蘇秦說齊閔王曰：「臣聞用兵而喜先天下者憂，約結而喜主怨者孤。夫後起者藉也，而遠怨者時也。是以聖人從事，必藉於權而務興於時。夫權藉者，萬物之率也；而時勢者，百事之長也。故無權籍，倍時勢，而能事成者寡矣。

 

Su Qin[1] exercised his persuasions on King Min of Qi[2], saying, "Your servant has heard that those who deploy their troops because they take pleasure in being preeminent within All-Under-Heaven will come to grief, and that those who make covenants because they take pleasure in fostering grudges will be left isolated. Those who attack only after being attacked maintain their reserves; those who eschew resentment meet with opportunities. This being so, when the wise pursue their affairs, they inevitably rely upon the momentum of the situation and work according to the spirit of the age. When you accumulate momentum, then the ten thousand things are yours to command; when you follow the impetus of the times, then you are the master of all your affairs. Conversely, those who do not rely upon the momentum of the situation and turn their backs on the spirit of the age, but are able to bring their affairs to a successful conclusion are few. 

​

「今雖干將、莫邪，非得人力，則不能割劌矣。堅箭利金，不得弦機之利，則不能遠殺矣。矢非不銛，而劍非不利也，何則？權藉不在焉。何以知其然也？昔者趙氏襲衛，車舍人不休傅，衛國城割平，衛八門土而二門墮矣，此亡國之形也。衛君跣行，告溯於魏。魏王身被甲底劍，挑趙索戰。邯鄲之中騖，河、山之間亂。衛得是藉也，亦收餘甲而北面，殘剛平，墮中牟之郭。衛非強於趙也，譬之衛矢而魏弦機也，藉力魏而有河東之地。趙氏懼，楚人救趙而伐魏，戰於州西，出梁門，軍舍林中，馬飲於大河。趙得是藉也，亦襲魏之河北燒棘溝，墜黃城。故剛平之殘也，中牟之墮也，黃城之墜也，棘溝之燒也，此皆非趙、魏之欲也。然二國勸行之者，何也？衛明於時權之藉也。今世之為國者不然矣。兵弱而好敵強，國罷而好眾怨，事敗而好鞠之，兵弱而憎下人也，地狹而好敵大，事敗而好長詐。行此六者而求伯，則遠矣。

 

Now even if you have a sword like Gan Jiang[3] or Mo Ye[4], without someone strong to wield it you will be unable to cut or injure anyone. Even with the sturdiest and sharpest arrows, if you do not have a bowstring or a trigger[5], then you will be able to kill no one from afar. It is not that the arrows have no points or that the sword is not sharp, so why is it? Because the momentum is not present. How do I know this is true? In the past, when the House of Zhao raided Wey, itspeople slept in their chariots, and they travelled without rest[6]. They fortified Gangping[7]; eight of the gates to the Wey capital were blocked with earth and two were destroyed. Thus, Wey had the air of a doomed state. The Lord of Wey[8] went barefoot to tell his troubles in Wei[9]. The King of Wei[10] put on his armour and strapped on his sword[11], to take advantage of the momentum of the situation, gathered up its remaining troops, and turned northwards, destroying Gangping and razing the suburbs of Zhongmu[14]. Wey lacked[15] the strength of Zhao, but Wey may be compared to an arrow and Wei to a bow. Wey recruited the strength of Wei[16] and acquired land East of the Yellow River. The House of Zhao was afraid, and Chu's partisans assisted them by attacking Wei, joining battle at Zhouxi[17], entering through the gates of Liang[18], resting their troops at Linzhong[19] and watering their horses at the Yellow River. Zhao took advantage of the momentum of the situation, and raided Wei's lands North of the Yellow River, burning Jipu[20] and destroying Huangcheng[21]. Thus, Zhao and Wei did not originally desire the destruction of Gangping, the razing of Zhongmu, the fall of Huangcheng[22] and the burning of Jipu; nevertheless, both states advanced, why was this? Wey understood the spirit of the age and relied upon its momentum. Those who manage states in the modern world are not like this. Their troops are weak, but they like to believe themselves equal to the strong. Their states are exhausted, but they court popular resentment. Their plans fail, and they cling to them. When their troops are weak they blame it on their underlings[23]. When their lands shrink they still relish facing down larger enemies. When their enterprises fail they prolong the agony with trickery. They follow these six courses and seek hegemony, while moving ever further from achieving it. 

