“The city is small and well fortified; even if I succeed in taking it, it will be no great feat of arms; whereas if I fail, I shall make myself a laughingstock. It is a great mistake to waste men in taking a town when the same expenditure of soldiers will gain a province.”
There are armies that must not be attacked, positions that must not be contested, commands of the sovereign that must not be obeyed.
The general who thoroughly understands the advantages that accompany variation of tactics knows how to handle his troops. The general who does not understand these may be well acquainted with the configuration of the country, yet he will not be able to turn his knowledge to practical account.
In A.D. 404, Liu Yu pursued the rebel Huan Hsuan up the Yangtze and fought a naval battle with him at the island of Ch’eng-hung. The loyal troops numbered only a few thousand, while their opponents were in great force. But Huan Hsuan, fearing the fate that was in store for him should he be overcome, had a light boat made fast to the side of his war junk, so that he might escape, if necessary, at a moment’s notice. The natural result was that the fighting spirit of his soldiers was utterly quenched, and when the loyalists made an attack from windward with fireships, all striving with the utmost ardor to be first in the fray, Huan Hsuan’s forces were routed, had to burn all their baggage, and fled for two days and nights without stopping.
In the wise leader’s plans, considerations of advantage and of disadvantage will be blended together. If our expectation of advantage be tempered in this way, we may succeed in accomplishing the essential part of our schemes. If, on the other hand, in the midst of difficulties we are always ready to seize an advantage, we may extricate ourselves from misfortune.
Reduce the hostile chiefs by inflicting damage on them; make trouble for them, and keep them constantly engaged; hold out specious allurements, and make them rush to any given point.
Chia Lin adds to this section several ways of inflicting this injury: “Entice away the enemy’s best and wisest men, so that he may be left without counselors. Introduce traitors into his country, that the government policy may be rendered futile. Foment intrigue and deceit, and thus sow dissension between the ruler and his ministers. By means of every artful contrivance, cause deterioration among his men and waste of his treasure. Corrupt his morals by insidious gifts leading him into excess. Disturb and unsettle his mind by presenting him with lovely women.”
The art of war teaches us to rely not on the likelihood of the enemy’s not coming, but on our own readiness to receive him; not on the chance of his not attacking, but rather on the fact that we have made our position unassailable.
There are five dangerous faults that may affect a general, of which the first two are: recklessness, which leads to destruction; and cowardice, which leads to capture.
Next there is a delicacy of honor, which is sensitive to shame; and a hasty temper, which can be provoked by insults.
Yao Hsiang, when opposed in A.D. 357 by Huang Mei, Teng Ch’iang, and others, shut himself up behind his walls and refused to fight. Teng Ch’iang said: “Our adversary is of a choleric temper and easily provoked; let us make constant sallies and break down his walls, then he will grow angry and come out. Once we can bring his force to battle, it is doomed to be our prey.” This plan was acted upon, Yao Hsiang came out to fight, was lured on as far as San-yuan by the enemy’s pretended flight, and finally attacked and slain.
The last of such faults is oversolicitude for his men, which exposes him to worry and trouble, for in the long run the troops will suffer more from the defeat, or at best, the prolongation of the war, which will be the consequence.
These are the five besetting sins of a general, ruinous to the conduct of war. When an army is overthrown and its leader
