He began to cross the river Niemen, which empties into the Baltic, on the night of June 23, 1812. The policy of the Russians was to retreat, burning the towns through which they passed, and destroying all produce, that the French might find no support in the desolated country.

The first terrible battle was at Borodino, Sept. 7, where the French lost about thirty thousand, and the Russians fifty thousand, in killed and wounded.

On Sept. 14, Napoleon and his weary army—many thousands had been stationed at various places along the route—entered Moscow. Here they hoped for food and rest. They found the great city deserted. Powder had been placed under the Kremlin, and shells under the larger palaces, where Napoleon and his officers would be apt to lodge; water-pipes had been cut, fountains destroyed; and, the day after Napoleon's arrival, the whole city was set on fire by Russians detailed for that purpose. No wonder Napoleon said, years later, of this terrible destruction of a great city, "It was the most grand, the most sublime, the most terrific sight the world ever beheld!"

Napoleon wrote to the Tsar proposing peace; but no answer was ever returned, though he waited some weeks in Moscow, hoping to hear favorably. The more intelligent serfs offered to rise against their masters, and aid Napoleon, but he did not desire civil war.

On Oct. 19, 1812, the Grand Army of France, one hundred thousand strong, commenced its heart-breaking retreat. Deep snow had already come, earlier than usual. Kutusof, the Russian general, moved his army parallel to the French, and fought them at every available point. Marshal Ney covered the rear, and made for himself an immortal record. Napoleon rightly called him "The Bravest of the Brave." When they reached Borodino they sadly turned their heads away from the battle-fields where the bodies of thirty thousand men were half devoured by wolves. The cold became intense. Horses slipped and fell on the icy ground. Artillery and baggage were abandoned. There was no food in the devastated country. Where Napoleon had left provisions on his way to Moscow the enemy had destroyed them. Men ate their horses for food. They lay down at night on the snow to sleep, and never rose. "Every morning," says Marbot, "we left thousands of dead in our bivouacs.... So intense was the cold that we could see a kind of vapor rising from men's ears and eyes. Condensing, on contact with the air, this vapor fell back on our persons with a rattle such as grains of millet might have made. We had often to halt and clear away from the horses' bits the icicles formed by their frozen breath.... Many soldiers of all ranks blew out their brains to put an end to their misery.... All ranks were confounded; there were no arms, no military bearings; soldiers, officers, generals, were clad in rags, and for boots had nothing but strips of leather or cloth, hardly fastened together with a string." The Emperor himself was grave, calm, and self-controlled, with no diminution of courage.

The soldiers of the allies of Napoleon, Austria, Prussia, Spain, and others, deserted by the thousands, the Russians having sent proclamations in various languages into the camps, telling them they should be returned to their homes.

Finally they reached the river Beresina, the bridge over which had been destroyed by the Russians. Tearing down the hovels in the village, the French built two bridges at night, the men standing for six or seven hours in the water. Then the troops surged upon them, and one bridge broke under the weight of guns and men. In rushing upon the other, great crowds were forced into the river and drowned. The Russians meantime swept them with cannon. From twenty to twenty-five thousand men perished in this dreadful crossing of the Beresina.

On Dec. 5, 1812, they were within the borders of Poland; and Napoleon, having learned that his death had been proclaimed in Paris, and that a man had tried to usurp the power, left his army in charge of Murat, and, with two officers, hastened by sledges to Paris, which he reached Dec. 18.

The loss of the French army and its allies in the Russian campaign Thiers estimates as 300,000 men; other authorities make it 350,000; 100,000 were killed in the advance and retreat from Moscow; 150,000 died of hunger, fatigue, and cold; 100,000 were taken prisoners. The Russian losses were also heavy.

Prussia now joined herself to Russia, and declared war against France. Napoleon at once raised another army of nearly two hundred thousand by conscription, and defeated the enemy at Lützen, or Gross-Beeren, and Bautzen. His young conscripts fought heroically. His beloved Marshal Duroc was killed just after the latter battle. Napoleon wept as he left him dying, saying, "Duroc, there is another life.... We shall one day meet again."
