She gave birth to a daughter, Susannah, who died a year later. Snell borrowed a male suit from her brother-in-law James Gray, assumed his name, and began to search for Summes, who had abandoned her while she was pregnant with his child. She later learned that her husband had been executed for murder. According to her account, following the death of her daughter, on 23 November 1745, she joined John Guise's regiment, the 6th Regiment of Foot, in the army of the Duke of Cumberland against Bonnie Prince Charlie
She deserted when her sergeant gave her 500 lashes and moved to Portsmouth and joined the Marines. She boarded the ship Swallow at Portsmouth. The ship sailed to Lisbon. Her unit was about to invade Mauritius, but the attack was called off. Her unit then sailed to India.
In August 1748, her unit was sent to an expedition to capture the French colony of Pondicherry in India. Later, she also fought in the battle in Devicottail in June 1749. She was wounded eleven times to the legs.
In 1750, her unit returned to Britain and traveled from Portsmouth to London, where she revealed her sex to her shipmates on 2 June. She petitioned the Duke of Cumberland, the head of the army, for her pension. She also sold her story to London publisher Robert Walker, who published her account, The Female Soldier, in two different editions. She also began to appear on stage in her uniform presenting military drills and singing songs. Three painters painted her portrait in her uniform and The Gentleman's Magazine reported her claims. She was honorably discharged and the Royal Hospital, Chelsea officially recognized Snell's military service in November and granted her a pension in 1750 (increased in 1785), a rare thing in those days.
Hannah retired to Wapping and began to keep a pub named The Female Warrior (or The Widow in Masquerade, accounts disagree) but it did not last long. By the mid-1750s, she was living in Newbury in Berkshire. In 1759, she married Richard Eyles there, with whom she had two children. In 1772, she married Richard Habgood of Welford, also in Berkshire, and the two moved to the Midlands. In 1785, she was living with her son George Spence Eyles, a clerk, on Church Street, Stoke Newington.
In 1791, her mental condition suddenly worsened. She was admitted to Bethlem Hospital on 20 August. She died on 8 February 1792.
