The time for the momentous struggle had arrived. Napoleon, the master of Continental Europe, thought that he was more than a match for serf-ridden Russia. He reckoned upon the echo which the words liberty, equality, and fraternity, would awaken in the hearts of the moujik, and forgot that they were abstract ideas which to the serf, struggling for enough black bread to allay the cravings of hunger, were so many empty sounds. He tried to arouse Europe's suspicions of Russia's designs, not thinking that any yoke, even that of the Tartars, would be a welcome relief to nations mourning for the slaughter of their sons.

Napoleon left Paris for Dresden on the 9th of May, 1812; on the first of June an army of 678,000 men, including 60,000 Poles, stood ready to invade Russia. Alexander had only 150,000 men under Bagration and Barclay de Tolly, 90,000 posted on the Niemen, and 60,000 on the Vistula; but he issued a proclamation announcing a Holy War. "Rise all of you!" he urged, "With the Cross in your hearts and arms in your hands, no human force can prevail against you!"

Napoleon advanced clutching shadows. After his army left Wilna, leaving dead desolation in its wake, the time soon came when retreat was no longer possible. Russian patriotism clamored for battle and Russian prudence had to give way to it. All of Koutouzof's remarkable influence was required to restrain his men under the retreat which foretold victory, because every step forward sealed Napoleon's doom. The Corsican knew it but, with the superstition born in him, trusted to his star. Finally he drew near Moscow, the Holy City, where Count Rostopchine, the governor, was preparing the grand climax of the drama, while pacifying Russian patriotism by a series of hardy falsehoods. "I have resolved," he explained, "at every disagreeable piece of news to raise doubts as to its truth; by this means, I shall weaken the first impression, and before there is time to verify it, others will come which will require investigation." The people implicitly believed his most daring inventions. When he evacuated Moscow, he ordered all prisons to be opened, and the guns in the arsenal to be distributed among the people; he also had the pumps removed and finally gave instructions to set fire to the stores of vodka and the boats loaded with alcohol.

Napoleon arrived at the Kremlin on the 14th of September. Short as was his sojourn, it was with difficulty that he escaped through the flames and found refuge in a park. Why did he waste thirty-five days in the charred capital? Was it belief in his star, or was it despair at the ruin of his prospects? On the 13th of October, the remnant of the Grand Army started on its long journey over the desert it had left behind, because all other roads were closed to it. The retreat has been described by many writers; but what pen shall do justice to the suffering caused by the unusually severe winter, the snow, the ice, the hunger, and the thirst? And how many hearts were rent, when the news came of the dead, the wounded, and the missing? Napoleon's campaign in Russia was the most impressive sermon against war, but it fell upon heedless ears.

After the Battle of the Berezina, Napoleon left the army and hurried home. All his thoughts were on the effect of the disastrous defeat,—not upon the hundred thousand desolate homes, but upon his own fortunes. He arrived in Paris where he gathered 450,000 men, many of them mere youths, to support him with their blood. But Europe was weary of slaughter. Kings might tremble for their crowns, it was the people, aroused to frenzy, that impelled them to action. On Napoleon's heels, besides, there was a bloodhound whom nobler instincts than mere self-preservation inspired to ceaseless pursuit. Alexander I, at this time, earned and deserved the glorious surname of The Well-beloved. Not a thought of self-glory or personal aggrandizement sullied the relentless chase. Emperors and kings dreading the awakened conscience of the people would have made peace, and they could have done so with security for themselves, but Alexander said, "No!" Under fire at the four days' battle of Leipzig, he personally directed reënforcements where they were required. And when, at last, the host of invaders stepped on the soil whose people during twenty years had committed outrages in almost every known country of Europe, they were noble words which the Autocrat addressed to his troops whom he had brought so far away from home. "By invading our empire," he says, "the enemy has done us much harm, and has therefore been subjected to a terrible chastisement. The anger of God has overthrown him. Do not let us imitate him. The merciful God does not love cruel and inhuman men. Let us forget the evil he has wrought; let us carry to our foes, not vengeance and hate, but friendship, and a hand extended in peace."

These were not mere words; Alexander the Well-beloved was sincere. But it was he who refused to receive Napoleon's envoy at Freiburg, and it was he who, when Napoleon, fighting like a tiger at bay, was defeating the separated armies, so that the British envoy urged to come to terms with him, answered, "It would not be a peace but a truce. I cannot come four hundred leagues to your assistance every day. No peace, so long as Napoleon is on the throne!" By his direction the united armies rolled like an avalanche upon Paris,—and Napoleon gave up the struggle by abdicating.

Again it was Alexander the Well-beloved who intervened when other powers would have overwhelmed the fallen colossus. It was Alexander who procured for his enemy the sovereignty of the island of Elba, and commissioned Count Schouvalof to escort him. "I confide to you a great mission;" he said; "you will answer to me with your head for a single hair which falls from the head of Napoleon."

At the Congress of Vienna assembled the statesmen to dispose of nations and peoples, as their own ambition prompted. Alexander desired to unite Poland to his crown, but separate from Russia; but was opposed by Austria, Great Britain, and France, who entered into a secret alliance against him. Had Napoleon waited two hundred days instead of half that time, who knows that he might not yet have been the arbiter of Europe? His descent united all factions, and Alexander declared that he would pursue Napoleon "down to his last man and his last ruble."

Once again armies were set in motion, and once again Napoleon resorted to his well-known tactics of destroying his enemies one by one. He failed at Waterloo. (June 17, 1815.) Again the allies re-entered Paris, the Prussians first but closely followed by the czar and his army.

"Justice, but no revenge!" proclaimed Alexander when Blücher would have followed Napoleon's example of robbing a country of its works of art. The czar stood the friend of France when Prussia demanded a frontier which would render her safe from French invasion; but he said frankly that he "wished to allow some danger to exist on that side, so that Germany, having need of Russia, might remain dependent," He was in favor of allowing the French to select their own government, but was overruled. At last the allies came to an understanding, and Poland was joined to the Russian Crown.
