The British Cavalry Division has 4 Brigades or 36 Squadrons; 2 _Brigades_ of Horse Artillery--that is, 4 Batteries, or 24 guns; 4 _Field Troops_ of Engineers; and a _Wireless Telegraph Company_ in four sections. It is obvious that by this organization a Brigade can be furnished with all Units it requires for independent action when detached. Cavalry Divisions are furnished with the following Administrative Units: _A Supply Column_; _Field Ambulances_; _Field Post Office_. 2. THE ARMY CORPS MEANING OF THE TERM This word is a somewhat misleading translation of the original French term _Corps d’Armée_, which means one of the bodies of troops forming an army, whereas the English term (which came through the German _Armee Korps_) might be supposed to mean a Corps which is an army in itself. It is now generally shortened to _Corps_. REASON FOR ORGANIZATION BY ARMY CORPS If the Army is very large, there must be an intermediate link in the chain of Command between its Commander and the Divisions, or there would be too many Subordinate Commanders for the Army Commander to direct effectively. This link is provided in the larger armies of the Continent by the _Army Corps_, formed of two or more Infantry Divisions. A similar grouping of some of the Cavalry Divisions into _Cavalry Corps_ may be occasionally found in war. Jomini pointed out (“Art de la Guerre,” Vol. ii., chap, vii.), and Clausewitz (“On War,” Book V., chap, v.) endorsed his view, that, for armies up to 100,000 strong, a _Divisional_ organization was best. This strength represents five or six Divisions, and one or two Cavalry Divisions, which may therefore be considered as the maximum number which an army should comprise, if organized in Divisions only. The advantages of the _Army Corps_ organization of armies are that the Supreme Command is facilitated by there being fewer Units to direct, and that a _few_ important Commanders can be better selected than a number. This organization also provides a large independent force, under a Senior Commander, available for any special mission. There were periods in the South African War when the temporary employment of several Divisions for a special purpose would have been more effective had they formed a permanent organization like an Army Corps, with its own Commander and Staff. At the same time it is undoubtedly true that, except when unavoidable, the addition of another step in the gradation of Command is undesirable for many reasons. It is wasteful in Staff; it tends to delay the transmission of Orders; and the large strength of the Army Corps gives their Commanders so much importance as to lead to considerable independence in their action, which may weaken the Supreme Command.
