Thus we hear of a decisive skilful march, allusion being thereby made to those combat-combinations to which these marches led.

This substitution of ideas is too natural and conciseness of expression too desirable to call for alteration, but still it is only a condensed chain of ideas in regard to which we must never omit to bear in mind the full meaning, if we would avoid falling into error.
We fall into an error of this description if we attribute to strategical combinations a power independent of tactical results.

We read of marches and manoeuvres combined, the object attained, and at the same time not a word about combat, from which the conclusion is drawn that there are means in War of conquering an enemy without fighting.

The prolific nature of this error we cannot show until hereafter.
But although a march can be regarded absolutely as an integral part of the combat, still there are in it certain relations which do not belong to the combat, and therefore are neither tactical nor strategic.

To these belong all arrangements which concern only the accommodation of the troops, the construction of bridges, roads, &c.
