On November 21, 1950 US Army 7th Division elements of X Corps occupied Hyesanjin and surrounding ground to the banks of the Yalu River.

General MacArthur sent a message to the X Corps commander General Almond:

Heartiest congratulations, Ned, and tell Dave Barr that the 7th Division hit the jackpot.

General Almond added his own congratulations to Barr: “The fact that only twenty days ago this division landed amphibiously over the beaches at Iwon and advanced 200 miles over tortuous mountain terrain and fought successfully against a determined foe in subzero weather will be recorded in history as an outstanding military achievement.”
