I have now received my relative's death certificate but it only contains the stamped entry 'Temporary Military Hospital Stoke upon Trent'.
I did find this on another forum:
The following is from Johnny Get Your Gun a personal narrative by John Tucker a Londoner serving with the Kensingtons.
We were put into a hospital train in the charge of a very fierce matron. We passed through London at night, much to my disappointment, and on to Newcastle-under-Lyme, near Stoke. I was taken by motor ambulance to Stoke War Hospital, actually at Newcastle.
The hospital set in neat grounds surrounded by a high wall, was originally the Stoke Workhouse.
My ward was a light, high ceilinged room, holding probably about 16 to 18 beds. On the right hand side of each bed there was a white cupboard. The iron bedsteads were covered with a clean white counterpain. The walls were dove grey distempered with white woodwork. The ward was immaculatley clean.
Also, I have been put in touch with someone who has more information on the hospital, so I hope this will take me to the next level of research.
Thanks
Clive
