The Great Reversal at Cheongsan
From the watchtower that commanded a full view of the battle’s flow at Cheongsan, Xiang Tai and I could only watch in awe. The first shift came on the left wing. That sector of the Alliance army was locked in combat with the Qin right wing—the fiercest clash of the entire field, for it faced Biao Gong’s main force of heavy cavalry. The plan was to shatter the left wing and then hammer the Alliance center from three directions at once: front, flank, and rear. Even I, no student of tactics, recognized the classic hammer-and-anvil strategy.
The Alliance troops stationed on the left were from Chu and Yan. Chu’s powerful infantry held the forward line while Yan’s abundant cavalry blocked the Qin horsemen trying to sweep around the side. Xiang Yan, Ji Xin, and Bang Nan—two of the Alliance’s three greatest commanders—were committed here, so the defense was rock-solid. The two states were far apart and had never fought together before; I had worried their coordination would be clumsy. Yet because they openly acknowledged their differences, they divided the battlefield cleanly between them, and the result was surprisingly harmonious.
Still, numbers told in the end. The Qin assault proved too heavy. The first to buckle was Yan. Zhao’s armored cavalry might be the finest under heaven, but Yan itself was renowned for its horsemen. Qin’s cavalry, however, had expanded northward for generations, trading with the nomads; they were every bit as skilled. Worse, their attacks were fueled by numerical superiority and a raw aggression that made Yan’s own ferocity seem tame. The Yan riders began to give ground, then pivoted to their true specialty.
If they could not win on horseback, they would win with horse-archery. Executing dazzling turns, the elite of the elite—the Baesa Unit—led a deadly dance of strike and withdraw. The Qin army gave chase with murderous intent. As long as those skilled Yan riders remained capable of mounted archery, any attempt to strike the flank would be suicidal. Eliminating them had become the Qin priority.
And that was a fatal mistake.
“Those are… Zhao’s armored cavalry…!”
“They kept them in the rear on purpose—right from the beginning they were aiming for this moment…”
Chu and Yan on the left wing were our homelands, Xiang Tai’s and mine. We had been watching with clenched hearts; when the situation reversed in a single heartbeat the words simply burst from us.
This had been Lord Xinling’s true design all along. He himself was nothing more than bait. By showing himself at the front of the center army he drew every eye, deliberately pulling the Yan troops back to lure the Qin cavalry deep, then striking with the elite Hufu horsemen. Lure them with gain, let them underestimate you, and make them arrogant. Exactly as Sima Shang had predicted.
Then Sima Shang had read the entire picture from the very start?
That level of insight rivaled any active general. I turned to her, eyes full of admiration. Perhaps because the scene looked like Zhao troops riding to the rescue of Chu and Yan, Sima Shang’s shoulders were thrown back and her face glowed with triumph. The moment our eyes met she curled her lips into a cocky grin. No words were needed; that smile told me exactly what she wanted to say.
“How did you know?”
“What, it wasn’t hard. If they’d put the Hufu cavalry on the right wing they could have stopped Qin’s Zhang Dang army much more easily. Placing them in the rear instead? Clearly they had another use for them.”
I realized then that Lord Xinling’s earlier questions about our formation had been a test to see whether we had glimpsed this hidden design.
“Why didn’t you say anything at the time?”
“You hide something like this until the moment it begins. Lord Xinling never showed any sign he knew I’d caught on.”
So this was how geniuses saw the world. We had noticed nothing, yet the two of them had been carrying on an entire silent conversation. Even Xiang Tai could not follow the lightning-fast interplay between Lord Xinling and Sima Shang; he simply stared, stunned.
“Besides, everyone was so fixated on Lord Xinling that they missed the Hufu cavalry moving at all.”
The Hufu riders advanced with stealth and terrifying speed. After the first volley of arrows toppled rows of Qin horsemen, they drew swords and spurred forward. Their charge slammed into the exposed flank of the overextended Qin cavalry and sent the entire formation reeling. Yet the Qin riders, burning with rage at being attacked by an enemy that had dared to charge straight at them, immediately counterattacked. Had the Yan cavalry not wheeled about and smashed into them, the Qin might have regrouped and turned the fight into a savage melee.
But caught between two fires and hammered from both sides, even the Qin army had no answer.
Xiang Tai murmured the line from the Art of War that Sima Shang had once recited, as though tasting each word. The battle was now completely overturned. The Qin cavalry that had tried to envelop the Alliance left wing had fallen into the trap and been annihilated. That collapse spelled the destruction of the Qin right wing—the very “hammer” that was supposed to smash the Alliance center.
