When the attacks against Catholics known as the Belfast Pogrom erupted in July 1920, Tom Glennon was a 20-year old officer in the IRA. The next three years took him from brutal street fighting in Belfast to organizing a flying column in the Glens of Antrim, to a daring escape from captivity in the Curragh and then the viciousness of civil war in Donegal. This book not only tells the story of Tom Glennon's life, but also re-examines the mythology of the pogrom and questions Michael Collins' northern policy, asking: were the northern IRA the victims of a monstrous betrayal?