​

「臣聞善為國者，順民之意，而料兵之能，然後從於天下。故約不為人主怨，伐不為人挫強。如此，則兵不費，權不輕，地可廣，欲可成也。昔者，齊之與韓、魏伐秦、楚也，戰非甚疾也，分地又非多韓、魏也，然而天下獨歸咎於齊者，何也？以其為韓、魏主怨也。且天下遍用兵矣，齊、燕戰，而趙氏兼中山，秦、楚戰韓、魏不休，而宋、越專用其兵。此十國者，皆以相敵為意，而獨舉心於齊者，何也？約而好主怨，伐而好挫強也。

 

Your servant has heard he who manages the state skilfully tracks the thoughts of his people and measures the capacity of his troops. Only then does he seek allies in All-Under-Heaven. Thus, in making agreements he does not cherish others' grudges and his strength will not be worn out by launching attacks on others' behalf. Thus he does not waste his troops or or deplete his power, and can to expand his territories and achieve his desires. In the past, when Qi joined Han and Wei, it was in order to attack Qin and Chu[24]. The fight involved no great effort on Qi's part, and Qi arrogated less territory to itself than Han or Wei. Nevertheless, All-Under-Heaven blamed only Qi for it. Why was this? Because Qi had taken up a grudge belonging to Han and Wei, and everyone in All-Under-Heaven then mobilised their troops. Qi was fighting Yan and the House of Zhao was busy unifying Zhongshan with its own state; Qin and Chu were fighting Han and Wei relentlessly, and Song and Yue had committed all their troops to the fray. All of these ten states shared mutual enmities, and yet the one thing that could unite their minds was their attitude towards Qi. Why? Because it liked to foster grudges through its alliances, and to wear out its strength with its attacks.

​

「且夫強大之禍，常以王人為意也；夫弱小之殃，常以謀人為利也。是以大國危，小國滅也。大國之計，莫若後起而重伐不義。夫後起之籍與多而兵勁，則事以眾強適罷寡也，兵必立也。事不塞天下之心，則利必附矣。大國行此，則名號不攘而至，伯王不為而立矣。小國之情，莫如僅靜而寡信諸侯。僅靜，則四鄰不反；寡信諸侯，則天下不賣。外不賣，內不反，則檳禍朽腐而不用，幣帛矯蠹而不服矣。小國道此，則不祠而福矣，不貸而見足矣。故曰：祖仁者王，立義者伯，用兵窮者亡。何以知其然也？昔吳王夫差以強大為天下先，強襲郢而棲越，身從諸侯之君，而卒身死國亡，為天下戮者，何也？此夫差平居而謀王，強大而喜先天下之禍也。昔者萊、莒好謀，陳、蔡好詐，莒恃越而滅，蔡恃晉而亡，此皆內長詐，外信諸侯之殃也。由此觀之，則強弱大小之禍，可見於前事矣。

"When large and strong states suffer misfortunes, it is inevitably because they have hegemonic ambitions. When[25] small and weak states suffer calamities, it is inevitably because their strategists are seeking profit. These things put large states at risk and extinguish small states. For a large state, no strategy can match that of waiting to strike second and then attacking the unjust aggressor with even greater force. When you move second, you will be able to rely upon numerous treaties and well-conditioned troops, and, this being so[26], you will be able to use your manifold strengths to subdue a diminished enemy[27]. Your troops will certainly prevail[28]. If the way in which you pursue your affairs does not harden the hearts of the lords of All-Under-Heaven against you, then you will certainly profit. When large states proceed thus their fame grows inexorably, and hegemony is established with no effort. In the position of a small state, nothing is better than remaining quiescent[29] and expecting little of the feudal lords. If you remain quiescent, then none of your neighbours will turn against you; if you expect little of the feudal lords, then you will never be betrayed by All-Under-Heaven. If those far away cannot betray you, and those nearby cannot oppose you, your food stockpiles will rot before you can use them and your armour will be motheaten before it is ever worn[30]. If a small state follows this path, then without needing to pray to the ancestors it will grow prosperous, and without borrowing it will see itself become self-sufficient. Therefore I say that those who foster benevolence became kings, and those who establish justice became hegemons, while those who squander their troops are wiped out. How do I know this to be so? In the past, King Fuchai of Wu[31] sought to use his state's size and strength to achieve pre-eminence in All-Under-Heaven, raiding[32] Ying[33] and occupying Yue. He led the feudal lords in person, but ended up dead with his state extinguished, eradicated by All-Under-Heaven. Why was this? It was because Fuchai had peace at home but plotted to become a hegemon. His state was large and strong and yet he took pleasure in creating trouble within All-Under-Heaven unprovoked.  In the past, Lai[34] and Ju[35] enjoyed plotting; Chen[36] and Cai[37] enjoyed in deception. Ju relied upon Yue and was wiped out; Cai relied upon Jin and was extinguished. They may have been great liars at home, but they trusted the feudal lords abroad and met with calamity. From this perspective, one can see that the troubles of states strong and weak, large and small, can be foreseen from their past affairs.

