George Lyon (1761–22 April 1815) was a gentleman highwayman in England.
Lyon was born in Upholland, Lancashire, to a poor family. His name was George Lyon - not George Lyons as some historians wrongly believe.
George Lyon's one major feat as a highwayman was to hold up the Liverpool mail coach. With his accomplices, who have been unknown since, he planned the robbery at the Legs of Man public house in Wigan. They then persuaded the ostler at the Bull's Head Inn in Upholland to lend them horses for a few hours. They held up the Liverpool mail coach at nearby Tawd Vale on the River Tawd, firing two shots and forcing the driver to pull up so that they could rob the passengers. The gang then returned to the Bull's Head, and when the robbed coach later arrived at the inn, Lyon and his accomplices had an alibi as people had seen them in the pub earlier in the afternoon.
In addition to this robbery, Lyon was a habitual thief, and had been transported to one of the colonies for some years before returning to Upholland.
Local legend suggests Lyon was inept at highway robbery. It is said that he decided to hold up the coach taking the wages to a local coal mine but on the day of his intended crime it was pouring with rain. He stood out to stop the coach too early and the rain ruined the gunpowder in his pistol - the coach's driver, perhaps realising this, simply coaxed the horses into a run and soaked Lyon with muddy water as they flew past.
George Lyon was 54 when he was executed in Lancaster by hanging for robbery, as the last highwayman to be hanged there. Sentence was passed on Saturday 8 April 1815 along with two accomplices, Houghton and Bennett.
A fourth accomplice was Edward Ford, who had been working as a painter at Walmsley House, where the last robbery took place and for which Lyon and his accomplices were eventually indicted. Ford had suggested robbing the house to Lyon, and had himself taken part in some 17 previous robberies, but because he turned King's evidence he was spared the capital sentence. The execution of Lyon, Houghton, and Bennett, took place just before noon on Saturday 22 April 1815 - the year of the Battle of Waterloo.
