Han Yan defeated Sima Chuai
Here is the translation:
Furthermore, Zhao Yue rode his horse and held up his spear to directly attack the Marquis of Shu. The Marquis of Shu raised his twin forks and rode over to meet him in battle. This Zhao Yue was a tall and sturdy man, this year being thirty-three (two years younger than King Huai of Chu), his strength may not have been as great as King Huai's, but his spear skills were truly divine. In less than ten rounds, the sound of "ding" rang out, and the Marquis of Shu's left hand steel fork flew out of his hand, scaring him into retreating on horseback.
Two Shu generals rushed over to protect their lord, Zhao Yue let out a loud shout, and with one long spear, swept across thousands of soldiers. The two Shu generals, one wielding a spear and the other a sword, raised their weapons to block his attack. The three clashed in a fierce battle. This Zhao Yue fought against two opponents at once, his long spear thrusting left and right, his movements swift and deadly.
Zhao Yue's spear techniques were varied and unpredictable, causing the two Shu generals to dodge and weave, blocking his attacks repeatedly. Just as it seemed that Zhao Yue's spear was about to sweep to the right, the right-hand Shu general hastily raised his sword to block, while the left-hand Shu general saw an opportunity to attack.
But little did they know, Zhao Yue's previous move was a feint, intentionally revealing an opening to lure the left-hand Shu general into attacking. As the spear tip approached the right-hand Shu general's chest, he suddenly turned and swept his spear towards the left-hand Shu general. His body dodged to the left, avoiding both the left-hand Shu general's spear and the right-hand Shu general's sword.
The right-hand Shu general's sword happened to strike the head of the left-hand Shu general's spear, just as Zhao Yue's spear tip was about to pierce the left-hand Shu general's chest. The left-hand Shu general cried out in alarm, but his body couldn't dodge quickly enough and he was stabbed in the right shoulder.
Zhao Yue's long spear thrust upwards, sending the left-hand Shu general tumbling off his horse. The right-hand Shu general saw this and hastily swung his large sword to strike down Zhao Yue. But Zhao Yue's long spear swept towards him, colliding with the sword and sending it flying away with a loud "ding".
Zhao Yue's spear transformed into an attack, its tip darting left and right, up and down. The sound of "peng" rang out as one spear thrust pierced the right-hand Shu general's heart. Although this Shu general wore armor, Zhao Yue's spear may not have penetrated his breastplate, but it still dealt a massive shock to his heart.
The Shu general felt an intense pain in his chest, and his body swayed before falling over. Zhao Yue's long spear flashed out once more, striking the Shu general's cheek. The Shu general let out a cry of despair as he fell off his horse, losing his life.
The Shu army was stunned into silence, their morale plummeting. In contrast, the Chu army erupted in a frenzy of killing, with Zhao Yue at the forefront, shouting "Kill!" as he charged towards the enemy lines. The three thousand iron cavalry and seven thousand infantrymen of the Chu army followed close behind, charging towards the Shu army to slaughter them.
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 iron cavalry from both sides and another between 70,000 infantrymen from both sides. This was a one-on-one showdown, a fight to the death.
The Chu army, inspired by King Huai's bravery, fought with great enthusiasm, killing three Qin generals in succession. The Qin army, on the other hand, had been defeated repeatedly, and their commander, Sima Cuo, who was known as the bravest warrior of Qin, had almost lost his life at the hands of King Huai.
As a result, the morale of the Qin army was low, and they were constantly retreating. Seeing this, King Huai charged forward on horseback, sweeping aside thousands of Qin cavalry with his long spear. The Qin soldiers who tried to block him were either killed or severely injured.
The 30,000-strong cavalry formation was torn apart, leaving a huge gap that no one could fill. King Huai's long spear pierced through the ranks, heading straight for King Huiwen of Qin. Sima Cuo saw this and shouted, "Not good!" He swung his large knife with all his might, fighting to protect his king.
The sound of clashing steel echoed through the air as Sima Cuo desperately tried to block King Huai's three consecutive attacks. Earlier, Sima Cuo had already been forced to retreat three steps after being wounded by King Huai in a fierce battle, and now he was struggling to withstand the king's powerful blows.
King Huai's attack was relentless, and Sima Cuo knew that he couldn't resist any longer. He shouted, "Your Majesty, please escape!" Using all his strength, he tried to block King Huai's final blow.
