Also, what about Burgoyne's army which by, the convention at Saratoga, was supposed to be paroled and returned to Britain. The proto-Marxist commissars of the Continental Congress violated that treaty and retained them in prison camps not any better than the ones you are discribing.
And there is also the proto-Marxist treatment of British Americans Loyal to the Crown, among them some of my ancestors, one of whom spent several months imprisoned in a salt mine, guilty of nothing more than his proper allegiance.
Nahh, don't go down that road as it will lead you places you do not want to go.
I thought you had given up firing off red herrings. The place is the Peninsula, the time is 1808-1814, the subject is the treatment of unoffending civilians by the British and French armies and the disciplinary measures both services had in place to punish those who dit not. Lets keep it within those bounds.
