The Provisional Irish Republican Army (IRA) detonated two 6-pound (2.7-kilogram) gelignite bombs at two pubs in Guildford, Surrey, England on 5 October 1974. The pubs were targeted that evening because they were popular with British Army personnel stationed at Pirbright barracks. Four soldiers and one civilian were killed. Sixty-five people were wounded.
