2. Lambert Simnel passed off as the Earl of Warwick, who had been imprisoned by Henry

4. Conspiracy put together by John de la Pole, the Earl of Lincoln
5. Henry exhibited the real Earl of Warwick in London
6. Lincoln fled Henry's court and joined the failed plotter Lord Lovell at the court of Margaret of Burgundy in the Netherlands
7. They persuaded Margaret to support Simnel's claim and to pay for a force of mercenaries to invade England
8. Henry took the gamble of reinstating the untrustworthy Earl of Northumberland who led a major portion of Richard III's army at the Battle of Bosworth to power in the North
9. Reinforced coastal defences in East Anglia
10. Rebels landed on the northwest coast of England in Cumberland and crossed the Pennines to drum up support in Richard III's heartland the North Riding of Yorkshire
11. Battle of Stoke Field 1487 - Henry's army led effectively by the Earl of Oxford held firm and the Earl of Lincoln was killed in the battle having crucially been unable to add sufficient followers to the army of mercenaries with which he had landed in England
