On the one hand, Xing Zhengnan's caution and good at capturing fighters, on the other hand, Wang Ji (Da Guangxian)'s arrogance and self-righteousness, the battle has not yet begun, and there is actually no suspense about the outcome of the battle. Therefore, when the only one who was lucky enough to get rid of the pursuit of the Zhou army's scouts and scouts, and the Bohai Navy scout horse with two feather arrows on his back, tried his last bit of strength to report the news that the Zhou army's 5,000 men and horses had entered less than three miles away from his own camp to Wang Ji (Da Guangxian), who was woken up from his sleep and was full of displeasure, and then fell to the ground and died, the latter's first reaction was not how to deal with it, but stubbornly thought that the scout horse was lying about the military situation, and kept repeating "Impossible, impossible, It is impossible for the Zhou army to send troops to rescue their enemies." However, facts are facts, and they are not subject to human will. Without waiting for the strategists and confidant generals who arrived to come forward to persuade their lords to accept the reality and think of quick countermeasures, the shells of the Zhou army had already roared down on the Bohai naval camp and exploded violently. Immediately afterward, there was a loud burst of gunfire and shouts of killing.

Suddenly attacked in the middle of the night, and it was such a violent attack, that the Bohai Navy, which was sleeping, fell into a panicked chaos. The defensive formation hastily formed by a handful of brave men under the organization of low-ranking officers was either shattered by shells falling from the sky, or was swept down and scattered by the infantry of the "Flying Dragon Army" who followed the barrage with dense firepower. The Bohai Navy in the west, south, and north of the city of Kaizhou was inevitably and irretrievably eroded. Some of the Bohai naval generals saw that although the enemy army was fierce, they basically advanced from west to east along their own camp, and they thought that as long as they escaped from the camp, they could escape. However, they had only just rushed out of the camp gates on the north and south sides of the main camp, and they were met with a head-on attack from the blocking detachments of the cavalry regiment of the "Security Army" that had been waiting for a long time and had received fire support from the cavalry regiment of the "Flying Dragon Army" division.

In a sense, today's Wang Ji (Da Guangxian) is both unfortunate and lucky. said that he was unfortunate because he was already victorious, but when he was about to break the city, he was caught off guard by the Zhou army who should not have appeared here. said that he was lucky, because the ghost sent him to temporarily change the Chinese military tent that was supposed to be set up in the west of the city to the east of the city. In this way, when the Zhou army began to attack from west to east, he was left with much more time to respond and prepare than in the west of the city. So, after being awakened from unrealistic fantasies by the sound of cannons and getting through the initial stage of helplessness, Wang Ji (Da Guangxian) understood his situation and quickly made the right decision. On the one hand, he concentrated all the crossbowmen in the eastern camp of the city in the area where the east camp met the north and south camps of the city, and ordered all the soldiers who came within a stone's throw of the camp in the east of the city to be killed, so as not to let any of the defeated soldiers enter the camp to prevent it from breaking the camp that was still relatively intact. On the other hand, he ordered all the units of the battalion in the east of the city to assemble as quickly as possible -- the focus of the Zhou army's assault at the beginning of the war was the camp in the west of the city, and the focus of its artillery attack was naturally there. When the camp in the west of the city was broken through, the artillery fire of the Zhou army was changed to extend the shooting along the Bohai naval camp on the north and south sides of the abandoned city of Kaizhou to cover the attack of its own infantry, so the Bohai camp in the east of the city was only a general ** shooting, which also gave Wang Ji (Da Guangxian) the opportunity to transfer troops.

Of course, Wang Ji (Da Guangxian) did not make such an arrangement to stick to the camp in the east of the city and fight to the death with the Zhou army who killed his own rout. In fact, whether it was from the deafening sound of guns and cannons, or from the morale of the rainbow shouting and killing, Wang Ji (Da Guangxian) had long judged that the enemy attacking was indeed as the messenger said, not the Liao State that had been cut off, but the Zhou army that was galloping across the territory of the Liao State, and its number was probably not less than 5,000. Although the number of his own soldiers and horses was nearly three times that of the Zhou army, the news he learned through various channels made Wang Ji (Da Guangxian) very clear about the gap in the combat effectiveness of the two sides, and understood that the Bohai Navy, which had only been recruited for two months and had not gone through any major battles, was not the opponent of the Zhou army, which had defeated the 300,000 Liao army with less than 40,000 horses and captured the 16 states of Youyun, and had been invincible all the way since the Northern Expedition. Even if the opponent is only 5,000 people.

