Referred to by the court as Jane Dudley, wife of Guildford, Jane was charged with high treason, as were her husband, two of his brothers, and the former Archbishop of Canterbury, Thomas Cranmer. Their trial, by a special commission, took place on 13 November 1553, at Guildhall in the City of London. The commission was chaired by Sir Thomas White, Lord Mayor of London, and Thomas Howard, 3rd Duke of Norfolk. Other members included Edward Stanley, 3rd Earl of Derby and John Bourchier, 2nd Earl of Bath. As was to be expected, all defendants were found guilty and sentenced to death. Jane's guilt, of having treacherously assumed the title and the power of the monarch, was evidenced by a number of documents she had signed as "Jane the Quene". Her sentence was to "be burned alive on Tower Hill or beheaded as the Queen pleases" (burning was the traditional English punishment for treason committed by women). The imperial ambassador reported to Charles V, Holy Roman Emperor, that her life was to be spared.
