The Art of War, Chapter 7: 軍爭 (Manoeuvring)

Chapter 6 was about shaping the contest so that the other side reacts to you. Chapter 7 is about the contest itself: two sides racing for the same position, and what the race costs. It argues that this is the hardest part of command, because gaining an advantage first can also expose you to the most danger.

Like every chapter in this series, it has three parts: the reading, an analysis of what the chapter argues, and how finance professionals can interpret it in their own work. The original text follows the Chinese Wikisource edition of 《孫子兵法》. The Chinese and English explanations are Claude’s own paraphrase.

Reading the chapter

7.1

原文

孫子曰：凡用兵之法，將受命於君，合軍聚衆，交和而舍，莫難於軍爭。軍爭之難者，以迂為直，以患為利。故迂其途，而誘之以利，後人發，先人至，此知迂直之計者也。

中文解說

孫子說：用兵作戰的通則是，將領從君主那裡接受命令，召集軍隊、編組人馬，到與敵軍相對而駐紮，在這整個過程中，沒有比「軍爭」更困難的了。軍爭的困難在於，要把迂迴的路變成直路，把不利的處境變成有利。所以故意繞遠路，再用小利誘導敵人，這樣雖然比敵人晚出發，卻能比敵人先到達，這就是懂得迂直之計的人。

English

From the moment a general receives orders, raises the army and camps opposite the enemy, nothing is harder than the contest for advantage. The difficulty is turning a winding road into a straight one, and a disadvantage into a benefit. Take the longer route, tempt the enemy with some gain, set out after him and still arrive first. That is someone who understands the indirect and the direct.

The key point is that the shortest path is not always the fastest. 軍爭 is commonly read as the struggle to seize a position of advantage before the other side does.

7.2

原文

故軍爭為利，軍爭為危。舉軍而爭利，則不及；委軍而爭利，則輜重捐。

中文解說

所以軍爭既有利，也有危險。如果帶著全軍去爭奪有利的位置，行動遲緩，就趕不上；如果丟下全軍輕裝去爭奪，輜重裝備就會損失。

English

So the contest for advantage brings both gain and danger. Move the whole army to chase it and you arrive too late. Leave the heavy part of the army behind to go faster and you lose the baggage and supplies.

Both choices have a price. The passage sets up the rest of the chapter: speed and completeness pull against each other.

7.3

原文

是故卷甲而趨，日夜不處，倍道兼行，百里而爭利，則擒三軍將，勁者先，疲者後，其法十一而至；五十里而爭利，則蹶上軍將，其法半至；三十里而爭利，則三分之二至。

中文解說

所以如果收起盔甲急行軍，日夜不休息，加倍趕路，走一百里去爭利，三軍的將領都可能被敵人擒獲，強壯的士兵先到，疲弱的落在後面，大約只有十分之一的人能到達；走五十里去爭利，前軍的將領會受挫，大約一半的人能到達；走三十里去爭利，大約三分之二的人能到達。

English

Strip off the armour, march day and night without rest, double the daily distance, and go a hundred miles for the prize. The commanders of all three divisions will be captured. The strong arrive first and the exhausted trail behind, and only about one in ten gets there. At fifty miles, the leader of the vanguard stumbles and about half arrive. At thirty miles, about two-thirds arrive.

The numbers are illustrations of scale, not data. The point is that a forced march loses people in proportion to the distance, and the army that arrives is smaller and weaker than the one that left.

7.4

原文

是故軍無輜重則亡，無糧食則亡，無委積則亡。故不知諸侯之謀者，不能豫交；不知山林、險阻、沮澤之形者，不能行軍；不用鄉導者，不能得地利。

中文解說

所以軍隊沒有輜重就會滅亡，沒有糧食就會滅亡，沒有物資儲備也會滅亡。不了解各諸侯的企圖和謀劃，就不能事先與他們結交；不熟悉山林、險阻、沼澤的地形，就不能行軍；不使用嚮導，就得不到地形的好處。

English

An army without its baggage train is lost. An army without food is lost. An army without stored supplies is lost. Someone who does not know the plans of the neighbouring rulers cannot form alliances in advance. Someone who does not know the mountains, forests, defiles and marshes cannot march. Someone who does not use local guides cannot gain the benefit of the ground.

