On the same day as the Declaration of Independence was issued, two members of the Royal Irish Constabulary (RIC) escorting a cartload of gelignite were killed in the Tipperary Soloheadbeg Ambush, carried out by members of the 3rd Tipperary Brigade of the Irish Volunteers, led by Dan Breen and Seán Treacy. This ambush had not been ordered by the Dáil, but the course of events soon drove the Dáil to recognise the Volunteers as the army of the Irish Republic, and so the Soloheadbeg incident became the opening incident of the undeclared Anglo-Irish War between the Volunteers and Great Britain. Breen later recalled: "Treacy had stated to me that the only way of starting a war was to kill someone, so we intended to kill some of the police."