The two clashed, and Sima Cuo was sent flying backward on horseback, his large knife knocked out of his hand and flying several feet away. It landed on a Qin general who had rushed over to rescue the king, beheading him instantly.
King Huiwen of Qin was frightened and his face turned pale, he hastily patted the horse to escape. At this time, the Qin cavalry saw the situation and rushed to rescue him, causing the Qin army's horse array to suddenly become chaotic. King Huai of Chu wielded a long spear, sweeping left and right, front and back, and the Qin cavalry fell off their horses one after another.
The Chu army saw King Huai of Chu charge into the enemy formation, and 30,000 iron cavalry followed him in a desperate charge, the Qin army's array was already chaotic, unable to withstand the desperate impact of the Chu cavalry, and retreated in disorder. King Huai of Chu held his spear horizontally with his left hand, and drew out the sword of the king of Chu with his right hand, chopping and killing left and right.
This King Huai of Chu swung his sword at the helmet of a Qin cavalryman, and actually split the head of this Qin cavalryman in two along with his helmet. Several long spears of the Qin cavalry thrust forward, and King Huai of Chu's precious sword swept across, cutting off the Qin cavalry's long spears.
In an instant, dozens of Chu generals and cavalrymen had rushed to King Huai of Chu's side to protect him, beheading all the Qin cavalry who had rushed up. Hundreds and thousands of Chu cavalrymen charged towards the Qin cavalry surrounding King Huai of Chu.
The 30,000 Qin cavalry saw King Huiwen of Qin and General Sima Cuo fleeing in retreat, and hastily rushed to their side to protect them. Suddenly, the entire Qin cavalry formation was thrown into chaos, unable to withstand the attack of the Chu cavalry. The Chu cavalry took advantage of the situation to launch a pincer movement, killing and wounding countless Qin cavalrymen.
The entire line of Qin cavalry collapsed in defeat. King Huai of Chu saw this and immediately ordered 10,000 iron cavalry to take advantage of the momentum to charge at the Qin army's infantry. The 70,000-strong Qin army infantry was engaged in a fierce battle 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, slaughtering the Qin army. Suddenly, more than half of the Qin army infantry was killed or wounded, and the entire line collapsed in defeat.
The Qin army cavalry saw this and hastily turned around to charge back, covering the retreat of their infantry. King Huai of Chu personally led 20,000 iron cavalry to intercept them, and the 10,000-strong Chu cavalry that had charged at the Qin army infantry earlier turned around to charge at 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.
Next, King Huai of Chu 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, 100,000 Chu troops and over a million Shu troops clashed. In terms of military strength, the Shu army had several tens of thousands more, but the Shu cavalry was only 25,000, which was 5,000 less than the Chu 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's consecutive victories over the Shu Hou and the defeat of two high-ranking Shu generals, which greatly boosted their morale.
The two armies clashed, and the most important factor was the morale of the entire army. The difference in morale between the Chu and Shu armies led to the Shu army being defeated by the Chu army, with the Shu army retreating repeatedly and unable to hold its ground. Zhao Yu's long spear was unbeatable, and he swept and pierced his way through the battlefield, killing over a dozen Shu cavalrymen. The Shu cavalry saw this and retreated in disarray.
After the 30,000-strong Chu iron cavalry charged forward, the Shu army's cavalry formation was completely disrupted, and the two armies became embroiled in a chaotic battle. The Shu cavalry was already at a disadvantage, and after being thrown into chaos, they suffered heavy casualties.
Zhao Yu saw this and assessed the situation, then dispatched 10,000 Chu cavalry to attack the Shu army's infantry from the side. These 10,000 Chu cavalrymen rushed towards the Shu infantry's flank, charging into their 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 surged forward like a tidal wave to attack the Shu infantry. The Shu army could no longer resist, and they retreated in disarray, suffering heavy casualties.
The King of Shu saw that his army was defeated and knew that the situation was hopeless, so he hastily ordered his cavalry and infantry to retreat quickly. The Chu army took advantage of this and launched a pursuit, 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 meeting up with King Huai of Chu's main force at Shi Quan (present-day Shi Quan 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 attack with 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 after." 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 the Qin and Shu armies, so the Chu cavalry became 80,000 strong. Half an hour later, the Chu army had finished eating and drinking, everything was ready, and Zhao She led 50,000 Chu cavalry and 50,000 infantry to rapidly pursue forward, while King Huai of Chu led 30,000 iron cavalry and a large contingent of troops followed behind, with over 10,000 wounded soldiers escorting the grain carts.
