He laid siege in person to Montereau, an important military post with which a recent and sinister reminiscence was connected.

A great change now made itself apparent in the king's behavior and disposition.

He showed activity and vigilance, and was ready to expose himself without any care for fatigue or danger.

On the day of the assault (10th of October, 1437) he went down into the trenches, remained there in water up to his waist, mounted the scaling- ladder sword in hand, and was one of the first assailants who penetrated over the top of the walls right into the place.

After the surrender of the castle as well as the town of Montereau, he marched on Paris, and made his solemn re-entry there on the 12th of November, 1437, for the first time since in 1418 Tanneguy-Duchatel had carried him away, whilst still a child, wrapped in his bed-clothes.
