Kublai Khan's war to destroy the Song Dynasty went smoothly and was a classic. However, few people knew that the proposer of this plan was not the Mongols, the resourceful and brave Boyan, nor the brave A Shu, nor the general Kublai Khan, but a Han man whose name was Guo Kan.

In history, Guo Kan died of illness during the first stage of the war to destroy the Song Dynasty, that is, during the attack on Xiangfan. Because the proposer of his plan did not participate in the specific implementation of the plan, Boyan and A Shu became executors, and became famous for their great success. The proposer of Guo Kan's plan was not known, and only those who are familiar with the history of the Yuan Dynasty knew about it.

When Li Jun got the news that Guo Kan was still alive in the world, his first reaction was that history was outrageously confused, and the history that had happened did not progress as it had happened. "Maybe history can be rewritten, and the tragedy of the demise of the Southern Song Dynasty can be avoided." Li Jun thought so.

The second reaction was that Li Jun felt that he was too big. Boyan and A Shu were not vegetarians, let alone Kublai Khan, who was a rough man, and if he had a good fortune, he would not be able to do so. If he had a Guo Kan, who was the first counselor of Kublai Khan, Li Jun would not be able to do so even if he had no big head.

Guo Kan, whose courtesy name was Zhonghe, was a legendary figure in Chinese history. His ancestors were Guo Ziyi, the famous general of the Tang Dynasty who suppressed the "Anshi Rebellion", and Guo Kan was the fifty grandson of Guo Ziyi. As a famous general, he was good at fighting. As a strategist, he was resourceful and was no problem to plan for thousands of miles. He was also a genius strategist who could look at the big picture and control the overall situation. He planned to destroy the Song Dynasty for Kublai Khan.

Since his grandfather Guo Baoyu has been an official in Mongolia. He is good at fighting and is very favored by Genghis Khan. His father is also good at fighting and has achieved fame. However, he is even more extraordinary. He is better than others when he is young. He is generous and generous, seven feet long, and has awesome power. He follows Hulagu to participate in the third Mongolian expedition, conquered the Middle East, led his army to the Mediterranean, captured a large area of ​​land but never suffered a defeat. He was shocked by a local monarch.

In Chinese history, only Guo Kan led his troops to the Mediterranean.

Guo Kan is not only a famous general who can fight, but also a strategist who can resolve doubts and make strange plans. His strange plans are extremely peerless and deeply appreciated by Kublai Khan. The policy of capturing Xiangfan was initiated by Guo Kan. He told Kublin: "The Song Dynasty lived in the southeast, with the land of Wu and Yue as its foundation. His key point was Jingxiang. At present, we should seize Xiangfan first. Xiangfan. In the Song Dynasty, Yangzhou and Hefei were just a small place. They were ignored. The army rushed directly to Lin'an with lightning speed. As long as Lin'an is taken down, the Song Dynasty would no longer exist, and the Jianghuai and Bashu land would be destroyed without attacking."

Destroying the Southern Song Dynasty and unifying China has always been the wish of several generations of Mongolian emperors. However, because the soldiers and civilians of the Southern Song Dynasty rose up to resist, Mongolia had a strong military force, and the Southern Song Dynasty was at peace, with powerful ministers in power, and weak ministers, Mongolia still could not do it. Kublai Khan, the brother of Mongol, summed up the experience and lessons of his predecessors. Given that Mongolia did not have a strong naval army and was difficult to break through the Yangtze River defense line, he decided to change the direction of his strategic offensive, first attacked Bashu Dali, and carried out a large roundabout and encirclement of the Southern Song Dynasty from the side. After more than ten years of hard work, Mongolia finally occupied most of Bashu and Dali, and the sword had been aimed at the back of the Southern Song Dynasty.

The strategic policy proposed by Guo Kan is very different from the legacy of Mengge. It requires the central government to make a breakthrough and send some troops to restrain the forces in the Jianghuai, Yanglu, Bashu, and Shu. The main force is directly attacking Lin'an and destroying the political and economic center of the Southern Song Dynasty. As the saying goes, "Destroy the strength, take the soul, fight the dragon in the wild, and the way is poor."

