The country has only been established for more than 20 years, and the Jin army's combat effectiveness has deteriorated severely, as a minority dynasty that has conquered the Central Plains and destroyed the first power in East Asia, this terrible phenomenon has aroused deep concern among the senior generals of the Mesozoic Dynasty headed by Wushu, and he began to worry that the Jin Dynasty will repeat the old path of other dynasties in history, like the Qin and Sui dynasties, and will die in two lifetimes after being strong for a while, and their life span is very short.

After repeated military defeats, the decline of the Jin State was already apparent, and the Wushu worried that the strength of the Jin State was likely to be just a flash in the pan, and if effective measures were not taken in time, then the day when the Jin State was destroyed by the Song Dynasty was just around the corner. Of course, he didn't want to follow the old path of Qin and Sui, as a strong general who had been in the army since childhood, he certainly knew that the best way to improve his military strength was to fight on the battlefield, the watering of blood and the pleasure of beheading the enemy under the horse, and taking other people's property and women into his own pocket.

Based on this consideration, Wushu decided to take advantage of the fact that the old guys who can fight well in the Jin Kingdom have not yet died, and the courage of the Jurchen soldiers has not completely degraded, so as to restart the reactionary war and build an invincible army. As for whether this kind of attack can achieve its goal, only genius knows, but at least it can obtain more space for the survival and development of the Jin State, so as to maintain the strength of the Jin State for a longer time.

Among the neighbors of the Jin State, there are still three enemies who can qualify as the Jin State: the first is the sworn enemy of the Great Song Dynasty, the two countries from the alliance to the collapse of the two countries in only a few years, they captured its capital, kidnapped the emperor of the Song Dynasty, and almost destroyed them, it can be said that the two countries are an endless situation, and the paper peace agreement has never taken effect. But now the Great Song Dynasty has risen again after Zhao Er's operation. In turn, he attacked them, and the vultures knew that with their current strength, they were not sure of victory;

the second is the Western Liao State established by the Khitan remnant Yelu Dashi; The hatred between the Jin Kingdom and them was several times deeper than that of the Song Dynasty. After all, you have removed people from the earth and occupied their industries. And Yelu Dashi is still thinking about returning to the country. But the problem is that the two countries are thousands of miles apart, and the cost of launching an expedition is too great, and the current national strength of the Jin country is somewhat unbearable.

Wushu has always wanted to bring trouble to the south and make them enemies with the Great Song Dynasty, but Zhao Er was very shrewd and stopped at Linhuang Mansion, and has always refused to use troops to Mobei, but left a corridor connecting the two countries of Liao and Jin, so that they can use troops conveniently. Of course, Wushu refused to fall for Zhao Er. fell into his trick of competing with the fisherman for profit, so now he can't easily use troops to Xiliao.

The third is the undeniable Mengwu tribe of the buns, these people have no strength, but they are too annoying, there is no fixed base for life, they live a life of grazing everywhere, where there is water and grass, they will set up tents to settle down, and then change places to graze and live. Militarily, it is dominated by cavalry. It is a guerrilla war, and if you have fought it, you will grab it, and if you can't fight it, you will run, anyway, the territory of Mobei is large. If you have the ability, you can chase it to the North Pole.

The current situation is that the Mughal tribe took refuge in the Great Song Dynasty and lived in a protected area designated by it, although this protected area occupied the territory of the Jin Kingdom. But the Jin State did not dare to trespass now to avoid conflict with the Song. However, the Mengwu tribe continued to annex other tribes with the support of the Great Song Dynasty, and became bigger and bigger, and it was even more difficult to provoke, and became a tiger raised by the Great Song Dynasty. Squatting in front of their house.

Therefore, the cost of fighting the Mengwu is also not small, if it is not done well, it will become a protracted war, and more importantly, those soil buns are too poor, and now they have to rely on asking for food to live, even if they squeeze out their bones, they really don't have much oil and water, and they have to risk a large-scale conflict with the Song army, which is not in line with the principle of using troops to train the army and improve the economic situation!

After some selection, Wushu set the target on Goryeo, it is adjacent to the Jin State, and the military is weak, it was conquered by the Jin State, although it is not as rich as the Great Song Dynasty, but it is also rich in products, just use it to train the army and loot by the way. And he used to be a vassal to Jin, but two years ago he switched to the Song Dynasty, not only refused to pay tribute to Jin, but also cut off all contacts, completely fell to the Song Dynasty, in the name of punishing the betrayal of the subject country to send troops is also famous......

In August of the second year of Jin Tianjun, Wan Yan officially issued an edict to the Marshal Mansion of Jin Guodu to send troops to Goryeo to crusade against the rebellion. Wushu also got a great opportunity to go to the battlefield and show his talents, but the problem of the lack of talents among the generals of the Jin Kingdom was once again placed in front of him. After some picking, Wushu chose his partner in the previous Song Dynasty to serve as the right supervisor of the marshal, and took the naval army to control the Diagonal Ali as the deputy marshal, raising a total of 100,000 troops, known as 200,000, and sending troops to Goryeo.

