《尉缭子·武议》
将帅击鼓指挥军队，使其在危难情况下与敌决战，当两军短兵相接的时候，如果指挥得当，就会建立功名，如果指挥不当，就会身死亡。
接兵角刃，鼓之而当，则赏功立名；鼓之而不当，则身死国亡。
Generals beat drums to command the troops, making them fight a decisive battle with the enemy in times of crisis. When the two armies engage in close combat, if the command is proper, one will establish meritorious achievements; if the command is improper, one will die.
