Hi jwhoff.
... thinking about Bastille Day I got to thinking how many of those folks released were later rounded up and beheaded.
None.
As it happened, the Bastille was almost empty of prisoners at the time it was stormed. Although the fighting between the mob and the guards cost over a hundred lives, all the attackers eventually succeeded in freeing were four forgers, two lunatics and one pervert. None of them were political prisoners, all of whom had been moved elsewhere a while before because the Bastille was already in the process of being closed down before it was attacked.
The forgers (Bechade, Lacaurege, Pujade and Laroche) immediately disappeared back into the criminal underworld. The lunatics (Tavernier and de Whyte) were locked up in the asylum at Charenton. The pervert (de Solages) was sent back to his family (even though they didn't want him because his crime was incest). None were executed under the Terror, nor played any role in future events.
In terms of practical results, the storming of the Bastille was a total fiasco. It's celebrated in France as a symbolic revolutionary moment, because it was a government fortress, not because it was actually significant in itself.
T & F,
