The Staff of the Grande Armée was known as the Imperial Headquarters and was divided into two major sections: Napoleon's Military Household and the Army General Headquarters.
The Maison Militaire de l'Empereur (Military Household of the Emperor) was Napoleon's personal military staff and included the department of aides-de-camp (ADCs), orderly officers (until 1809), the Emperor's Cabinet with the Secretariat, a department that collected intelligence about the enemy using spies and the topographical department [REF].
