Grenadier a pied, campaign dress, 1807

On the formation of the Imperial Guard in 1804 the Grenadiers a Pied had a headquarters staff and two battalions of Grenadiers.

Each Grenadier battalion consisted of eight companies. Each company comprised one capitaine, one lieutenant en premier, two lieutenants en seconde, one sergeant-major, three sergeants, one fourrier, eight brigadier-soldats, two sapeurs, two tambours; and 80 grenadiers, making 102 all ranks. The headquarters staff contained one colonel, one major, three chefs de bataillon, three adjutant-majors, three sous adjutant-majors, two porte-drapeaux, three chirurgiens, one tambour-major, three brigadier-tambours, and a regimental band with one band master and forty-six musicians.

In 1806 the corps of Grenadiers contained two regiments each of two battalions. A battalion now consisted of eight companies of 122 men. The staff was also expanded and there was now three majors, six chefs de battaillon, six adjutant-majors and sous-adjutant-majors, four porte-drapeaux, six brigad ier-tamb ours, the whole being commanded by a colonel.

The two regiments were amalgamated in 1808 to form just one regiment of two battalions. The re-formed 2nd Regiment and the 3rd and 4th regiments also had two battalions of eight companies each.
