It is imperative to contest all factions for complete victory, so the army is not garrisoned and the profit can be total. This is the law of strategic siege.

Know the enemy, know yourself; your victory will never be endangered. Know the ground, know the weather; your victory will then be total.

Set the troops to their tasks without imparting your designs.

Weigh the situation, then move.

So it is that good warriors take their stance on ground where they cannot lose, and do not overlook conditions that make an opponent prone to defeat.
