Jack Sheppard's escapes from Newgate are historical, although much embellished by the novelist's art. Sheppard's success was really marvellous, but it may be explained to some extent by his indomitable pluck, his ingenuity, and his personal activity. As he was still quite a lad when he was hanged in 1724, he could have been barely twenty-two at the time of his escapes. In the proclamation for his apprehension after his second escape, he is described as about twenty-two years of age, five feet four inches in height, very slender, of a pale complexion, having an impediment or hesitation in his speech and wearing a butcher's blue frock with a greatcoat over it; a carpenter or house-joiner by trade. Twenty guineas reward was offered to any who might discover or apprehend him. From his early apprenticeship to a carpenter he had much skill and knowledge in the handling of tools. He first became celebrated as a prison-breaker by his escapes from the St. Giles's Round House and from the New Prison. His first escape, from the condemned hold of Newgate, where he lay under sentence of death, was more a proof of ingenuity than of prowess. The usual neglect of proper precautions allowed two female visitors to have access to him and to supply him with tools, probably a file and saw. With these he partly divided a spike on the top of the hatch which led from the condemned hold. Upon a second visit from his fair friends he broke off the spike, squeezed his head and shoulders through the opening, the women then pulling him through. How he got past the lodge where the turnkeys were carousing is not recorded, but it was probably in female disguise. His second escape, following his recapture, and a second sentence of death, was much more remarkable. This escape was, however, only rendered possible by the negligence of his keepers. They visited him at dinner-time, and after a careful examination of his irons, having satisfied themselves that he was quite secure, left him for the day. Released thus from all surveillance, time was all that Sheppard needed to effect his escape.
