When the three captured generals returned to Qin, Duke Mu put on plain mourning clothes and went outside the city to meet them. They brought no spoils, only the consequences of a disastrous defeat. Their expedition had been ambushed at Xiao, and its commanders taken prisoner by Jin. Now Jin had sent all three men home. The duke could easily have laid the blame on them. Instead, he wept and said that his own refusal to listen had brought them disgrace.

That is one of the scenes I remember most strongly when writing about Duke Mu. Yet it would make the story too easy to describe him simply as a wise ruler willing to admit his mistakes. Before the expedition, others had explained the danger clearly. He had heard them and proceeded anyway. The three generals returned because someone in another country pleaded for their release. Qin's soldiers who did not come home had no such opportunity.

Let me begin with a much earlier episode. Duke Mu wanted to obtain the services of Baili Xi. In the end, he paid five black ramskins. Later generations remembered the astonishingly small price, sometimes forgetting why Baili Xi had reached a situation in which someone could ask for him in exchange for skins.

Baili Xi had served the state of Yu. When Jin conquered it, he became a captive and was subsequently sent to Qin among the servants accompanying a Jin bride. He escaped from Qin, reached Wan, and was seized by people on the border of Chu. Office had not protected him through the fall of his country, captivity, service as part of a marriage retinue, and capture again.

Hearing that Baili Xi was a capable man, Duke Mu initially wanted to offer a large ransom. Then he reconsidered. If Chu discovered how valuable this captive was, would it still release him? His envoy therefore made a different request: Qin's runaway bridal servant was being held there, and Qin would redeem him for five skins. Chu agreed. Qin gained a man; the story gained a memorable title, the Minister of the Five Ramskins.

When Baili Xi was brought before him, Duke Mu loosened his bonds and asked about government. Baili Xi replied that an official whose state had perished was hardly worth consulting. The duke did not continue blaming the defeated man. The ruler of Yu had failed to employ him, he said; that was why Yu had fallen, and it was not Baili Xi's fault. They talked for three days, after which the duke entrusted him with affairs of state.

No complete record survives from which we could reconstruct those three days of questions and answers. What remains is what followed: a man reclaimed as a runaway servant was asked to help direct a state. Having recognized his abilities, Mu did not allow his former status as an official of a defeated country to bar the way. Coming to Qin changed the position he could occupy.

More interestingly, Baili Xi did not intend to close the door to other able men behind him. His friend Jian Shu, he said, was better than he was. In poverty, Jian Shu had fed him. More than once, Jian Shu had advised him against serving a particular ruler, and following that advice had saved him. Finally, tempted by office, he had disregarded the warning and stayed in Yu, where he was captured. Duke Mu sent rich gifts and invited Jian Shu to Qin as well.

In the dealings between Qin and Jin that followed, marriage, grain, land, and armies were repeatedly entangled. The Jin prince Yiwu asked Qin to help him return home. Once installed, however, he failed to deliver the territory west of the Yellow River that he had promised. Pi Bao, a Jin exile in Qin, urged Duke Mu to attack. The duke declined to act immediately. A ruler still capable of executing powerful ministers, he reasoned, retained control over his state.

Then famine struck Jin, which requested grain from Qin. Pi Bao called this a heaven-sent opportunity and opposed relief. Baili Xi distinguished the ruler from his subjects: the ruler had offended Qin, but what wrong had the people done? Qin supplied grain, with carts and boats carrying it between Yong and Jiang. Food crossed the frontier and also crossed the divide left by a broken agreement.

When Qin suffered a shortage in turn, Jin refused assistance. Relief had not settled the old grievances. The two states eventually fought at Han. Duke Mu pursued Duke Hui of Jin, only to find himself surrounded and wounded. The men who rescued him were people who might previously have died at the hands of Qin's own officers.

More than three hundred people had obtained one of the duke's fine horses after it strayed near Mount Qi. They slaughtered and ate it. Officers arrested them and intended to apply the law. Duke Mu said that a gentleman should not harm people for the sake of livestock. Because of a contemporary belief that eating horseflesh without wine was harmful, he also supplied them with wine and pardoned them. That belief was not medical knowledge, but the pardon became essential to the rest of the story.

On learning of the war, these men volunteered for service. When Duke Mu was surrounded, they fought their way into the Jin army and rescued him. Duke Hui instead became a prisoner. Mu initially contemplated sacrificing him to Heaven. The Zhou king intervened on behalf of a ruler of his own clan, and Mu's wife, Hui's sister, put on mourning clothes and pleaded barefoot for her brother. Hui was eventually allowed home, surrendering territory and sending his son to Qin as a hostage.

At this point, one might suppose that the recipients of such help would finally remember it. Yet the hostage prince later fled back to Jin. Qin then supported the long-exiled Chong'er and escorted him home to become Duke Wen. Mu had helped more than one ruler of Jin, but that could not guarantee Jin's permanent obedience. The interests of states did not disappear at weddings or farewells.

The difference emerged again when Qin and Jin jointly besieged Zheng. Zhu Zhiwu, a man of Zheng, was lowered from the city wall at night and approached Duke Mu. He offered no appeal to affection. He explained the practical gains and losses. Qin was far from Zheng. Its destruction would chiefly enlarge nearby Jin. If Zheng survived, it could provision Qin's travelling envoys. Jin's earlier broken promises were recalled as well.

Duke Mu made peace with Zheng, left Qi Zi and other men to serve there, and took his army home. Some in Jin wanted to strike the withdrawing Qin force, but Duke Wen refused. The two states had not yet broken entirely. Later, however, the Qin men left in Zheng would turn a position created through cooperation into an opportunity to tempt Qin into attacking its ally.

