上兵は謀を伐つ、 其の次ぎは交を伐つ、 其の次は兵を伐つ、 其の下は城を攻む。 攻城の法は、已むを得ざるが為めなり。
上兵伐谋，其次伐交，其次伐兵，其下攻城；攻城之法为不得已。
Thus the highest form of generalship is to balk the enemy’s plans; the next best is to prevent the junction of the enemy’s forces; the next in order is to attack the enemy’s army in the field; and the worst policy of all is to besiege walled cities.
