The Maze Prison escape (known to Irish republicans as the Great Escape) took place on 25 September 1983 in County Antrim, Northern Ireland. HM Prison Maze (also known as Long Kesh) was a maximum security prison considered to be one of the most escape-proof prisons in Europe, and held prisoners convicted of taking part in armed paramilitary campaigns during the Troubles. In the biggest prison escape in British history, 38 Provisional Irish Republican Army (IRA) prisoner escaped from H-Block 7 (H7) of the prison. One prison officer died of a heart attack as a result of the escape and twenty others were injured, including two who were shot with guns that had been smuggled into the prison. The escape was a propaganda coup for the IRA, and a British government minister faced calls to resign.
