~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In February of the fifth year of Jian'an, Ma Han led a group of subordinates, Jia Xu, Guo Jia, Xun You, Xu You, Le Jin, Zhang Liao, Li Dian, Gao Shun, Yu Ban, Zhang He, etc., to gather in Yanzhou Juyeze to inspect the naval exercises.

This naval army is based on the 3,000 Danyang soldiers and 1,000 Shanyue soldiers rescued by Ma Han himself, and there are 2,000 Huai and Yangmen guests from the Mi brothers, plus nearly 1,000 Nanyang naval troops. Finally, thousands of sailors and boatmen were recruited from Xuzhou, Huaibei and other places. Form a 10,000-strong water army.

This naval army is just the main force of the Southern Expedition on Ma Hanming's face, in fact, his real naval force is the Bohai Navy. It's just that this sailor who is far away in Liaodong has never appeared in Jianghuai, and no one knows it at the time, which is his killer weapon.

Even so, the power of this on the surface is quite amazing. You must know that at this time, whether it is Jiangdong Sun Ce or Jiangxia Huangzu, these two powerful warlords south of the Yangtze River, their building boatmen, pawns, boatmen and other pure water army forces are less than 10,000. Only Liu Biao in Jingzhou, with more than 30,000 sailors, can be called the most powerful in the Han Dynasty.

Like Cao Cao in history, after unifying the north, Ma Han's next thing to do was to march south. As a "person who has come over" in history, Ma Han of course knew what the results of Cao Cao's southern expedition were, so in the months after pacifying the north, Ma Han repeatedly compared Cao Cao in another time and space with himself in this time and space, what are the advantages and disadvantages, and at the same time used war games to deduce the similarities and differences between the two time and space, and the battle situation. After several months of argumentation, the following results were obtained.

Cao Cao's southern expedition, Sun Liu united. The Great War of the North and South, with the Battle of Chibi as a turning point, Cao Cao's defeat was roughly in the following aspects:

First, the northern soldiers are not accustomed to water warfare. Giving up the saddle horse, fighting the boat, and competing with Wu Yue, this is a typical shortcoming, attacking the enemy's long. Cao Cao, who is a master of the art of war, will not fail to understand this truth, so the method he adopted is to use the surrendered Jingzhou naval army against the Wu army, but unfortunately he was wrong. Before the Battle of Chibi, Cao Cao commanded the Jingzhou naval army to fight the Wu army. As a result, the Jingzhou naval army was defeated. That's why Cao Cao asked for warships, but it was precisely because of this that he was attacked by the enemy, and in the final analysis, it was caused by the lack of naval forces.

In fact, before the southern expedition, Cao Cao dug a huge pond in Yecheng and poured water into it for Xuanwu Lake to train the naval army. It's just that the navy has grown from scratch to form combat effectiveness, and there are no years of work. After many actual battles, how can it really become an army? Therefore, Cao Cao's navy is just a group of water soldiers, not real building boat soldiers, which is the same as "horse infantry" and cavalry.

There's one more question here. The Cao army and the Jingzhou army together seem to have a lot of people and ships, but one side has just descended, the morale is hesitant, and the time is too short. Unable to get along with Cao Jun. As a result, instead of forming a joint force, the two forces not only failed to form a joint force, but instead restrained each other and dispersed their forces. The battle is twice as effective.

The second is epidemics. Cao Jun's southern expedition was in July, in the middle of summer, and it was the season of high incidence of infectious diseases. Cao Cao suffered a big loss in this regard, and before taking a battle, he first folded nearly half. Originally, Cao's army had nearly twice as many troops as the Sun-Liu coalition army, but it was tossed by the epidemic and lost its military advantage.

The third is that Ma Chao and Han Sui were in Kansai at the time, and they were troubled after the exercise. Before Xiahou Yuan pacified Guanxi, the Guanxi army had always been a threat to Cao Cao, not only thinning the strength of Cao Cao's southern expedition, but also causing the defeat of Chibi, he had to return to the court to sit in the center, for fear of being robbed by the Guanxi army.