After Duke Wen died, Qi Zi sent word from Zheng that he controlled the northern gate. If a Qin army arrived secretly, the city could be taken. The gate seemed already open. All Mu apparently needed to do was send an army through it. Yet the journey from Qin to Zheng was not a corridor within his palace. Other people's lands lay between them, together with decisions those people remained free to change.

Baili Xi and Jian Shu opposed the distant raid. An army passing through several states could not remain hidden, they said. Men willing to disclose information to Qin might also disclose it elsewhere. Mu ignored them and sent Mengming Shi, Xiqi Shu, and Baiyi Bing. The commanders included sons of the two elderly advisers. A warning against war thus also became a father's farewell to a son.

In my Annals of Qin, both old men weep as the troops depart, and Mu accuses them of weakening military resolve. They explain that they are old and fear dying before their sons return. Privately, they tell the sons something more frightening: if disaster comes, it will probably come in the difficult country of Xiao. Another ancient text centres the warning on Jian Shu alone. These versions should not be forced into one conversation with every participant present. Their central danger is nevertheless the same: the distant raid has left no secure road home.

Near Hua, the Qin army encountered Xian Gao, a merchant of Zheng who was driving cattle westward. Suddenly faced with an army advancing towards his country, he offered cattle as provisions and acted as though he had been sent by Zheng's ruler to receive it. At the same time, he sent an urgent warning home. A man travelling on business had interrupted the secrecy on which the expedition depended.

Mengming Shi and the others concluded that surprise was no longer possible. Their army, after its long march, was also poorly placed to begin an unprepared siege. They attacked and destroyed Hua instead and started back. They had failed to achieve their original objective, while creating another conflict on the road home.

In the other part of the Zuo Tradition's account, Zheng did not simply wait. After the warning arrived, its people inspected the quarters of the Qin men and found their baggage packed, weapons sharpened, and horses fed. Zheng sent someone to suggest politely that they leave, as if concerned about the inconvenience of their lengthy stay. The gatekeepers fled. Once the merchant's warning exposed the secret arrangement, the men inside no longer had the opportunity to open the city.

Jin's new ruler, Duke Xiang, was still mourning his father. Its ministers argued about attacking the Qin army that had crossed Jin's territory and destroyed Hua. Some recalled Qin's past assistance; others insisted that the opportunity must not be lost. Jin, with Jiang Rong allies, defeated Qin at Xiao and captured the three commanders. A father had helped Duke Wen gain his throne; now the next generation was fighting under Duke Wen's son. War turned the old relationship back upon itself.

Duke Wen's funeral and the battle occurred close together. Xiang fought in mourning garments dyed black. This was not a country without effective leadership, whatever the expedition may have expected. The old ruler was dead, but the new ruler and his ministers could still make decisions, and an army could still act. Mu had treated the death as an opening while underestimating the other state's ability to assemble its strength.

The person who secured their release was Duke Wen's widow, Wen Ying. She came from Qin and asked Duke Xiang to return the defeated commanders so that Qin's ruler could punish them. After Jin agreed, an angry objection was raised, but the pursuit came too late. The prisoners crossed the river and returned home. That was how the meeting in plain mourning clothes, with which I began, became possible.

Mu did not remove Mengming Shi from command. He said that one failure should not obscure a man's strengths. Yet sparing a general did not produce immediate victory. Qin lost again at Pengya. Later, Mengming Shi crossed the river, burned his boats, and captured Jin towns while the Jin forces remained behind their walls. Mu also went to Xiao to bury the dead, mourned for three days, and returned to his own failure to heed the elderly advisers.

Ending there would produce a satisfying account of a ruler learning how to employ men through his mistakes. But another course followed in Mu's later years cannot be omitted. The king of the Rong sent You Yu to Qin. His ancestors came from Jin, and he knew the language of the central states. Mu showed him buildings and wealth. You Yu asked how much hardship the people must have endured if human labour had produced them.

Mu also asked about something that puzzled him. The central states possessed poetry, books, ritual, music, and laws, yet repeatedly fell into disorder. How did the Rong govern without them? You Yu did not offer the praise of the central states his host might have expected. He described rulers and subjects living securely through mutual trust; merely creating laws while using power for competition could generate disorder instead. This envoy had political ideas of his own, rather than arriving simply to learn how Qin had become wealthy and strong.

Mu did not end the conversation because the answer was unwelcome. He questioned You Yu about the Rong lands and their government, while worrying about such a capable man serving a neighbour. A Qin official proposed sending female performers to the Rong king and delaying You Yu's return, creating estrangement between ruler and minister. You Yu returned, offered remonstrance that was ignored, and eventually came to Qin. Recruiting talent and sowing division were not neatly separate activities in this affair.

With You Yu's assistance, Qin expanded westward and received recognition from the Zhou king. Such achievements made Mu a powerful ruler whom later generations remembered. Yet I placed another event near the end of his account. When he died, one hundred and seventy-seven people were buried with him, including three worthy men, Yanxi, Zhonghang, and Zhenhu. The people of Qin lamented them in the song Yellow Birds.

A ruler who had pardoned men for eating his horse and wept over defeated generals was followed into his grave by so many people. He had once loosened Baili Xi's bonds. Other lives ended at his funeral. I cannot devise a calculation in which one act cancels the other.

I would therefore have readers remember the three generals who came home and the three worthy men who did not leave the funeral alive. Mu's life contains both the strength gained through people and the sorrow of losing them. The moment when he stood outside his city and admitted fault deserves to be recorded. Having recorded it, we must still read on.
