Our history books must differ on this subject. Mine say the British took off anyone.No, no, no, the Brits took off DESERTERS, not yankees. Must remember that the British were just taking off their deserters, prisoners. Much like what the US is doing now, going into other places and taking "bad people".
Incidentally, I once saw this really dramatic chart which shows Napolean's march to and from Russia as a line that starts out very thick and ends up a thin fiber. Very powerful.
