 Although Walker did not cancel the Home @-@ by @-@ Christmas Offensive on November 27 , Keiser ordered his division to withdraw to Kujang @-@ dong . Before Keiser 's order was complete on November 28 , Walker instructed Major General John B. Coulter of the IX Corps to set up a new defensive line at Kunu @-@ ri — 20 mi ( 32 km ) south of the US 2nd Infantry Division . Full scale retreat of the US 2nd Infantry Division started on the night of November 27 , with the Chinese attacking everywhere against the Americans . As the division 's convoy tried to move south , they were met with machine gun and mortar fire from numerous Chinese roadblocks in the rear . Chinese bazooka teams had also knocked out several vehicles while others were trying to swarm the tanks and to lob grenades into the hatch . With some losses , the US 2nd Infantry Division broke through the PVA 118th Division 's blockade and arrived at Kunu @-@ ri on the night of November 28 .