Three kinds of preparation are named: supply, knowledge of other parties' intentions, and local knowledge. Speed without them is just exposure.

7.5

原文

故兵以詐立，以利動，以分合為變者也。故其疾如風，其徐如林，侵掠如火，不動如山，難知如陰，動如雷震。掠鄉分衆，廓地分利，懸權而動。先知迂直之計者勝，此軍爭之法也。

中文解說

用兵要靠詭詐來成立，靠利益來行動，靠兵力的分散與集中來變化。所以行動快的時候像風，緩慢的時候像森林，進攻劫掠時像火，穩固不動時像山，隱蔽時像陰天一樣難以捉摸，行動起來像雷霆一樣迅猛。掠取鄉邑時要分兵，開拓土地時要分配利益，權衡利害之後才行動。先懂得迂直之計的人獲勝，這就是軍爭的方法。

English

War rests on deception, moves for advantage, and changes by dividing and combining forces. Be as fast as the wind, as calm as a forest, as destructive as fire, as immovable as a mountain, as hard to read as a dark sky, and as sudden as thunder. Divide the troops when plundering villages, share out the gains when taking land, and weigh the situation before moving. The one who first understands the indirect and the direct wins. This is the method of the contest.

The first sentence is the contested one. 詐 is usually translated as deception, though some readers take it to mean not revealing intentions. Either way, the text is describing an army, and Claude does not read it as a licence for misrepresentation in any other setting.

7.6

原文

《軍政》曰：「言不相聞，故為金鼓；視不相見，故為旌旗。」夫金鼓旌旗者，所以一民之耳目也。民既專一，則勇者不得獨進，怯者不得獨退，此用衆之法也。故夜戰多金鼓，晝戰多旌旗，所以變人之耳目也。

中文解說

《軍政》這本書說：「說話聽不到，所以用金鼓；眼睛看不見，所以用旌旗。」金鼓旌旗，是用來統一眾人的視聽的。大家的視聽既然統一，勇敢的人就不能單獨冒進，膽小的人也不能單獨後退，這是指揮大軍的方法。所以夜間作戰多用金鼓，白天作戰多用旌旗，是為了適應環境，改變人們的視聽。

English

The old text Military Administration says that when voices cannot be heard, use gongs and drums, and when eyes cannot see, use banners and flags. These signals unify what everyone hears and sees. Once the troops are unified, the brave cannot advance alone and the timid cannot retreat alone. That is how to handle a large force. So night fighting uses more gongs and drums, and day fighting uses more banners, to suit what people can perceive.

The passage is about shared signals. A large group moves as one only when everyone reads the same cue.

7.7

原文

三軍可奪氣，將軍可奪心。是故朝氣銳，晝氣惰，暮氣歸。故善用兵者，避其銳氣，擊其惰歸，此治氣者也；以治待亂，以靜待嘩，此治心者也；以近待遠，以佚待勞，以飽待饑，此治力者也；無邀正正之旗，無擊堂堂之陣，此治變者也。

中文解說

對於整支軍隊，可以奪取它的士氣；對於將領，可以動搖他的決心。早晨的士氣旺盛，中午逐漸懈怠，傍晚則思歸休息。所以善於用兵的人，避開敵人旺盛的士氣，在他懈怠、思歸時進攻，這是掌握士氣的方法。用自己的嚴整對付敵人的混亂，用自己的沉靜對付敵人的喧嘩，這是掌握心理的方法。用自己靠近戰場對付遠道而來的敵人，用自己的從容對付疲勞的敵人，用自己的飽足對付飢餓的敵人，這是掌握體力的方法。不去攔截旗幟整齊的隊伍，不去攻擊陣容堂堂正正的軍隊，這是掌握應變的方法。

English

An army can lose its morale, and a commander can lose his resolve. Morale is sharp in the morning, slack by midday and set on going home by evening. A skilled commander avoids the enemy when it is sharp and strikes when it is slack or tired. That is managing morale. Meeting disorder with order and clamour with calm is managing the mind. Waiting near for those who come far, waiting rested for the weary and waiting fed for the hungry is managing strength. Not intercepting a well-ordered banner and not attacking a formation that is imposing and sound is managing change.

