Napoleon himself underwent a complete change of habits and demeanor. Where he had been rough and coarse he became attentive and refined. His shabby uniforms were all discarded, and he spent hours in trying on new costumes. He even attempted to learn to waltz, but this he gave up in despair. Whereas before he ate hastily and at irregular intervals, he now sat at dinner with unusual patience, and the court took on a character which it had never had. Never before had he sacrificed either his public duty or his private pleasure for any woman. Even in the first ardor of his marriage with Josephine, when he used to pour out his heart to her in letters from Italian battle-fields, he did so only after he had made the disposition of his troops and had planned his movements for the following day. Now, however, he was not merely devoted, but uxorious; and in 1811, after the birth of the little King of Rome, he ceased to be the earlier Napoleon altogether. He had founded a dynasty. He was the head of a reigning house. He forgot the principles of the Revolution, and he ruled, as he thought, like other monarchs, by the grace of God. As for Marie Louise, she played her part extremely well. Somewhat haughty and unapproachable to others, she nevertheless studied Napoleon's every wish. She seemed even to be loving; but one can scarcely doubt that her obedience sprang ultimately from fear and that her devotion was the devotion of a dog which has been beaten into subjection. Her vanity was flattered in many ways, and most of all by her appointment as regent of the empire during Napoleon's absence in the disastrous Russian campaign which began in 1812. It was in June of that year that the French emperor held court at Dresden, where he played, as was said, to "a parterre of kings." This was the climax of his magnificence, for there were gathered all the sovereigns and princes who were his allies and who furnished the levies that swelled his Grand Army to six hundred thousand men. Here Marie Louise, like her husband, felt to the full the intoxication of supreme power. By a sinister coincidence it was here that she first met the other man, then unnoticed and little heeded, who was to cast upon her a fascination which in the end proved irresistible. This man was Adam Albrecht, Count von Neipperg. There is something mysterious about his early years, and something baleful about his silent warfare with Napoleon. As a very young soldier he had been an Austrian officer in 1793. His command served in Belgium; and there, in a skirmish, he was overpowered by the French in superior numbers, but resisted desperately. In the melee a saber slashed him across the right side of his face, and he was made prisoner. The wound deprived him of his right eye, so that for the rest of his life he was compelled to wear a black bandage to conceal the mutilation.
