Before the Battle of Changping, the State of Qin formulated a "half-Korean" strategy to occupy half of Korea's territory, that is, to capture Shangdang County, Korea.
The terrain of South Korea is like a gourd, with large upper and lower ends and small in the middle. The State of Qin planned to storm the forts in the narrow areas of central Korea, and finally capture the city of Yewang in the central part, dividing Korea into the area under the jurisdiction of Chengdu City Xinzheng and the two pieces of land in the north and south of Shangdang County, so that Shangdang County would become an enclave of Korea, and then force Korea to hand over the big cake of Shangdang County, and the Qin State would be able to occupy half of Korea's territory.
In 262 BC, the Qin army captured the core city of Hanoi County. Yewang was the confluence of Danshui and Qinshui, and the Qin army captured it, not only taking all of Hanoi County, but also completely cutting off the water passage from Mainland Korea to Shangdang County.
For three consecutive years, Wu Anjun, the first general of the Warring States, frantically attacked the central Fortress of Korea, and finally divided Korea in two, completing the most difficult step of the "half-Korea" strategy.
However, the Korean Shangdang Taishou Feng Ting refused to surrender and vowed to fight the Qin army to the end. Under the "tight pressure" of King Huanhui of Han, Feng Ting made a superior strategy: to dedicate Shangdang County to the Zhao State. This move ignited the fuse of the largest battle of the Warring States, the Battle of Changping of Qin and Zhao.
After Zhao Guo took over shangdang, he immediately launched a large-scale military operation, and the brave general Lian Po personally took command, and more than 100,000 troops went to Shangdang (and later increased troops).
Zhao Guo's army marched into Shangdang, but seeing that the flag was hidden in the wilderness, the swords were in the air, and the people were like fierce tigers and Maasai flying dragons, and they could go up to the remaining seventeen cities of Dang County without a fight, and the generals of the Zhao Army were in a happy mood.
The deployment of the Zhao army in the Upper Party was concentrated in the geographical plate of the Eastern Shangdang, and since the Beishang Party's tunliu did not need to directly face the Qin Army, Changping of the Eastern Shangdang became the main deployment site of the Zhao Army. After that, the Battle of Changping was carried out around the plate of Changping.
Now let's take a look at Zhao Jun's deployment in Changping:
In 262 BC, due to the old age and illness of Wu An Junbai, King Zhaoxiang of Qin ordered the second-in-command of the Qin army to reorganize the army and horses at Hanoi County, and attacked the former Shangdang County, Korea.
If the Qin army attacked from the direction of "3 Baixing", it would face the Empty Cangling Defense Line in the western part of the Zhao Army. Khlong CangLing is a north-south mountain with a rocky mountain and a steep ridge. This mountain ridge winds from north to south for more than 80 miles, and in the middle of the ridge there is a canyon that runs through the east and west, and the Rok army has long built Gaoping Pass because of the terrain.
Gaoping Pass is steep and unusual, with cliffs to the south and steep streams to the north, but the middle canyon runs through the east and west. This canyon is about one mile long from east to west and about two miles wide from north to south, and it is the key place for zhao jun's throat.
To the east of Gaoping Pass, Zhao Junyi built Zhao Jia into two cities, forming a horn with Gaoping Pass, and could support Gaoping Pass at any time.
Why are two cities built behind Xiongguan? Because the scale of Gaoping Pass is not as large as that of Hangu Pass and WuGuan, the number of non-commissioned officers that can be accommodated is only about 5,000, and once the war begins, the casualties on Gaoping Pass can be replaced by the soldiers of the two cities.
This weakness of Gao Pingguan was discovered by the keen Wang Gong and a tactic was formulated for this purpose.
Wang Gong ordered the Qin army to create a momentum in situ, and then led the main force to detour from Hanoi County back to Ha Dong County, then from "3 BaiXing" to the Taihang Mountains, and finally attacked Gaoping Pass.
In the big tent of the Qin army, Wang Gong was full of ambition, gathered a cadre of generals, and loudly said: "A good boy has made meritorious achievements, and it is at this time!" ”
The generals were all boiling with blood, shouting the bold words of "stepping on the Zhao Kingdom", and the big tent was surrounded by the fur of the beasts of Shangdang County, and the jackals, wolves, tigers and leopards were all there, and they looked at this group of excited humans one by one, knowing that a big war was about to begin.
On the side of the Zhao army, Zhao Jia found that the Qin army had launched an attack from the west, so he personally sat at Gaoping Pass and pointed the needle at Mai Mang. Zhao Jia appeared at Gaoping Pass, the first line of the war, which greatly boosted the morale of the Zhao army, and everyone was enthusiastic and wanted to fight with the Qin army to the death.
