The lords had arrived. Their troops had arrived. King Wu did not go farther.

At Mengjin, leaders who had come from different lands urged him to attack Shang. They had not gathered simply to listen to a king postpone his decision. King Wen was dead, Zhou had a new leader, and the king of Shang still occupied his throne in the east. Between them lay not only a river but many decisions that had yet to be made.

The answer I preserved was brief. King Wu said the time had not come. The army went home.

Viewed backward from the victory at Muye, this withdrawal can look like a short pause on a road that led inevitably to success. Taken by itself, it shows a man who did not yet possess the realm. He could accept the lords' urging and turn their gathering into war. Or he could send them back and bear the consequences of an assembly that had fought no battle. He chose the latter. We cannot supply his calculations of the odds, or an unrecorded conversation in which one adviser persuaded another.

His personal name was Fa. The enterprise he inherited was far from empty. King Wen had campaigned, moved his center, and attracted lords, but had not destroyed Shang. Lü Shang was Fa's teacher, the Duke of Zhou assisted him, and the dukes of Shao and Bi stood beside him. His father's officers and allies now had to act under the son's command. This was not a finished crown transferred from one head to another. Strength accumulated over many years had to be made capable of moving together.

On this eastern expedition the army carried a wooden ancestral tablet of King Wen. Fa still called himself the crown prince, declaring that he acted in continuation of his father's enterprise, not on his own authority. A dead man, represented by a tablet, occupied the center of the army. The new ruler's actions were joined to the old ruler's reputation. Yet marching, crossing the river, rewarding, punishing, and withdrawing remained decisions for living people.

The Mengjin tradition also contains a white fish entering the royal boat and fire turning into a red bird. I retained these stories, but fish and birds cannot decide for an army. They belong to ancient explanations of Heaven's mandate, not to replayable battlefield footage. What kept this assembly from becoming a decisive battle was King Wu's order to return.

The news that followed was worse. Bigan had been killed and Jizi imprisoned. Shang's senior music masters Ci and Qiang fled to Zhou with their instruments. Not merely two men had left: part of Shang's royal establishment had come with them. Instruments associated with the dynasty's ritual order traveled away in the hands of their custodians. A fracture inside the old court became visible to Zhou in this concrete form.

When King Wu went east again, he had decided to attack. The transmitted account gives three hundred chariots, three thousand elite warriors, and forty-five thousand armored soldiers; it gives a larger chariot total after the allied forces assembled. These numbers suggest an army that was more than the king's personal following. They are not a modern muster roll. We possess neither the organization of every contingent nor individual registrations, and cannot turn them into an exact map of troop strength.

Another tradition makes the departure unpromising: the divination was unfavorable, wind and rain arrived violently, the nobles were afraid, and Taigong alone insisted that the king proceed. It contrasts with the earlier withdrawal. First King Wu had declined to fight despite the lords' urging; later he did not stop because of an unfavorable sign. These are different choices preserved in two ancient narratives. They do not authorize an invented interior monologue in which the king suddenly understood Heaven amid a storm.

At last the army reached Muye.

On a jiazi day, before full daylight, King Wu addressed the lords and soldiers. He held a yellow battle-axe in his left hand and a white standard in his right. The force included not only Zhou people but groups named Yong, Shu, Qiang, and others. Leaders, officers, commanders of thousands and commanders of hundreds also had their places in the address. This was an alliance that had to be bound together by common orders, not a realm already standing neatly behind its new king.

The oath announced the Shang ruler's offenses and then turned to movements in battle. Advance a few paces and halt to restore alignment; make a limited sequence of attacks and bring the formation together again. Once weapons were raised, individuals were not simply to compete in courage. The force would move forward and then realign. If its order dissolved, numbers would cease to mean strength. These commands leave a more concrete outline of warfare than a declaration of invincibility.

One instruction mattered especially: do not obstruct men fleeing from Shang's forces, but allow them to serve the western cause. An enemy army was not composed only of people to be killed or driven away. Some might abandon their old lord and enter a new order. King Wu sought to break not just the opposing formation but Shang's hold on people.

The oath blamed Shang's ruler for listening to a woman and condemned his use of fugitives rather than royal relatives. This was the conqueror's language of justification. It does not establish that a woman caused Shang's fall, or that every fugitive embodied wickedness. The actual conflicts of late Shang were more complicated than a wartime indictment could accommodate. We can explain the reasons King Wu offered without making those reasons the whole history of his opponent.

When fighting began, Taigong and a body of warriors challenged the enemy, and the main force advanced rapidly. In the transmitted account Shang's army was enormous but collapsed quickly. Some reversed their weapons and opened a way for Zhou. Later tellings often make this reversal the common decision of all Shang people. No complete record survives to show how many changed sides, how many fled, or how many still resisted. The figure of seven hundred thousand is subject to the same evidentiary limits.

The Shang ruler retreated, ascended the Deer Terrace, clothed himself in a garment adorned with precious jade, and burned himself to death. A dynasty's ending is compressed into striking actions: the army scattered, the ruler left the battlefield, and he died on his own terrace. Yet Shang people did not disappear with their king. Their land, sacrifices, kin groups, and former officers did not all turn to ash.

King Wu entered Shang's domain. People waiting outside the city bowed to him, and he bowed in return. Zhou's narrative makes this resemble an initial recognition between a new ruler and the old population. What follows is brutal. King Wu shot at the dead ruler, cut off his head, and displayed it on a standard. He treated two royal favorites who had already killed themselves in a similar way. Removing these actions to make the victor a wholly benevolent sage would change the story. Conquest and intimidation belonged to this victory too.

