He should strike the enemy when the latter's army is under troubles or is furiously attacked; or he who has secured a favourable position may strike the enemy entangled in an unfavourable position. Or he who possesses control over the elements of his own state may, through the aid of the enemy's traitors, enemies and inimical wild tribes, make a false impression of his own defeat on the mind of the enemy who is entrenched in a favourable position, and having thus dragged the enemy into an unfavourable position, he may strike the latter. When the enemy's army is in a compact body, he should break it by means of his elephants; when the enemy has come down from its favourable position, following the false impression of the invader's defeat, the invader may turn back and strike the enemy's army, broken or unbroken. Having struck the front of the enemy's army, he may strike it again by means of his elephants and horses when it has shown its back and is running away. When frontal attack is unfavourable, he should strike it from behind; when attack on the rear is unfavourable, he should strike it in front; when attack on one side is unfavourable, he should strike it on the other.
