On the very morning in which this report reached Paris, a deposition was presented to Napoleon, made by the servant of George Cadoudal, in which he stated that a prince was at the head of the conspiracy, that he believed this Prince to be in France, as he had often seen at the house of Cadoudal a well dressed man, of distinguished manners, whom all seemed to treat with profound respect. This man, thought Napoleon, must certainly be the Duke d'Enghien, and his interviews with the conspirators will account for his frequent absence from Ettenheim. Another very singular circumstance greatly strengthened this conclusion. There was a Marquis de _Thumery_ in the suite of the Duke d'Enghien. The German officer, who repeated this fact, mispronounced the word so that it sounded like Dumuner, a distinguished advocate of the Bourbons. The officer sent by Napoleon to make inquiries, consequently reported that General Dumuner was with the Duke d'Enghien. All was now plain to the excited mind of the First Consul. The Duke d'Enghien was in the conspiracy. With General Dumuner and an army of emigrants he was to march into France, by Strasburg, as soon as the death of the First Consul was secured; while the Count d'Artois. aided by England, would approach from London. A council was immediately called, to decide what should be done. The ministers were divided in opinion. Some urged sending a secret force to arrest the Duke, with all his papers and accomplices, and bring them to Paris. Cambacères, apprehensive of the effect that such a violation of the German territory might produce in Europe, opposed the measure. Napoleon replied to him kindly, but firmly, "I know your motive for speaking thus--your devotion to me, I thank you for it. But I will not allow myself to be put to death without resistance. I will make those people tremble, and teach them to keep quiet for the time to come." Orders were immediately given for three hundred dragoons to repair to the banks of the Rhine, cross the river, dash forward to Ettenheim, surround the town, arrest the Prince and all his retinue, and carry them to Strasburg. As soon as the arrest was made, Colonel Caulaincourt was directed to hasten to the Grand-duke of Baden, with an apology from the First Consul for violating his territory, stating that the gathering of the hostile emigrants so near the frontiers of France, authorized the French government to protect itself, and that the necessity for prompt and immediate action rendered it impossible to adopt more tardy measures. The duke of Baden expressed his satisfaction with the apology.
