TNA file BT 168/65. The covering note gives the date as 6 June 1945. Note that this is Base Camps only, not Working Camps. I am frankly having trouble discriminating at this stage between the two as it is clear prisoners by this stage were in employment in civilian work operating from Base Camps. I suspect that the name was retained to indicate what were called 'ardent Nazis' retained in Base Camps. Elsewhere I have stated Germans were all in camps numbered less than 200 up to the war's end. I think this shows that to be a fairly accurate statement, but I would be interested if anyone had found German prisoners in camps at this time numbered 500+. I think these being the numbers of the Pioneer Corps Guard Companies. I am fairly sure there were Italians in camps numbered 500+.