It is not a secret that Goryeo declared itself a vassal to the Song Dynasty and leased the ports of Sumi and Busan to the Song Dynasty as a port for supplies and repairs of ships. Wushu is not a fool, and he also included the Song army's possible plan to send troops.

Song and Goryeo have no land border, and Goryeo exchanges are by sea, after Song learned the news of the Jin invasion of Goryeo, Zhao Er will not care about what Zhao Er did in the past, he will inevitably send troops to intervene, reinforcements from the sea is the only option, and now the trade wind is not in the right direction, and the Song army's naval army can only come in a roundabout way, which leaves him plenty of time to use troops in Goryeo. Another reason is that now the Great Song Dynasty has sent a naval army to be stationed on Shenmi Island, and it is not difficult to know the Wushu, and at the same time as sending troops to Goryeo, it is necessary to pull out this stronghold of the Song army, so that its reinforcements will lose their foothold and annihilate the enemy at sea.

The Great Song Dynasty naval army is strong, and has been blockading the coast of the Jin Kingdom to prevent its trade, and everyone in the world knows that the battle plan of Wushu seems to have no possibility of realizing it at all, but now Wushu is so confident, because he also has a strong force on the water, and he can't beat it on land, maybe he can get some face back on the water......

And what is the level of the Jin country's water army?

Jurchen rises in the northeast between the white mountains and black waters, there are many rivers in the territory and close to the Bohai Sea and the Sea of Japan, when Wanyan Agu fought against Liao, the Jurchen social and economic production is mainly fishing and hunting, and there is a certain amount of agriculture, boats are an important means of production, life and transportation for the Jurchens, but the level of shipbuilding is very low, can only 'cut wood for the boat', make canoes, this environment and life characteristics determine that there are a certain number of Jurchen people who are more familiar with boats, they are the earliest members of the Jinshui Army.

In the subsequent war of tribal unification, the Jurchen tribe inevitably had conflicts with Liao and Goryeo, which then turned into fierce military conflicts. The war with Liao was mainly fought on land, but there were also naval battles and island battles on a certain scale in the coastal waters near the Liaodong Peninsula. Goryeo and Kim were connected, and the two sides had more contacts and exchanges, and the two sides also fought at sea. In the early days, the Golden Water Army also appeared in battle and accumulated some combat experience.

Generally speaking, the Jin State Navy at this time was small in scale, and its members were mainly Jurchens. There are only more than 20 boats participating in a war, or even more than 30 people, and the boundaries between the navy and the army are not clear, and they are not specialized in water warfare, and they also participate in land warfare, and the tasks they undertake are not single.

It is only because these soldiers in the Jin army are familiar with the characteristics of water warfare and only operate boats to participate in battles when needed, and in peacetime the navy is only a part of the infantry cavalry army that also has the ability to fight water warfare. The Jinshui Army's combat mode of taking into account both land and water determined that the scale of the water warfare in which it participated was relatively small, and the level of water warfare skills was not high, and it could only basically meet the needs of the war situation at that time.

However, after the founding of the Jin State, the transit was vast and the coastline was long, and the main enemy, the Song Dynasty, was a country with strong traditional naval forces, and often attacked the coastal areas of the Jin State by seaway. In particular, after Zhao Ta ascended the throne, he vigorously developed the naval army, and used the naval army to successfully carry out the landing operation behind the enemy line in Yingzhou, which caught him off guard, and then sent the naval army to shell the coastal prefectures and counties and launched a landing operation, which not only restrained a large number of their troops, but also caused great panic among the people and severely damaged their morale. Later, they blockaded the shipping lanes with naval armies and cut off trade, which dealt a heavy blow to their economy.

However, the Jin navy was helpless in the face of the Song army's blows and attacks, and was sunk in battle, so it could only retreat in Hong Kong to avoid the battle. In the face of such attacks by the enemy, strengthening coastal defense has become very important to maintain the security and social stability of the country. To this end, Marshal Jin's office ordered the construction of walled cities on key coastal areas, sent garrisons to defend against attacks from the sea, and also began to develop a naval army.

The Jin State recruited people of various ethnic groups who were familiar with water and proficient in shipbuilding, cut down trees to build ships, and expanded the naval army. So far, the Jin Navy has experienced a process from small to large, from weak to strong, and the ships equipped by the Navy have also transitioned from the initial plundering to self-construction, and the quality of the ships has also been greatly improved.

However, the Khitan and Xi people under the rule of the Jin State belonged to the nomadic people and were not skilled in water, while the Jurchen, Han, Bohai and other ethnic groups had more contact with and used boats, but because the Jurchen people's ability to sail was limited, compared with other ethnic groups, the Han people had a long history and rich experience in using boats to navigate inland rivers and seas, and were better at boating and proficient in water warfare, so those Han people who were taken captive to the Jin State became the main force of the Jin Water Army.

However, this does not mean that the Jurchens are relieved to hand over the command of the Han people, as the rulers of a country, they are also in a dominant position in the navy, and most of the high-level generals are Jurchens, and a small number of members of the Khitan, Bohai and other ethnic groups are guarded against the soldiers of the Han and other ethnic groups, but this method also discourages their enthusiasm and restricts the improvement of their own combat effectiveness......