The common thread is timing. The same force can be strong or weak depending on when it is met.

7.8

原文

故用兵之法，高陵勿向，背丘勿逆，佯北勿從，銳卒勿攻，餌兵勿食，歸師勿遏，圍師必闕，窮寇勿迫，此用兵之法也。

中文解說

所以用兵的原則是：敵人占據高地，不要正面仰攻；敵人背靠山丘，不要迎面進攻；敵人假裝敗退，不要追趕；敵人的精銳部隊，不要硬攻；敵人拋出的誘餌，不要去吞；撤退回國的敵軍，不要阻攔；包圍敵軍時，要留一個缺口；陷入絕境的敵人，不要逼得太緊。這些就是用兵的法則。

English

The rules of war: do not attack uphill. Do not oppose an enemy with a hill at his back. Do not pursue a feigned retreat. Do not attack elite troops. Do not swallow bait. Do not block an army heading home. When you surround an enemy, leave an opening. Do not press a desperate enemy too hard.

Most of these are warnings against acting just because an opening appears. The opening in the encirclement is the most discussed, since it is usually explained as avoiding a fight to the death.

Analysis: what the chapter argues

The hardest part is the race. 7.1 says that nothing is harder than 軍爭 once the army is raised and facing the enemy. The difficulty is that both sides want the same advantage, and the winner is decided by how well each handles the journey, not by the goal.

The indirect route can be the faster one. 7.1 turns a winding road into a straight one and a disadvantage into a benefit. The idea is that the direct path is also the one the enemy expects and defends. Setting out later and arriving first needs the enemy to be distracted by something else, which is why the text adds a lure.

Speed has a price. 7.2 and 7.3 show that going faster means leaving something behind. The figures in 7.3 are illustrations, and what they say is that losses grow with distance and exhaustion, and that the arriving force is weaker than the departing one.

Supply and knowledge come first. 7.4 says that without baggage, food and stores the army is lost. It also says that you cannot march without knowing the ground, you cannot ally without knowing the neighbours’ plans, and you should use local guides.

The meaning of 詐 is contested. 7.5 begins with 兵以詐立. Traditional commentators read it as deception of the enemy. Some modern readers prefer a milder sense of not disclosing your real intent. The chapter then lists contrasting states: fast as wind, calm as a forest, and so on. The takeaway is flexibility and surprise, and the text is about enemy armies.

Large groups need shared signals. 7.6 describes gongs, drums and banners as ways to make everyone see and hear the same thing. This is a statement about coordination, and it is separate from the discussion of deception in 7.5.

Morale and timing are things to manage. 7.7 treats the army’s spirit as something that can be taken away or protected, and describes how it changes across the day. It lists four kinds of management: morale, mind, strength and change. In each case the advice is to wait until the opponent is at a disadvantage.

Restraint is part of the method. 7.8 is a list of things not to do. Several are about not being drawn in by an apparent opening (佯北, 餌兵). Others are about not forcing a desperate opponent to fight to the end (圍師必闕, 窮寇勿迫). The commentary tradition reads the openings as a way to avoid costly last stands, though that explanation is an interpretation and not stated in the text.

How finance professionals can read it

This section is Claude’s interpretation. Sun Tzu wrote about armies, and none of the mappings below are his. Chapter 6 was about initiative. This chapter is about the cost of using it, and about the discipline to avoid acting only because a chance has appeared.

A note on 兵以詐立. The mappings below concern lawful information gathering and posture only. They do not endorse material non-public information, insider trading, misrepresentation, or any breach of confidentiality or law. Every mapping that involves competitive timing, disclosure or dealing with counterparties needs to be checked against securities law, confidentiality agreements and the firm’s compliance rules.