「語曰：『麒驥之衰也，駑馬先之；孟賁之倦也，女子勝之。』夫駑馬、女子，筋骨力勁，非賢於騏驥、孟賁也。何則？後起之藉也。今天下之相與也不並滅，有而案兵而後起，寄怨而誅不直，微用兵而寄於義，則亡天下可跼足而須也。明於諸侯之故，察於地形之理者，不約親，不相質而固，不趨而疾，眾事而不反，交割而不相憎，俱彊而加以親。何則？形同憂而兵趨利也。何以知其然也？昔者齊、燕戰於桓之曲，燕不勝，十萬之眾盡。胡人襲燕樓煩數縣，取其牛馬。夫胡之與齊非素親也，而用兵又非約質而謀燕也，然而甚於相趨者，何也？何則形同憂而兵趨利也。由此觀之，約於同形則利長，後起則諸侯可趨役也。

 

It is said, 'When a thoroughbred[38] grows old, any old nag could outrun it; if Meng Ben[39] were already tired then a little girl could beat him." Neither the old nag nor little girl have tougher sinews or stronger bones[40] than the thoroughbred or Meng Ben, so why is this?  Because they have the resources available to the second-mover. Now the states of All-Under-Heaven lean on one another and so they have not yet wiped one another out. If you[41] hold your men in reserve and move second, entrusting your grudges to others and executing anyone shows dishonesty, minimising your use of troops and using the pretext of morality when you do deploy them, then your hegemony[42] over All-Under-Heaven is certain even if you do not move a single step. If you understand the reasoning of the feudal lords, examine the layout of their territories, make no close alliances, reinforce your position without exchanging hostages, and advance without rushing, then in all your joint enterprises you will encounter no betrayals and your exchanges of land will nourish no feuds, but rather they will help you grow stronger and augment your allies. How is this? Suffering the same conditions, you will share the profits whenever you dispatch troops. How do I know this to be so? In the past, Yan and Qi[43] fought at Hengzhiqu[44]. If Yan did not prevail, though it expended a hundred thousand men, it was because the partisans of the Hu[45] were also raiding multiple Loufan[46] counties in Yan, taking cattle and horses. The Hu had no formal relationship with Qi, and yet in their deployment of their troops they schemed together against Yan without having signed any treaties or exchanged any hostages. Nevertheless, when the circumstances arose, they hurried to one another's aid. Why was this? Because[47] they were suffering under the same conditions, with the same profits to be gained from dispatching their troops. From this perspective, treaties born of shared circumstances are the most profitable, and by moving second, you can ensure that the feudal lords will hurry to your service.

​

「故明主察相，誠欲以伯王也為志，則戰攻非所先。戰者，國之殘也，而都縣之費也。殘費已先，而能從諸侯者寡矣。彼戰者之為殘也，士聞戰則輸私財而富軍巿，輸飲食而待死士，令折轅而炊之，殺牛而觴士，則是路君之道也。中人禱祝，君翳釀，通都小縣置社，有巿之邑莫不止事而奉王，則此虛中之計也。夫戰之明日，尸死扶傷，雖若有功也，軍出費，中哭泣，則傷主心矣。死者破家而葬，夷傷者空財而共藥，完者內酺而華樂，故其費與死傷者鈞。故民之所費也，十年之田而不償也。軍之所出，矛戟折，鐶弦絕，傷弩，破車，罷馬，亡矢之大半。甲兵之具，官之所私出也，士大夫之所匿，廝養士之所竊，十年之田而不償也。天下有此再費者，而能從諸侯寡矣。攻城之費，百姓理襜蔽，舉衝櫓，家雜總，身窟穴，中罷於刀金。而士困於土功，將不釋甲，期數而能拔城者為亟耳。上倦於教，士斷於兵，故三下城而能勝敵者寡矣。故曰：彼戰攻者，非所先也。何以知其然也？昔智伯瑤攻范、中行氏，殺其君，滅其國，又西圍晉陽，吞兼二國，而憂一主，此用兵之盛也。然而智伯卒身死國亡，為天下笑者，何謂也？兵先戰攻，而滅二子患也。日者，中山悉起而迎燕、趙，南戰於長子，敗趙氏；北戰於中山，克燕軍，殺其將。夫中山千乘之國也，而敵萬乘之國二，再戰北勝，此用兵之上節也。然而國遂亡，君臣於齊者，何也？不嗇於戰攻之患也。由此觀之，則戰攻之敗，可見於前事。