In addition, there may be other four, five, or six, but they are beyond Ma Han's cognition, with his limited knowledge of the Three Kingdoms, combined with the information collected by Eagle Eye in Jingxiang and Jiangdong before, Ma Han can only summarize these few.

So, what about the horses of this plane?

The first is the water army. Ma Han established his own water army, the Bohai Navy, very early. This is not only a naval force that can brave the wind and waves, but also a prototype of a navy that can sail and fight in coastal waters. Not only that, but also established a sub-base and established the Yuzhou Mountain Army.

Since their establishment, these two navies have fought to exterminate pirates, and have also undertaken the important task of transporting troops and grain from Liaodong to Luoyang, thousands of miles away. These thousands of miles of transportation of money and grain are naturally indispensable to fight with bandits and lakes along the line, and have accumulated rich valuable experience in rivers, lakes and seas battles and long-distance transportation.

From the beginning, Ma Han set his sights on the sea, which Cao Cao, who didn't even pay attention to the rivers, was far behind. Moreover, at the beginning, Tao Qian was grateful for Ma Han's grace in saving Xuzhou and making a living for his two sons, leaving Ma Han a rich inheritance - 5,000 Danyang sailors and more than 200 ships.

This naval army, which is not weak, had no obvious effect when Ma Han was fighting for hegemony in the north in his early years, and was even forced to participate in the Battle of Surabaya by Yuan Shuxie, and was almost completely wiped out by Lu Bu. For this reason, Ma Han also went to Xuzhou in person, risked his life, fought with Lu Bu, and took this naval army away from the battlefield of life and death.

Because of this, Ma Han was grateful and loyal to the Danyang Navy. The hard work of the year is best rewarded today. This naval army has been completely attached to the Lord, and its loyalty may not be as good as the Dragon Wolf Army from Liaodong, but it is better than the new army of Luoyang.

The main battle force of the Danyang Water Army, more than 1,000 Shanyue soldiers, followed Ma Han and Chen Dao from the time of the Battle of Xiapi, fought in the south and the north, and from Huaibei to Luoyang, they had already integrated into the Dragon Wolf Army and became a force to be reckoned with.

This Danyang native, familiar with the Jianghuai water scenery, water combat power is the crown of the Three Kingdoms of the water army, is completely belonging to the horse, has a strong cohesion, can command freely. This point is by no means comparable to Cao Cao in history.

Second, about epidemics. Obviously, only the army infantry cavalry, not the navy, was really affected by the epidemic. In the southern expedition, the navy is the fist, and the army is the iron arm, and the two complement each other and are indispensable. Most of the dragon wolf army are northern soldiers, and there are also many soldiers from the extreme north, and the miasma of Jinghuai is indeed a big problem for them.

There are four ways to solve the problem: first, to successively send troops to Jianghuai, not tens of thousands of people at once, the more people, the greater the probability of epidemic outbreaks; the second is to postpone the time of the campaign to autumn and winter, and stagger the epidemic season as much as possible; the third is to carry out the popularization of health and epidemic prevention knowledge among the troops of the Southern Expedition; The fourth is to find good doctors and prevent them in advance.

Ma Han is not a doctor, but he still understands the basic knowledge of epidemic prevention in later generations, such as boiling water to drink, excrement must be buried, sprinkling quicklime in the barracks, and not wading in water during non-military operations. As for the good doctor who treats infectious diseases, Ma Han doesn't need to ask for talents, and directly appoints one person - Zhang Ji and Zhang Zhongjing.

Zhang Zhongjing, the first person in the history of traditional Chinese medicine to prevent and treat infectious diseases, was revered as a "medical saint" by later generations. This is a character written into primary and secondary school texts, Ma Han naturally knows, but he doesn't know that Zhang Zhongjing is actually a figure in the Three Kingdoms period at the end of the Han Dynasty, let alone that this person is under his nose.

