The T‘u Shu has 是謂巧於成事, and yet another reading, mentioned by Ts‘ao Kung, is 巧攻成事. Capt. Calthrop omits this sentence, after having thus translated the two preceding: “Discover the enemy’s intentions by conforming to his movements. When these are discovered, then, with one stroke, the general may be killed, even though he be one hundred leagues distant.”
63. 是故政舉之日夷關折符無通其使
On the day that you take up your command,
政舉 does not mean “when war is declared,” as Capt. Calthrop says, nor yet exactly, as Ts‘ao Kung paraphrases it, 謀定 “when your plans are fixed,” when you have mapped out your campaign. The phrase is not given in the P‘ei Wên Yün Fu. There being no causal connection discoverable between this and the preceding sentence, 是故 must perforce be left untranslated.
block the frontier passes,
夷 is explained by Mei Yao-ch‘ên as 滅塞.
destroy the official tallies,
The locus classicus for these tallies is Chou Li, XIV. fol. 40 (Imperial edition): 門關用符節貨賄用璽節道路用旌節. The generic term thus appears to be 節, 符 being the special kind used at city-gates and on the frontier. They were tablets of bamboo or wood, one half of which was issued as a permit or passport by the official in charge of a gate (司門 or 司關. Cf. the 封人 “border-warden” of Lun Yü III. 24, who may have had similar duties.) When this half was returned to him, within a fixed period, he was authorised to open the gate and let the traveller through.
and stop the passage of all emissaries.
Either to or from the enemy’s country.
64. 厲於廊廟之上以誅其事
Be stern in the council-chamber,
Show no weakness, and insist on your plans being ratified by the sovereign. 廊廟 indicates a hall or temple in the Palace. Cf. I. § 26. It is not clear if other officers would be present. Hardly anything can be made of 勵, the reading of the standard text, so I have adopted Tu Mu’s conjecture 厲, which appears in the T‘u Shu.
so that you may control the situation.
Ts‘ao Kung explains 誅 by 治, and Ho Shih by 責成. Another reading is 謀, and Mei Yao-ch‘ên, adopting this, understands the whole sentence to mean: Take the strictest precautions to ensure secrecy in your deliberations. Capt. Calthrop glides rather too smoothly over the rough places. His translation is: “conduct the business of the government with vigilance.”
65. 敵人開闔必亟入之
If the enemy leaves a door open, you must rush in.
This looks a very simple sentence, yet Ts‘ao Kung is the only commentator who takes it as I have done. Mêng Shih, followed by Mei Yao-ch‘ên and Chang Yü, defines 開闔 as 間者 “spies,” and makes 入 an active verb: “If spies come from the enemy, we must quickly let them in.” But I cannot find that the words 開闔 have this meaning anywhere else. On the other hand, they may be taken as two verbs, 或開或闔, expressing the enemy’s indecision whether to advance or retreat, that being the best moment to attack him. [Cf. Tao Tê Ching, chap. X: 天門開闔能爲雌乎; also Li Chi, 曲禮, I. ii. 25.] It is not easy to choose between this and Ts‘ao Kung’s explanation; the fact that 敵人開戶 occurs shortly afterwards, in § 68, might be adduced in support of either. 必 must be understood in the sense of 宜 or 當. The only way to avoid this is to put 開闔 between commas and translate: “If we leave a door open, the enemy is sure to rush in.”
66. 先其所愛微與之期
Forestall your opponent by seizing what he holds dear,
Cf. supra, § 18.
and subtly contrive to time his arrival on the ground.
Capt. Calthrop hardly attempts to translate this difficult paragraph, but invents the following instead: “Discover what he most values, and plan to seize it.” Ch‘ên Hao’s explanation, however, is clear enough: 我若先奪便地而敵不至雖有其利亦奚用之是以欲取 其愛惜之處必先微與敵人相期誤之使必至 “If I manage to seize a favourable position, but the enemy does not appear on the scene, the advantage thus obtained cannot be turned to any practical account. He who intends, therefore, to occupy a position of importance to the enemy, must begin by making an artful appointment, so to speak, with his antagonist, and cajole him into going there as well.” Mei Yao-ch‘ên explains that this “artful appointment” is to be made through the medium of the enemy’s own spies, who will carry back just the amount of information that we choose to give them. Then, having cunningly disclosed our intentions, 我後人發先人至 “we must manage, though starting after the enemy, to arrive before him” (VII. § 4). We must start after him in order to ensure his marching thither; we must arrive before him in order to capture the place without trouble. Taken thus, the present passage lends some support to Mei Yao-ch‘ên’s interpretation of § 47.
67. 踐墨隨敵以決戰事
Walk in the path defined by rule,
墨 stands for 繩墨 “a marking-line,” hence a rule of conduct. See Mencius VII. 1. xli. 2. Ts‘ao Kung explains it by the similar metaphor 規矩 “square and compasses.” The baldness of the sentiment rather inclines me to favour the reading 剗 adopted by Chia Lin in place of 踐, which yields an exactly opposite sense, namely: “Discard hard and fast rules.” Chia Lin says: 惟勝是利不可守以繩墨而爲 “Victory is the only thing that matters, and this cannot be achieved by adhering to conventional canons.” It is unfortunate that this variant rests on very slight authority, for the sense yielded is certainly much more satisfactory. Napoleon, as we know, according to the veterans of the old school whom he defeated, won his battles by violating every accepted canon of warfare.
and accommodate yourself to the enemy until you can fight a decisive battle.
The last four words of the Chinese are omitted by Capt. Calthrop. Tu Mu says: 隨敵人之形若有可乘之勢則出而決戰 “Conform to the enemy’s tactics until a favourable opportunity offers; then come forth and engage in a battle that shall prove decisive.”
