Three armies were prepared to act in Normandy, Britanny, and Guienne.

But the first two, with Edward and Henry of Derby, who had been raised to the dukedom of Lancaster, at their head, were detained by contrary winds, and Charles, despairing of their arrival, made peace with John.

Edward made his way to Calais to meet the tidings of this desertion and to be called back to England by news of a recapture of Berwick by the Scots.

But his hopes of Norman co-operation were revived in 1356.

The treachery of John, his seizure of the King of Navarre, and his execution of the Count of Harcourt who was looked upon as the adviser of Charles in his policy of intrigue, stirred a general rising throughout Normandy.