Speaking of the process of Ma Han discovering Zhang Zhongjing, it is also an interesting story. It was the end of the fourth year of Jian'an, Ma Han had just returned from Yanzhou, and when he went to the court, he saw Xu Youwei with smoke, and when he asked, he learned that he had just sent a friend from the same county to Changsha to serve as the chief bookkeeper.

Ma Han was not interested in taking care of other people's private affairs, but just advised: "Don't drink alcohol before going to court, this matter is excusable, and the next one is not an example." ”

Although Xu You was crazy, he was quite jealous of this general who had cleaned him up and lost his temper, and hurriedly saluted to explain the reason: "I didn't want to drink, but when I went to Nanguan Pavilion, the three elders of Tingyi brought everyone to send them with newly brewed ale wine, and thanked Zhongjing Xian for saving his Tingyi father, so he had to toast, so he ......"

Treatment? Ma Han was slightly surprised: "Is this Changsha master a doctor?" ”

Xu You nodded: "Zhongjing has the ability to rejuvenate with wonderful hands, and he has also diagnosed and treated the Son of Heaven." ”

Ma Han has rarely stayed in Luoyang recently, and he is not very clear about some unimportant personnel changes in the imperial court, frowning and thinking hard: "Zhongjing...... This word sounds familiar, what is his name? ”

"Zhang Ji, Zhang Zhongjing."

It is said that Zhang Ji really doesn't know much, but Zhang Zhongjing ...... Ma Han didn't let Xu Yu go to court, and directly dragged him into his general's exclusive double-wheel carriage, and told him: "Hurry up and chase Zhang Zhongjing back for me!" Even if you chase you to Yique Pass, you have to chase people back! ”

Xu You was almost thrown into the car by Ma Han, dizzy, and said: "General, this, this, could it be that Zhongjing has offended......

Ma Han stretched out his palms and slapped the buttocks of the two horses, and rode the horse neighing forward, Ma Han stood under the gate and said loudly: "Find Zhang Zhongjing, tell him, you don't have to go to Changsha to be the chief bookkeeper, I want to get rid of him as the general shogunate." ”

The shogunate is not high, only 400 stones, but it is a popular position - the shogun shogunate Zhucao, but the people who meet with the generals from time to time to discuss matters are done well, and it is not difficult to reach a thousand stones or even two thousand stones in a year or two.

Xu You was surprised and delighted when he heard this, and he couldn't help but run out of the south gate with the carriage and horse.

In this way, Zhang Zhongjing became a member of the Mahan shogunate, nominally the chief of the council, and was actually in charge of the field medical battalion of the Dragon Wolf Army. Later, the officers and men of the Dragon Wolf Army called it a "medical order", and over time, the Dragon Wolf Army had a new position: a military medical order.

It can be said that the two biggest troubles encountered by Cao Cao are not troubles for Ma Han. As for the Kansai Army...... Ma Jiajun is a great scourge to Cao Cao, but he is the backer of Ma Han, which is even more incomparable.

It was precisely because of the analysis of his own advantages and sufficient preparation that Ma Han dared to decide to launch the southern expedition in the fifth year of Jian'an, eight years earlier than the battle of Chibi in history.

This year, Liu Biao is in his prime.

This year, Sun Ce is in full swing.

This year, Liu Bei was in full swing.

This year, Cao Cao Xiaoqiang made a comeback.

The so-called advantages have disadvantages, and the opponents faced by Ma Han were stronger than Cao Cao's back then; The situation is more difficult than the battle of Chibi - but what is there to fear? Life's challenges are everywhere. Fighting with the sky, the fun is endless; Fighting with people is endlessly fun; With the four most powerful cattle of the Three Kingdoms, they will hunt the Yangtze River, and they will have endless fun.
