The battle exacerbated inter-service hostility, the Marines blaming the US Army and its leadership for the failure. The collapse of the army units fighting on the east of the reservoir was regarded as shameful, and for many years afterwards their role in the battle was largely ignored. Later studies concluded that Task Force MacLean/Faith had held off for five days a significantly larger force than previously thought and that their stand was a significant factor in the Marines' survival. This was eventually recognized in September 1999 when, for its actions at Chosin, Task Force Faith was awarded the Presidential Unit Citation, an award that General Smith blocked when it was first proposed in 1952.
