When Wang Junlin entered the small city in the middle of Dami Island, he summoned the generals to hold a mobilization and deployment meeting to prepare for war.

"Goguryeo now has more than 300,000 troops, and the reason why we have the upper hand now is purely because our sailors are far stronger than them, but if you want to attack Goguryeo itself, you can only deal with it with all your might." Wang Junlin said with a solemn expression, "So we must not despise our opponents just because we easily annihilated more than 10,000 enemies last time. ”

"The adult's lesson is ......," Liu Yidong, Luo Chunlai and others hurriedly responded with their fists.

Wang Junlin nodded, and as he spoke, his eyes looked intently at the waters of the multi-sea reef sea west and south of Annan County on the map.

This map was hand-drawn by Nie Xiaoyu himself, so the topographic outline on this map is extremely clear, and more than a dozen prefectures and counties in Annam County, the southernmost part of Goguryeo, as well as more than a dozen islands large and small in the sea between Dami Island and Annam-gun, have been marked.

"The Goguryeo people took advantage of the complex shallow sea terrain with many reefs in this sea area to assemble their naval forces, and they did not dare to attack them suddenly because they knew the characteristics of the ridge-building draft of our warships." Wang Junlin pointed to the location of many reefs on the map and said: "Once the Goguryeo naval army completes the assembly here, it will move south to Dami Island or Bailing Island. ”

"According to the intelligence, the Goguryeo people wanted to use the navy as a cover, and a large number of civilian fishing boats and merchant ships were recruited to move south, force their way to Dami Island or Bailing Island, and fight to the death with us on the island!"

"Obviously, the Goguryeo people also know that at sea, their sailors are not our opponents at all, that is to say, they have given up naval battles, and are even ready to sacrifice a large number of sailors, but seriously speaking, they are not without a chance to win, and our pressure is actually not light, because their number of troops will be more than five or six times that of us."

The Goguryeo people took the risk of fighting this battle, although Wang Junlin had made full preparations at the invisible level in the early stage, but Wang Junlin's heart would not be easy.

It is true that Wang Junlin's naval division can crush the opponent's naval division, but in the end, he will have to face a Goguryeo army with a total of 30,000 people, and once he loses, the great situation that he has created in this sea area will face the threat of collapse.

Dami Island and Bailing Island are not large, and there are nearly 40,000 soldiers and horses on both sides of the war, and once the battle situation begins, no matter which island the war is fought on, there is no strategic depth for detour. In other words, if the Goguryeo people cannot be severely damaged at sea, even if they win the land battle on the island, it will inevitably be a disastrous victory, or even a heavy defeat.

"According to intelligence, the base camp of the Goguryeo naval army was located in Linguang Island, and it was more than 150 miles from Linguang Island to Dami Island or Bailing Island. Even if the main forces of the Goguryeo naval army were mostly single sloops and double masts, it would take at least two and a half hours to come downwind. Liu Yidong calculated the distance between the base camp of the Goguryeo Navy and Daemi Island and Baekling Island, and said.

Luo Chunlai also said: "If Goguryeo attacks Bailing Island, our sentinel ships on the northern sea, even if we can find a large-scale sortie of the Goguryeo naval army in time, when the news comes back, the Dami Island naval division will set out to support, and the wind direction is retrograde at that time, it will definitely be too late to intercept the Goguryeo naval army in the north of Bailing Island...... Therefore, whether it is Dami Island or Baekryeong Island, you must be prepared to fight with the Goguryeo people near the island! ”

Wang Junlin nodded and said, "Yes, since I don't know the timing of the Goguryeo people's dispatch, whether it is Dami Island or Bailing Island, from now on, the main force of the water camp is usually stationed in the harbor and is ready to dispatch at any time." In addition, a small fleet was also sent to patrol that sea area and block the Goguryeo sentinel ships and scout ships. Because, if the Goguryeo naval army is well prepared, it can take advantage of this time difference to send a large number of army troops to Baeknyeong Island or Dami Island, in which case this battle will be troublesome. ”

"Therefore, I believe that it is necessary to continue to strengthen the construction of camps and castles or defensive positions on the two islands...... Luo Chun said.

Wang Junlin's forces on the two islands were limited, and the difference between them and the opponent's forces was too great, and if he could not intercept the Goguryeo army at sea, he could only defend the two islands.

Wang Junlin nodded and said: "Luo Chun is right, although we have made full preparations in other aspects, but we must also prepare for the worst, from now on the two islands seize all the time to build defensive camps and positions, and you can prepare for the defensive warfare method of relying on the walled city of the trench that I told you before." ”

……

……

Seven days later, Wang Junlin received news that Goguryeo's army in Annam-gun had been moving frequently in recent days, which meant that the Goguryeo army's large-scale crossings of the sea to conquer Dami Island and Bailing Island were about to begin.

In charge of re-organizing the naval army in Annam-gun and serving as the main general, Choi Shengjun is a veteran general with rich experience in water warfare and army management.

The warships of the Goguryeo naval army were far from enough to compete with the sailors of Wang Junlin's side on the vast sea. On the southwest coast of Annam-gun, there are thousands of islands and sands, reefs, and twists and turns of the coastline, dividing the shallow sea into areas with complex topography, which the Goguryeo people called the Seijiao Sea.

For large warships with deep draft and large hulls, the Sea of Star Reef is simply a nightmare, but the warships of the Goguryeo Navy are small and have a shallow draft, and they are like fish in water in the Sea of Star Reef.

……

……

On the third day of August, about 500 warships of the Goguryeo Navy completed the assembly near Linguang Island, and a larger number of civilian ships were assembled on the shallow sea line of Xingjiao in the north of Linguang Island, and their task was to transport the army to Dami Island or Bailing Island to fight.

Even though there were only more than 150 miles of waterway from Linguang Island to the northernmost beachhead of Bailing Island, the Goguryeo people were still worried that the reinforcements crossing the sea would be intercepted by the warships of Wang Junlin's side in the middle of the road, and the Goguryeo naval army had extremely limited ability to defend them.

The Goguryeo people finally chose to take advantage of the blowing north wind on the night of the 11th, and the first group of reinforcements crossed the sea and headed south, in a vain attempt to land on Baeknyeong Island from the beachhead north of Baeknyeong Island.

Although Shen Guo'er lurked beside Cui Shengjun, the commander of the Goguryeo Naval Division, in an alternative way, Yuan Taizuo and Yuan Gai Suwen were very cautious this time, and until the end, even Cui Shengjun didn't know whether to attack Bailing Island or Dami Island first.

In addition, there were thousands of reefs on the outskirts of Annam, and the sentinel ships of Wang Junlin at sea could not accurately and timely find out the build-up of the Goguryeo army.
