There is a plaque on the wall of The Bingham Hall, King Street, Cirencester, that reads:-
"This building was used as a hospital for sick and wounded soldiers during The Great War.
It was manned by Gloucestershire Voluntary Aid Detachment No 84 and was open from 10 Dec 1914 to 31 Dec 1918 during which period 1852 cases were treated"
I have seen a picture of it in operation at this time in an "Alan Sutton" type book - a collection of old photographs- called something like "Cirencester at war".
