_Advantage in Position with the Column of Manoeuvre_ indicates the opportunity to engage in a victorious Logistic Grand Battle against the adverse Formation by Grand Columns. LEAST FAVORABLE ADVERSE CONDITION That _relative advantage in Time_ expressed by restrictions of the adversary’s choice of movements at his turn to play, is materially manifested upon the Chess-board by Feints operated by Kindred Chess-pieces against adverse vital points; and such advantage of the Initiative dictates the next move of the opposing army. The _advantage of the Initiative_ determines which of the adverse corps d’armee may and may not move. The material expression of this advantage always is a Feint by a Kindred Corps against a vital point either occupied or unoccupied, which necessitates that upon his next move, the enemy either evacuate, support, cover or sustain the post so menaced. Such feint, therefore, restricts the move of the enemy to those of his corps as are able to obviate the threatened loss and proportionately reduces the immediate activity of his army. RELATIVE ADVANTAGES IN LOCATION _“It is only the force brought into action that avails in battles and campaigns--the rest does not count.”--Napoleon._ _The distance which separates opposing Corps d’armee always modifies the values of the Prime Strategetic Means._ Hence in the making of Grand Reconnaissance, it is next in sequence to determine whether the Chess-pieces are: I. In Contact. II. In Presence. III. At Distance. Corps d’armee are _in Contact_ with each other whenever their logistic radii intersect; or, their radii offensive and the corresponding adverse radii defensive are opposed to each other. Corps d’armee are _in Presence_ whenever the posts which they occupy are contained within the same Strategic front, the same Strategetic Horizon, or are in communication with their corresponding posts of mobilization, development, or manoeuvre. Corps d’armee are _at Distance_ when the posts which they occupy are not in communication with Kindred Corps d’armee posted upon the strategic front adopted, or with posts of mobilization or development contained within the corresponding Primary Base of Operations, or, within the True Strategetic Horizon. REQUISITES FOR SUCCESSFUL CAMPAIGNING Every Campaign, whether upon the surface of the Earth or upon the Chess-board is decided and usually is terminated by a Grand Battle. Those movements of opposing Grand Columns, whereby such decisive conflict is brought about under circumstances which ensure victory, by reason of superior advantages in Strategetic Means, are termed Grand Manoeuvres; and a proper series of Grand Manoeuvres, combined with their corresponding feints, strategems, ambuscades and minor battles, the whole terminated by a resulting Grand Battle, is termed a Grand Operation.
