by the errors and divisions of his generals.
To gain a battle, each arm must be advantageously posted, and have the means of engaging its front and in flank. The wings must be protected by natural obstacles, where these present themselves, or by having recourse when necessary to the aid of art.
The troops must be able to assist each other without confusion, and care must be taken that the broken corps do not fall back upon, and throw the rest into disorder.
Above all, the intervals between the different corps must be sufficiently small to prevent the enemy from penetrating between them, for in that case you would be obliged to employ your reserves, and run the risk of being entirely overwhelmed.
Sometimes victory is obtained by creating a diversion in the middle of a battle, or even by depriving the soldier of all hope of retreat, and placing him in a situation where he is reduced to the necessity either to conquer or die.
