In recent years, the Jin State was deeply affected by the Song Dynasty naval army, and they did not dare to leave the port with few small soldiers, and they did not dare to go overseas to fish with fishing boats, let alone merchant ships, so they began to develop the naval army after the Wushu mastered the military power, hoping to defeat the Song Dynasty naval army one day, so they began to form a professional naval army, divided it from the horse infantry army, and appointed the Jurchen general who was good at water warfare, Xianmao Ali, as the commander, and vigorously recruited the people of all ethnic groups who were proficient in boat manipulation and turrets to expand the naval army.

In order to avoid being detected by the Song Dynasty, the naval army was secretly developed, training troops in inland rivers and offshore waters, and no one knew its details in the boudoir. After several years of preparation, the Jin naval army has more than 700 warships of all kinds, sailors and soldiers reached 50,000 people, it can be said that even compared with the previous dynasties, it is an unprecedented fleet of scale, which is an attempt by Wushu to break the gap in military strength between Jin and Song, and it is also an inevitable choice to break through the Song Dynasty's blockade of the Jin sea trade routes.

After deciding to attack Goryeo, Wushu ordered the navy to dispatch to cooperate with the battle, and while launching an attack by land, he used the navy to descend the Apju River and land behind Goryeo by sea to respond to the land army. This is because after the founding of the country, Goryeo also faced the invasion of various powerful countries from time to time, deployed heavy troops on the border, and built fortified cities, if it could not be captured quickly, the arrival of Goryeo reinforcements or the help of the Song army would lead to a failure.

After the first conquest of Goryeo by the Liao State, Goryeo was defeated and forced to pay tribute to the Liao and cut off diplomatic relations with the Song, and the Liao gave Goryeo "hundreds of miles east of the Yalu River". Goryeo led troops to expel the Jurchens and built six cities: Xinghua, Tiezhou, Tongzhou, Longzhou, Guizhou, and Guozhou, and the territory of Goryeo has expanded to the area of the Yalu River. And build the Great Wall between the south of Xianxing and the north of Yongxing, and reach the capital of Lianpu. And build Dingzhou, Xuande, Yuanxing three passes. Since then, the Liao Kingdom and the northeastern part of Goryeo have been bounded by the Great Wall and Sanguan along this line. Pushing the border between Goryeo and Liao from the Daedong River to the Cheongchon River; At the same time, he actively crusaded against the Jurchens living along the Yalu River. Encroaching on the Jurchen homeland.

In order to defend against the Liao State, Goryeo established the Guangjun Division, which was organized into 300,000 Guangjun. At the same time, the ruler of the country, Wang Jian, adopted a strategy of immigration to Sibian and moved a large number of people from the south to the north of the peninsula, which strengthened the border defense of northern Goryeo and greatly expanded the land area. By the end of his reign, the northern border of Goryeo had reached as far as Yongxing in present-day South Hamgyeong Province and the southern bank of the Cheongcheon River. The territory greatly exceeded that of Silla.

After that, Goryeo took advantage of the endless war between Jin and Liao, and when he had no time to take care of it, he twice raised troops to invade the Jurchen of the Liao State and forcibly built nine cities, and was later defeated by the Jurchens and recovered the Lazydian, but Goryeo did not give up expansion, and then took advantage of the Jin and Song wars, and the Jin regime changed, occupying the former Liao town of Baozhou on the east bank of the Yalu River. After Goryeo declared himself a vassal to Song, of course, he was more wary of Kim's punishment and sent heavy troops to defend it. The permission for Song to lease Mi Island was also intended to strengthen ties between the two countries and deter the Jin State.

The Wushu navy sent a detour back to Baoju, which was heavily guarded by Goryeo, and landed on its back, which would inevitably cause it to panic and withdraw its troops in order not to be completely annihilated, and the land army could take advantage of the situation and go straight to Goryeo's Xijing. At the same time, the naval army can also pull out the base of the Song army on Shenmi Island by the way, which can be described as a plan to kill two birds with one stone, so the Jin army and the naval army came out in this operation. In order to ensure victory in the first battle......

After Ali was ordered, he mobilized the navy to disperse and set off down the Yalu River. In order to hide his whereabouts, he sent advance personnel to reconnoiter in Goryeo in disguise. The first is to survey the waterways and grasp the tide conditions; The second is to investigate the topography of Shenmi Island and the deployment of the Song army on the island. He planned to enter the Korean Gulf from the mouth of the Yalu River, and then marched along the coastline of Goryeo to avoid the Song Dynasty naval fleet cruising in the open sea, and used the method of heavy surprise attack to take the island of Mimi in one fell swoop, and then took advantage of its favorable conditions close to the mainland of Goryeo to quickly land and complete the planned battle plan of detouring behind enemy lines.

After learning that there were less than 1,000 Song troops on the island, and there were only two warships, and that the patrol fleet of the Dengzhou Navy had just completed the replenishment and repair of the island, and went to the open sea to carry out the blockade mission, and after a large number of merchant ships from various countries anchored in the port of the island, he felt that the time had come, and he rushed to send troops after the Ming Wu, which could not only make a war achievement, but also those merchant ships could become their own trophies, which was a golden opportunity for the naval army that had not had the opportunity to plunder in front.

On 22 August, taking advantage of the high tide to enter the sea from the Yalu River, the Jin army entered a small island 50 miles away from Minami Island and waited for a hidden back, evading the reconnaissance of the sailors of Minmi Island. The Jin State Navy was transformed from the infantry cavalry army, and the establishment was roughly the same, and the names of the generals were quite similar to those of the Song Dynasty.

