<h3>how did the english manage to retain calais after the fall of the rest of english held france?</h3>

Calais remained in English hands until it was lost by Mary and Phillip around a century later, how on earth did they defend Calais at the time of Joan of arc's reconquest and for the remaining time it was held? Presumably by agreement? I assume the same applies to Gibraltar but I understand that more due to British naval ability does the same apply here?

PS it's back in English hands now though frenchies!!
