In the two years after the death of Duke Wen of Jin, the Jin Kingdom achieved a record of three wins and one draw in four confrontations with foreign enemies. It is simply unimaginable that such an impressive record should come from a country ruled by a mediocre and incompetent monarch.

The Qin people attributed this phenomenon to the remnants of Duke Wen of Jin, who firmly believed that the Jin state would decline in the near future. The people of Qin are welcoming this day with a positive attitude, and the Jin State has decided to warn the people of Qin with practical actions: "You are thinking wrong! In a state of mutual intransigence, the two countries broke out in the Battle of Pengya in February of the second year of the reign of Lu Wengong (BC625).

The cause of the battle of Peng Ya is still a mystery, and the historical records record that Meng Ming led his division to attack Jin, Jin Xianggong sent his division to resist, and Qin and Jin fought in Peng Ya. But Peng Ya is located in the territory of the Qin State, how can the Jin army go to the territory of the enemy country to resist the invasion? Therefore, it is very likely that this war was caused by the Jin State's initiative to carry out "invasion defense".

After the Jin State defeated the Wei State in Qidi, the Qin people decided to invade the Jin State after believing that they were well prepared enough. The Jin people were distressed when they received the information, because they were not sure that they would defeat a well-equipped, well-prepared, and high-morale tiger and wolf army.

The ministers of the Jin State were naturally divided into two factions, one group advocated a frontal battle, and the other group proposed to focus on defense or choose an opportunity to negotiate peace. Jin Xianggong was a man with no ambitions, he was dragged to the battlefield; The four wars in two years made him anxious, and he also broke his heart for the militants in the office.

This time, Jin Xianggong finally stood up and openly supported the defenders. But first he retorted and said: "Any enemy will gain an inch, and if this time it shows weakness, the Qin State will attack the five cities of Hexi next time; Rather than resist then, it is better to confront the enemy now. The first monarch Huigong was the weakest monarch, and he dared to fight with the Qin State; As the overlord of China, the prince actually wanted to escape, and after a hundred years, when he came to the sky, how to face the Duke of Xian and the Duke of Wen? ”

Due to the fact that Xian Jiju put the first monarch out to threaten, Jin Xianggong had no choice but to retract what he had just said and agreed with the opinion of the main battle faction. Zhao Yu said: "If we defend passively, we are not sure of victory; Therefore, it is better to take the initiative to attack, which will cause the offensive and defensive momentum to reverse, and our side will take the initiative, and the probability of victory will increase.

According to the analysis of the Jin people, the Qin army could only march east from Weinan through Taolinsai, and then look for a ferry to cross the Yellow River north. Therefore, the Jin people stationed a heavy army at the eastern end of Taolinsai and Sangtian on the south bank of the Yellow River, and strengthened the defense of Weicheng on the other side of Sangtian. The two fortresses, one south and one north, were able to contain the invasion of the Qin army from the south.

After that, the Duke of Jin Xianggong drove the expedition in person, but the command of the army was in the hands of Xian and Zhao Yuan. The Jin army crossed the Yellow River west at the Longmen Mountain Ferry and went straight to Shaoliang City in the northern part of the Qin State.

Qin Mugong had just assembled his army, but he didn't expect the Jin army to take the lead from the other direction, and the Qin army's plan of action was completely disrupted.

The Qin army had to turn north to meet the Jin army. The Jin army besieged Shaoliang City without attacking it, and after receiving the news that the enemy was coming, he lifted the siege of Shaoliang City, continued to advance westward, and set up camp near Peng Ya, preparing to start a decisive battle with the Qin army here.

Peng Ya is located on the east bank of Luoshui in present-day Shaanxi Baishui County, facing Shaoliang City from east to west, and is a strategic place to resist Bai Di's southward movement. The Qin army traveled day and night, crossing Jingshui and Luoshui, and reached the opposite side of the Jin army on February 6.