 

Thus, when an enlightened sovereign and a watchful chancellor form a sincere will to attain hegemony[48], armed attack should not be their first recourse. War is an affliction for the state, and an expense for the capital and the regions. Those who begin by subjecting themselves to afflictions and expenses but are still able to make followers of the feudal lords are few. This is why war is an affliction: when officers hear that a war is coming, they transport their private wealth to supply the army markets[49], bringing food and drink to serve those destined to die. The carriages[50] are broken up to cook the food and the oxen killed to provide a feast for the officers. Such is the conduct of an army on the march[51]. Prayers go up among the people and their lord makes offerings; from the capital to the smallest counties altars are set up, and there is no city or district in which business does not cease, the better to serve the King. This is a strategy that will hollow out the state. On the day that follows the battle, the dead are laid out[52] and the wounded propped up. The army that was sent out returns depleted, and there is weeping in the land, making the sovereign's heart ache. Funerals for the dead ruin their families, while those with open wounds exhaust their savings buying medicines. Those still uninjured return and drink in wasteful celebrations, so their costs are equal to those of the dead and wounded. Thus the people's expenses are such that ten years in the fields cannot compensate them. When the army is deployed, the spears and halberds snapped, the ring swords and bowstrings broken[53], the crossbows damaged, the chariots crashed, the horses worn out and the losses and thefts account for half of the total equipment. Of the arms and armour prepared from the private resources of the ruling house[54], the quantity hidden by the high-ranking officers and stolen by their servants and underlings is such that ten years in the fields cannot compensate for it. Those in All-Under-Heaven who thus repeatedly deplete their resources but are able to make followers of the feudal lords are few. When a city is attacked, the cost is borne by the hundred clans, who must repair the defences and raise assault towers, entire families toiling together, taking on the work of sappers though they have ceased receiving any pay[55]. The officers are trapped within their earthworks and their generals never take off their armour. Anyone who can seize a city in just a few months is quick indeed; leaders run out of commands and subordinates abandon their manoeuvres. Thus, those who can bring down three cities and still defeat the enemy are few. Therefore I say, war should never be the first option. How do I know this to be so? In the past, Zhi Boyao[56] attacked the Houses of Fan[57] and Zhonghang[58], killing their lords and extinguishing their states. He then moved west and encircled Jinyang[59], uniting two states[60] to bring grief to one lord[61]. Thus, his military capacities flourished, but even so, Bo Zhi ended up dead with his state exterminated, and All-Under-Heaven laughed. Why would you say this happened? Because his first recourse was to deploy his troops for an armed attack, he suffered misfortune though he had already exterminated two princes[62]. In the past[63], Zhongshan mobilised all its troops and went out to meet Yan and Zhao. In the South they fought at Zhangzi[64] and defeated the House of Zhao; in the North they fought in Zhongshan and overcame Yan's army, killing its general. Zhongshan was a state of a thousand chariots, but was the equal of[65] two states of ten thousand, winning battle after battle in the North[66]. This showed its superior ability in deploying troops. Even so, the state was destined for extinction, with its Lord[67] becoming a servant of Qi. Why was this? Because it was not parsimonious in its recourse to the scourge of war. From this point of view, its defeat in battle can be seen to be the result of its having precipitated affairs[68]. 

