The French Emperor, in executing this decisive movement, was extremely desirous to have possessed himself of Vitry, which lay in the line of his advance. But as this town contained a garrison of about 5000 men, commanded by an officer of resolution, he returned a negative to the summons; and Napoleon, in no condition to attempt a _coup-de-main_ on a place of some strength, passed the Marne on the 22d of March, over a bridge of rafts constructed at Frigincour, and continued his movement towards the eastern frontier, increasing the distance at every step betwixt him and his capital, and at the same time betwixt him and his enemies.
In the meantime, events had taken place in the vicinity of Lyons, tending greatly to limit any advantages which Napoleon might have expected to reap on the south-eastern part of the frontier towards Switzerland, and also to give spirits to the numerous enemies of his government in Provence, where the Royalists always possessed a considerable party.
The reinforcements despatched by the Austrians under General Bianchi, and their reserves, brought forward by the Prince of Hesse-Homberg, had restored their superiority over Augereau's army. He was defeated at Macon on the 11th of March, in a battle which he had given for the purpose of maintaining his line on the Saone. A second time, he was defeated on the 18th at St. George, and obliged to retire in great disorder, with scarce even the means of defending the Isère, up which river he retreated. Lyons, thus uncovered, opened its gates to Bianchi; and, after all that they had heard concerning the losses of the allies, the citizens saw with astonishment and alarm an untouched body of their troops, amounting to 60,000 men, defile through their streets. This defeat of Augereau was probably unknown to Napoleon, when he determined to march to the frontiers, and thought he might reckon on co-operation with the Lyonnese army. Though, therefore, the Emperor's movement to St. Dizier was out of the rules of ordinary war, and though it enabled the allies to conceive and execute the daring scheme which put an end to the campaign, yet it was by no means hopeless in its outset; or, we would rather say, was one of the few alternatives which the crisis of his affairs left to Buonaparte, and which, judging from the previous vacillation and cautious timidity displayed in the councils of the allies, he had no reason to apprehend would have given rise to the consequences that actually followed.
