Who led troops out of the meridian valley in history, and what was their end?

During Zhuge Liang's Northern Expedition, Wei Yan once put forward a clever plan, which was called "Woods' plan" in history. Following the story of Han Xin, he built a plank road in the Ming Dynasty and secretly crossed their positions. It's a pity that Zhuge Liang thought the plan was too dangerous and Shu Han couldn't stand too much damage, so he didn't use it. Then, from Wei Yan, who led the troops out of the meridian valley in history, what was their ending?

First of all, Cao Zhen, the general of Cao Wei, led his troops out of the Meridian Valley in the battle of cutting Shu, and wanted to join forces with Sima Yi, the viceroy, in Hanzhong. Unfortunately, shortly after he entered the valley, it began to rain continuously, and all the plank roads and bridges along the way were washed away by the flood. Coupled with the steep roads in the valley, it is even more difficult to move, and we have to withdraw our troops. Because of the weather, Cao Zhen didn't leave the valley and didn't fight with the enemy, so this campaign can't reflect whether the Meridian Valley can work.

Secondly, Sima Xun of the Eastern Jin Dynasty (Huan Wen's subordinate) led his troops before the surprise attack in the Meridian Valley. As a result, Qian Xiong, the former prime minister of Qin Dynasty, was ambushed by thousands of troops and died. The Jin army was badly weakened, so it withdrew reluctantly, and Huan Wen's Northern Expedition plan failed.

Finally, Gao Yingxiang suffered the worst defeat in the late Ming Dynasty. At that time, he was going from Hanzhong to Xi 'an, and the route to leave the army was still the Meridian Valley. However, unlike Cao Zhen and Sima Xun, Gao Yingxiang overcame the steep valley and led the army through the valley within 15 days. Unfortunately, as soon as he arrived at Taniguchi, he was ambushed by more than 10,000 soldiers and horses from Sun Chuanting. After several days of fierce fighting, Gao Yingxiang's army was completely annihilated, and he was executed this year.

From this point of view, it is understandable that Zhuge Liang did not accept Wei's plan during the Three Kingdoms period. After all, this plan is too dangerous, and Shu Han was just defeated by Yiling at that time, and he could not afford too much loss.

Generally speaking, Woods Valley is steep and influenced by many factors. For example, Cao Zhen has been out of the valley because of the heavy rain. If there is an ambush, the people out of the valley are quite passive and it is difficult to get away with it. However, if we can get out of the trough smoothly, the effect is absolutely undeniable. Soldiers are familiar with it, and the work of raiders is twice as strong as that of soldiers. If Wei Yan can get out of the valley smoothly according to his plan, he can take Tongguan area, which is difficult to capture by heavy troops, by surprise.
