All Kent and Sussex rose to join Cade, who advanced to Blackheath, and boldly sent in his demands to the king. Many of the Londoners favoured him, and the gates of the city opened at his approach. For a moment he was in possession of the capital. Smiting London Stone with his drawn sword, he cried, "Now is Mortimer Lord of London." He exercised his lordship by seizing and beheading Lord Say, the treasurer, and Crowmere, Sheriff of Kent, two friends of Suffolk. He would have done the same with others of the king's servants if he could have caught them. But this violence and the plundering of houses and shops by his disorderly followers provoked the citizens, who closed the gates and came to blows with the rebels. The king brought up armed retainers to help the Londoners, and after a space Cade's men dispersed on the promise of a royal pardon. Their leader, however, refused to take advantage of the amnesty, fled to the woods, and was tracked down and slain a few weeks later. His rising had failed mainly because he was a mere adventurer, and could not keep his followers in order. [Sidenote: =The Dukes of York and Somerset.=] But hardly had Cade fallen, when the Duke of York, whose name he had been using so freely, suddenly came over in person from Ireland to put himself at the head of the opposition. His first demand was a change of ministry, and especially the dismissal of Somerset, who had now returned from Normandy, and had been placed at the head of the king's council, as if he had come back covered with glory instead of with dishonour. But Henry and his queen were set on keeping their cousin of Beaufort in power, and York had for the time to hold back, lest he should be accused of open treason. [Sidenote: =Loss of Guienne.--The Duke of York takes up arms.=] His opportunity of speaking with effect was not long in coming. In 1451 the French attached Guienne, the last province over-sea where the English banner was still displayed. The loyal Gascons made a stout defence, but the king and Somerset sent them no aid, and Bordeaux was finally compelled to surrender. The loss of Guienne added the last straw to the burden of Somerset's misdeeds. York, aided by several other peers, took up arms to compel the king to send away his shiftless minister. Henry called out an army, and faced York in Kent; but both were unwilling to strike the first blow, and on receiving a promise that Somerset should be dismissed, and tried before his peers, the duke sent his men home.
