Napoleon had no such intention. He had selected the heights ranging from Neusiedl to Wagram, strongly occupied by the Austrians, but not fortified, as his point of attack, and on the night of July 4th bridges were thrown from the island of Lobau to the mainland, and the army which had been gathering for several days on the island began its advance. It moved as a whole against the heights of Wagram, occupying Aspern and Essling in its advance. [=The Victory at Wagram=] The great battle began on the succeeding day. It was hotly contested at all points, but attention may be confined to the movement against the plateau of Wagram, which had been entrusted to Marshal Davout. The height was gained after a desperate struggle; the key of the battlefield was held by the French; the Austrians, impetuously assailed at every point, and driven from every point of vantage, began a retreat. The Archduke Charles had anxiously looked for the coming of his brother John, with the army under his command. He waited in vain, the laggard prince failed to appear, and retreat became inevitable. The battle had already lasted ten hours, and the French held all the strong points of the field; but the Austrians withdrew slowly and in battle array, presenting a front that discouraged any effort to pursue. There was nothing resembling a rout. The Archduke Charles retreated to Bohemia. His forces were dispersed during the march, but he had 70,000 men with him when Napoleon reached his front at Znaim, on the road to Prague, on the 11th of July. Further hostilities were checked by a request for a truce, preliminary to a peace. The battle, already begun, was stopped, and during the night an armistice was signed. The vigor of the Austrian resistance and the doubtful attitude of the other powers made Napoleon willing enough to treat for terms. [=The Peace of Vienna=] The peace, which was finally signed at Vienna, October 14, 1809, took from Austria 50,000 square miles of territory and 3,000,000 inhabitants, together with a war contribution of $85,000,000, while her army was restricted to 150,000 men. The overthrow of the several outbreaks which had taken place in north Germany, the defeat of a British expedition against Antwerp, and the suppression of the revolt in the Tyrol, ended all organized opposition to Napoleon, who was once more master of the European situation.
