lnteresting to see the old Soyez cookers in the middle photo, in my time in the Army they were used to provide us with shaving water on exercise in the sub-zero German winter but I think they cooked stew from the Boer War onwards .
Sorry, I missed the Oswestry reference in the caption. Oswestry, probably Park Hall camp, was a Royal Artillery training camp, into the 60s. The marquees and the duckboards in the picture, suggest a temporary camp at that time.The mention of Devizes suggests an army connection though in July it was probably an outdoor tented camp and illustrated in the lower Oswestry photo. I get the feeling, from the crowd in the Snow Hill photo that some might be Territorial soldiers but there are quite a few women in the photo, maybe nurses or auxiliary nurses. Territorials were active before conscription.