In fact, since the beginning of the "restoration of the country" by Wang Ji (Da Guangxian), he never thought that he would be able to compete with the Zhou army on the battlefield. Whether it was inciting the Bohai people in Ningzhou, Fuzhou and other places to desperately resist the acceptance of these prefectures and counties by the Zhou army, or co-opting and provoking the Bohai people in other areas of Tokyo Province and instigating them to make trouble for the Zhou army and the Great Zhou government, the purpose was not to rely on these people to defeat or even drive away the Zhou army, but only to hope that the former's actions would delay the time for the Zhou army to seize the entire Tokyo Province and even end the entire Northern Expedition, so that they could have the opportunity to control both sides of the Yalu River (Yalu River) and the surrounding areas, and establish a regime belonging to the Bohai people themselves. After that, he quickly paid tribute to the Great Zhou court, and finally took advantage of the superficial psychology of the Central Plains regime to value fame, face, the so-called "benevolence, righteousness and morality", and the so-called "all countries come to the court", so as to provide favorable conditions for himself to restore the Bohai State and obtain the canonization of the Central Plains court.

And the reason why Wang Ji (Da Guangxian) sent crossbowmen and gathered soldiers and horses in the east of the city had only one purpose, that is, to escape. In his opinion, if he can't stop the impact of his own soldiers and horses scattered in the direction of the north and south of the city on the east of the city, the originally neat east camp will collapse like the former in an instant, and even if he can take advantage of the chaos to escape, the Zhou army that followed his own rout will immediately go out of the camp to chase, but he is afraid that if he does not run to the Yalu River (Yalu River), he will be caught up by the other party and become a prisoner or even a different place. Therefore, sending crossbowmen to guard the junction of several large camps to prevent the onslaught of his own rout was now an inevitable choice - whether those crossbowmen would end up dead or alive was not in his consideration. The soldiers and horses of the battalion in the east of the city were assembled as soon as possible to ensure that they could still have the strength to fight in the process of escaping to Yalushui (Yalu River). Even if the Zhou army ignored the rout in the Bohai naval camp and really caught up with him, with the 5,000 men and horses in the camp in the east of the city in hand, he could still turn around and block it, and buy time for himself to continue to escape. If the Zhou army fails to catch up in time, then these 5,000 soldiers and horses will be an important reliance on their lives and even their comeback on the side of the Goryeo.

Wang Ji's (Da Guangxian)'s arrangement did play its due effect to a certain extent, when the first group of Bohai rout troops from the two camps in the north and south were shot down by their own crossbowmen, the previous rout momentum was really contained in a short period of time. Seeing that there were locust arrows in front of him, and there was a dense rain of bullets behind, and there were teams of Zhou cavalry outside the camp mercilessly harvesting the lives of those Bohai Navy generals who tried to escape from the camp, and thousands of Bohai routers who didn't know where they should flee there were not advancing, retreating, or going for a while, except for a small number of brave people who held the idea of dying, forward, backward, and to the camp, and even launched a meaningless suicide attack in the direction of the abandoned city of Kaizhou. Most of the other Bohai routs were squeezed into a small space, screaming in despair, cursing loudly, hiding their faces and crying, or kneeling to beg for forgiveness. Xing Zhengnan, who personally commanded the Zhou army's assault on the Bohai naval camp, immediately adjusted his deployment after discovering that the situation had changed, and on the one hand, ordered the 15th Regiment of the Fifth Composite Infantry Division of the "Flying Dragon Army" to strengthen its firepower and continue to drive the Bohai defeated troops to flee to the camp east of the city; On the other hand, he ordered the artillery support fire to quickly adjust the target, focusing on attacking the Bohai Navy crossbowmen who were blocking the rout from entering the camp in the east of the city, and increasing the intensity of the bombardment of the camp in the east of the city, so as to complete the set combat mission.

On the one hand, the Zhou army's artillery fire was very fierce, and on the other hand, he found that the robes behind him who thought they would come to support him were rushing towards the outside of the camp. And those Bohai routers who were trapped in place were only slightly stunned after discovering that the rain of arrows in front of them suddenly stopped, and then shouted in unison and continued their own route. Thousands of routed soldiers not only quickly caught up with those crossbowmen, but also dispersed several Bohai naval battalion-level arrays in the camp in the east of the city, which had not yet had time to follow their lord because of the slow assembly speed and had not yet had time to follow their lords to "turn" into the Yalushui (Yalu River), wrapping all these former robes into their own fleeing army, and rushing towards the direction of the camp gate in the east of the city. It's just that after all, the two legs of a person can't outrun the four legs of a war horse. Before they could approach the camp gate, the cavalry of the Zhou army, who was in charge of blocking the perimeter, had already blocked the gate in front of them, completely cutting off their last hope of escaping.

Seeing that there was no hope of escape, the Bohai routers, who had been exhausted by the encirclement and interception of the Zhou army, finally collapsed completely, and knelt on the ground one by one in the shouts of the Zhou army abandoning their weapons and surrendering without killing, leaving their fate to the latter to decide.
