In October 1536 the men of Lincoln took up arms in defence of their religion. Many of the noblemen were forced to take part in the movement, with which they sympathised, but which they feared to join lest they should be exposed to the merciless vengeance of the king. The leaders proclaimed their loyalty to the crown, and announced their intention of sending agents to London to present their petitions. They demanded the restoration of the monasteries, the removal of heretical bishops such as Cranmer and Latimer, and the dismissal of evil advisers like Cromwell and Rich. Henry VIII. returned a determined refusal to their demands, and dispatched the Earl of Shrewsbury and the Duke of Suffolk to suppress the rebellion. The people were quite prepared to fight, but the noblemen opened negotiations with the king's commanders, and advised the insurgents to disperse. The Duke of Suffolk entered the city of Lincoln amidst every sign of popular displeasure, although since the leaders had grown fainthearted no resistance was offered. Those who had taken a prominent part in the rebellion were arrested and put to death; the oath of supremacy was tendered to every adult; and by the beginning of April 1537, all traces of the rebellion had been removed. The Pilgrimage of Grace in the north was destined to prove a much more dangerous movement. Early in October 1536 the people of York, determined to resist, and by the middle of the month the whole country was up in arms under the leadership of Robert Aske, a country gentleman and a lawyer well-known in legal services in London. Soon the movement spread through most of the counties of the north. York was surrendered to the insurgents without a struggle. Pomfret Castle, where the Archbishop of York and many of the nobles had fled for refuge, was obliged to capitulate, and Lord Darcy, the most loyal supporter of the king in the north, agreed to join the party of Aske. Hull opened its gates to the rebels, and before the end of October a well trained army of close on 40,000 men led by the principal gentlemen of the north lay encamped four miles north of Doncaster, where the Duke of Norfolk at the head of 8,000 of the king's troops awaited the attack. The Duke, fully conscious of the inferiority of his forces and well aware that he could not count on the loyalty of his own soldiers, many of whom favoured the demands of the rebels, determined to gain time by opening negotiations for a peaceful settlement (27th Oct.). Two messengers were dispatched to submit their grievances to the king, and it was agreed that until an answer should be received both parties should observe the truce. The king met the demands for the maintenance of the old faith, the restoration of the liberties of the Church, and the dismissal of ministers like Cromwell by a long explanation and defence of his political and religious policy, and the messengers returned to announce that the Duke of Norfolk was coming for another conference.
