Attacks on high-profile political and military targets remained a priority for the IRA. The Chelsea Barracks bombing in London in October 1981 killed two civilians and injured twenty-three soldiers; a week later the IRA struck again in London by an assassination attempt on Lieutenant General Steuart Pringle, the Commandant General Royal Marines. Attacks on military targets in England continued with the Hyde Park and Regent's Park bombings in July 1982, which killed eleven soldiers and injured over fifty people including civilians. In October 1984 they carried out the Brighton hotel bombing, an assassination attempt on British prime minister Margaret Thatcher, whom they blamed for the deaths of the ten hunger strikers. The bombing killed five members of the Conservative Party attending a party conference including MP Anthony Berry, with Thatcher narrowly escaping death. A planned escalation of the England bombing campaign in 1985 was prevented when six IRA volunteers, including Martina Anderson and the Brighton bomber Patrick Magee, were arrested in Glasgow. Plans for a major escalation of the campaign in the late 1980s were cancelled after a ship carrying 150 tonnes of weapons donated by Libya was seized off the coast of France. The plans, modelled on the Tet Offensive during the Vietnam War, relied on the element of surprise which was lost when the ship's captain informed French authorities of four earlier shipments of weapons, which allowed the British Army to deploy appropriate countermeasures. In 1987 the IRA began attacking British military targets in mainland Europe, beginning with the Rheindahlen bombing, which was followed by approximately twenty other gun and bomb attacks aimed at British Armed Forces personnel and bases between 1988 and 1990.
