Title:
Napoleon

Context:
Some contemporaries alleged that Bonaparte was put under house arrest at Nice for his association with the Robespierres following their fall in the Thermidorian Reaction in July 1794, but Napoleon's secretary Bourrienne disputed the allegation in his memoirs. According to Bourrienne, jealousy was responsible, between the Army of the Alps and the Army of Italy (with whom Napoleon was seconded at the time). Bonaparte dispatched an impassioned defense in a letter to the commissar Salicetti, and he was subsequently acquitted of any wrongdoing.

Question:
When did the Thermidorian Reaction take place?

July 1794
