Either a chamberlain or one of the Emperor's aides-de-camp served as Master of the Wardrobe. He had charge of the clothes, the linen, the lace, the boots and shoes, and of the ribbons of the Legion of Honor. If he assisted at the Emperor's toilet, he had to hand him his coat, fasten his ribbon or collar, give him his sword, hat, and gloves, in the Grand Chamberlain's absence. The Grand Master of Ceremonies determined questions of rank and precedence, drew up and enforced the rules for public, formal ceremonies, for the reception of sovereigns and hereditary princes, and, foreign ambassadors and ministers. The colonels-general of the Imperial Guard and the Emperor's aides also made part of the household. At ceremonies when the Emperor was in his state-coach, there were two colonels-general of the Guard at the left door. When he rode, all four followed close behind. The Grand Equerry, or his substitute, had a place among them. The colonel-general on duty received directly the Emperor's orders relative to the different requirements of the Imperial Guard, and transmitted them directly to the other colonels-general. He was quartered in the palace, in preference to any other officer of the Crown, and as near as possible to the Emperor's apartment, whether at the residence or when travelling. In the field he slept in the Emperor's tent. Napoleon had twelve aides-de-camp. The one on duty was called the aide-de- camp of the day, He always had a horse saddled or a carriage harnessed ready in the stable, to carry any messages the Emperor might give. As soon as the Emperor had gone to bed, the aide-de-camp on duty was especially entrusted with guarding him, and he slept in an adjoining room. In the field the Emperor's aides served as chamberlains.
