Provisional IRA Derry Brigade

The Derry Brigade of the Provisional Irish Republican Army (IRA) operated in the city of Derry, Northern Ireland, and its surroundings during the Troubles. The Derry Brigade was one of the most active groups in the IRA. == Origins == A small IRA battalion existed in Derry since the Troubles began, but it never had a steady number of volunteers until Bloody Sunday, which saw an influx of new recruits.
