A 'commissariat' is the department of an
army charged with the provision of supplies, both food and forage, for the troops. The supply of military stores such as
ammunition is not included in the duties of a commissariat. In almost every army the duties of transport and supply are performed by the same corps of departmental troops.
In the
Major General's Song in
Pirates of Penzance by
Gilbert and Sullivan, the Major-General hopes to someday know 'precisely what is meant by 'commissariat'' (satirizing the 19th century British officers' lack of concrete military knowledge).
