Jean-Nicolas Pache participant of French Revolution
Impact
Jean Nicholas Pache may not have single-handedly brought down the Girondin, but his determination played an important role.  Pache was a key player in changing the political scene in Paris in this time.  
Pache  also helped to truly give power to the people of Paris.  The people of Paris had successfully humiliated the Convention in forcing it to do their bidding and the convention would not recover this lost power until the Thermidorian Reaction shattered the power of the Jacobin Clubs and sans culottes.  The people of Paris would not forget this and the legacy of "the people in arms" would have a long-term impact on the French revolutionary tradition, in the readiness of the Parisian population to "rush to the barricades," through the 19th and 20th centuries.
