"When the enemy has made a plan of attack against us, we must anticipate him by delivering our own attack first."]
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;
[When he is already at full strength.]

The preparation of mantlets, movable shelters, and various implements of war, will take up three whole months;
[It is not quite clear what the Chinese word, here translated as "mantlets", described. Ts’ao Kung simply defines them as "large shields," but we get a better idea of them from Li Ch’uan, who says they were to protect the heads of those who were assaulting the city walls at close quarters.
