On 22 February 1972 , Aldershot experienced one of the worst UK mainland IRA attacks of the time . Seven people , all civilian support staff , including cooks , cleaners , and a Catholic priest , were killed and 19 people were injured , in a car bomb attack on the 16th Parachute Brigade headquarters mess at Aldershot garrison . This blast was later claimed , by the Official IRA , as revenge for the shootings in Derry that came to be known as Bloody Sunday . Until then , the military town had been open-plan , but the attack led to immediate action to secure military property by erecting security fences topped with barbed wire . Other security measures , including armed patrols were also implemented
