In mid-February, although the northern part of Kyushu Island is still cold in spring, the weather has warmed up, the snow has melted, the stream is rapid, and the insects and birds can already hear the spring mood. In the southern part of the Goryeo Peninsula, which is separated by water, the land is still covered with snow, and there is no breath of spring coming.

Due to the influence of the two opposing currents in the north and south of the Goryeo Strait, Jeju Island (Danna), which is only 80 or 90 miles apart from the north and south, also has a significant climatic difference between the north and south in early spring.

The snow at the southern foot of Mount Sunrise is beginning to melt, and the northern foot is still a world of ice and snow.

In the camp at the northern foot of Mount Sunrise on Jeju Island, Lin Lian's eyes looked at the snow line on the top of the distant mountain through the curtain of the barracks door that was opened, his brows were furrowed, and his face was very ugly.

***********

The Zhenfeng Division, which was trapped in Seogwipo Fortress, has made frequent changes in recent days, competing with the guard battalion for control of the northwest and northeast sides of Seogwipo Fortress, which also means that the large-scale operation of the Goryeo army to cross the sea to aid Seogwipo is about to begin.

After the Hai Duong / Navy Army was disabled, the Minister of Urging, who was responsible for re-organizing the Navy in Hai Duong County and serving as the commander of the army, was a veteran general with rich experience in water warfare and army management.

The warships of the Goryeo Navy were far from enough to compete with the Jinghai Battalion on the vast sea.

On the southwest coast of Haiyang-gun, there are thousands of islands and sands, reefs, and twists and turns of the coastline, dividing the shallow sea into a complex area known to the Goryeo people as the Thousand Reef Sea.

For the Jinhai-class and Jiyun-class warships with deep draft and large hulls, the Qianjiao Sea is simply a nightmare, but the warships of the Goryeo Navy are small and shallow, and they are like fish in water in the Qianjiao Sea.

A battalion of soldiers and horses left behind by the Huaidong Navy in Jeju was divided into three teams to patrol and monitor the sea area north of Xibeipu every day, and drove out the Goryeo Navy sentinel ships coming from the north.

Just three days ago, a naval army left behind on Danluo Island pursued the defeated Goryeo naval army due to belligerence, and lured it into the waters of Qianjiao. When entering, the tide is high, and the Jiyun-class warship can easily sail in; When it was time to withdraw, the tide receded, and the warships of the Goryeo took advantage of this opportunity to come and join the siege.

In the end, except for two large-wing ships that broke out of the encirclement, this naval army was almost completely wiped out in the Liangming Strait in the north of Wando. The biggest loss since the Huaidong Army's cross-sea expedition was caused: more than 200 war auxiliaries were killed, including a Jiyun-class warship, and four medium-sized warships were destroyed or captured by the Koreans.

After receiving the news, Lin Jian led the main force of the 2nd Water Battalion back to Jeju Island in advance to deal with the matter.

*************

"If there are too many downwind battles, it is inevitable that there will be some belligerent and underestimated enemies. Before the war, suffering some losses is also a reminder to everyone, there is nothing bad about it. Zhou Pu said in a loud voice, which can be regarded as untying the frowning forest.

"When Goryeo was at its peak, it once had more than 300,000 soldiers; Even now, the Goryeo Dynasty's control over the counties under its rule is far stronger than that of the Won. Even if you succumb to the hooves of Donghu Tie's cavalry, and the country's strength is gradually declining, it is not something that Huaidong can deal with with with all his might," Lin Jian sighed slightly and said, "This lesson, you generals must remember it well. Not only the second water battalion, but also the first and third water battalions should sum up lessons and lessons. Our water battalion generals can only be considered qualified if they can adapt to more complex water operations. ”

"Yes......" Ge Cunxin, Zhao Hu and others responded.

Lin Lian's eyes looked intently at the waters of the Qianjiao Sea to the west and south of Haiyang County on the map.