The combined Alliance cavalry that had devoured the Qin horsemen immediately launched their own encirclement. Biao Gong’s army, trusting too much in their cavalry, had focused solely on driving forward; their right flank was left thin. Strike where the enemy is unprepared. Following that principle, the Yan and Zhao horsemen tore into the Qin side without mercy.
“Mother is on the move!”
Xiang Yan never missed the opening. While the Qin ranks reeled in confusion from the surprise attack, she took the vanguard herself and began to push forward. Just as Yeo Hong-seong had once said—wondering aloud whether Xiang Yan might actually be stronger—her martial prowess was simply overwhelming. The disordered Qin lines crumbled helplessly before her.
A perfect exchange of roles. The snake that had tried to swallow the prey now found its own head being devoured. There was no path of escape.
In front stood Xiang Yan’s Chu army. On the right, the combined cavalry of Zhao and Yan. On the left, the Qin troops who had surged forward to capture Lord Xinling. No gap remained. The only possible retreat was to the rear, yet even that was hopeless. Having tasted victory, the Qin soldiers were surging forward with unstoppable momentum. The center had grown so dense in its obsession with catching Lord Xinling that the right wing’s space had shrunk to nothing. Any disorderly retreat now would only create a fatal bottleneck.
Yet the Alliance had its own weakness: the Zhao right wing. Originally fifty thousand strong, it had been reduced to forty thousand after half the Hufu cavalry were sent to the left wing. No matter how fiercely the remaining Hufu riders harassed the enemy, Qin’s Zhang Dang army had prepared from the outset. Shields locked, they had formed an iron phalanx that proved stubbornly resilient.
Still the Zhao army refused to break. Sima Shang laid out the reasons with crisp precision.
“Three main factors. First, the Hufu cavalry’s efforts prevented a complete encirclement.”
Though they could not inflict decisive damage, they brilliantly stopped the Zhang Dang army from fully surrounding the Zhao troops.
“Second, Zhao’s commander Bang Nan proved a better tactician than even Qin’s Zhang Dang.”
The Qin army had tried to defend its flank with a phalanx while punching through the front with an advancing wedge; Bang Nan’s defense halted them cold.
“Third, Lord Xinling and the Wei army’s aggressive advance forced the Zhang Dang army to split its attention.”
They could not ignore the threat that Lord Xinling might suddenly pivot and strike their rear. Already struggling to crack the tightly knit Zhao formation under Bang Nan’s command, the Qin general now had to watch two directions at once. What had begun as a one-sided Qin offensive gradually turned into a grinding, mutual contest of push and pull.
“If he calculated all of this in advance… then Lord Xinling truly possesses the greatest command under heaven,” Xiang Tai said, voicing exactly what I felt.
While we traded exclamations of wonder, the battle was rushing toward its conclusion. Once Biao Gong’s army collapsed before the combined Yan-Zhao-Chu forces, the Qin center began to waver. With their right flank gone, Meng Wu’s central army would surely suffer the same fate.
Yet Meng Wu was no fool who would simply abandon everything and let events run their course. A long note of retreat sounded from the Qin center. Having judged that victory could no longer be overturned, he chose to preserve as many soldiers as possible.
“We won…”
In a situation where every factor had been against them, Lord Xinling had seized victory by exploiting the Alliance’s two greatest advantages: his own unmatched reputation on this battlefield, and cavalry superior to Qin’s.
“Well, it was only natural,” Sima Shang said, outwardly calm. Yet even her voice carried a faint tremor of emotion. An unbelievable triumph. Even she, who had foreseen victory, could not help but be shaken by its scale.
But Qin remained Qin even in defeat. Their discipline was iron. At the retreat signal, suicide squads moved to the rear to cover the withdrawal, maintaining perfect order while executing a textbook fighting retreat. The Qin elite, men who had already accepted death, could not be broken easily; the Alliance, though riding a wave of momentum, was forced to spend a long time grinding through them.
Yet an army that had lost one of its wings could never stop the divine sword known as Lord Xinling—the blade forged by the world and tempered by every state beneath heaven.
“Pursue! Nations of the world! At last the moment of vengeance has come against Qin, who trampled your lands! Remember the atrocities of King Zhaoxiang! Three Jins! Men of Yan! Men of Chu! Now is the hour we deliver judgment upon Qin!!”
Lord Xinling’s cry cut through every sound on the battlefield and rolled all the way to our distant watchtower. Qin had once dared to invade even distant Yan. The hour had come to repay that debt in full.
