The situation remained in stalemate for some time, with Charles of Blois as de facto duke, but with significant territory still controlled by the Montfortists.
The war resumed in 1363 when Charles de Blois, assisted by Bertrand du Guesclin, had some successes, but when Bertrand left to take control of strongholds in Navarre and Normandy, Charles's advance halted at the unsuccessful siege of Bécherel.
