The infantry of the Royal Guard consisted of four battalions. A Grenadier Guard Battalion (Grenadier-Garde-Bataillion) and three battalions which formed the Regiment of Guards. All members of the guards battalions were referred to as grenadiers while men in the grenadier companies were designated "Flügel-Grenadieres". After the defeats of Jena–Auerstedt the Guards, along with the rest of the army were reorganised. Only one small detachment survived initially and it formed a nucleus of two new companies that were formed in January 1807. These were gradually built up and by 1809 it comprised three battalions. Two battalions formed "Garde-Regiment zu Fuß" augmented by "Garde-Füsilier-Bataillon". In 1813 a second Guard regiment was formed from existing infantry and a sharpshooter battalion, "Garde-Schützen-Bataillon" of men from Neuchâtel
