Very interesting, but I had not heard that story before, although I had often heard personal stories, first hand from participants..members of the "Frozen Chosin", men I served with in the Army.
Curiously, my daughter-in-law's father and later he mother's second husband both served
as those among the Frozen Chosin. After that, both swore they never wanted to be that cold again.
Her bio Dad lived out his days near the Salton Sea, nearly on the Mexican border, while her step Dad & Mom have long lived around Phoenix !
