In February 1537 there was a new rising  in Cumberland and Westmorland, called Bigod's Rebellion, under Sir Francis Bigod, of Settrington in the North Riding of Yorkshire. Because he knew the promises he made on behalf of the King would not be met, Norfolk reacted quickly to the new uprising after the Pilgrims did not disperse as they had promised. The rebellion failed and King Henry arrested Bigod, Aske and several other rebels, such as Darcy, John Hussey, 1st Baron Hussey of Sleaford, the Chief Butler of England; Sir Thomas Percy and Sir Robert Constable. All were convicted of treason and executed. During 1537 Bigod was hanged at Tyburn; Lords Darcy and Hussey both beheaded; Thomas Moigne, M.P. for Lincoln was hanged, drawn and quartered; Sir Robert Constable hanged in chains at Hull; and Robert Aske hanged in chains at York. In total 216 were executed: several lords and knights , 6 abbots , 38 monks, and 16 parish priests. Sir Nicholas Tempest, Bowbearer of the Forest of Bowland, was hanged at Tyburn, Sir John Bulmer hanged, drawn and quartered and his wife Margaret Stafford burnt at the stake. In late 1538, Sir Edward Neville, Keeper of the Sewer, was beheaded. The loss of the leaders enabled the Duke of Norfolk to quell the rising, and martial law was imposed upon the demonstrating regions. Norfolk executed some 216 activists : churchmen, monks, commoners. The details of the trial and execution of major leaders were recorded by the author of Wriothesley's Chronicle::63-4
