It was a genuine emergency. The capital [London] was virtually undefended, the queen [Mary] in real danger of losing the crown she had won scarcely a year before. The imperial ambassador offered to request troops from the continent, while many of Mary’s councilors urged her to flee. Once again she was saved by her own courage. She refused the offer of foreign military support and refused also to leave London. Instead she put her faith in her subjects, and her fate in their hands. She went to the Guildhall, one of London’s gathering places, and in an impromptu speech addressed a gathering of citizens assembled by the lord mayor. She denounced the [rebel] Wyatt and his fellow conspirators, accusing them of wanting not only to prevent her marriage but to usurp the authority of the Crown and use it for their own narrow purposes. Scepter in hand, she declared her confidence that her subjects would never allow the rebels to prevail.
“As for this marriage,” she said, “ye shall understand that I enterprised not the doing thereof without the advice of all our Privy Council. Nor am I, I assure ye, so bent to my own will, or so affectionate, that for my own pleasure I would choose where I lust, or needs must have a husband. I have hitherto lived a maid [virgin]: and doubt nothing, but with God’s grace I am able to live so still. Certainly, did I think that this marriage were to the hurt of my subjects, or the impeachment of my royal estate, I would never consent thereunto. And I promise you, on the word of a queen, that if it shall not appear to the Lords and Commons in Parliament to be for the benefit of the whole realm, I will never marry while I live. Wherefore stand fast against the rebels, your enemies and mine. Fear them not, for I assure ye I fear them nothing at all.” … Mary departed to shouts of approval, and within hours more than twenty thousand men had volunteered to defend her and the city.
[The rebels attack London] and again cause a panic that only Mary’s resolution prevented from turning into a headlong flight of the entire court. Finally… the rebellion fell apart. …] For the second time in half a year Mary had been tested, as had the loyalty of the kingdom, and neither had been found wanting.
