In 228, Zhuge Liang tun troops in Hanzhong, and then began to send troops to the Northern Expedition, when he asked Zhao Yun and Deng Zhi to set up suspicious troops in Xiegu to attract Cao Wei's main army, when the Wei Ming Emperor Cao Rui was really deceived, he immediately ordered Cao Zhen to lead the various armies of Guan Right to resist Zhao Yun, and Zhuge Liang took this opportunity to lead the main army to attack Qishan. Since the State of Wei had been defenseless before, they heard that Zhuge Liang was coming with a large army, and three of the five counties of Longyou surrendered to Shu Han. In order to occupy Longyou, Zhuge Liang sent Ma Mozhen to guard the street pavilion to cut off the Wei army's reinforcements. However, Ma Mo did not deploy according to Zhuge Liang's request, and he mistakenly stationed the large army on the mountain, resulting in the water source being cut off by Zhang Gao, who led the army, and the Shu army was in chaos, defeated by the Wei army, and the street pavilion was lost. After this, Shu Han had no way to continue to digest long right, Zhuge Liang had no choice but to order a retreat, and the first Northern Expedition was fruitless.
After the street kiosk was lost, Zhuge Liang tearfully beheaded the horse to affirm the law. However, some people believe that although Ma Mo had issued a military order, coupled with his escape from the battlefield and was beheaded by Zhuge Liang, it was extremely difficult for Ma Mo to always hold the street pavilion with the strength of Ma Mo's troops at that time. After all, during Zhuge Liang's first Northern Expedition, he only had 80,000 troops in his hands, when the former army wei yan, Wu Yi and others led 30,000 to surround The cities of Jicheng and Shangyi, while Zhuge Liang led 30,000 Chinese troops to sit in Xixian and attack Qishan to ensure that the grain and grass from Hanzhong were not cut off, and the army sent to Ma Mo and Gao Xiang at that time was only about 20,000 people, and these 20,000 soldiers were also divided into two parts, one of which was led by Gao Xiang and sat in Lieliu City, and the other was led by Ma Mo and guarded the street pavilion.
After the Wei Ming Emperor Cao Rui learned that Zhuge Liang's actual purpose was to fight for Long right, he immediately sat in Chang'an and asked Zhang Gao to lead an army of 50,000 to the street pavilion. Although Zhang Hao only led a small number of elite troops to the street pavilion at the beginning, even if this part of the army was blocked by Ma Mo outside the street pavilion, then the Wei army arrived, with a force of about 10,000 troops, not necessarily able to hold the street pavilion all the time. What's more, if the Wei army wanted to retake Longyou, it had to conquer the street pavilion to march to the long right, so the street pavilion was bound to be attacked continuously. Since it was difficult to completely defend the street pavilion with Ma Mo's troops, and the Bao Street Pavilion was not lost, why did Zhuge Liang let Ma Mo set up a military order to guard the street pavilion?
In fact, Zhuge Liang also knew that with Ma Mo's troops, it was impossible to completely defend the street pavilion, so he did not plan to let Ma Mo completely guard the street kiosk at the beginning, he just wanted Ma Mo to drag out time. After all, for Zhuge Liang, the goal of his first Northern Expedition was not to hold the street pavilion, but to occupy long right, and to occupy long right, it was necessary to cut off long, that is, cut off long road, so that the reinforcements of the Wei army could not support long right from Guanzhong, and Zhuge Liang wanted to use this period of time to capture Qishan.
It should be known that Qishan and Xiangyang and Hefei became Cao Wei's "great defense of the country", and Guan Yu could not conquer Xiangfan even if he was wei zhen Huaxia, sun Quan repeatedly led 100,000 troops could not take Hefei, and Qishan's defensive ability was comparable to these two cities, which showed that it was difficult to conquer, and because of this, Zhuge Liang would personally lead an army to conquer Qishan. In fact, at the time of the Battle of Jieting, the Qishan defender Gao Gang was almost unable to withstand the strong pressure of the Han army, and he saw that the Wei army had not yet arrived, and Qishan was about to be conquered, so he already had plans to surrender at that time. That is to say, as long as Ma Mo could persist through Zhang Hao's first wave of offensives, Zhuge Liang would be able to conquer Qishan and lead the main army to the street pavilion to resist Cao Wei's reinforcements, Ma Mo would not have to be defeated and killed, and the First Northern Expedition could also be a complete victory. Unfortunately, Ma Mo's deployment errors caused the complete defeat of the First Northern Expedition.
The author believes that Zhuge Liang asked Ma Mo to guard the street pavilion, not to ask Ma Mo to stick to it, but to ask Ma Mo to hold on to time, but it is a pity that Ma Mo failed to complete the task given by Zhuge Liang.
