If Ma Su guards the street pavilion, will Zhuge Liang succeed in his first Northern Expedition?

If Ma Su had kept the street pavilion, Zhuge Liang's first Northern Expedition would not have been successful. Zhuge Liang went out of Qishan six times and made a northern expedition to Wei. Only the first time is the closest to victory, and there is no chance to win the final victory in the rest of the time. But even so, Zhuge Liang did not give up his attack on Wei, because he knew that there was a big gap between Shu and Wei. The longer the time, the stronger Wei is and the weaker Shu is. Only by seizing the opportunity to go straight to Huanglong can we ensure the existence of the Shu-Han regime. Zhuge Liang actually attacked our country with a lucky attitude, knowing that he could not fulfill his wish to unify the world in his lifetime.

Although Zhuge Liang led the first Northern Expedition, it was smooth in the early stage and won a staged victory. However, it is the national strength of Shu and Wei that determines the outcome of the war. At that time, Shu could only support Zhuge Liang to seize the region. If he keeps going, he will meet more fierce resistance. It is a question whether Zhuge Liang can persist until the end. At that time, the national strength of Wei was much stronger than that of Shu. As long as Wei defends blindly, Zhuge Liang has no choice but to take them down. So in the end, Zhuge Liang will definitely not win the final victory.

Zhuge Liang asked Ma Su to guard the street pavilion. In fact, it is a very puzzling thing. Although Ma Su is a little gifted, he has never had actual combat experience in leading troops to fight. It is not like Zhuge Liang's style to let such a person with no actual combat experience guard such an important place. If he sends a general with war experience to guard the street pavilion. It was entirely possible to hold this place, but Zhuge Liang failed to do so.

Ma Su and Zhao Kuo are the same kind of people, so they can only talk about it. But when you really get to the battlefield, you are useless and don't even understand the basic art of war.
