Although the number of IRA killings fell slightly, the organisation carried out major attacks in Britain. Two attacks on a single day in July 1982 killed a total of eleven soldiers in two London parks, one of the highest military casualty tolls of the troubles. The first device was detonated as a troop of soldiers in full regalia made their way on horseback through Hyde Park on their way from their Knightsbridge barracks to Whitehall. Four soldiers died.
