He boarded the train at the driver change-over at Crewe station, his home town, in Cheshire, on the train's journey to London Euston station, a journey that would take the train through Buckinghamshire, where the gang of robbers were waiting for it. There, Mills approached the set of two signals that were normally both green. The robbers had, however, changed the first set of signals to yellow, warning the driver to slow down, and the second set to red, telling the driver to stop the train. He stopped, and soon after the robbers launched their robbery. When they got into the cab of the locomotive, they attacked Mills with an iron bar, and he suffered a black eye and facial bruising. He was handcuffed to the train's secondman, David Whitby, in the locomotive's engine compartment. After the robbery, Mills was taken to the Royal Buckinghamshire Hospital in Aylesbury, where he and his second man had to wait for a free police officer to remove the handcuffs.
Aftermath
Mills, who was 58 at the time of the robbery, never fully recovered from his injuries. He returned to work inMay 1964, and worked for 18 months on light duties. He was then on sick leave from November 1965 until December 1966 with shingles. He returned for one last year in work for 1967, retiring for good at Christmas, with two and a half months off sick that year. Jack Mills sustained severe brain damage from blows to the head. He never recovered and suffered until his death.
Death
When Ronnie Biggs' wife Charmian Biggs' story was told in the Sunday Mirror, it was revealed by rival papers that she had been paid £65,000, dwarfing the £250 compensation that Mills had received. The Daily Mail then launched an appeal on his behalf that raised £34,000, which enabled Mills to move into a more comfortable house in Crewe. Mills died in February 1970 shortly after moving. He died of chronic lymphocytic leukaemia, with a further complication of bronchial pneumonia. The West Cheshire Coroner concluded that there was no reason to hold an inquest and that while he was aware that Mills had been injured in the incident, there was no connection as far as he was concerned.
Mills' assailant
The identity of the train robber who assaulted Mills has been the subject of some debate, but most sources agree that Mills' assailant was one of three members of the gang who were never identified. He was referred to as "Mr Three" by Ronnie Biggs, and "Alf Thomas" by Piers Paul Read and Bruce Reynolds. Where all accounts agree, is that Gordon Goody made Mills drive the train after the failure of the robbers' substitute driver, and that Charlie Wilson told Mills not to worry and that he would not be harmed and ensured he was left alone after that. Williams claims in his 1973 book No Fixed Address: In a widely discredited version of the attack on Mills contained in The Train Robbers, by Piers Paul Read, the assailant is given as Buster Edwards. Edwards is listed as the assailant of both Whitby and Mills, although the description of the attack seems implausible given it does not match the description given at the trial and seems to have one train robber doing the entire assault by himself while the rest of the gang was idle. Reynolds dismisses the claim by Read, as the publishers at the time wanted the name of the perpetrator before they would do a deal, therefore Buster offered himself up as the villain. Buster Edwards was the member of the gang who ambushed David Whitby, Mills' assistant. At the same time the rest of the gang were moving into position with Roy James, "Bill "Flossy" Jennings", and Jimmy White uncoupling the carriages and the 'heavies' ambushing the cab of the locomotive itself. Bruce Reynolds claims the person responsible was a friend of Jimmy White, who they had recruited for a previous job to be extra muscle. Reynolds himself was not at the train site as he was the spotter at the Ledburn road rail bridge and met the gang at the rendezvous point at Bridego Bridge after Mills was forced by Goody to drive the train. He describes "Alf Thomas" as "a big old boy, very reliable, and would have been useful for the money train" "because he had the muscle to disable the police cars by tipping them over before we sprayed them with fuller's earth and compressed air." On 12 November 2012, James 'Big Jim' Hussey admitted a few hours before his death to having carried out the attack on Mills. It has been conjectured that the confession was intended to divert suspicion from the surviving train robbers.