Kublai Khan's talent was very good at judging the situation and happily adopted this suggestion.

Li Jun knew the pros and cons of this plan well. The advantage was that the Mongols were fully utilized to give full play to their advantages of being good at riding and shooting, having many cavalry, being good at field battles, and carrying out rapid advances. They could take down Lin'an in one fell swoop without the Southern Song Dynasty responding and destroying the court of the Southern Song Dynasty.

The disadvantages of this plan are also very obvious. They are too fast to advance, and the traffic lines are too long, making it difficult to replenish supplies. In addition, Kublai Khan issued a ban to treat the people of Jiangnan well, and the supply of the Boyan army cannot be obtained through plunder, so the replenishment becomes a big problem. If an accident occurs, for example, the Southern Song Dynasty did not have the courage and determination to resist as expected, but instead fought back and resisted to the end, the situation of the war would change, and the outcome of the war would be expected.

If the Southern Song Dynasty was more smart and carried out a strong wall and clearing the country, even if Boyan ignored Kublai Khan's ban, he would not be able to provide local supply. The large amount of supply could only be transported in the rear, and the long transportation line and unstable rear would become fatal injuries. In history, Boyan and A Shu had worked hard to repair the shortcomings of this plan, and spent time to capture Yingzhou and Han River basins, so there was a good rear supply base.

For some reason, when history happened again, Boyan did not capture Yingzhou and Han River Basin, but pushed forward with all his might and went straight to Lin'an. This made his rear unstable. If he dragged Boyan's army to Lin'an and then used a knife to his rear, the fate of Boyan's army would be very worrying.

After learning the news, Li Jun said excitedly: "God helps me." It was precisely because of this that Li Jun made up his mind to send troops to the lost territory in Jiangnan to carry out guerrilla warfare, and cooperated with the frontal battlefield in Lin'an to turn the entire Jiangnan land into a cage, and Boyan was the tiger locked in the cage.

"Let the vast majority of people participate in guerrilla wars, and do not make special contributions. We must establish good military-civilian relations and treat the people as your relatives. The people are your elders and your brothers and sisters. If there are people who abuse the people, I will destroy his nine clans." Finally, Li Jun issued a strict order majestic order.

Li Jun was very clear about the characteristics of guerrilla warfare. Without the participation of the general public, it was like a castle in the air. Therefore, harmonious military-civilian relations would be the key to the success or failure of guerrilla warfare, so he had to issue this strict order.

A very prominent feature of guerrilla warfare is that it is very fast to pull the team, which is unbelievable. As long as the seeds are sown, there will be a large number of teams soon. Governments of all ages did not know the benefits of guerrilla warfare, but did not dare to adopt them in the distance behind enemy lines. The reason is that this force is too large and difficult to control. If someone has a second heart, the consequences will be unimaginable.

Li Jun doesn’t have to worry about this, because he has valuable experience as a great leader to learn from, so he doesn’t have to worry about losing control at all.

There is another advantage of guerrilla warfare, which is welcomed by any government, which is to save money. You can get a huge army without spending a penny. Soldiers are the people, and the people are the soldiers. It can also be said that half of the soldiers and half-people. Once attacked by the enemy, who else can you expect besides protecting yourself? Just shout: We support you spiritually and be with you spiritually, and you can achieve great benefits. Li Jun, who has an empty treasury, doesn’t have to worry about military spending at all.

Li Jun clapped his hands, and the two soldiers came in with a thick stack of printed materials and gave each person a copy to the audience. They picked it up and looked at it, which contained the six words "Guerrilla Strike Manual" printed on it.

"My lecture is over. Whether you are qualified students will be verified based on your military achievements. Those who pass will be given a diploma." Li Jun made a summary speech.

Li Jun fulfilled this promise and issued them a new copy of the "Graduation Certificate of the Royal Martial Arts Hall of the Great Song Dynasty" after the war. This training made Li Jun realize a problem, that is, it was urgent to create a military academy guided by advanced military theory. The place where this training was renamed "Graduation Hall" and the "Graduation Royal Martial Arts Hall of the Great Song Dynasty". Based on this, a series of regular military academies involving various military groups have been gradually created, and many generals who can conquer and fight well have been trained.
