The Bowmanville boys' school had been quickly turned into a POW camp by surrounding the existing school buildings with a barbed wire fence. The facility, which had been designed to house 300 boys, was cramped and undersized for grown men. Two fences with electric lights every twelve feet and nine guard towers surrounded the site. The fence had sixty miles of barbed wire looped around the small perimeter. Lieutenant Colonel R.O. Bull M.C. had a support staff plus the Veterans Guard of Canada, consisting of nine officers and 239 other ranks under his command to guard the prisoners.
