The Duke's Opposition, 1450–1453
In 1450, the defeats and failures of the English royal government of the previous ten years boiled over into serious political unrest. In January Adam Moleyns, Lord Privy Seal and Bishop of Chichester, was lynched. In May the chief councillor of the king, William de la Pole, 1st Duke of Suffolk, was murdered on his way into exile. The House of Commons demanded that the king take back many of the grants of land and money he had made to his favourites.
In June 1450, Kent and Sussex rose in revolt. Led by Jack Cade (taking the name Mortimer), they took control of London and killed James Fiennes, 1st Baron Saye and Sele, the Lord High Treasurer of England. In August, the final towns held in Normandy fell to the French and refugees flooded back to England.
On 7 September 1450, York landed at Beaumaris, Anglesey. Evading an attempt by Henry to intercept him, and gathering followers as he went, York arrived in London on 27 September. After an inconclusive (and possibly violent) meeting with the king, York continued to recruit, both in East Anglia and the west. The violence in London was such that Somerset, back in England after the collapse of English Normandy, was put in the Tower of London for his own safety.
York's public stance was that of a reformer, demanding better government and the prosecution of the "traitors" who had lost northern France. Judging by his later actions, there may also have been a more hidden motive—the destruction of Somerset, who was soon released from the Tower. York's men made several attacks on the properties and servants of the Duke of Somerset, who was to be the focus of attack in parliament.
York and his ally, the Duke of Norfolk, returned to London in November with large and threatening retinues. The London mob was mobilised to put pressure on parliament itself. However, although granted another office, that of Justice of the Forest south of the Trent, York still lacked any real support outside Parliament and his own retainers. In December Parliament elected York's chamberlain, Sir William Oldhall, as speaker.
In April 1451, Somerset was released from the Tower and appointed Captain of Calais. One of York's councillors, Thomas Young, the MP for Bristol, was sent to the Tower when he proposed that York be recognised as heir to the throne, and Parliament was dissolved. Henry VI was prompted into belated reforms, which went some way to restore public order and improve the royal finances. Frustrated by his lack of political power, York retired to Ludlow.
In 1452, York made another bid for power, but not to become king himself. Protesting his loyalty, he aimed to be recognised as Henry VI's heir to the throne (Henry was childless after seven years of marriage), while also continuing to try to destroy the Duke of Somerset. Henry may have preferred Somerset to succeed him over York, as Somerset was a Beaufort descendant.
Gathering men on the march from Ludlow, York headed for London, only to find the city gates barred against him on Henry's orders. At Dartford in Kent, with his army outnumbered, and the support of only two of the nobility (the Earl of Devon and Lord Cobham), York was forced to come to an agreement with Henry. He was allowed to present his complaints against Somerset to the king, but was then taken to London and after two weeks of virtual house arrest, was forced to swear an oath of allegiance at St Paul's Cathedral.
