Nothing is more important in war than unity in command. When, therefore, you are carrying on hostilities against a single power only, you should have but one army acting on one line and led by one commander.

It is contrary to the usages of war to cause your parks or heavy artillery to enter a defile, the opposite extremity of which is not in your possession; since, in the event of a retreat". they will embarrass you and be lost. They ought to be left in position, under a suitable escort, until yoU have made yourself master of thetermination of the defile.

A military maxim, which ought never to be neglected, is to assemble your cantonments at the point which is most remote and best sheltered from the enemy, especially when he makes his appearance unexpectedly. You will then have time to unite the whole army before he can attack you.

The art of war consists in bringing to bear with an inferior army a superiority of force at the point at which one attacks or is attacked.

The art of war consists in being always able, even with an inferior army, to have stronger forces than the enemy at the point of attack or the point which is attacked.

Plans of campaign may be infinitely modified according to the circumstances, the genius of the commander, the quality of the troops and the topography of the theater of war.
