These 400 people were led by Zhang Tiangang, who took advantage of the hesitation of the Goguryeo people in front of the prison city, and led a hundred master guards and 300 elite soldiers to rush forward. The other 300 elite soldiers lined up in front with spears and bows and crossbows, and 100 of them were scattered behind the flanks with short swords and light shields to cover the two wings.

When the four hundred men rushed to a distance of thirty or fifty paces, the crossbowmen fired arrows, and the swordsmen, bayonets, and pikemen rushed forward to engage the enemy under the cover of the high shields.

The Goguryeo people who were in front of the stronghold only confirmed at this time that the four hundred people who rushed over were really disguised enemies, and the Goguryeo people who were approaching on both sides and were caught off guard scattered arrows, and then looked at the menacing fleet approaching Bailing Island in the distance, coupled with the combat power shown by these four hundred people, they were startled, and they did not dare to fight in the field, and quickly retreated to the prison city in a panic.

The generals who commanded the 2,000 armies of Goguryeo led the men to retreat into the stronghold, looking at the strength of the 400 enemies, and ignoring the fact that there were still more than 100 people who could not retreat, and shouted: "Close the gate, quickly bolt the gate to death; The people in the city all went up to the wall and shot arrows hard, so that it was possible to save more than 100 brothers from outside. ”

"Send the order to go down and burn the wolf smoke, several piles of wolf smoke are burned, the fleet of the Great Sui people is so large, I am afraid that there are more than 2,000 people. Tell the brothers that if they hold on for two days, the Prime Minister will send reinforcements...... Defend Bailing Island, and the sins you committed before will be written off, and you will eat and drink spicy food, day girls, play bitch, be free, can't hold on, wait for the head to land! ”

This Goguryeo general was a shrewd man, and he would rather lose more than 100 people, and decisively close the gate of the prison first, and the 400 people led by Zhang Tiangang could not take the city gate in one go, and it would be difficult to capture the stronghold if he rushed at this time.

Seeing the rain of arrows on the wall, Wang Junlin could not wait to kill all the enemy soldiers outside the prison gate, so he caused people to blow the horn and ordered 400 people to withdraw to a line outside the arrow field, so that the crossbowmen could hide behind the high shield and shoot the enemy soldiers outside the prison gate, so that they would not have a chance to escape into the prison city.

At this time, the main force of the fleet anchored in the shallow sea in the northeast corner of Bailing Island, and the sentinel ships spread out the alert; Wang Junlin's big ship found a deep draft on the east coast of Bailing Island and docked, and Wang Junlin landed on the island.

"Fuck the thief, the Goguryeo people of the dog day are really ruthless, they lost more than 100 people outside, rushed to close the prison gate, and didn't take the prison gate all at once, this is really a hard battle." Zhang Tiangang ran back and said hatefully.

Wang Junlin frowned slightly, turned his head to Liu Yidong next to him and said solemnly: "Liu Yidong, if you are fully responsible, how do you think this battle will be fought?" ”

"My lord, we also know the reality in the prison city, there are high ground on both sides of the prison city, you can use the high shield to cover, pile the earth platform and the prison city at the same height nearby, remove the pallet on the ship, directly build a cloud bridge between the earth platform and the prison city, and take the cloud bridge to forcibly attack the prison city...... Liu Yidong already has a set of plans in his heart to attack the prison city.

Wang Junlin nodded and said, "Dismantle five long-range strong crossbows from the ship and attack the prison gate and the wall of the front prison city to attract Kou soldiers, so that it will be easier to storm from the two sides of the earth platform and the cloud bridge." ”

"My lord, it would be better if you just dismantled a few catapults and smashed open the gate directly......," Wang Junlin said.

"It's just this little prison city, the gate is so dilapidated that there is no need for catapults." Wang Junlin shook his head and continued, "Besides, the catapult on the ship is very troublesome to dismantle, and it is completely possible to penetrate the city gate by using a long-range crossbow to close the distance, but the prison city is relatively close to the coast, and a ship with a thousand stones is close to the port, so it is completely possible to throw a shot on the ship to attack the prison city." ”

Catapults of this era used manpower or heavy objects to pull the tail violently, fire stone projectiles, and throw them at the enemy position, and these catapults could not be installed on ships.

Because the catapult launched by manpower needs to have space for people to run and pull the crossbow tip, which requires a distance of dozens of steps, and the big ship that Wang Junlin is riding on is only fifty steps long in front and back, and the maximum length of the main deck is only about twenty steps, so it is impossible to install a manpower-launched catapult, let alone other warships.

The reason why the catapult designed by Nie Xiaoyu can be used on the warship is to use the heavy object to drop and pull the crossbow tip to launch a stone projectile, which is to tie a heavy object at the tail of the crossbow tip, first raise it to a certain height, and at the moment of cutting the rope, the heavy object slams down, pulls the crossbow tip, and throws the stone bullet in the tip scalp.

Moreover, the catapult designed by Nie Xiaoyu is small in size, and when firing stone bullets, it will not produce a huge vertical drop force that destroys the deck, so it can be installed on the ship for water warfare, which is one of the secret weapons of the Snake Island Sailors to which Wang Junlin belongs.

The smoke burned in the prison city went straight to the clouds, almost a hundred zhang high, and the wolf smoke blew the sea breeze and gathered but did not disperse, according to the Goguryeo officers and soldiers who defended the city were actually the same number as Wang Junlin and his party who came to attack, but just now the combat power shown by a hundred master guards leading three hundred elites suddenly frightened the Goguryeo people in the prison city, plus these two thousand people were able to return to Bailing Island, indicating that the plan of Dami Island has failed, originally their two thousand people were to ambush Wang Junlin and his party fled from Dami Island to the remnants of the army, Now look at these two thousand people like remnants.

Therefore, while the Goguryeo people chose to defend the prison city, they expected Prime Minister Yuan Taizuo to send reinforcements in time.

Soon, Liu Yidong was ready to forcibly attack the prison city.

On the high ground south of the Bailing Island stronghold, five long-range crossbows were erected.

In addition, Liu Yidong mobilized six warships with a weight of 1,000 stones, and the catapults on them were loaded with loose stone bullets in the scalp puffs of the catapults, and they were also ready to shoot at the prison city.

After a fierce attack, the gate of the prison city began to shake, and six thousand stone warships on the catapult fired stone bullets, after three or five rounds, a third of them accurately hit the wall of the prison city, twenty or thirty pounds of round stone bullets, thrown at a distance of four or five hundred steps, smashed the wall of the prison city shaking, the Goguryeo people on the city wall hit more than a dozen people, immediately the flesh was bleeding, seeing that their lives were not guaranteed, other Goguryeo people were frightened and had to retreat from the city wall.

The consciousness of sea power was not formed in the minds of the monarchs and ministers of various countries in this era, even in a pure island country such as the Wa Kingdom.

Among the emperors and generals of the time, although some people were aware of the existence of naval warfare as a form of warfare, the Great Sui also had three naval divisions, and Goguryeo had 30,000 naval divisions in the south and 10,000 naval divisions in the north because of the sea on the north and south. The Baekje and Silla kingdoms also prepared for the establishment of water camp boats in coastal areas, but the main defense against pirates, including the Great Sui.
