Zhao Ding Han defeated the Qin army, and joined forces with Shi Quan to pursue the Shu soldiers.
Here is the translation:
As for King Huai of Chu, 100,000 Chu soldiers clashed with 100,000 Qin soldiers in a single location. Within this location, there were two separate battles: one between 30,000 cavalrymen from both sides and another between 70,000 infantrymen from both sides.
This was a one-on-one showdown, as well as a fight to the death. The Chu army, inspired by King Huai's bravery, fought with great enthusiasm, becoming more courageous as the battle raged on. They had already killed three Qin generals in succession and were now pressing their advantage.
The Qin army, on the other hand, was demoralized after suffering consecutive defeats. Even Sima Cuo, the top general of Qin, had been beaten by King Huai to the point where he almost lost his life. As a result, the Qin soldiers' morale was low, and they were being pushed back by the Chu army.
King Huai saw this and charged forward on horseback, sweeping aside thousands of Qin cavalrymen with his long spear. The Qin horses fell or were severely injured, unable to withstand the attack. A gap opened up in the Qin formation, and no one could stop it.
With his spear, King Huai aimed directly at King Huiwen of Qin. Sima Cuo saw this and shouted, "Not good!" He swung his large knife with all his might, fighting desperately to protect his king. Clang! Clang! Clang!
Sima Cuo ignored the pain in his arm and fought hard to block King Huai's three consecutive attacks. Earlier, he had already been forced back three steps by King Huai, his palm and tiger mouth bleeding profusely. How could he withstand these powerful blows now? This was a testament to his loyalty and willingness to die for his king.
King Huai shouted loudly as he struck with all his might. Sima Cuo knew he couldn't resist the attack and shouted, "Your Majesty, please escape!" Using all his strength, he tried to block King Huai's blow.
The two clashed, and Sima Cuo was knocked back three steps, his large knife flying out of his hand and landing a yard away. It happened to land on a Qin general who was rushing over to rescue the king, beheading him in the process.
King Huiwen of Qin was frightened, his face turned pale, and he hastily retreated on horseback. At this time, the Qin cavalry saw the situation and rushed to rescue their king. As a result, the Qin army's cavalry formation suddenly became chaotic, and King Huai of Chu wielded his long spear, sweeping left and right, front and back, causing the Qin cavalry to fall off their horses one after another.
The Chu army saw King Huai charge into the enemy array, and 30,000 iron cavalry followed him in a desperate charge. The Qin army's formation was already chaotic, unable to withstand the Chu cavalry's desperate impact, and they retreated in disorder. King Huai held his spear horizontally with his left hand and drew out the sword of the king of Chu with his right hand, slashing left and right.
This King Huai's sword chopped down on the helmet of a Qin cavalryman, splitting both the helmet and the head into two halves. Several long spears of the Qin cavalry thrust forward, but King Huai's precious sword swept them aside, cutting off the spears. In an instant, dozens of Chu generals and cavalrymen rushed to King Huai's side to protect him, killing all the Qin cavalry who had approached.
Hundreds and thousands of Chu cavalrymen charged towards the Qin cavalry surrounding King Huai. The 30,000 Qin cavalry saw King Huiwen of Qin and his commander-in-chief, Sima Cuo, fleeing in retreat, and they hastily rushed to their side to protect them. Suddenly, the Qin cavalry's formation was completely chaotic, unable to withstand the Chu cavalry's attack.
The Chu cavalry took advantage of the situation to launch a pincer movement, killing and wounding countless Qin cavalrymen, causing them to flee in defeat. King Huai saw this and ordered 10,000 iron cavalry to charge forward and attack the Qin army infantry. The 70,000-strong Qin army infantry was engaged in fierce combat with the Chu army infantry when they were suddenly charged by the 10,000-strong Chu cavalry.
The Qin army infantry fell down one after another, and the Chu army infantry surged forward like a raging tide, killing the Qin army. Suddenly, more than half of the Qin army infantry was killed or wounded, and their entire line collapsed in defeat. The Qin army cavalry saw this and hastily turned around to charge back and cover the retreat of their infantry.
King Huai personally led 20,000 iron cavalry to intercept them, while the 10,000-strong Chu cavalry that had charged into the Qin army infantry formation turned around and charged towards the Qin cavalry. King Huiwen of Qin saw this and hastily ordered his entire army to retreat quickly. The Chu army took advantage of the situation to launch a pincer movement, killing and wounding more than half of the Qin army.
