 'Camp tokens' also circulated within the camp in place of money, being made of printed cardboard.A former IRA prisoner, Louis J. Walsh (a native of County Londonderry and later a judge in County Donegal), published a book in 1921 about his experiences in various institutions in Northern Ireland including a chapter about his time in Ballykinlar Camp which describes, amongst other things, having to march for three miles, handcuffed and carrying luggage, only to be placed in bare huts with nothing to sleep in except damp straw.He continues in a second chapter to describe how the prisoners set up their own 'Council' which then began to negotiate with the military authorities for better food and conditions within the camp.
