The country now had two kings — a situation that could not be allowed to persist, especially if Edward were to be formally crowned. Edward offered an amnesty to any Lancastrian supporter who renounced Henry. The move was intended to win over the commoners; his offer did not extend to wealthy Lancastrians (mostly the nobles). The young king summoned and ordered his followers to march towards York to take back his family's city and to depose Henry formally through force of arms. The Yorkist army moved along three routes. Warwick's uncle, Lord Fauconberg, led a group to clear the way to York for the main body, which was led by Edward. The Duke of Norfolk was sent east to raise forces and rejoin Edward before the battle. Warwick's group moved to the west of the main body, through the Midlands, gathering men as they went. On 28 March, the leading elements of the Yorkist army came upon the remains of the crossing in Ferrybridge crossing the River Aire. They were rebuilding the bridge when they were attacked and routed by a band of about 500 Lancastrians, led by Lord Clifford.
