At the Battle of Changping, after Zhao Kuo replaced Lian Po, he led the Zhao army across the Dan River to counterattack. The front of the Zhao army surged forward, like a gust of wind, rushing towards the Qin army's barrier.
The State of Qin also replaced Wang Gong with Bai Qi, and the Light Wolf City and the nearby barriers, the wood and stones fell together, and tens of thousands of people in the front of the Zhao army had to be limited to stagnation.
Zhao Kuo judged the situation and ordered a full line of retreat. In the art of war, it is said that "if it is unfavorable, it will be retreated", and Zhao Kuo has nothing to say about using the art of war.
At the same time that the Zhao army achieved a partial victory, Wu'an Jun's white two-way divine soldiers descended from the sky and sneaked down from both sides to sneak into the rear of the East Bank of the Dan River of the Zhao Army.
The first Qin army, led by Sima Terrier, with 25,000 men, circled from the northeast to the back of the Zhao Army's Hundred Mile Stone Great Wall, cutting off the Changping Zhao Army's ties with Handan and the Party in the north.
On the second road, the Qin army, Wang Ling led five thousand light cavalry across the Dan River, cutting off the connection between the Zhao army in Changping and the DaliangShan, which was where the Zhao army was storing grain, and although the Qin army could not occupy the Daliangshan, it was feasible to cut off the road.
With the deepening of the battle situation, Bai Qi also continued to increase the number of troops for these two divine armies, trying to trap the Zhao army.
In turn, the Zhao army retreated, and the Qin army pursued. In the process of the Zhao army's retreat, Wang Gong was able to let the Zhao army retreat safely, and he led the Qin army to launch an oppressive pursuit of the Zhao army, not allowing the Zhao army to return to the east bank of the Dan River, and also buying time for the two divine soldiers.
While setting fire to the forest, the Zhao army laid traps on the other, broke off with strong crossbowmen, and retreated in an orderly manner. Although the Qin army could slow down the pace of the Zhao army, it failed to kill the Zhao army on a large scale.
The Zhao army commanded by Zhao Kuo, after paying a certain price, the main force still crossed the Dan River and returned to the Changping camp.
In the process of this attack and retreat, the Zhao army suffered a lot of losses, at least tens of thousands of people were killed, and the losses of the Qin army were even greater.
However, the losses of the Qin army were definitely worth it, and just as the Zhao army was retreating to the Changping camp, the Qin army Sima Terrier attacked the Baili stone Great Wall in the north, and the Wang Ling department cut off the communication between Daliangshan and the Changping camp.
Now the pattern of the battlefield is very different, just in the process of the Zhao army's attack and retreat, the Qin army has completed the strategic encirclement of the Zhao army, limiting the Zhao army to the triangle area of the Bailishi Great Wall, the Dan River, and the Xiaodongcang River Valley.
Now that the Zhao army has lost contact with the grain depots in Daliangshan, if the Zhao army wants to open up the grain route, it must control the Xiaodongcang River Valley. However, although the water of the Xiaodongcang River Valley is not deep, the cliffs on both sides are rocky and rocky, and there is nothing but a few weeds that occasionally emerge.
To transport grain and grass in the small Dongcang River Valley, where there was no hiding place, the Zhao army knew that the guanshan was difficult to cross, and had to break through bravely. Zhao Kuo ordered some of the Zhao troops to break through in the direction of the BailiShi Great Wall and the Dan River respectively to attract the attention of the Qin army, but sent a crack army to the Daliang Mountain to forcibly transport grain and grass.
But the commander of the Qin army was Bai Qi, who could be so good at fooling, Bai Qi anchored the Lack of food for the Zhao Army, and the place where he increased his troops the most was the Xiaodongcang River Valley.
The Zhao army struggled to rush to transport grain, the Qin army desperately blocked, and the two armies launched a fierce battle in the Xiaodongcang River Valley, and the shouts in the river and on the shore were boiling, and the killing sound was tremendous.
In the small Dongcang River Valley, the corpses accumulated in the river channel, the blood flowed into a canal, and a very small number of Zhao Jun's bloody robes and armor only carried a few bags of grain and grass back to the Changping camp.
There were still 300,000 people in the Zhao Army's camp, and there were more than three hundred centurions alone, and this grain was also the rations of the centurions, and even the urgent needs of the Zhao Army could not be solved.
Bai Qi ordered the Qin army to guard the key roads of various mountain passes, build barriers, and trap more than 300,000 Zhao troops in Changping.
Although Bai Qi used soldiers like gods, the Qin army had not yet won at this time, and in terms of casualties, the Qin army was still greater than the Zhao army, but the Qin army began to grasp the initiative of the battlefield.
