Goryeo is located on a long and narrow peninsula, surrounded by the sea on three sides, about 2,000 li in length and about 400 li in width, due to the crustal movements, erosion and accumulation that have occurred many times over a long period of geological time, forming a variety of terrains such as mountains, plateaus, plains, valleys, and coasts. However, Goryeo is generally a mountainous country, and the mountains and plateaus occupy almost eighty percent of the land.

The north is the Changbai Mountains, the central is the Jingang Mountains, and the south is the Big and Small White Mountains, the mountains are steep, the ravines are vertical and horizontal, the forests are dense, and there are many valleys that are mixed with soil and rocks. At the same time, it is a country with many rivers and lakes in the world, with a long coastline, rivers crossing, crisscrossing the whole territory, the climate in the south is warm, and most of the rivers are not frozen or only have thin ice in winter. The plains are mostly in the west and south, and on the east coast, there are only smaller plains along the lower reaches of the rivers.

This special topography has led to the extremely underdeveloped road system in the northern part of Goryeo, and there are more than 50 mountains above sea level in the northeast, and from Jinguo to Xijing, you can only avoid the mountains in the east and go south along the west coast plain, and the roads here are also narrow, and in some places the two cars cannot be staggered. In addition to the road, there are ridge trails, especially the mountain roads are very small, and the movement of the troops is relatively difficult.

Although the complex terrain of Goryeo was greatly restricted by both sides, it was more disadvantageous to the attackers. The peninsula is long and narrow, and most of it is mountainous, and the accommodation of troops is limited, so the reinforcements sent this time are all marines who can charge on their horses and can be used as infantry dragoons and infantry troops, and do not send the most offensive hussars, and the base of Busan Port in the south is an ice-free port, which can provide uninterrupted supplies for reinforcements.

In the past, it was because the emperor was too good, too powerful. In every battle, he must personally go into battle to command, and his commanders and generals are also very smart. Also out of superstition about the emperor, he gradually lost his initiative. The emperor didn't give an order, so he didn't know what to do, and now the emperor has delegated power to them, forcing them to constantly think of ways to find fighters and complete the emperor's strategic deployment.

Zhao Yong considered that if the Song army rashly launched an attack after landing, it might be attacked from both sides by the Wushu attack of the Goryeo army and the Liaodong army of the Jin State, so Zhao Yong and the emperor divided the entire campaign into three stages, attacking in sections, and gradually completing the plan of destroying the enemy. But after sending them out, the emperor became the shopkeeper, no matter how he asked for instructions, he no longer 'interfered', but let him control the fighter himself.

After entering Goryeo, Zhao Yong first dragged the Jin army led by Wushu, entered Xijing to focus on defense, blocked the offensive momentum of the Jin army, and then used the naval army to break the blockade and gain a foothold. At the same time, use this time to complete the preparation of campaign materials and soldiers. Now the two goals have been basically achieved, the third echelon has completed the supply task, and the tiger general is rushing to the Korean Gulf. Now it's up to the trolls!

Cheng Xishou led the Dengzhou Navy Division to trap the Jin army in the Korean Bay, and although their ships and guns were strong, this section of the sea was long, and he had to divide his troops to guard the sea lanes between the various islands to prevent them from sneaking away. And the landing force had only one Marine Brigade. Even if the Jin Shui Army can be defeated, it will be difficult to complete the task of recapturing the retreat of the Sanxin Wushu army and preventing the Jin State from sending reinforcements.

Another problem was that the Kim Navy occupied the strait, with its back to Goryeo proper. After they were defeated, they had another choice, which was to abandon the ship and land to do their old job. Reconvert to an infantry army and enter the surrounding state cities that have been surrounded by the Jin army. Become a new force to defend the city. That would add a lot of trouble to the Great Song army that landed on the mainland to establish a blocking line, so how to annihilate the enemy at sea became a problem for Cheng Xishou to consider at the moment......

When the Song Shuijun pondered the Jin Shuijun, he was drinking in the camp, and he was going crazy these days, and after the last defeat, he had to evacuate from the various islands he occupied and set up a camp in a small bay near Yanzhou, and his range of activities was also greatly compressed, and he couldn't get out of this island chain with Shenmi Island as the main body. During this period, he also tried to recapture Linden Island and open a sea route to the mouth of the Yalu River, but he was repulsed.

This is just a 'trivial matter', Taishi Wushu has written several times to ask Xianmao Ali to quickly repel the Song naval army in the Korean Bay, and then go to Xijing, block the Datong River, and trap and annihilate the Song fleet that reinforces Xijing. But now the entire naval division is blocked in the strait, not to mention the reinforcement of Xijing to annihilate the reinforcement fleet, it is in danger, once the Song naval army launches an all-out attack, he can only go ashore.

But Ali didn't dare to say no, he was very aware of the temper of the vultures, and he had high hopes for spending a lot of money to build such a huge fleet under extremely difficult financial circumstances. If he reports that he is defeated in the war and has no ability to divide his troops to help Xijing, I am afraid that if he is removed from his ministry, he will most likely be skinned, cramped, and exterminated by the Nine Clans, and he will not necessarily relieve his hatred.

