_(major-general des logis,)_ who was formerly charged with directing the
marches, encampments, and lodging of the troops. It has been still
further extended by recent military writers, and many of them now regard
logistics as a distinct and important branch of the art.
We shall here consider logistics as including the military duties
ordinarily attributed to the pay, subsistence, clothing, medical,
hospital, and transportation departments; in fine, of all the civil and
civico-military corps of the army. We shall therefore discuss under this
head, the preparation of all the necessary materials for fitting out
troops for a campaign and for putting them in motion; the regulating of
marches, convoys, the means of transport for provisions, hospitals,
munitions, and supplies of all kinds; the preparation and protection of
magazines; the laying out of camps and cantonments; in fine, every thing

must receive instructions directly from the chief of the staff of the
army, who will have the general direction of every thing connected with
logistics. Before commencing the operations of the campaign, or

this officer should satisfy himself respecting the condition of the
various materials belonging to the different departments of the
army;--the horses and horse equipments, carriages, caissons, ponton and
artillery equipages, siege equipages, moveable hospitals, engineer and
artillery utensils, clothing, and munitions of all kinds; he must supply
whatever may be wanting, and provide means for the transportation of
every thing.
_Subsistence_.--The art of subsisting troops during active operations in
a hostile country, is one of the most difficult subjects connected with
war; and it is a question well worthy of study, both for the statesman
and the warrior, how Darius and Xerxes, Philip and Alexander, in ancient
times--and the Greek emperors and the barbarians--and, later still, the
crusaders of the middle ages, contrived to support the immense