At this time, the Jin army had rested for several days, but the Qin army was exhausted. Xian Jiju decided not to give the Qin army a chance to recuperate, and he immediately sent a war letter to the Jin army, asking for a decisive battle the next day; Not to be outdone, Meng Ming immediately decided to fight. Meng Ming replied to the Jin people: "I promised to worship the Marquis of Jin for three years. Now that the time has come, since the ** team has come here, they don't have to travel a long distance, but they are here to worship the king! ”

At dawn on the second day, the warring sides set up their arrays. The Qin army was still outnumbered, but the soldiers were in high spirits, knocking on their weapons from time to time, and roaring angrily, ready to take revenge on the Paoze brothers who died in the battle at Kunshan.

The local army recruited from Peng Ya was the mobile force of the main force of the Qin army, and it was arranged far under the city. The Jin army did not react to the performance of the Qin army, perhaps they were used to this situation.

The royal Rong of Jin Xianggong is a royal official without land, and the right side of the car is the son of the fox Yan. First, he watched left and right to confirm that the arrays of the various teams had been arranged, and Meng Ming on the opposite side was also doing the same thing.

At this moment, several chariots burst out of the Jin army's formation, and the chariots were followed by sergeants who were flying like flying, and they shouted loudly and rushed straight into the enemy's military formation, completely indifferent to the spear blades of the Qin army, and completely indifferent to their own life and death. Xian Jiju didn't know what was going on, but he beat the drums of war, and the Jin army was inspired by the spirit of his comrades to die, and rushed into the enemy line like a tiger into a pack of wolves.

The Qin army had no expectation that the Jin army would use a suicidal charge, and although their bravery was not inferior to that of their opponents, and their combat skills had been perfected after years of hard training, they had no experience in dealing with suicide attacks.

The Qin army's defense line was immediately broken through several gaps, and the Qin soldiers who were at a loss could only fight on their own, but the formation limited their free play. The soldiers were huddled together, and there was no room for them to show; The front was slaughtered, but the enemy was not visible to the rear. The Jin army opened the battle line and attacked simultaneously from the front and flanks, and the entire army of the Qin army was compressed into a small area. The Jin people shouted: "Drive the people of the Qin State into Luoshui!" ”

But after a long time, the explosive power of the Jin army was exhausted, and the Qin army finally gained a foothold, re-established the defensive line, and pushed the enemy back little by little. At this time, the army under Peng Yacheng also rushed over to attack the rear of the Jin army, and the Jin army was afraid of being attacked from both sides, so it began to shrink its ranks.

The encircled Qin army finally joined up with the friendly forces, and the Jin army attacked again, but this time the attack was slow and powerful, and the Qin army retreated as they fought and finally retreated to Peng Yacheng.

The Jin people shouted at the defeated enemy: "I'm sorry, we didn't know that you were here to worship the king!" "The Jin army marched into the Qin army camp and seized a large number of baggage, miscellaneous labor, and livestock.

Immediately after the battle, the first and second place began to investigate which killer kid had committed the suicide attack and what the reason was. After the results of the investigation came out, all the Jin people burst into tears, and Jin Xianggong made an exception to upgrade the funeral of the victims.

The cause of the incident can be traced back to the time of the Battle of Kun.

At that time, after the Qin army was forced to surrender, a Qin warrior named "Bao Manzi" preferred to die rather than surrender, and he was subdued due to physical exhaustion after killing many Jin people.

Jin Xianggong admired his bravery and promised that as long as he surrendered, he could be given the position of doctor. But Bao Manzi scolded him to the point of blood, saying that he would never give an errand to a prostitute who would not even let go of his mother (Jin Wengong's harem is equivalent to Jin Xianggong's mother). Jin Xianggong was furious and immediately ordered Che You Laiju to kill him.

Laiju jumped out of the chariot and rushed to the Bao Manzi with Ge in his hand; The man roared angrily, and Laiju trembled, and the weapon in his hand fell to the ground.

Jin Xianggong's face was full of anger and shouted: "Coward! He twisted his face and drove away without looking back. There was a sergeant named Wolf in the guard, who suddenly rushed out of the queue, drew his sword and cut the neck of Bao Manzi, then grabbed Laiju by the collar and hurriedly jumped into the chariot of Jin Xianggong. Jin Xianggong praised Wolf Yao and immediately appointed him as the right car.
