The Summary The X Corps Command Report gives a total of 9,675 battle casualties. Non battle casualties are not given for the entire corps. In the 1st Marine Division there were 3,561 battle casualties and 3,349 non battle casualties, mostly from cold. All five of the divisions involved at Chosin were either in action again or ready for action by the middle of January.

The Chinese had committed divisions in Korea, eighteen in the west, the twelve divisions on the 9th Army Group in the east. The exceptionally severe losses inflicted on the 9th Army Group kept all twelve of those divisions, forty per cent of the available Chinese forces, out of action until the very last week in March. Had those twelve divisions been available for the Chinese Third and Fourth Phase attacks in January and February their presence could have been decisive. The war might have ended then and there.

Conclusion It can be fairly said that the 1st Marine Division, with the 31st Infantry RCT and 41 Commando, supported by the 1st Marine Air Wing, the fast carriers of Task Force 77, various supporting Army communications companies and with an assist from the 5th Air Forces and the Third Infantry Division, played a decisive role at Chosin. We gave up the ground, but we may well have saved the war.
