The forgotten Hagaru-ri airlift
Official period caption: “Astonished Marines of the 5th and 7th Regiments, who hurled back a surprise onslaught by three Chinese communist divisions, hear that they are to withdraw! Ca. December 1950.”
After four days of violent combat in late November 1950 against the PRC’s fresh 59th, 79th, and 89th divisions, the 5th and 7th Marines began a fighting withdrawal to Hagaru-ri, the division’s forward operating base, some 14 miles south, with an ultimate evacuation by sea at Hungnam, another very cold and hard 78 miles away.
Joined in Hagaru-ri by the Army’s badly mauled 31st Regimental Combat Team, one of the first large American aeromedical evacuations then took place with wounded removed by USAF and Marine C-47s and C-54s, as well as by Stinson OY-1 liaison aircraft, and Sikorsky HO3S-1 helicopters of Marine Observation Squadron (VMO) 6.
By the end of 5 December, the last full day of the Hagaru-ri airlift before the troops bugged out for Hungnam, an eye-popping 4,369 wounded Marines and Soldiers had been evacuated by the Combat Cargo Command in six days.

The battered 1st Marine Division reached the port of Hungnam on 11 December, and evacuation by 193 assembled Task Force 90 ships commenced through Christmas Eve, by which time some 100,000 UN troops and another 98,000 Nork refugees had been taken off by sealift.

They call it “the Forgotten War” and it is good that your site reminds people what remarkable events happened there. I was raised on army bases in Canada in the 50s and 60s; some of our neighbours had served there.
