The U.N. forces in the eastern part of North Korea, mostly U.S. Marines and Army infantry, were being pulled out of North Korea to the coast to Hungnam to leave North Korea. This was a fighting withdrawal, especially for the 14,000 Marines and infantry moving from Yudam-ni and Toko ri towards the Funchinlin Pass. They contended with at least four Chinese divisions and fought several pitched battles along the way to the coast, especially at Hill 1081 near Funchilin Pass. The last Marine senior officer to leave the pass was Chesty Puller.