Afterwards, King Huai personally led an army of 100,000 men, both cavalry and infantry, in pursuit of the Qin army for 40 li, until they reached Shiquan County (present-day Shiquan County), where they finally stopped to rest and have a meal.
On this side, the 100,000-strong Chu army and the several hundred thousand Shu army fought as one. In terms of military strength, the Shu army had a few more tens of thousands, but the Shu army's cavalry was only 25,000, which was 5,000 less than the Chu army's cavalry. Moreover, the Shu generals were no match for Zhao Yu, who had defeated two Shu generals with his spear. As a result, the morale of the Shu army was low, while the Chu army saw Zhao Yu defeat the Shu Hou and kill two high-ranking Shu generals in succession, their morale soared instantly. In the fierce battle, the most important thing was the overall morale of the army. The difference in morale between the Chu and Shu armies was that the Shu army was defeated by the Chu army and retreated continuously, unable to hold its ground. Zhao Yu's long spear was invincible, and he swept and pierced his way through, killing over a dozen Shu cavalrymen in a row. The Shu cavalry saw this and retreated in disarray, fleeing left and right. After the 30,000-strong Chu iron cavalry charged forward, the Shu army's cavalry formation was completely disrupted, and both sides fell into chaos. The cavalry had always been at a disadvantage for the Shu army, and after such a disruption, they naturally suffered heavy casualties. Zhao Yu saw this and assessed the situation, dispatching 10,000 Chu cavalry to attack the Shu infantry from the side. These 10,000 Chu cavalrymen rushed towards the Shu infantry's flank, charging into the Shu infantry formation. Although the Shu infantry was numerous, they could not withstand the left and right attacks of the 10,000-strong Chu cavalry. Instantly, the Shu infantry formation fell into chaos, and the Chu infantry in front saw this and charged forward like a tidal wave to slaughter the Shu infantry. The Shu army could no longer resist, retreating in disarray with heavy casualties. When the Marquis of Shu saw that his army was defeated, he knew that all was lost and hastily ordered his cavalry and infantry to retreat quickly. The Chu army took advantage of this to launch a pursuit attack, killing over half of the Shu army. Zhao Yu then led his main force in pursuit of the Shu army for 40 miles, almost simultaneously joining forces with King Huai of Chu at Shiquan (present-day Shiquan County).
King Hui of Chu saw the arrival of Zhao Yue's large army and Zhao Yue said to King Hui, "The enemy has just been defeated, with more than half casualties. The combined forces of Qin and Shu have only 100,000 left, they are like a frightened bird. If we don't pursue them now, when will we? I've been chasing and killing the Shu army all the way here, so I ordered my soldiers to capture over 10,000 war horses. Now my 10,000 infantry has become cavalry." King Hui was delighted and said, "Well done! You're really something. On my side, I also captured over 10,000 Qin cavalry warhorses. It seems our battle results are equal, haha! What you said is exactly what I wanted to hear. Now the enemy must be cooking not far ahead. If we launch a surprise attack with our cavalry now, not only can we catch them off guard, but maybe we can even eat their free food!" Zhao Yue said, "Right! I'll lead 50,000 cavalry to charge forward and 50,000 infantry will follow behind. Your Majesty can lead the main force to follow up." King Hui said, "Good!" Then he ordered the whole army to bring enough dry rations for one day. Zhao Yue led 50,000 cavalry and 50,000 infantry in front, while King Hui personally led the main force to follow behind.
At this time, the Chu army was no longer 200,000, but 180,000, with an additional 10,000 wounded soldiers. In the Battle of Han 'Yin', both the Qin and Shu armies suffered 50,000 casualties each, while the Chu army suffered 30,000 casualties. However, at this time, the Chu cavalry was no longer 60,000, but 80,000. In the Battle of Han 'Yin', both the Qin and Shu armies' cavalry suffered over 10,000 casualties each, while the Chu cavalry suffered 10,000 casualties, but they captured over 20,000 war horses from Qin and Shu, so the Chu cavalry became 80,000 strong. Half an hour later, the Chu army had finished eating and drinking, everything was ready, Xiang Yu led 50,000 Chu cavalry and 50,000 infantry to rapidly pursue forward, King Huai of Chu led 30,000 iron cavalry and a large group of soldiers followed behind, over 10,000 wounded soldiers were escorted by grain carts.
