Following Éamon de Valera’s departure to the United States Michael Collins was finally in a position where he could begin his war against British Intelligence. It was clear that the Irish Volunteers could not hope to win in a fight against the British military but Collins believed that wiping out their spy network in Ireland would give the Volunteers a chance. In July he orders Dick McKee and Mick McDonnell of the Dublin Brigade to assemble a group of men for “special duties”, the first of which is the killing of a DMP Detective Sergeant. This group will later go on to form the Squad.
