The strength of the British Expeditionary Force is practically that of three Cavalry Divisions and three Army Corps of the German Army. The former comprises 75 Battalions, the equivalent of nearly 23 Regiments of Mounted Troops, and 492 guns; the latter, 75 Battalions, 24 Cavalry Regiments, and 468 guns. But the British Force is organized so as to be more flexible, and to facilitate and strengthen the Supreme Command. It is _more flexible_ from the greater number of Subordinate Commands. It _facilitates Command_ by having two links fewer in the chain of Command--the Army Corps and the Regiment. It _strengthens Command_ by not having any Subordinate Commander of the importance of the German Army Corps Commander to reckon with--a point emphasized by Clausewitz. FACILITY OF SUBDIVISION The British organization is so planned that the Force can be readily divided, when required, into two Armies, each of which can be provided with its proportion of Strategic and Protective Cavalry, and of Army Troops, without disorganizing and rearranging those Formations. This principle has been carried throughout the Force. Thus, the _Cavalry Division_ can supply any detached _Brigade_ with the _Divisional Troops_ required--namely, a Battery of Horse Artillery, a Field Troop of Engineers, a Section of the Wireless Telegraph Company, a Field Ambulance, and a Company of A.S.C. to form the Brigade T. and S. Column, there being one of each of these _Divisional Units_ for each Brigade to be detached. Similarly, the _Cavalry Brigade_ can detach one of its _Regiments_ provided with Sections from the Field Troop of Engineers, the Field Ambulance, and the A.S.C. Company, so as to be self-contained. In exactly the same manner, the _Division_ of Infantry can at any time detach a _Brigade_ provided with its due proportion of all Arms and Administrative Services, without confusion and delay. The _Infantry Brigade_, also, can detach _Battalions_ equally self-contained; and the _Artillery Brigade_ can allot a Section of its Ammunition Column to any _Battery_ which it may be desirable to detach. STAFF The following principles have been adopted: Separation of the General Staff from the Branches of the Staff charged with Routine and Administrative work, and making the latter Branches subordinate to the General Staff for their general direction, while independent in their working. This matter has been discussed in Chapter VI. Reduction of the numbers attached to General Head-Quarters, by relegating most of the Directors of the Administrative Services to the L. of C. This is very desirable in the case of the Services which work on the L. of C., in order that the Directors may be in intimate touch with their work. As a rule, only the Directors of Army Signals, Supplies, Transport, and Medical Services will accompany General Head-Quarters at the front. CAVALRY ORGANIZATION
