Conspiration Des Poignards

The Conspiration des poignards (Daggers Conspiracy) or Complot de l'Opéra (Opera Plot) was an alleged assassination attempt against Napoleon Bonaparte, the members of the plot were not clearly established. Authorities at the time presented it as an assassination attempt on Napoleon at the exit of the Paris operahouse on 18 vendémiaire year IX (10 October 1800), which was prevented by the police force of Joseph Fouché. However, this version was questioned very early on.

In his Mémoires, Fouché affirmed that, towards mid-September 1800, a plot arose aiming at assassinating Napoleon at the operahouse. Someone named Harel, presented as one of the accomplices, worked in liaison with the war commissioner Lefebvre, to bring the revelations to Louis Antoine Fauvelet de Bourrienne, Napoleon's secretary, indicating the plotters were Roman Cerrachi and Diana, Joseph Antoine Aréna, brother of the Corsican deputy who had declared against the Napoleon; the painter and patriotic fanatic François Topino-Lebrun, and Dominique Demerville, former clerk of the Committee of public safety, closely associated with Bertrand Barère de Vieuzac. Harel was charged with drawing up a trap for the plotters, four armed men, laid out for the assassination of Napoleon, on the evening of October 10, with the performance at opera of Horaces. The day of the attack, the men stationed by the police force, and on the account of which entreated had been misused, instead of stabbing Bonaparte, stopped Diana, Cerrachi and their two complices. all the others presumably retreated and were apprehended at their residence.

For modern historians this was a manipulation by the police force, made possible by an agent provocateur, Harel, who had infiltrated the group. After Plot of the Rue Saint-Nicaise, the members of the "daggers conspiracy", presented as a Jacobin plot, were judged in front of the criminal court of The Seine. Four of them were condemned to death 19 nivôse year IX (January 9, 1801), at eleven o'clock in the evening, after three days of debates and carried out January 30 after rejection of the appeal.
