Rupture of the Peace of Amiens.

The peace of Amiens was of short duration. In May, 1803—but fourteen months after the signing of the treaty—England again renewed hostilities without even a declaration of war. This was the signal for new scenes of blood and woe. Napoleon now resolved to assail his implacable foe by carrying his armies into the heart of England. Enormous preparations were made upon the French coast to transport a resistless force across the Channel. Joseph Bonaparte was placed in command of a regiment of the line, which had recently returned, with great renown, from the fields of Italy.

In the midst of these preparations, which excited fearful apprehensions in England, the British Government succeeded in organizing another coalition with Austria and Russia, to fall upon France in the rear. The armies of these gigantic Northern powers commenced their march toward the Rhine. Napoleon broke up the camp of Boulogne and advanced to meet them. The immortal campaigns of Ulm and Austerlitz were the result. Incredible as it may seem, England represented this as an unprovoked invasion of Germany by Napoleon. This incessant assault of the Allies upon France was a great grief to the Emperor. In the midst of all the distractions which preceded this triumphant march, he wrote to his Minister of Finance:

"I am distressed beyond measure at the necessities of my situation, which, by compelling me to live in camps, and engage in distant expeditions, withdraw my attention from what would otherwise be the chief object of my anxiety, and the first wish of my heart—a good and solid organization of all which concerns the interests of banks, manufactures, and commerce."

While Napoleon was absent upon this campaign, Joseph was left in Paris, to attend to the administration of home affairs. This he did, much to the satisfaction of Napoleon, and with great honor to himself. Napoleon was now Emperor of France, and the Senate and the people had declared Joseph and his children heirs of the throne, on failure of Napoleon's issue.

Conspiracy to assassinate Napoleon.

A gigantic conspiracy was formed in England by Count d'Artois, subsequently Charles X., and other French emigrants, for the assassination of Napoleon. The plan was for a hundred resolute men, led by the desperate George Cadoudal, to waylay Napoleon when passing, as was his wont, with merely a small guard of ten outriders, from the Tuileries to Malmaison. The conspirators flattered themselves that this would be considered war, not assassination. The Bourbons were then to raise their banner in France, and the emigrants, lingering upon the frontiers, were to rush into the empire with the Allied armies, and re-establish the throne of the old régime. The Princes of Condé grandfather, son, and grandson, were then in the service and pay of Great Britain, fighting against their native land, and, by the laws of France traitors, exposed to the penalty of death. The grandson, the Duke d'Enghien, was on the French frontier, in the duchy of Baden, waiting for the signal to enter France arms in hand.

It was supposed that he was actively engaged in the conspiracy for the assassination, as he was known frequently to enter France by night and in disguise. But it afterward appeared that these journeys were to visit a young lady to whom the duke was much attached.
