He cautions against using open warfare. The object of warfare is the defeat and disruption, not necessarily the slaughter, of the enemy. In fact, the author of the Strategikon counsels against using the technique of encirclement because it would encourage the enemy to remain and to risk battle. He advises that it is better to allow an encircled enemy to flee to avoid forcing him to take a life-or-death stand, which would be costly in casualties to the encircling party. There is no more eloquent testimony to the desire to avoid decisive battle. [17]
[17. Ibid. 8.2.92.]
The author of the Strategikon recommends that the general should command his army "using tactics and strategy alertly." [18]
[18. Ibid. pr. -16]
He adds that, "By strategy, using opportunities and places, and by means of sudden undertakings in order to deceive the enemy, it is possible to reach one's goal without open battles." [19]
