 With the support of the southwestern French nobility, the English would be able to focus their energies more in defending northern France, strengthening their hold on the entirety of their French territories.The capitulation created a challenge to Charles VII.The King of France, whose disputed legitimacy to such title was the cause of the whole war itself, was expected to protect his vassals in times of adversity, and failure to do so would justify Albret and other vassals recognizing as king another (in this case the King of England) who could do a better job of offering protection.
