I don't think we had US service men stationed locally WW1, yes for WW2.
Our local hospital.
"The 67th General Hospital was authorised on 3 March 1941, during the Second World War, and activated 1 September 1942 as an American Army Hospital and occupied by the U.S. Army Medical Corps.
After the war, it continued in use as a Ministry of Pensions Hospital and only became a General Hospital within the National Health Service in 1951."
