That _relative advantage in Mobility_ expressed by the situation of the
Strategic Front upon the Strategetic Center is materially manifested
upon the Chess-board by Kindred Chess-pieces posted upon that great
central diagonal which extends towards the Objective Plane. Such
advantage determines those points which should be occupied in the proper
development of the front so posted; and consequently designates the
direction and location of that battlefield upon which the kindred army
may concentrate in overwhelming force, despite all possible resistance by
the enemy.
