Unhappy is the fate of one who tries to win his battles and succeed in his attacks without cultivating the spirit of enterprise; for the result is wa… - Sun Tzu

Violent language and driving forward as if to the attack are signs that he will retreat.

When the common soldiers are too strong and their officers too weak, the result is INSUBORDINATION.

21. If he is secure at all points, be prepared for him. If he is in superior strength, evade him. 22. If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant. [Wang Tzu, quoted by Tu Yu, says that the good tactician plays with his adversary as a cat plays with a mouse, first feigning weakness and immobility, and then suddenly pouncing upon him.] 23. If he is taking his ease, give him no rest. [This is probably the meaning though Mei Yao-ch’en has the note: “while we are taking our ease, wait for the enemy to tire himself out.” The YU LAN has “Lure him on and tire him out.”] If his forces are united, separate them. [Less plausible is the interpretation favored by most of the commentators: “If sovereign and subject are in accord, put division between them.”] 24. Attack him where he is unprepared, appear where you are not expected. 25. These military devices, leading to victory, must not be divulged beforehand. 26. Now the general who wins a battle makes many calculations in his temple ere the battle is fought. [Chang Yu tells us that in ancient times it was customary for a temple to be set apart for the use of a general who was about to take the field, in order that he might there elaborate his plan of campaign.] The general who loses a battle makes but few calculations beforehand. Thus do many calculations lead to victory, and few calculations to defeat: how much more no calculation at all! It is by attention to this point that I can foresee who is likely to win or lose.
