If I am able to determine the enemy's dispositions while at the same time I conceal my own, then I can concentrate and he must divide.

The skillful leader subdues the enemy's troops without any fighting.

Be the first to seize intersecting ground, that is ground which lies the intersections of borders or intersections of main thoroughfares of commerce and travel. Your occupation of it gives you access to all who border it and all who would covet it. On intersecting ground, if you establish alliances you are safe, if you lose alliances you are in peril.

He who knows his enemy and himself well will not be defeated easily.

Order or disorder depends on organisation and direction; courage or cowardice on circumstances; strength or weakness on tactical dispositions.

When the enemy is at ease, be able to weary him; when well fed, to starve him; when at rest, to make him move. Appear at places to which he must hasten; move swiftly where he does not expect you.

Attack him where he is unprepared, appear where you are not expected.
