Napoleon, while following up his success with his customary rapidity and advancing with his main body straight upon Vienna, despatched Ney into the Tyrol, where the peasantry, headed by the Archduke John, made a heroic defence. The advanced guard of the French, composed of the Bavarians under Deroy, were defeated at the Strub pass, but, notwithstanding this disaster, Ney carried the Schaarnitz by storm and reached Innsbruck. The Archduke John was compelled to retire into Carinthia in order to form a junction with his brother Charles, who, after beating Massena at Caldiero, had been necessitated by Mack's defeat to hasten from Italy for the purpose of covering Austria. Two corps, left in the hurry of retreat too far westward, were cut off and taken prisoner, that under Prince Rohan at Castellfranco, after having found its way from Meran into the Venetian territory, and that under Jellachich on the Lake of Constance; Kinsky's and Wartenleben's cavalry threw themselves boldly into Swabia and Franconia, seized the couriers and convoys to the French rear, and escaped unhurt to Bohemia. Davoust had, in the meanwhile, invaded Styria and defeated a corps under Meerveldt at Mariazell. In November, Napoleon had reached Vienna, neither Linz nor any other point having been fortified by the Austrians. The great Russian army under Kutusow appeared at this conjuncture in Moravia. The czar, Alexander I., accompanied it in person, and the emperor, Francis II., joined him with his remaining forces. A bloody engagement took place between Kutusow and the French at Durrenstein on the Danube, but, on the loss of Vienna, the Russians retired to Moravia. The sovereigns of Austria and Russia loudly called upon Prussia to renounce her alliance with France, and, in this decisive moment, to aid in the annihilation of a foe, for whose false friendship she would one day dearly pay. The violation of the Prussian territory by Bernadotte had furnished the Prussian king with a pretext for suddenly declaring against Napoleon. The Prussian army was also in full force. The British and the Hanoverian legion had landed at Bremen and twenty thousand Russians on Rugen; ten thousand Swedes entered Hanover; electoral Hesse was also ready for action. The king of Prussia, nevertheless, merely confined himself to threats, in the hope of selling his neutrality to Napoleon for Hanover, and deceived the coalition.[8] The emperor Alexander visited Berlin in person for the purpose of rousing Prussia to war, but had no sooner returned to Austria in order to rejoin his army than Count Haugwitz, the Prussian minister, was despatched to Napoleon's camp with express instructions not to declare war. The famous battle, in which the three emperors of Christendom were present, took place, meanwhile, at Austerlitz, not far from Brunn, on the 2d of December, 1805, and terminated in one of Napoleon's most glorious victories.[9] This battle decided the policy
