[The remainder of the chapter, quoted in part on pp. [141]–146, outlines the extension of Great Britain’s trade and sea power during the seventeenth and eighteenth centuries.—Editor.]
4. Definition of Terms[[20]]
Strategy, Tactics, Logistics
“Strategy,” says Jomini, speaking of the art of war on land, “is the art of making war upon the map, and comprehends the whole theater of warlike operations. Grand tactics is the art of posting troops upon the battlefield, according to the accidents of the ground; of bringing them into action; and the art of fighting upon the ground in contradistinction to planning upon a map. Its operations may extend over a field of ten or twelve miles in extent. Strategy decides where to act. Grand tactics decides the manner of execution and the employment of troops,” when, by the combinations of strategy, they have been assembled at the point of action.
... Between Strategy and Grand Tactics comes logically Logistics. Strategy decides where to act; Logistics is the act of moving armies; it brings the troops to the point of action and controls questions of supply; Grand Tactics decides the methods of giving battle.
5. Fundamental Principles[[21]]
Central Position, Interior Lines, Communications
The situation here used in illustration is taken from the Thirty Years’ War, 1618–1648, in which the French House of Bourbon opposed the House of Austria, the latter controlling Spain, Austria, and parts of Germany. France lay between Spain and Austria; but if Spain commanded the sea, her forces could reach the field of conflict in central Europe either by way of Belgium or by way of the Duchy of Milan in northern Italy, both of which were under her rule.
[The upper course of the Danube between Ulm and Ratisbon is also employed to illustrate central position, dominating the great European theater of war north of the Alps and east of the Rhine.—Editor.]
The situation of France relatively to her two opponents of this period—Spain and Austria—illustrates three elements of strategy, of frequent mention, which it is well here to name and to define, as well as to illustrate by the instance before you.
