Emergency Hospital In Byfleet

A Memory of New Haw.

My birth certificate states I was born 1940 in Byfleet in an Emergency Hospital. Does anyone know where that would have been. Have no idea why I was there except my mother (a Canadian) was returning home to Canada but was unable to do so because of the war. Perhaps she was stranded here or perhaps her husband had family in the area. Any help appreciated tracking down the exact place where this hospital would have been. Many thanks.