Therefore, Diagonal Ali discussed with a few generals, and reported that now the Song Navy has been beaten by himself in several battles and has no power to fight back, but now the sea is too stormy, and our big ships are too few to pursue in the open sea.

This lie is actually not clever, but Wushu is a layman in water warfare, he has never even sat on a boat, and two feet of waves can make him vomit upside down, where do you know that Ali and others dare to lie to him! On the other hand, water warfare is different from land warfare, and it is reported that the enemy's ships have been sunk, and no one will go to the bottom of the sea to check the authenticity, unlike the land war, which can be found out by a few heads, so no matter how you report it, you are not afraid of revealing the stuffing, and you can also get a reward, so that Ali has survived a catastrophe.

Although they temporarily stabilized the Wushu, they were still uneasy in their hearts, and they only hoped that the weather would be cold soon, forcing the Song fleet to withdraw. It can be said that he has defeated the Song fleet, and the weather is cold and does not allow him to go to Xijing again, lest the Yalu River freeze and cannot be withdrawn to the country, resulting in damage to the warship, most of them will be allowed to leave the battlefield and return to China for the winter.

"Report to the capital, today the landing force of the Song Army began to withdraw from Linden Island and Da, Xiaohe Island, and gathered on Shenmi Island!" The commander of the Jinshui Army's patrol post reported in the account.

"Oh, the Song army gave up those islands!" I don't know how to be a good slanted Ali is now in addition to asking the shaman in the camp to pray to the gods to make the weather get cold soon, he is hiding in the handsome tent and drinking alcohol, and asked a little excitedly after receiving the report.

"Yu Du Tong, the last general specially sent people to the island to see, the island is empty, and the camp tents have been burned, absolutely true!" The Commander affirmed.

"Well, I've rewarded you for this wine, go and invite a few generals to the tent to discuss matters!" Although he didn't know Song Jun's intentions, he didn't think it was a bad thing, and said with a long-lost smile on his face.

The little commander who was unexpectedly rewarded was very happy, wine can be said to be the favorite thing of people floating on the sea, not only can keep out the cold, but also relieve boredom, but in recent years, the food is not enough to eat, wine has become a luxury, only those high-ranking officials and nobles can enjoy things, he has not tasted wine for a long time, and he will soon invite the commanders of the three armies of the navy to come!

"What do you think of the Song army's evacuation from the islands?" Ali asked, looking at the generals.

"Dutong, the last general thought that the Song Shui Army wanted to withdraw the army, and the place near the sea has frozen in the past two days, and I am afraid that I will not be able to leave if I don't leave!" Atu Han, the commander of the Chinese army, spoke first.

"In the end, it is not necessarily that the Song Dynasty naval army will withdraw, if the sea is frozen, the islands will be connected into a piece of land, and they can be withdrawn to Shenmi Island at any time, so why bother to leave now!" The former army commander, Uyan Puluhun, shook his head and did not agree with Atuhan's statement.

"I thought this was the harbinger of the Song Navy's evacuation, the Song Navy's army was different from us, they could only beg for a living on the ship, they could not land and fight, I saw that the strength of the island was only more than 2,000 people, and they relied on the artillery cover of the warships to defend the island on weekdays. And now that the naval army is going to withdraw, they are worried that we will retake the island, so they will concentrate all the defenders on Shenmi Island, where the city defense is strong, and a large number of materials are hoarded, which is convenient for long-term defense, and it is an important base for the Song Water Army. Atuhan insisted on his point and argued.

"I'm worried that the Song army is cheating, they are the best at making a plan to attack the east and west, they want to lead us to the sea to strike, they take the opportunity to land on the mainland, cut off the return route of the Taishi!" Wuyan Puluhun once led the army to participate in the battle of Juyong Pass, and was led by the Song army to run east and west, seemingly victorious everywhere, but the result was defeat everywhere.

"Chi Zhan Hui you have and opinion!" Seeing that Atuhan was about to argue again, Ali preemptively asked Chi Zhanhui, who had not yet spoken.

"All the commanders, the last general thinks that the two commanders are reasonable. Now that the weather is cold, it is not unreasonable for Song Shuijun to prepare for evacuation; However, the battle in Xijing has reached a stalemate, and the Song army has not launched a major war, so it cannot be said that they have no possibility of outflanking us by two routes, and adopt the same tactics that we used to seize Baozhou, but they are worried that our naval army will go ashore to fight, so they want to transfer us out of the strait. Therefore, the last general thought that he should not rush to conclude that the Song Navy's army would withdraw, but should strengthen reconnaissance and closely monitor the movements of the Song Navy's army before making a decision! Chi Zhanhui was not offended on both sides, and explained his opinion.

"Well, you all have a point!" Seeing that there was a difference between the two sides, he swallowed back what he wanted to say, "Wuyan Pulu Hun will send troops to the island tomorrow to test the reaction of the Song army, Chi Zhanhui, you will send more sentry ships to find out the movements of the Song naval fleet, Atu Han, you will strictly guard the water village to prevent the Song army from cheating!" ”…… (To be continued......)
