The company of cavalry, belonging to the Dauphin's regiment, had behaved badly, and even with cowardice, since the death of their commander Teligny.

The citizens were naturally weary and impatient of the siege.
Mining and countermining continued till the 21st August.

A steady cannonade was then maintained until the 27th.

Upon that day, eleven breaches having been made in the walls, a simultaneous assault was ordered at four of them.

The citizens were stationed upon the walls, the soldiers in the breaches.
