An army unsupplied with grain and other necessary provisions will be vanquished without striking a blow.
A general whose troops are superior both in number and bravery should engage in the oblong square, which is the first formation.
He who judges himself inferior should advance his right wing obliquely against the enemy's left. This is the second formation.
If your left wing is strongest, you must attack the enemy's right according to the third formation.
The general who can depend on the discipline of his men should begin the engagement by attacking both the enemy's wings at once, the fourth formation.
He whose light infantry is good should cover his center by forming them in its front and charge both the enemy's wings at once. This is the fifth formation.
