having been ordered off their bus by an armed republican gang, which called itself the South Armagh Republican Action Force. One man survived despite being shot 18 times, leaving ten fatalities. These killings were reportedly in retaliation to a loyalist double shooting attack against the Reavey and O'Dowd families the previous night. The violence continued through the rest of the 1970s. This included a series of attacks in Southern England in 1974 and 1975 by Provisional IRA active service unit the Balcombe Street Gang. The British Government reinstated the ban against the UVF in October 1975, making it once more an illegal organisation. The Provisional IRA's December 1974 ceasefire officially ended in January 1976, although it carried out several attacks in 1975. It had lost the hope that it had felt in the early 1970s that it could force a rapid British withdrawal from Northern Ireland, and instead developed a strategy known as the "Long War", which involved a less intense but more sustained campaign of violence that could continue indefinitely. The Official IRA ceasefire of 1972, however, became permanent, and the "Official" movement eventually evolved into the Workers' Party, which rejected violence completely. However, a splinter from the "Officials"—the Irish National Liberation Army—continued a campaign of violence in 1974. Late 1970s By the late 1970s, war-weariness was visible in both communities. One sign of this was the formation of the Peace People, which won the Nobel Peace Prize in 1976. The Peace People organised large demonstrations calling for an end to paramilitary violence. Their campaign lost momentum, however, after they appealed to the nationalist community to provide information on the IRA to security forces. In February 1978, the IRA bombed La Mon, a hotel restaurant in Comber, County Down. The decade ended with a double attack by the IRA against the British. On 27 August 1979, Lord Mountbatten while on holiday in Mullaghmore, County Sligo, was killed by a bomb planted on board his boat. Three other people were also killed: Lady Brabourne, the elderly mother of Mountbatten's son-in-law; and two teenagers, a grandson of Mountbatten and a local boatman. That same day, eighteen British soldiers, mostly members of the Parachute Regiment, were killed by two remote-controlled bombs in the Warrenpoint ambush at Narrow Water Castle, near Warrenpoint, County Down. It was the British Army's largest loss of life in a single incident in Operation Banner. Successive British Governments,
