He will win who, prepared himself, waits to take the enemy unprepared.

He will win who has military capacity and is not interfered with by the sovereign. 245

Hence the saying: If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. 247 If you know neither the enemy nor yourself, you will succumb in every battle. 248