However, Zhao Jia did not expect that the Qin army's attack on Gaopingguan this time was not the vanguard force, but the main force of Wang Gong, and the number was dozens of times that of the Zhao army.
When the Qin army launched a ferocious attack throughout the mountains, Zhao Jia was accidentally killed by a stray arrow. The group of dragons was leaderless, and in the short term, it had a serious psychological impact on zhao jun in the short term.
Wang Gong's sharp eyes immediately saw the strange appearance on Gao Pingguan, how could he give Zhao Jun a chance to breathe, and immediately ordered to take turns to attack day and night. Before the Zhao general Lian Po could send someone to take over the first line of defense, Gaoping Pass was conquered by the Qin army, and all five thousand Zhao troops were martyred in the line of duty.
Starting from Gaoping Pass, the Zhao Army's defensive line was Gaoping Pass, EryanCheng, and Guangwolf City, a three-in-one defense system, and now that Gaoping Pass has been broken, the erhe city and Guangwolf City behind it have no dangerous mountains to rely on, and it is only a matter of time before they are lost. The Great Wall defense line on the southern front of the Zhao Army is also likely to be disintegrated from the inside by the Qin Army.
At this time, Lian Po took advantage of the opportunity of the Qin army's rest to transfer all the Zhao troops on the southern front back to the east bank of the Dan River, abandoning the first line of defense and sticking to the second line of defense.
Of course, Wang Gong was well aware of Lian Po's intentions, and he ordered all the soldiers who could stand to advance further eastward in an attempt to expand the results of the battle when the Zhao army retreated.
In order to allow the 20,000 Zhao troops of the Southern Great Wall to successfully retreat to the east bank of the Dan River, the Zhao defenders of Eryan City and Guangwolf City had no intention of retreating at all, and they regarded death as a homecoming and fought until the last drop of blood was shed.
Within a few months, the Qin army under Wang Gong's command won consecutive victories, and the Zhao army under the command of Lian Po lost all the territory west of the Dan River in Shangdang County, lost one general, Zhao Jia, and six lieutenants, and killed more than 30,000 soldiers.
Lian Po only stationed a few tens of thousands of people west of the Dan River, so the Zhao army could bear the loss this time. What is even more valuable is that in the case of continuous defeat, Lian Po organized a second line of defense for the Zhao army on the east bank of the Dan River, and blocked the Qin army from advancing eastward at the Dan River.
But what no one expected was that this confrontation, bounded by the Dan River, lasted from 262 BC to 260 BC. The zhao and Qin armies continued to increase their troops, with the total strength of the Qin army being about 500,000 and the Zhao army exceeding 400,000. The two sides had 900,000 soldiers, which made the other princely states ashamed. Both King Xiaocheng of Zhao and King Zhaoxiang of Qin wanted to decide the victory and defeat as soon as possible, and the two countries had been overwhelmed by this protracted war.
What is the harm of protracted warfare? Since hundreds of thousands of troops on both sides could not leave Shangdang County, the army consumed a large amount of military food and materials every day. As a result, domestic agricultural production is lagging behind, commerce is sluggish, the people are miserable, almost every family has a husband or son in the military, and social problems are endless.
The agricultural foundation of the Zhao state was not as good as that of the Qin state, and the northern counties of Wuyuan, Jiuyuan, Yunzhong, Yanmen, and Dai counties accounted for half of the area of the Zhao state, but there was no farming and could not provide grain. On weekdays, these places also had to transfer grain from all over the Central Plains, so Zhao Guo had to buy grain from other countries at high prices, resulting in an empty treasury, and King Zhao Xiaocheng was miserable.
If the Qin and Zhao armies spent another three years on both sides of the Dan River, the Qin state would be depleted and the Zhao congress would be consumed.

The commander of the Zhao Army, Lian Po, sat on a boulder, majestic as a mountain, and the boulder, the mountain, the sunset, Wei Ran, his prestige in the Zhao army was like a needle in the sea god. Lian Po looked down at the Qin army's camp on the other side for tens of miles and fell into contemplation.
Lian Po looked at the situation on the other side, the black flag that was still flying faintly, and he could not find the flaws of the Qin army, and a trace of uneasiness surged in his heart. King Xiaocheng of Zhao sent people to urge the battle several times, and Lian Po repeatedly disobeyed the order to go to war, feeling that the fate was involuntary, and his heart was worried, what would be the fate of him and Zhao Jun?
