The Carrowkennedy ambush was an ambush carried out by the Irish Republican Army (IRA) on 2 June 1921, during the Irish War of Independence. An IRA flying column, commanded by Michael Kilroy, ambushed a mobile patrol of the Royal Irish Constabulary including Black and Tans recruits at Carrowkennedy, near Westport, County Mayo. It resulted in the deaths of eight of the RIC, including some who were killed by their own rifle grenade. After two hours the RIC surrendered and their weaponry and ammunition were seized by the IRA.