Ritual proclamation came next. Roads were cleared; the altar and palace were put in order. The dukes of Zhou and Bi held axes, close officers guarded the king with swords, Taigong led the sacrificial animal, and the scribe pronounced the Shang ruler's offenses. King Wu bowed, declaring that he received a new great mandate. Power just taken by force had to be proclaimed as power rightly received. Armed men beside the ritual also showed what sustained that proclamation.

But King Wu did not exclude the Shang ruler's son from the new arrangement.

Lufu, also known as Wugeng, remained to govern Shang's surviving population. The king's brothers Guan and Cai were appointed to assist him. The conquered territory was not yet settled, and sending in soldiers would not make every problem disappear. The former royal family still had a role; the new ruler's brothers exercised oversight. Zhou used existing connections while placing them under its supervision.

Orders followed one another. Release Jizi. Release prisoners among the population. Honor Shang Rong. Distribute the Deer Terrace's wealth. Open the granary at Juqiao and assist poor and vulnerable people. Attend to Bigan's tomb. These actions were more specific than an abstract promise of humane government. Imprisoned people had to be freed, concentrated wealth dispersed, and stored grain placed in the hands of those who needed it. The victor had to show that a change of ruler would affect ordinary lives.

The same conquest included displayed heads and opened granaries. It broke the Shang king's authority while preserving his descendants. A story of pure liberation would hide the axes; a story of plunder alone would lose the measures through which the new rule took hold. Their tension is no reason to erase either side.

King Wu also ordered officers to inspect the nine tripods and precious jade. Unlike grain, these were not simply useful goods: they were associated with dynastic ritual and authority. Their custody and ritual use mattered to the distribution of power after conquest. Opening granaries, safeguarding precious vessels, proclaiming the mandate, and granting rewards turn one victory into many distinct tasks. An army could take a city, but it could not substitute for people continuing their lives at altars, in fields, and in the newly established domains.

King Wu returned west and granted domains to officers, advisers, and relatives. Taigong received Qi, the Duke of Zhou Lu, and the Duke of Shao Yan; Guan and Cai received territories too. Men who had moved together in the army began to establish authority in separate places. Victory became a network of kinship, alliances, and domains, intended to reach places the king could not constantly visit himself.

The grants also included descendants of ancient rulers. The transmitted narrative incorporates them into Zhou's founding arrangements, as if the new king inherited a past extending beyond Shang as well as Shang's land. This is the order depicted by ancient history, not a contemporary register verifying every genealogy and boundary. It does not tell us how each recipient traveled or how local people received him; no journeys or welcoming scenes are invented here.

Yet after returning to Zhou, King Wu could not sleep.

Ancient tradition has the Duke of Zhou come to ask why. The king's answer turns on a problem: the newly acquired rule was not secure, so how could he have leisure to sleep? He discussed the country of the Luo and Yi rivers and the eastern seat of power. This is not a feast at which the victor has already arranged everything. It is a moment when a new dynasty must still confront distance. Shang's king had fallen. How to hold Shang's territory and connect east with west had not been settled on that jiazi morning.

I also preserved the tradition of Boyi and Shuqi stopping the king's horse to remonstrate. They questioned an attack undertaken before a father's burial and a subject's assault on his ruler. The attendants wanted to use weapons; Taigong called the brothers righteous and had them led away. Later they refused Zhou grain, withdrew, and starved. This cannot be fitted precisely into every army timetable. Nor is it contemporary testimony deposited by the two men. It nevertheless preserves a judgment that refused to change with victory.

Set beside King Wu's story, that voice keeps a founding from becoming unanimous praise. He could win and receive the lords' allegiance while others rejected his explanation. I did not let those two men vanish from history because he established Zhou.

King Wu eventually fell ill. The nobles were afraid, and the Duke of Zhou prayed to substitute himself for his brother. The king improved, then later died, and the young King Cheng succeeded him. Ancient chronology still presents difficulties concerning his reign and the intervals between these events. Their transmitted sequence cannot all be converted into undisputed absolute years. The subsequent rebellion involving Wugeng and the dukes of Guan and Cai shows that the conquest settlement did not guarantee stability. That belongs to the next story, about the Duke of Zhou, and remains an open problem at the end of this one.

Looking back to Mengjin, I prefer to remember the army that assembled and then obeyed an order to return. King Wu did not decide the realm at his first gathering. At Muye, he did not settle it with a single victory either. One jiazi day could decide a ruler's life and death. Establishing a new order required many things that had not ended that day to continue unfolding.

Its inscription supports the central event of King Wu's campaign on a jiazi morning, not every transmitted speech, army total, or subsequent detail. The museum uses the traditional location south of modern Qi County for Muye. An accessible search listing for the Qihe Culture Research Center at Hebi Polytechnic, Muye Place-Name Study, https://qhwh.hbzy.edu.cn/info/1085/1849.htm , was used only as a clue to disputed geography; its full text could not be retrieved and is not represented as read or as adjudicating the battlefield. No Muye coordinate is forced into the map. Chapter 4 gives a jiazi day in the second month; chapter 32 gives one in the first. These are not harmonized or converted to a Gregorian day. A cyclical day alone does not establish an absolute conquest year; this story uses approximately the eleventh century BCE as background. Mengjin's crossing, Muye's battlefield, the Deer Terrace, Juqiao, the eastern grants, and settlement along the Luo and Yi remain without forced precise pins. The white fish and red bird are omen traditions. The remonstrance, sleeplessness, and prayer of substitution are later transmitted narratives, not contemporary verbatim records.
