In April 1945, when the Bergen-Belsen concentration camp was surrendered and handed over to the British Army, Canadian forces arrived on scene to provide support, to bear witness, and to document the crimes. They were overwhelmed, understaffed, and left without adequate supplies, equipment, and medicine. Their encounters at the camp were haunting, transformative experiences that forever changed their lives. In Kingdom of Night, Mark Celinscak reveals the engagement of Canadian troops and other personnel at the Bergen-Belsen concentration camp. The book brings together a series of gripping, often deeply moving accounts that demonstrate the critical relief work carried out by Canadians who have been largely overlooked for more than seventy-five years. It outlines in both stark and moving detail what a cross-section of Canadians both said and did during the liberation efforts at one of the most notorious sites in Hitler's camp system. In addition, biographical overviews are presented for each Canadian featured in the book, not only highlighting some of their life-saving and humanitarian work, but also revealing what ultimately became of their lives after the war. Kingdom of Night depicts the gruelling efforts by those who assisted the victims of one of the greatest crimes in history.
