Squires, charged with assault and theft, and Wells, with "well-knowing" what her accomplice had done, were tried on 21 February at the Session House of the Old Bailey. The Lord Mayor of London Sir Crisp Gascoyne presided over the court with a panel of other justices, including Martin Wright (Justice of the King's Bench), Nathaniel Gundry (Justice of the Common Pleas), Richard Adams (Baron of the Exchequer since 1753; formerly Recorder of London), and William Moreton (appointed Recorder of London in 1753). The gallery was packed with interested spectators. The charge of theft was extremely serious; the value of Canning's stays (about 10 shillings) meant that if she was found guilty, Squires would almost certainly be hanged at the Tyburn Tree.
