Hello, I stumbled on question whilst researching 298th US General Hospital, Stationed in Frenchay, Bristol. Side tracked as usual I though I would have a dig around for you.
What I have found about the 141st is that they were actually based in the Garrison Town of Devizes at the time your father was there. The 141st Gen Hospital was located in, Prince Maurice Barrack, London Road Devizes. 20 miles SW of Bath. Sadly the barracks were demolished in 1987. I am happy to help you in any possible should you want me to. Please feel free to email me
scrumpy1964@hotmail.co.uk I could look into possible millary museums in Devizes that may hold info as actually I live not far from Devizes. Also you would not be wasting your time going to the area as there is plenty to see and do.
Kind Regards Paul