This map of Haedong is the most clear in terms of the topography of Jeju Island, and the northern part of Haeyang County only shows 12 prefectures such as Gwangju, Jeonju, and Janggye, as well as a few large islands such as Daeheimong, Naju, Wando, Bunan, and Chidori.

It is impossible to obtain a military topographic map of Hai Duong County, and it is impossible to clearly identify the thousands of islands off the coast of Hai Duong County by simply buying them from maritime merchants. It is impossible to send people to dive into the field to investigate, and it is impossible to find out the hydrogeography of the Qianjiao Sea only by relying on the oral accounts of a dozen fishermen.

"The Goryeo people took advantage of the complex shallow terrain of the Thousand Reef Sea to assemble their naval forces, and they were also clear about the characteristics of the ridge building draft of our warships from the beginning," Lin Jian pointed to the location of the Thousand Reef Sea on the map and said, "Once the Goryeo naval army completes the assembly here, it will move south to Danluo Island." ”

"The Goryeo infantry army is also massing on a large scale south of Gwangju, which shows that the intention of the Goryeo people in this battle is not just to save the soldiers of Haiyang County," Zhao Hu said, "They want to use the water army to transport the infantry army south to Danluo Island and fight with us here!" ”

"This can't be blamed on the Koreans, the water and land are disturbed, just send the navy over, it is difficult to take Zhen Feng and the Haiyang soldiers back!" Lin Jian said.

"In other words, it would be me to send a naval army to pick up Zhen Feng alone, instead of taking the risk of mobilizing the three southern counties to cross the sea to fight this battle," Song Jia frowned slightly and analyzed, "Of course, under the coercion of the Donghu envoys, even if the lord of Goryeo wants to abandon the four thousand Haiyang soldiers on Danluo Island, it is impossible." ”

Song Jia's words sounded a little cruel, but forcibly organizing such a battle was not a good choice for the Koreans. I want to compare the risk I am about to take, and discarding the 4,000 Haeyang soldiers is not a big loss for the Goryeo people who have two or three million Dingkou.

"There are Donghu people who are coerced behind their backs, but there are also Koreans who have gains and losses," Lin Jian said, "Seriously, they are not without a chance to win, and our pressure is not light!" ”

The Koreans took the risk of fighting this battle, and Lin Lian's heart would not be easy. The Huaidong Army and the Danluo Army currently have the upper hand in all aspects, but in the end, they will have to face a Goryeo army with a total of nearly 30,000 men, and if they lose, the entire situation in Haidong will face the threat of collapse.

Danluo Island is only three times the size of Xisha Island, and the warring sides have nearly 40,000 soldiers and horses. In other words, if the Koreans cannot be blocked in Seogwipo City and the field battle is lost, it is very likely that the Korean people will be besieged in Jeju City.

"In this battle, we suffered losses, but we also figured out that the base camp of the Goryeo naval army was in Wando, from Wando to Seogwipo, it was more than 130 miles. Even if the main warships of the Goryeo Navy are mostly sloops and brigs, and they arrive at the northern bay of Seogwipo, it will only take two hours," Ge Cunxin said, calculating the distance between the base camp of the Goryeo Navy and the royal city of Danna, "Our sentinel ships on the northern sea, even if we can detect a large-scale sortie of the Goryeo Navy in time, when the news comes back, the main force of the water camp will set off from Jeju Sai, and the wind direction is retrograde at that time, and it will definitely be too late to intercept the Goryeo Navy north of Seogwipo...... The personal guard battalion and the army of the king of Danra should be ready to fight the Goryeo people near Seogwipo! ”

The strait between Danluo Island and Goryeo was not very wide, and the Huaidong Army had no port or supply base on the north coast of Danluo Island to anchor the main force of the water battalion.

Since it was not clear when the Goryeo people would move, the main force of the water camp was usually stationed in Jeju Port, so they could only send a small fleet to patrol that area and block the Goryeo sentry ships and scout ships.

If the Goryeo navy is well prepared, it can take advantage of this time difference to cross the strait and send reinforcements to Seogwipo Fortress.

