Napoleon's letters to Josephine during the Austerlitz campaign have been preserved; unfortunately, we have not hers to him. The Emperor writes very differently from General Bonaparte. His letters are not the ardent, passionate, romantic epistles recalling the fervid style and thought of the _Nouvelle Heloise_. They are substantial letters, concise and interesting, such as a good husband might write after ten years of marriage, but not at all a lover's letters. Josephine, who was quite observant, must have noticed the difference, but she had enough tact and prudence to avoid complaint. 1805 was not 1796; Napoleon still loved Josephine, but from habit, gratitude, and a sense of duty, not with mad passion. He paid her much attention, held her in high regard, felt sympathy with her, deference, and friendship, but scarcely love. Beneath the vaulted roof of Notre Dame Napoleon had given to Josephine the Imperial diadem, but he had not given her the true crown,--love. October 1 the Emperor took command of his army, which had assembled with wonderful promptness on the Rhine. The next day he wrote to the Empress from Marenheims: "I am still very well, and leaving for Strassburg, where I shall arrive this evening. The advance has begun. The armies of Wuertemberg and of Baden are joining mine. I have a good position and love you." October 4 he wrote to her: "I am at Ludwigsberg, and leave to-night. There is no news. All the Bavarians have joined me. I am well. I hope in a few days to have something interesting to tell you. Keep well and believe that I love you. There is a very fine court here, a pretty bride, and the people are pleasant, even the Elector's wife, who seems very good, although she is a daughter of the King of England." October 5 Napoleon sent another letter to Josephine from Ludwigsberg: "I have at once to continue my march. You will be five or six days without news of me; don't be anxious; it is on account of the operations we undertake. Are you as well as I could hope? Yesterday I was at the wedding of the son of the Elector of Wuertemberg with a niece of the King of Prussia. I want to give her a present of from thirty-six to forty thousand francs. Have it made and send it by one of my chamberlains to the bride when the chamberlains are coming to me. Do this at once. Good by; I love and kiss you."
