Neither Artois nor his son Berry had entered France; the self-styled Louis XVIII was in distant Warsaw. Both these pretenders were more eloquent than courageous. Even the royalists of Paris were doubtful about the leadership of either one, and the partizans of constitutional monarchy had for some time been disposed to rally about a third Bourbon, the Duc d'Enghien, heir apparent to the glories of the house rendered so illustrious by Louis XIV's famous general known as "the Great Condé." The young duke was both fearless and clever. Burning to take arms in honorable warfare for the cause of his house, he had consulted both English and emigrant agents as to how that could best be accomplished; but he was innocent of conspiring for assassination. For some time he had lived in close proximity to the French frontier at Ettenheim, a manor-house in Baden, some sixteen miles from Strasburg, where Cardinal Rohan had resided with his niece since his resignation of the bishopric of Strasburg after the Concordat. The duke had for some time been secretly married to this lady, the Princess Charlotte of Rohan-Rochefort, and for that reason, though repeatedly warned of his danger, would not take refuge in England. Before the treaty of Amiens he had been the friend of the Swiss reactionaries and the patron of the royalists in Alsace; after the rupture he was active in strengthening their attachment to the Bourbon cause. In response to the manifesto of the self-styled king, his relative at Warsaw, issued in March, 1803, he declared that he was still faithful. When war began he sought permission to enter the English service and repel the expected invasion by Bonaparte; but England would not permit a Bourbon to draw sword on her soil. At this crisis the publication of the Warsaw manifesto, and of the duke's response, made his continued residence at Ettenheim a subject of still greater inquietude to his friends; but he remained, and spent much energy in forming plans to invade France through Alsace. As the probabilities of war on the Continent grew stronger, he again applied to the English court for a commission, this time through Stuart, the British envoy to Vienna. He now desired employment on the mainland, either in an allied army or with the first English troops which should disembark on the Continent. Meantime the activity of the English residents at the minor German courts intensified his purpose to raise a regiment of men from the anti-Bonaparte elements of central Europe, to be officered by the scattered veterans who had fought under the second Condé but had been dismissed from the Austrian service after the treaty of Lunéville. The news of Moreau's arrest and of Cadoudal's conspiracy came like a thunderbolt, and the duke, though conscious of no guilt, made ready to withdraw to Freiburg in the Breisgau; but in order to mask his uneasiness he instituted a hunt and other festivities which lasted a whole week.
