In history, after Deng Aidu's Yinping, the defenders of Jiangyou and Fucheng were afraid and surrendered without fighting, which prevented Deng Ai's troops from being consumed. Later, Deng Ai fought with Zhuge Zhan and his son in Mianzhu and won in one battle. Zhuge Zhan and his son died. Seeing that the situation was hopeless, Liu Chan surrendered to Wei.
Now, Gao Shun first fought a fierce battle with the ambushers in Yizhou at the exit of Yinping Road, and then lost hundreds of people when attacking Fucheng, so that Gao Shun had no advantage in military strength when attacking Mianzhu.
What was even more unfortunate for Gao Shun was that the general stationed in Mianzhu at this time was Li Yan. Li Yan, a famous general, was good at fighting and both wise and brave. When Deng Ai attacked Mianzhu, although Zhuge Zhan, the general whom he faced, was the son of Zhuge Liang, did not inherit Zhuge Liang's amazing talent, and his military talent was far inferior to Li Yan. Li Yan guarded Mianzhu, so naturally Gao Shun would not easily break it.
It can be said that the situation Gao Shun is facing is completely incomparable to Deng Ai, and the difficulty level has increased several times.
Gao Shun has now realized that he had thought things too simply at the beginning, thinking that Deng Ai could successfully destroy Shu and that he could do it, but along the way, he suffered repeated setbacks.
Deng Ai successfully destroyed Shu, and it has to be said that he had his own luck, but Gao Shun seemed to have no good luck.
Seeing that Mianzhu was well-defended, Gao Shun did not dare to launch an offensive rashly. After all, one of his soldiers was killed by him now. If he failed to break through the city and lost hundreds of people, his situation would be even more difficult.
If the battlefield was in other places, Gao Shun probably would have retreated long ago. After all, Mianzhu has no hope of conquering, and continuing to move forward has become a luxury, and it is basically no possibility to win.
But now, Gao Shun is in the Jedi. Even if he wants to retreat, where can he retreat? It is not easy for him to lead his army to pass Yinping, but there is no possibility of returning as the same way.
It can be said that Gao Shun's trapped camp has lost all retreat since the moment it rolled down on the cliff in Yinping. If it cannot move forward, there is probably only a dead end to waiting for Gao Shun and his trapped camp.
Gao Shun could only temporarily station the camp in Fucheng, but this was not a long-term solution. It was difficult to solve the problem of food and grass alone. When Gao Shun attacked the city, the defenders of Fucheng saw that the city was about to fall and asked to set fire to the fire. Although Gao Shun tried his best to save the food after breaking the city, most of the food and grass were burned. Although the number of people in the camp was only 1,500, the food and grass in the city was pitifully small. Now the remaining food and grass in the grain silo in Fucheng may only last for six or seven days. And trapped in the isolated city, in addition to food and grass, various other troubles and difficulties are also emerging one after another.
But Gao Shun had no other way, he had completely lost ground.
In fact, as far as the current situation is concerned, withdrawing Jiangyou is still a good choice. There is still a lot of surplus grain in Jiangyou City, which can support this camp for at least one month. Unfortunately, Gao Shun's mood is a little disorganized at this moment and has not been able to take this into consideration.
In addition, withdrawing Jiangyou from Fucheng means that Gao Shun will completely give up his plan to attack Chengdu. Moreover, even if Gao Shun retreats to Jiangyou, the Yizhou army can be transferred from Mianzhu to Fucheng. In addition to obtaining more food, the dilemma faced by the camp has not changed substantially.
The current camp has completely become an isolated army, one alone army trapped in the Jedi, and one alone army that may be wiped out if you are not careful.
After learning that an army had passed Yinping and conquered Jiangyou and Fucheng, Zhang Ren quickly responded.
Zhang Ren immediately ordered Leng Bao to lead 5,000 troops back to Chengdu.
Zhang Ren also knew almost the reality of the Cao army outside Jiange Pass. At least Zhang Ren knew very well that there were definitely not many Cao army stationed outside Jiange. It was nothing to allocate these five thousand people.
Even if there were only 20,000 people in Jiange Pass, Zhang Ren dared to make sure that he would not lose. What's more, after Leng Bao led his army away, there were still 40,000 Yizhou soldiers left in Jiange.
Unless a miracle was brought to heaven, there was no possibility of Cao's army breaking the barrier.
As for the Cao army that had survived Yinping, Zhang Ren was not worried at all. Although he didn't know how the other party won the battle with the ambush and defeated Jiangyou and Fucheng, what Zhang Ren dared to be sure of was that if he could achieve such results, the Cao army would have to pay a huge price. Now it is most likely that he is at the end of his strength and it is impossible to make any progress. What's more, there are also generals like Li Yan in Chengdu.
Leng Bao led 5,000 people back to Chengdu, and Chengdu would be safe and sound, and it would even be possible to wipe out the surprise weapon.
From Zhang Ren's point of view, Cao's army sent troops this time was really hasty, and there was nothing too much to be afraid of.
Although the troops in Yizhou, in terms of quantity and combat power, could not compete with Cao's army, which had conquered most of the country, in terms of this war, Zhang Ren felt that there was no possibility of Yizhou in any way that would lead to failure.
What we need to worry about now is not the Cao army in front of us, but the next revenge operation of Cao Cao after defeating this Cao army, but that is something that needs to be considered after the war is over.
