Edmund, Earl of Suffolk had escaped abroad in August to raise an army for an invasion of England to support his Yorkist claim to the throne. Until then, Henry VII had allowed him to act as he wished, permitting him for example to succeed to the Suffolk title, but the King now denounced him as a traitor. He was attainted in 1504, and executed by the new king Henry VIII in 1513.