​

「今世之所謂善用兵者，終戰比勝，而守不可拔，天下稱為善，一國得而保之，則非國之利也。臣聞戰大勝者，其士多死而兵益弱；守而不可拔者，其百姓罷而城郭露。夫士死於外，民殘於內，而城郭露於境，則非王之樂也。今夫鵠的非咎罪於人也，便弓引弩而射之，中者則善，不中則愧，少長貴賤，則同心於貫之者，何也？惡其示人以難也。今窮戰比勝，而守必不拔，則是非徒示人以難也，又且害人者也，然則天下仇之必矣。夫罷士露國，而多與天下為仇，則明君不居也；素用強兵而弱之，則察相不事。彼明君察相者，則五兵不動而諸侯從，辭讓而重賂至矣。故明君之攻戰也，甲兵不出於軍而敵國勝，衝櫓不施而邊城降，士民不知而王業至矣。彼明君之從事也，用財少，曠日遠而為利長者。故曰：兵後起則諸侯可趨役也。

 

Nowadays, those who are called skilled in the use of troops are those who emerge victorious from a fight to the death or who defend their positions at all costs[69]. All-Under-Heaven calls skilful those who can obtain and defend a state, which brings no benefits to the states themselves[70]. Your servant has heard that the greater the battle you win, the more of your officers will die and the weaker your troops will grow. If you maintain your positions at all costs, the hundred clans will grow exhausted and the outlying districts will be left exposed. Your officers will die abroad while your people are afflicted at home and your border regions are left unprotected. This will bring Your Majesty no joy. Now an archery target has committed no offense against anyone[71], but it is easy to pick up a bow or a crossbow and shoot at it. Those who hit the target are contented[72] while those who fail are embarrassed, no matter whether they are young or old, noble or humble, all feel the same way about it. Why is this? Because all hate to have others see them struggling. Nowadays states deplete themselves seeking victory in battle and defend their positions at all costs. Not only does this allow others to see that they are struggling, but by doing so they injure others, and - this being so - they will certainly attract the enmity of All-Under-Heaven. Your officers will grow exhausted and your state will be left exposed, while your enemies multiply; therefore an enlightened sovereign does not take up such a position. Frequent use of strong troops will weaken them, therefore a perceptive chancellor will not undertake such an affair. An enlightened sovereign and a perceptive chancellor will not move five troops[73] but the feudal lords will follow; they use courteous words and impressive gifts arrive. Thus, when an enlightened sovereign goes to war, no troops are formed up but the enemy is defeated. No siege towers are built, but border walls fall. Without officials or citizens realising, the king's work is completed. When an enlightened sovereign pursues his affairs, he uses few resources, but as the days stretch out his profits increase[74]. Therefore I say: if your troops move second, then you will soon be able to make servants of the feudal lords.

​

「臣之所聞，攻戰之道非師者，雖有百萬之軍，比之堂上；雖有闔閭、吳起之將，禽之戶內；千丈之城，拔之尊俎之間；百尺之衝，折之衽席之上。故鍾鼓竽瑟之音不絕，地可廣而欲可成；和樂倡優侏儒之笑不之，諸侯可同日而致也。故名配天地不為尊，利制海內不為厚。故夫善為王業者，在勞天下而自佚，亂天下而自安，諸侯無成謀，則其國無宿憂也。何以知其然？佚治在我，勞亂在天下，則王之道也。銳兵來則拒之，患至則趨之，使諸侯無成謀，則其國無宿憂矣。何以知其然矣？昔者魏王擁土千里，帶甲三十六萬，其強而拔邯鄲，西圍定陽，又從十二諸侯朝天子，以西謀秦。秦王恐之，寢不安席，食不甘味，令於境內，盡堞中為戰具，竟為守備，為死士置將，以待魏氏。衛鞅謀於秦王曰：『夫魏氏其功大，而令行於天下，有十二諸侯而朝天子，其與必眾。故以一秦而敵大魏，恐不如。王何不使臣見魏王，則臣請必北魏矣。』秦王許諾。衛鞅見魏王曰：『大王之功大矣，令行於天下矣。今大王之所從十二諸侯，非宋、衛也，則鄒、魯、陳、蔡，此固大王之所以鞭箠使也，不足以王天下。大王不若北取燕，東伐齊，則趙必從矣；西取秦，南伐楚，則韓必從矣。大王有伐齊、楚心，而從天下之志，則王業見矣。大王不如先行王服，然後圖齊、楚。』魏王說於衛鞅之言也，故身廣公宮，制丹衣柱，建九斿，從七星之旟。此天子之位也，而魏王處之。於是齊、楚怒，諸侯奔齊，齊人伐魏，殺其太子，覆其十萬之軍。魏王大恐，跣行按兵於國，而東次於齊，然後天下乃舍之。當是時，秦王垂拱受西河之外，而不以德魏王。故曰衛鞅之始與秦王計也，謀約不下席，言於尊俎之間，謀成於堂上，而魏將以禽於齊矣；衝櫓未施，而西河之外入於秦矣。此臣之所謂比之堂上，禽將戶內，拔城於尊俎之間，折衝席上者也。」

