Evidently the military authorities had never anticipated the possibility that the mob would rise to such a height of audacity.

But the rioters were now encouraged by two days of unbroken success, and those who spurred them on were well-informed as well as fearless.

They knew that the castle was in such a state that its apparent strength was its real weakness; that its entire garrison consisted of little more than a hundred soldiers, most of whom were superannuated veterans, a force inadequate to man one-tenth of the defenses; and that the governor, De Launay, though personally brave, was a man devoid of presence of mind, and nervous under responsibility.
Led by a brewer, named Santerre, who for the next three years bore a conspicuous part in all the worst deeds of ferocity and horror, they assailed the gates in vast numbers.

While the attention of the scanty garrison was fully occupied by this assault, another party scaled the walls at a point where there was not even a sentinel to give the alarm, and let down one draw-bridge across the fosse, while another was loosened, as is believed, by traitors in the garrison itself.

Swarming across the passage thus opened to them, thousands of the assailants rushed in; murdered the governor, officers, and almost every one of the garrison; and with a savage ferocity, as yet unexampled, though but a faint omen of their future crimes, they cut off the head and hands of De Launay and several of their chief victims, and, sticking them on pikes, bore them as trophies of their victory through the streets of the city.
The news of what had been done came swiftly to Versailles, where it excited feelings in the Assembly which, had the king or his advisers been capable of availing themselves of it with skill and firmness, might have led to a salutary change in the policy of that body; for the greater part of the deputies were thoroughly alarmed at the violence of Santerre and his companions, and would in all probability have supported the king in taking strong measures for the restoration of order.
