At Potsdam the Emperor visited the celebrated palace of Sans Souci and found the room of Frederick the Great as it had been in his lifetime, and guarded by one of his old servants. He then went to the Protestant church which contained the hero's tomb. "The door of the monument was open," says General de Segur. "Napoleon paused at the entrance, in a grave and respectful attitude. He gazed into the shadow enclosing the hero's ashes, and stood thus for nearly ten minutes, motionless, silent, as if buried in deep thought. There were five or six of us with him: Duroc, Caulaincourt, an aide-de-camp, and I. We gazed at this solemn and extraordinary scene, imagining the two great men face to face, identifying ourselves with the thoughts we ascribed to our Emperor before that other genius whose glory survived the overthrow of his work, who was as great in extreme adversity as in success." The eighteenth bulletin said of this tomb: "The great man's remains are enclosed in a wooden coffin covered with copper, and are placed in a vault, with no ornaments, trophies, or other distinction recalling his great actions." The Emperor presented to the Invalides in Paris Frederick's sword, his ribbon of the Black Eagle, his general's sash, as well as the flags carried by his guard in the Seven Years' War. The old veterans of the army of Hanover received with religious respect everything which had belonged to one of the first captains whose memory is recorded in history. When he saw that the Prussian court had not thought of making those relics safe from invasion, the hero of Jena, who on this occasion abused his victory, exclaimed as he pointed to the famous sword: "I prefer that to twenty millions." In his letters to Josephine, Napoleon made no mention of his impressions in the house of Frederick. He simply wrote, October 24: "I have been at Potsdam since yesterday, and shall spend to-day here. I continue to be satisfied with everything. My health is good; the weather is fine. I find Sans Souci very agreeable. Good by, my dear. Much love to Hortense and M. Napoleon."
