[1] In January 1465, Woodville's sister, Elizabeth, queen consort of King Edward IV of England, procured his marriage to Katherine Neville, Dowager Duchess of Norfolk, who was aunt to the powerful Richard Neville, Earl of Warwick.
In a parley, the rebels told the king that they had no fight with him, but advised him to distance himself from the Woodvilles.
They were captured by Warwick's men on the western bank of the Severn and taken to Coventry in Warwickshire.
Before leaving Calais to support the uprising, Warwick had published a manifesto citing the Woodvilles in general and the earl and John Woodville specifically as his reason for supporting Clarence against the king.
The publication of this manifesto was deemed by Warwick to justify the execution of Rivers and his son.
