Napoleon had a far better idea of the difficulties, but he did not consider the expedition as hopeless. But even if it failed, he would be the winner, because England would be compelled to send most of her navy to India, while Russia would be too fully occupied, to interfere with his projects in Europe. The Cossacks started on their long journey, by crossing the Volga on the floating ice when, on the 24th of March, 1801, Paul was assassinated in his palace. There was no doubt as to the guilty men, but Paul's son, Alexander, who succeeded him, did not order an investigation. Pahlen, Panine, (p. 198) Zoubof, and others, known as the "men of the 24th of March," were removed from office, but that was their only punishment. Paul's mother had alienated her grandchildren from the father, and Alexander always showed greater affection for Catherine than for Paul. The greatest sufferer was Napoleon, who saw his grand schemes go up in smoke. Alexander reversed his father's policy, both at home and abroad. He came to an understanding with England. Napoleon tried earnestly to secure the new czar's friendship. He wanted a free hand in Europe and in return offered the same privilege in Asia, but Alexander mistrusted the First Consul. The murder of the Duke of Enghien, who, by Napoleon's order, was kidnaped in a neutral territory and shot,--still further alienated the czar. After Napoleon's coronation as emperor, Alexander entered into an alliance with England, whereby he would receive six million dollars for every 100,000 men Russia placed in the field. The Emperor of Austria and the King of Prussia joined, but the Austrians, whose generals seemed unable to learn by experience, were defeated before the Russian army could reach the Tyrol. Once again the Russians covered themselves with glory by Koutouzof's masterly retreat to the north, and Bagration's heroic self-sacrifice. At Olmutz, in the presence of Alexander, the Russo-Austrian army, 80,000 strong, was attacked by Napoleon with 70,000 men. The Austrians had induced the czar to adopt their plan of battle, and it met with the usual result. Alexander escaped, escorted by his physician, two Cossacks, and a company of the Guards. (Dec. 2., 1805.) Twenty-four days later Alexander concluded peace with France by the Treaty of Presburg. (p. 199) The growing power of Napoleon induced Alexander to enter into a new coalition with England, Prussia, and Sweden. Russia bore the brunt of the war, after Prussia had been rendered harmless after the battles of Jena and Auerstadt. The Russians withdrew from Prussian Poland; they suddenly left their winter quarters and attacked the French. On the 8th of February, one of the bloodiest battles was fought at Eylau; the French claimed the victory, but it was barren of results.
