Bertie Wooster never went to war. He was a member of the idle rich .
Sergeant Bunter had been Major Peter Wimsey�s batman, or personal servant, during the Great War.
I think, from memory, that one or more of the manservants/butler's in the Dornford Yates' books had been their, the Pleydell/Chandos characters, Great War batmen.
