The Duke of Suffolk, father of Lady Jane Grey, with his brothers, the Lords John and Thomas Grey, entered into the plot. Courtenay, dazzled by the prospect of a crown and the hope of wedding Elizabeth, engaged to put himself at the head of the rebels, but, as the hour approached, he shrunk from the perilous enterprise, and confessed the design to Gardiner. Thus betrayed, the conspirators were obliged to precipitate their plans, which were not intended to have been put into execution till the arrival of Philip. A rising was attempted at Exeter by Sir Peter Carew, but met with little support, and was quickly suppressed by the Earl of Bedford. Several of the conspirators were apprehended, and Carew fled to France. The Duke of Suffolk and his brothers were equally unfortunate, and after a futile attempt to make a stand in Leicestershire, were arrested and lodged in the Tower. A far more successful attempt was made by Sir Thomas Wyat in Kent. Speedily rallying a large force round his standard, he marched towards London, and defeated the veteran Duke of Norfolk, who was sent to oppose him. The rebellion had now assumed a formidable aspect. Wyat was in Southwark, at the head of fifteen thousand men, menacing the metropolis, in which he expected to find an immense number of supporters. Undismayed by the danger, the Queen repaired to Guildhall, addressed the Lord Mayor and citizens in language so stirring and energetic, that they promised to defend her to the last; and when Wyat, designing to take the city by assault, was prevented by the Tower batteries from crossing London Bridge, but subsequently effected a passage higher up the river, and so approached the capital from the west, his partisans became alarmed at the vigorous preparations made for their reception, and began to desert him. An engagement took place at Charing Cross, which resulted in the defeat of the insurgents, and though Wyat gallantly fought his way with a few followers to Ludgate, none rose to join him, and he was compelled to retreat to Temple Bar, where he surrendered to Sir Maurice Berkeley, by whom he was taken to the Tower.