After dark, the commander of the capital ordered the former army commander Wuyan Puluhun to lead 10 Wanhu warships and 100 Qianhu warships to set off as the main attack. The Chinese army commanded the Chinese army and the landing force composed of 30 large ships and more than 200 small and medium-sized warships, and Ali commanded the whole army at the flagship of the Chinese army. Later, the commander of the army, Chi Zhanhui led ten large ships and 100 medium-sized warships to guard the sea, preventing the patrol fleet of the Great Song Navy from reinforcing Shenmi Island and intercepting the Song army and merchant ships that had escaped the net.

The former army of the Jin Navy took advantage of the night without moonlight to sail to Shenmi Island by starlight, and the waning moon rising after approaching the island in the second night cast a little shadow on the sea, and the fleet disappeared from time to time in the waves, making it difficult for the observation post on the west of the island to find out, and when they saw the clouds on the island from the high lookout on the top of the mountain that have not been extinguished for navigation for many years, they began to speed up, which shows that the Jin army has made a lot of effort for this raid......

However, the Song Dynasty knew in advance that the Jin army would take action, although it did not know the details, but still made arrangements, the Weiyuan ship anchored outside the harbor as a warning post was all out at the moment, floating quietly on the sea, looking like a common reef in the sea from a distance in the dark night, the Jin army warship close to the port had just emerged from the horizon, and they were discovered. Because there are often merchant ships sailing here at night in the port, they did not dare to conclude at this moment that it was the Jin army warship, but they only entered the guard, and the sailors entered the battle position.

The Weiyuan is a three-masted and twenty-slurry medium-sized warship equipped by the Great Song Dynasty Navy, with a crew of 210 people, which can be propelled by wind or paddled by manpower, and is an offshore combat ship. However, the combat effectiveness is not weak, each side is equipped with six 10-pound rapid-fire guns, the bow has a 20-pound front-loading gun, and the stern is a 10-pound mortar gun, a total of 14 guns, in addition to five 10-barrel large-caliber machine guns for close combat, and the bow is equipped with an iron angle of attack, which can be used to ram enemy ships.

When the Jin fleet gradually appeared in front of the Weiyuan, the captain Song Yi had already concluded that it was the enemy who came to sneak attack, but he did not order to fire at the moment, but wanted to wait for them to enter the range of the ship's guns to make a counter-sneak attack, so the Weiyuan quietly adjusted its position and aimed the port gun, which was most convenient for firepower, at the direction of the enemy. Song Yi found that there were not many large ships in the attacking enemy fleet, most of them were small boats, with large ships as the leader, and small boats lined up in the back with goose wings. Then more than ten large ships lined up in a line, and then formed a large formation with small formations, forming a trend of advancing in unison.

"Solid shells, concentrate fire on the third enemy ship on the north side of the enemy formation, then turn the bow of the ship and insert it into the enemy formation, and after firing from the guns on both sides, it will ram the enemy's small warship, disrupt its formation and quickly turn and break away!" Song Yi could already see the flag fluttering on the enemy ship, and the order was delivered to each battle position through the sound of the bamboo tube.

"Raise the lights to warn, and the first shot to warn fire!" The two ships were about five hundred paces apart, and the enemy ships were already within range, and the Weiyuan could no longer hide its tracks, Song Yi ordered.

"Raise fire, enemy attack, supreme vigilance!" With the sound of the order, three red lanterns were raised on the mast, and the lights were lit at the same time at each battle position, and the bow gun fired into the air to warn them.

The whereabouts of the leaked enemy fleet did not stop, and a battleship in the formation broke away from the group and accelerated towards the Weiyuan, this is a tall fighting ship, the monster drawn on the bow of the enemy ship can already be seen in the light, the crossbowmen are standing behind the female wall on the side of the ship, and the batter on the ship has also been raised high, and the personnel under the artillery cart stand still with a cable in their hands, and enter the combat state.

"There are really people who are not afraid of death, shoot!" Although Song Yi's Weiyuan was much smaller than his opponent, he didn't realize it at all and gave the order to shoot.

In order to prevent damage to the ship due to the strong recoil generated when the guns were fired, the guns rarely fired in a salvo, and the port side guns of the Weiyuan began to fire sequentially. Although the artillery at this time did not have a gunsight radar, or even an optical sight, it was on a rocking warship, and even at such a close distance, the hit rate of the original artillery can be imagined.

But today God seems to favor the Weiyuan, five of the shells fired by the six guns missed, and several water columns exploded on the left and right of the enemy ship, but one cannonball hit the main mast of the enemy ship like a divine help, and the sails slid down with the fall of the mast, which immediately caused a great chaos, and the enemy troops on the ship dodged one after another, scattered and fled, and the speed of the ship slowed down.

"Lean in at once, shoot the starboard gun, sink it!" The first round of shooting was successful, Song Yi was overjoyed, and immediately ordered the Weiyuan to move and speed up to catch up.

In the sound of the oarsmen's horns, the Weiyuan quickly turned the hull and aimed its bow at the enemy ship to meet it, and the Jin army warship that was still in the wind also wanted them to rush over, the two ships quickly approached, Song Yi was not a fool It was impossible to give the Jin army the opportunity to use the slap stick, and when the two ships were staggered at a distance of fifty paces, they braved the rain of arrows and the cannons falling from the sky, and ordered to shoot......