Although it is not yet known how many reinforcements the Goryeo people will eventually send to Zhen Feng, who is trapped in Seogwipo City, it is certain that Lin Jian will no longer be able to draw troops from Chongzhou.

On Danluo Island, Lin Tie can call on the troops of the six battalions of the infantry division, the cavalry division of eight hundred cavalry, although the Danluo royal army has six battalions, there are only two battalions that have combat effectiveness and can be safely pulled to the battlefield, and the other four battalions of the royal army are all newly formed, and they can only be used as auxiliaries for the time being.

"I think we need to continue to strengthen the Dongtan camp......," Zhao Hu said.

The Huaidong and Danluo coalition forces also had limited strength, but only two large battalions were built on the periphery to blockade Zhenfeng and Haiyang soldiers to Xiguipu City.

One of the earliest camps built at the northern foot of Sunrise Mountain mainly blocked the south gate of Seogwipo facing the inland; A Dongtan camp was built on a seaside hill in the northeast corner of Seogwipo City, mainly blocking the east gate of each inland area of Seogwipo.

The west gate and north gate of Seogwipo, which are close to the seashore very quickly, did not have enough space to build a blockade camp, and will also be the main landing route for Goryeo reinforcements in the future.

At present, this area is mainly based on the camp in the northern foothills, and it also guards the main road from Seogwipo Fortress to Jeju.

"Tell me about it." Lin Jian asked Zhao Hu to tell his reasons for everyone's consideration.

"We only need to drive the Goryeo out this time to be considered victorious, and the Goryeo people obviously want to drive us out, once the reinforcements come ashore, they will no longer be willing to block us in Seogwipo City," Zhao Hu said, "The terrain of Danluo Island is also simple, like pea shells, and Sunrise Mountain rises high in the center, forming a high terrain in the center and low in the surrounding area." We assume that the final landing of more than 10,000 Goryeo reinforcements will give us an advantage in terms of troops. The Goryeo people went out of the south gate and went to Jeju by the west foothills, the road was the closest, but because the Sunrise Mountain was in the west and not in the east, and the west foot was connected to the sea, the terrain was cramped, which was not conducive to the Goryeo people to expand their superior forces. Moreover, when the Goryeo people went out of the south gate, they were directly suppressed by the camp at the northern foot of me, and there was only a rugged space of two or three miles to send troops, which was very narrow. Returning to Pudongmen in the west, it seems that they will be attacked by the Dongtan and the camp at the northern foothills, but the open terrain to the east is more conducive to the Goryeo people to deploy their superior forces, and once they can deploy their superior forces, they do not need to worry about being attacked by us...... I thought that after the Goryeo reinforcements landed, the main force would be deployed out of the east gate, and it was now necessary to strengthen the Dongtan camp, and I suggested that the strength there should be strengthened to two battalions of soldiers. ”

"Why don't you withdraw the Dongtan camp and concentrate your forces here, and fight to the death with the Koreans?" Li Ji, the prince of Danluo, asked, "After all, this side is guarding the main road to Jeju City in the south, so it is not appropriate to divide the troops of Dongtan Camp again!" ”

"Even considering that the Koreans will have an advantage in troops, we are not at an absolute disadvantage, and there is no need to give up the strategic initiative and completely take the defensive." Zhou Puluo explained.

The prince of Danluo has been practicing military books since he was a child, but he is limited by the narrow area of Danluo Island, and it is difficult to have a real understanding and experience of the art of war. The two camps here are less than seven miles apart, and they can be used as horns, how can it be possible to abandon the Dongtan camp and defend the reason here?

Lin Jian lowered his head and thought, habitually knocking on the edge of the table, as if he didn't hear the doubts of the prince of Danluo, and after a long time, he asked the generals: "Do you know how woodpeckers eat insects?" ”

"......" The generals were stunned, not knowing what Lin Jian meant by suddenly saying this.

"The battlefield of the battle is not something we can choose, it should be in the area east of the East Gate of Xiguipu, then let us eat the Korean people clean like woodpeckers eating insects!"
