The Great Train Robbery was the robbery of £2.6 million from a Royal Mail train heading from Glasgow to London on the West Coast Main Line in the early hours of 8 August 1963, at Bridego Railway Bridge, Ledburn, near Mentmore in Buckinghamshire, England.After tampering with the lineside signals to bring the train to a halt, a gang of 15, led by Bruce Reynolds, attacked the train. Other gang members included Gordon Goody, Buster Edwards, Charlie Wilson, Roy James, John Daly, Jimmy White, Ronnie Biggs, Tommy Wisbey, Jim Hussey, Bob Welch and Roger Cordrey, as well as three men known only as numbers "1", "2" and "3", two of whom later turned out to be Harry Smith and Danny Pembroke. A 16th man, an unnamed retired train driver, was also present.With careful planning based on inside information from an individual known as "The Ulsterman", named (erroneously) as Patrick McKenna in 2014, the robbers escaped with over £2.6 million (equivalent to £56 million today). The bulk of the stolen money was never recovered. Though the gang did not use any firearms, Jack Mills, the train driver, was beaten over the head with a metal bar. Mills suffered serious head injuries. After his partial recovery, he returned to work doing light duties. He retired in 1967. Mills died in 1970 due to an unrelated illness. He never overcame the trauma from the robbery. After the robbery, the gang hid at Leatherslade Farm. After the police found this hideout, incriminating evidence led to the eventual arrest and conviction of most of the gang. The ringleaders were sentenced to thirty years in jail.