Investing

• The shortest route is not always the fastest. 7.1 can be read as a reminder that the obvious entry, such as the consensus trade, may be crowded. An indirect approach, such as a less visible segment or a longer research path, may reach a better position, but it needs a reason to believe the crowd is looking elsewhere.
• Speed leaves things behind. 7.2 and 7.3 map to rushing a decision. If you move faster than your diligence, something is left behind: the risk review, the liquidity check, the exit plan. Decide in advance what must not be left behind.
• Check supply before the chase. 7.4 can be read as funding, liquidity and margin. A position with a good thesis can still fail if you cannot finance it or hold it through volatility.
• Know the ground. 7.4 on local guides maps to using people with real knowledge of the market, sector or country. Use public sources, expert calls arranged through proper channels and your own research.
• Do not take the bait. 7.8 on 餌兵勿食 and 佯北勿從 is a warning about apparent bargains and sudden price moves. When something looks too easy, ask who benefits from you thinking so.
• Timing of attention. 7.7 observes that the same opponent is stronger or weaker at different times. The analogy is that the same market or counterparty may be more or less receptive depending on conditions. Waiting for the better moment is a legitimate choice.

Raising funds

• A fast process needs prepared materials. 7.2 and 7.3 suggest that rushing a raise without the data room, the financials and the story in order costs more than a short delay. Prepare first, then move quickly.
• Do not leave the baggage behind. In 7.4, the supply train maps to the legal documents, the reporting and the investor updates that must keep pace with the fundraising. A round that closes without them creates problems later.
• Understand investors’ intentions. 7.4 says that without knowing the neighbours’ plans you cannot ally in advance. For fundraising, that means learning what each investor is looking for, their fund timeline and their portfolio constraints, through meetings and public information.
• Shared signals. 7.6 suggests that a syndicate or a board moves better when everyone sees the same information. Give all investors consistent materials and timely updates.
• Disclose accurately. 7.5 should never be read as permission to mislead investors. Offering documents and statements to investors are subject to disclosure and anti-fraud rules, and the company’s counsel should review them.

M&A

• Racing for a target. 7.1 and 7.2 describe the competitive auction. The bidder who moves fastest may win, and may also overpay or skip diligence. Decide what you will not trade away for speed.
• Supply is the financing and the integration plan. 7.4 maps to committed financing, funds for the deal and a plan for what happens after closing. A bid with no funding certainty is moving without supply.
• Know the other parties. 7.4 on neighbours’ plans maps to understanding the target’s board, major shareholders, regulators and other likely bidders from public information and proper channels.
• Keep the key people together. 7.6 on shared signals maps to communication with both teams. Employees from both sides need to hear the same plan, or they act on rumours.
• Beware the apparent opening. 7.8 warns against what looks like a weakness. A target that appears easy to buy may be being sold for a reason that diligence has not yet found.
• Leave the other side a way out. 圍師必闕 and 窮寇勿迫 can be read as leaving a counterparty room to agree. A seller pushed into a corner may walk away, litigate or damage the asset. Negotiating terms that the other side can accept is often more productive than pressing every point.
• Confidentiality. Any attempt to appear unreadable (難知如陰) must stay within confidentiality agreements, takeover rules and disclosure obligations. Keeping your strategy private is lawful. Misleading the market or the counterparty is not.

Across all three

• Name what you will leave behind. Any acceleration drops something. Decide what that is before you start.
• Check supply before speed. Funding, liquidity, people and documents come before the sprint.
• Treat an easy opening as a question. Ask why it is open and who gains if you take it.
• Stay inside the law. Competitive timing and discretion are legitimate. Material non-public information, insider trading, misrepresentation and breaches of confidentiality are not.

Questions to carry into the next chapter

Chapter 8 (九變) takes the next step: knowing when to depart from the standard method, and when the ruler’s instructions or the usual rule should give way to the situation.

• In your current deal or position, what would you leave behind if you had to move twice as fast?
• Which opening looks easiest right now, and who benefits if you take it?
• Where have you been following a standard rule in a situation that no longer fits it?
