The Duke of Burgundy "practised secretly," says Commines, "that King Edward might escape," and threatened to break off all trade with Flanders if he were not freed.

Warwick could look for support only to the Lancastrians, but the Lancastrians demanded Henry's restoration as the price of their aid.

Such a demand was fatal to the plan for placing Clarence on the throne, and Warwick was thrown back on a formal reconciliation with the king.

Edward was freed, and Duke and Earl withdrew to their estates for the winter.

But the impulse which Warwick had given to his adherents brought about a new rising in the spring of 1470.
