In the twenty-seventh year of Yuan Jia (450 AD, the eleventh year of the Taiping Zhenjun of the Northern Wei Dynasty), on the afternoon of December Geng, after bypassing a series of important towns such as Pengcheng and Xuyi, Tuoba Tao led his army to Guabu Mountain on the north bank of the Yangtze River, and then began to cut down reeds and trees, preparing to build small raft ships, claiming to cross the Yangtze River south.

This caused Jiankang City to fall into a panic, and the people in the city had even packed their luggage and were ready to flee with their burdens on their shoulders. Liu Yilong ordered martial law to begin inside and outside Jiankang, and at the same time ordered all Zhuang Ding and his sons and sons below the prince in Danyang to join the army. Then Liu Yilong ordered the leading general Liu Zunkao and others to lead their troops to guard the crossings and dangerous areas along the river, only to see that a large number of ships were lined up on the river, and the coast was interconnected, from quarry rock to Jiyang, up to six or seven hundred miles.
However, Liu Yilong believed that this was not safe, so he ordered the crown prince Liu Shao to lead the army to guard the stone and command the water army with full authority. Danyang Yin Xu Zhanzhi was ordered to guard the cangcheng city to which the stone belonged. The official Shangshu Jiang Zhan also served as the leader, and the military deployment was all decided by him alone.
Even though corresponding arrangements were made, when Liu Yilong landed in Stone City, he still couldn't help but look worried and turned back to Jiang Zhan: "The plan of the Northern Expedition, there are fewer people in the same discussion." Today,the people of the people are complaining, and they must not be ashamed, and the worries of the doctors are also wronged. Only then did Liu Yilong regret for hastily launching the Northern Expedition, and then the most tearful and laughing scene appeared, Liu Yilong sighed: "If Tan Dao Ji is here, will Huma be here!" "Let's not say who killed Tan Daoji, before the Northern Expedition, Liu Yilong was still accusing Tan Daoji of raising Kou's own funds, and now he is remembering Tan Daoji, is it not Liu Yilong himself who destroyed the Great Wall?"
After sighing, Liu Yilong climbed Mofu Mountain again to observe the situation. At this time, he opened his mind again, and issued an edict offering a reward for the purchase of Tuoba Tao and the heads of his kings and princes, promising that if anyone succeeded, he would be knighted and rewarded with gold and silver. At the same time, Liu Yilong also sent people to drop poisonous wine in the empty deserted village river in an attempt to poison the Northern Wei generals, but the result was naturally useless.
Because Tuoba Tao did not drink the water south of the Yellow River at all, he ordered people to follow him with camels to carry the water north of the Yellow River. At this time, Tuoba Tao also ordered the excavation of Guabu Mountain, the construction of a winding mountain road, and the installation of a felt hall on the mountain. But unexpectedly, Tuoba Tao sent someone to give Liu Yilong camels, horses and other gifts, asking for reconciliation and requesting marriage with the Liu Song royal family.
This sudden news surprised Liu Yilong, and after relieving himself, Liu Yilong sent Tian Qi to give them to Tuoba Tao with rare fruits and discuss specific matters. After Tuoba Tao got the yellow orange sent by Liu Song, he took it and ate it, and drank it bitterly. This frightened Tuoba Tao's attendants, who feared that Liu Song would be poisoned.
Tuoba Tao did not answer this, but raised his hand, pointed to the sky, and then called his grandson over to show Tian Qi and said: "I have come here from afar, not for the sake of merit, but for the sake of the people, and I really want to continue to serve the people and marry and help forever." If Song can take this grandson as a female wife, I will take my female wife, The King of Wuling, and from now on the horse will no longer look south. ”
It can be said that the conditions set by Tuoba Tao are not harsh, and Tian Qi returned to Jiankang to report the news to Liu Yilong. Liu Yilong then summoned the crown prince Liu Shao and his ministers to come to discuss, and everyone agreed that the marriage of Northern Wei should be agreed, but Jiang Zhan stood up against it, believing that "Rong Di has no relatives, and Xu Zhi is useless." ”
This made Liu Shao very angry, and he thought that Jiang Zhan's actions were disregarding the safety of Liu Yigong, Liu Jun, and others who were still in Jiangbei. But Jiang Zhan was still unmoved, so after everyone had finished deliberating, Liu Shao instructed his left and right attendants to push Jiang Zhan, and Jiang Zhan was almost knocked unconscious. Liu Shao was still angry, and then he went to Liu Yilong, demanding that Jiang Zhanzhi and Xu Zhanzhi be held accountable for the defeat of the Northern Expedition and that they beheaded. Of course, Liu Yilong would not agree, and he took the responsibility on his own head. Tuoba Tao's proposed peace and pro-family agreement also failed in the internal quarrels within the Liu Song court.
However, the fact that he was not able to make him not seem to be more angry did not seem to make Tuoba Tao more angry, and on the first day of the first month of the twenty-eighth year of Yuan Jia (451 AD, the twelfth year of the Northern Wei Taiping Zhenjun), Tuoba Tao, who was in a good mood, gathered all the officials on Guabu Mountain and began to reward them according to the size of their merits. Subsequently, a beacon was lit along the north bank of the Yangtze River, and after plundering the residents of the garrison and burning the houses of the common people, he led the army to the north.
What's going on? Tuoba Tao is only separated from Jiankang by a Yangtze River! In fact, it is not that Tuoba Tao does not want to take Jiankang, but at present, Northern Wei does not have a strong enough water army, and this is Liu Song's strength. Secondly, the soldiers of the Northern Wei Dynasty did not adapt to the climate in the south, and soldiers continued to fall ill, and the army began to break out of the plague. Moreover, after a long period of conquest, the Northern Wei army was also exhausted. In the end, the Liu Song army north of the Yangtze River had not been completely eradicated, and if they attacked from behind, the consequences would be unimaginable. So Tuoba Tao ordered that he should receive it when he saw it was good, and led his army back.
