Meanwhile the Archdukes Charles and John, the latter in command of the army from Italy, were marching hastily towards the opposite side of the Danube. Napoleon, seeking to strike a blow before a junction between the armies could be made, crossed the river by the aid of bridges thrown from the island of Lobau and occupied the villages of Aspern and Essling.

This was done on May 20th, but during that night the strong current of the river carried away the bridge, leaving the French in a perilous situation. On the afternoon of the 21st the entire Austrian army, 70,000 to 80,000 strong, attacked the French in the two villages, who held their posts only with the greatest difficulty.

By dawn of the 21st more than 70,000 French had crossed, but at this critical interval the bridge again gave way, broken by the fireships and the stone-laden boats sent by the Austrians down the swift current. The struggle went on all day, the bridge being again built and again broken, and at night the French, cut off from their supply of ammunition, were forced to retreat. Napoleon, for the first time in his career, had met with defeat. More than 40,000 dead and wounded lay on that fatal field, among them the brilliant Marshal Lannes, one of Napoleon’s ablest aids.

VICTORY AT WAGRAM

Napoleon, however, had no thought of yielding his hold upon Vienna. He brought forward new troops with all haste, until by July 1st he had an army of 150,000 men. The Austrian army had also been augmented and now numbered 135,000 or 140,000 men. They had fortified the positions of the recent battle, expecting a new attack in that quarter.

But of this Napoleon had no intention. He had selected the heights from Neusiedl to Wagram, occupied by the Austrians, but not fortified by them, as a more favorable point, and during the night of July 4th he threw fresh bridges from Lobau to the main land and set in motion the strong force occupying the island. This moved against the heights of Wagram, occupying Aspern and Essling in its advance.

The battle of the next day was one of desperate fury. Finally the height was gained, giving the French the key of the battlefield. The Archduke Charles looked in vain for the army under his brother John, which failed to appear, and, assailed at every point, was obliged to order a retreat. But this was no rout. The retreat was conducted slowly and in battle array. Both the Russians and the Austrians were proving worthy antagonists of the great Corsican. Further hostilities were checked by a truce, preliminary to a treaty of peace, signed October 14, 1809.

Ambition, unrestrained by caution, uncontrolled by moderation, has its inevitable end. An empire built upon victory, trusting solely to military genius, prepared for itself the elements of its overthrow. This fact Napoleon was to learn. In the outset of his career he opposed a new art of war to the obsolete one of his enemies, and his path to empire was over the corpses of slaughtered armies and the ruins of fallen kingdoms. But year by year his foes learned his art, in war after war their resistance grew more stringent, each successive victory was won with more difficulty and at greater cost, and finally, at the crossing of the Danube, the energy and genius of Napoleon met their equal, and the standards of France, for the first time under Napoleon’s leadership, went back in defeat. It was the tocsin of fate. His career of victory had culminated. From that day its decline began.

THE CAMPAIGN IN SPAIN

The second check to Napoleon’s triumphant career came from one of the weaker nations of Europe, aided by the British under a commander of renown. Napoleon, as already stated, after overturning Spain had been called away by the Austrian war. This ended by the treaty of peace, he filled Spain once more with his veterans, increasing the strength of the army there to 300,000 men, under his ablest generals, Soult, Massena, Ney, Marmont, Macdonald and others. They marched through Spain from end to end, yet, though they held all the salient points, the people refused to submit, but from their mountain fastnesses kept up a petty and annoying war.
