The ordinary methods of attempting escape were common enough in Newgate. Quarrying into the walls, breaking up floors, sawing through bars, and picking locks were frequent devices to gain release. In 1679 several prisoners picked out the stones of the prison walls, and seven who had been committed to Newgate for burglary escaped. No part of the prison was safe from attack, provided only the prisoners had leisure and were unobserved, both of which were almost a matter of course. Now it is a passage through the back of a chimney in a room occupied by the prisoner, now a hole through a wall into a house adjoining the prison. Extraordinary perseverance is displayed in dealing with uncompromising material. The meanest and seemingly most insufficient weapons served. Bars are sawn through like butter;[217:1] prisoners rid themselves of their irons as though they were old rags; one man takes a bar out of the chapel window, climbs through, and gets away over the house-tops; a gang working in association saw through eight bars, "each as thick as a man's wrist, leaving enough iron to keep the bars together, and fitting up the notches with dirt and iron-rust to prevent discovery;" but they are detected in time, and for proper security are all chained to the floor. Another lot are discovered "working with large iron crows," meaning to get through the floor. On this occasion "a great lot of saws, files, pins, and other tools" were found among the prisoners, plainly revealing the almost inconceivable license and carelessness prevailing. Again, two men under sentence of death found means to break out of Newgate "through walls six feet in thickness." They were brothers, and one of them being ill, he was out of humanity removed from his cell to an upper room, where the other was suffered to attend him. As they were both bricklayers by trade, they easily worked through the wall in a night, and so escaped. They were, however, retaken and hanged. The ease with which irons are slipped is shown repeatedly. One man having attempted to escape was as usual chained to the floor, yet he managed to get himself loose from an iron collar in which his neck was fastened and his hands extended. This man, when disengaged from the floor, had the resolution to wring the collar from his neck by fixing it between two of the bars of the gaol window, and thus by main strength he broke it in two. Others cut through their handcuffs and shackles two or three times in succession with the ease of the Davenport brothers freeing themselves from bonds.
