The start of the Irish Civil War was signalled by the artillery bombardment of the Four Courts in Dublin on 28 June 1922. A week later, the Four Courts was gutted and O'Connell Street was a smouldering ruin, but the anti-Treaty IRA was driven from the city. This book reveals the complete, shocking story of Ireland's capital during the ten-month guerilla war that followed - a ruthless and bitter cycle of execution, outrage and revenge. The strategy of the anti-Treaty forces is brought to the fore and Dorney's exacting research provides insight into how the city of Dublin operated under conditions of disorder and bloodshed: how civilians and guerilla fighters controlled the streets, how the patterns of IRA violence and National Army counter-insurgency alternated, and how the the pro-Treaty Squad emerged from Michael Collins' IRA Intelligence Department with devastating effect. The chaos of these years is brought to life in meticulous detail, revealing unsettling truths about the extreme actions taken by a burgeoning Irish Free State and its anti-Treaty opponents.
