Lon Nol resigned that day and went into exile; the final collapse of the Khmer Republic was imminent.
The evacuation plan was developed and refined by the US Military as Khmer Rouge forces closed in on Phnom Penh, starting as early as 1973. On 27 June 1973 the Seventh Air Force published Contingency Plan 5060C "Eagle Pull" covering the evacuation of Phnom Penh. Conplan 5060C had three options:
Option 3 was later revised to provide for the use of USMC helicopters together with USAF helicopters and C-130 Airborne Mission Command based in Thailand, and for the ground security force to be made up of marines rather than air force security police. The LZs were to be adjacent to the US Embassy in Phnom Penh.
On 6 January 1975, CINCPAC placed the 31st Marine Amphibious Unit on 96-hour alert to move the evacuation fleet into position off Kampong Som (previously Sihanoukville) in the Gulf of Thailand for the implementation of Operation Eagle Pull. On 6 February the reaction time was reduced to 48 hours, meaning that the evacuation fleet had to maintain a 48-hour cruising radius from Kampong Som. This was further reduced on 28 February to 24 hours, effectively meaning that the fleet had to remain within the Gulf of Thailand.
On 21 March the Embassy predicted there would be 3,600 evacuees, far exceeding the original estimate of approximately 400. This necessitated the development of a new evacuation plan whereby Marines would secure Pochentong Airport, while helicopters would ferry evacuees from central Phnom Penh to Pochentong from where they would be flown on C-130 planes to Thailand. However, this plan was quickly overtaken by events as the supply C-130s coming into Pochentong were used for evacuees on the return journey, quickly reducing the number of evacuees that would need to be moved in a final evacuation.
