The seventh offensive line that Liu Yin decided to use was to start from Nanzhong, attack Jiaozhou, and end up the two states of Jiaoguang that had always been called the great rear by Wu, and then go north in a roundabout way to attack Jingzhou. Pen & Fun & Pavilion www.biquge.info

The most important reason is that the road is far away, and the logistics supply is extremely difficult.

However, at this time, Liu Yin wanted to march from Nanzhong, or have something to rely on, when Shu Han was in danger, hundreds of thousands of people moved into Nanzhong with the imperial court, and later Yizhou was recovered, and the imperial court moved back to Shuzhong, not all the people who moved south followed back to Shu, and a large proportion of the people stayed in Nanzhong. They had been living in Nanzhong for many years and were used to life there, and many volunteered to stay.

Due to the southward migration of a large number of Han people, a lot of land has been developed and utilized, Nanzhong is no longer the kind of wild elephant when Zhuge Liang conquered the south, the land here is fertile, the climate is pleasant, the products are abundant, under the hard work of the people who moved south, Nanzhong has long been slow to change the old appearance of the new look.

When the Ji Han court favored Nanzhong, all its expenses came from the local area of Nanzhong, and the taxes of the counties in Nanzhong could basically meet the expenses of this small court, and later the Ji Han court moved away from Nanzhong, and the taxes in Nanzhong had a large surplus. After several years of accumulation, the grain stored in the official warehouse of Wei County is already a very large amount.

Liu Yin also found that a large amount of grain and grass was stored in Nanzhong after reading the information of grain in various places, which undoubtedly provided a material guarantee for Liu Yin's roundabout operation.

The most difficult thing in this kind of large-scale in-depth and large-scale roundabout operation is the supply of grain and grass, and after solving this difficulty, the rest of the things can no longer be called difficult.

According to the information available now, there are not many garrisons in Jiaozhou and Guangzhou in Wu, which means that Wu has not paid attention to this defense line in Jiaozhou and Guangzhou, and if the Han army sends a light cavalry force, it can easily sweep through the Jiaoguang counties.

Why did he send cavalry, it was because if Liu Yin transferred troops from the Central Plains at this moment, he would return to Nanzhong, capture Jiaozhou Guangzhou, and then return to Jingzhou, so a march spanning seven or eight thousand miles, if it is infantry, it will take at least half a year, which is not counting the war, once the war is stalemate, if the siege is not overcome, it will drag on longer.

Therefore, Liu Yin deliberately arranged light cavalry troops, and with the speed of cavalry, the time for marching could be greatly shortened, and the above itinerary could be completed in two months at most.

Liu Yin, the seventh road man, selected the Tiger Cavalry Army and the White Tiger Army, which had the most combat experience, with a total of 30,000 soldiers and horses, and half of the firearms battalion would also be allocated to accompany the expedition.

The cavalry is invincible in the field, but siege operations are always a weakness, if the Wu soldiers of Jiaozhou retreat in the city pass and refuse to fight, no matter how elite the cavalry is, I am afraid that there is nothing to be done, with the assistance of the firearms battalion, it will be twice the result with half the effort, any strong city, I am afraid it will not be able to block the attack of firearms, this combination of cavalry and firearms, sweeping the world is no problem.

As for the commander-in-chief, Liu Yin did not arrange for anyone else, but he personally led the team.

As soon as the decision came out, all the generals objected, and they all thought that Liu Yin was the governor of the capital, and it was enough to strategize, so why do you need to do such a hard expedition, just send a partial general to lead the army.

This expedition to Jiaozhou, the difficulty is not in how to conquer the city, but in the roundabout march, because the Han army in the Jiaozhou area has not been involved at all, and the geographical conditions and climatic conditions over there are completely unknown, except for Liu Yin's own leadership, he really can't think of any suitable person to take on this position.

Liu Yin smiled and said to the generals: "You all think that this is a partial division all the way, it is insignificant and insignificant, in fact, this seventh way of men and horses is the core of the attack on Wu State, this partial division is used well, and it can become a surprise soldier who smashes the heart of the enemy." ”

In fact, over the years, these confidants who have followed Liu Yin for many years have a very deep understanding of Liu Yin, and it is difficult to make changes easily in everything that Liu Yin decides.

Before leaving, Liu Yin temporarily appointed Fu Yi as the commander-in-chief of the six-way expedition to Wu, and all the armies were ready to go on the expedition, entered the first-level state of combat readiness, and waited for the order to go out.

Then, Liu Yin led the Tiger Cavalry White Tiger Army, left Luoyang, and marched to Nanzhong.

Because it was a light horse, it only took more than ten days for Liu Yin to return to Chengdu, but Liu Yin did not make the slightest stop in Chengdu, and went straight south to Nanzhong.

When the Northern Expedition was waved, leaving Nanzhong, it has been fifteen years, Nanzhong is just a hurried passer-by for Liu Yin, Nanzhong was still a barren scene, and now in Nanzhong, I found that there are thousands of acres of fertile land, a prosperous and rich scene.

This is undoubtedly the great change brought about by the migration 15 years ago, the influx of hundreds of thousands of Han people, not only brought a stable farming population to Nanzhong, but also brought advanced farming technology.

Liu Yin couldn't help but sigh and sigh, he couldn't plant flowers intentionally, and he didn't intend to plant willows and willows.

Zhang Qin, the Taishou of Jianning at that time, had already received an order from above and personally went out of the city to welcome King Yong.

When Liu Yin came to Wei County, he was most concerned about the storage situation of the official warehouse in Wei County, and the grain and grass storage here would be the key to the success or failure of Liu Yin's expedition to Wu.

Zhang Qin naturally knew Liu Yin's purpose, and he had already prepared the account book of the granary for Liu Yin to check.

After Liu Yin read it, he nodded, Zhang Qin's account book was completely consistent with the high record of the imperial court, and there was no leakage, Liu Yin said that he was very satisfied, and immediately let people accept this batch of grain and grass.

The purpose of this trip was to arrive in Nanzhong as soon as possible, and his biggest reliance on attacking Jiaozhou was this batch of grain and grass.