 

What your servant has heard is that the way to win in war is not by leading out troops. Even a million-man army can be overcome from within the palace. Even generals like Helü[75] or Wu Qi[76] may be captured without going out of doors. A city of a thousand zhang can be seized during an official banquet. Siege works of a hundred square chi can be broken down from your mat[77]. Thus, before the last notes of the glasses, drums, flutes and zithers have died away, your land may have been expanded and your wishes fulfilled; before the laughter of the singers, dancers, the actors and dwarfs has ceased[78], the feudal lords may that same day arrive to pay homage to you. To call you the equal of heaven and earth would not then be sufficiently respectful, and control over all within the seas would not be excessive compensation. Therefore, one skilled in the work of a king succeeds by allowing All-Under-Heaven to work while he indulges himself, and causes All-Under-Heaven to sink into chaos while remaining calm himself. The feudal lords cannot bring off their schemes against him, so no misery can linger even a night within his state. How do I know this to be so[79]? To create easeful order at home[80] and chaotic striving within All-Under-Heaven, such is the path of a true king. When elite troops arrive he dismisses them with a wave of his hand[81], and when trouble arrives he hurries it away[82]. Because he can ensures the failure of the feudal lords' schemes, no misery can linger even a night within his state. How do I know this to be so[83]? In the past, the King of Wei's[84] territories encompassed thousands of li of land, guarded by three hundred and sixty thousand troops. Relying on[85] his strength he captured Handan[86] and turned west to encircle Dingyang[87], bringing twelve feudal lords to the court of the Son of Heaven[88] to plot against Qin in the West. The King of Qin[89] was afraid; he could not sleep peacefully in his bed and his food no longer tasted sweet. He dispatched orders within his borders to prepare all fortresses for war, to be ready to defend the frontiers[90], and to appoint as generals officers who were willing to face death, awaiting the arrival of the Wei forces. Wey Yang[91] presented a strategy to the King of Qin, saying, 'The House of Wei has achieved great things, and its orders are followed throughout All-Under-Heaven. Twelve of the feudal lords have followed them to pay homage in the court of the Son of Heaven, and there will certainly be more. Therefore, if Qin attempts to face down mighty Wei alone, I am afraid we will not be adequate to the task. Why not send your servant to seek an audience with the King of Wei? I beg permission to ensure Wei's collapse.' The King of Qin assented. Wey Yang went to see the King of Wei, and said,  'Your Majesty has achieved great things, and your orders are followed throughout All-Under-Heaven. Now of the twelve feudal lords who are following you, Song and Wey can be exempted[92], but Zou, Lu, Chen and Cai will definitely allow themselves to be whipped into line, but that is not enough to make you a king in All-Under-Heaven. There would be no better approach than to take Yan in the North and attack Qi in the East, then Zhao will certainly follow you. If you take Qin in the West and attack Chu in the South, then Han will definitely follow you. If you make up your mind to attack Qi or Chu, then you will create a common purpose within All-Under-Heaven and the completion of your hegemonic task is within sight. The best thing for Your Majesty would be to first proceed to put on the royal regalia, and - this being done - make plans against Qi and Chu.' The King of Wei was delighted by Wey Yang's speech, and expanded his palace, commissioning cinnabar-dyed royal robes and lifting the Dragon Flag and the Seven-Star Banner[93]. Thus the King of Wei assumed the place of the Son of Heaven. In such circumstances, Qi and Chu were full of indignation. The feudal lords hurried to Qi's side and then Qi's partisans attacked Wei, killing Wei's Crown Prince[94] and pushing back an army a hundred thousand strong. The King of Wei was terrified, and went bare-footed to demobilise his troops and bring them home, before going east to submit to Qi. It was only after this that All-Under-Heaven would let him go. The opportunity having occurred, the King of Qin was able - with his hands folded in his sleeves - to acquire[95] territories West of the Yellow River, and avoid paying tribute to Wei[96]. Thus[97], when Wey Yang first presented his plan to the King of Qin, the strategy was agreed upon before they got up from their mats, discussed further as they ate, and completed within the palace... And thus Wei's General[98] was entrapped by Qi. No siege engines were deployed, and yet the lands West of the Yellow River were incorporated[99] into Qin's own territories. This is what your servant means by overcoming from within the palace, capturing a general without going outdoors, seizing a city during a banquet, and breaking a siege from your mat."
