I've been reading some interesting accounts of this battle, in which overwhelming Chinese units destroyed a full battalion of the British Gloucestershire regiment, which had been ordered to hold the line to give other U.N. forces time to regroup.
All the sources I can find are from the United Nation's perspective. An example is here:

I am interested if any of you know where there are some (translated) accounts of this battle from the Chinese perspective. Thanks.
