Next, Lin Jian planned to let Zhang Gou and Chu Zheng spread out along the Whirlpool River and Chaobai River to the two wings, and maintain contact with the captive cavalry, but instead temporarily hid the Denghai Town Division, which had the strongest combat power, in Jinhai and did not move - this tactical arrangement, Zhang Gou and Chu Zheng were naturally happy twice, but they were extremely unhappy when they changed the old stains.

Lin Jian asked the military department to draw up a more detailed battle plan, and Chen Yan went directly to Xingyuan to ask for battle.

Chen Zhen was in the west base of the Zhujin Sea, his left arm was smashed by the splashing small half of the city wall bricks, tied with bandages, and rushed to ask for a meeting.

Lin Jian didn't have a good rest for several days, took time to take a nap at noon, there was nothing important, Zhou Bin, the supervisor of the internal guard, stopped Chen Yan from going in, and Chen Yan waited outside the courtyard angrily.

Lin Jian woke up from a nap, and didn't pay attention to Chen Zhen, when it was about to be dusk, he wanted to see if Gao Zongting had prepared a battle plan, and saw that Chen Yan was still guarding outside the courtyard gate, and couldn't help but raise his foot to kick him: "You idiot, do you have this time not to go to the military headquarters to participate in the formulation of the battle plan, and not go to the military medical bureau to see the wounded soldiers, there is a bird to block my door?" ”

"The last general is also injured, so I have come to ask the Lord to take a look?" Chen Yan was thick-skinned, and Lin Lian scolded him for just salivating and raising his injured arm to show Lin Lian.

Song Jia followed behind and pursed her lips and smiled, there were a few generals in the Huaidong Army, and there was nothing to be done about Lin Lian. Lin Jian couldn't cry or laugh - he could only let Chen Yan follow him to the council hall.

The staff officers and generals of the General Headquarters led by Gao Zongting, Wu Qi, Yang Yihang, and others have been busy for most of the day, and Ge Cunxin, Yue Zhi, and others are also busy handling various military affairs.

Zhang Gou had just arranged for his troops to camp on the south bank of the Whirlpool River, and when he came to the headquarters, he saw Chen Yan Lang'er coming in behind Lin Lian, and teased: "Has the lord ever wished you to go to war?" The good thing of reaping the battle results cannot be called Denghai Town Division, but also let the brother troops get a piece of the pie! ”

"Nonsense, there are two hundred artillery pieces in the Denghai Town Division, not the main force, send you soft girls to fight Wang Dengtai Mountain, there must be a mistake, isn't it a bad thing?" The old stain was unforgiving, and Zhang Gou said a word.

"If you have that strong quarrel, why don't you come and tell me how you will lead the first town division to fight on the south bank of the Vortex River?" Lin Jian took out a chair and sat down in front of the hall, interrupting Zhang Gou and Chen Yan's bickering, calling them to him and asking them what they thought.

"We have cleared the waterway from the mouth of the Whirlpool River, and there is no major problem for the frigate to enter the north of Wangdengtai Mountain, and Ye Ji Duodi should not give us a chance to fight a decisive battle near Wangdengtai Mountain," Zhang Gou said, "Our troops can move west along the Whirlpool River, but the further west we go, the narrower the river becomes, and the artillery support that the frigates that actually enter the Whirlpool River will become more and more limited." The captive cavalry may be at the edge of the artillery range, counterattacking to spy on our troops, and the general thinks that even if the artillery cannot concentrate its power, it should be restricted, and as long as the infantry brigade can suppress the position, it will attack slowly and westward, and it is really not afraid of the impact of the captive cavalry......"

"Zhang Gou is in harmony with the military department," Gao Zongting walked over and said with a smile, pointing at Chen Yan and scolding, "You headless fly, looking for someone who didn't find you for a long time, I didn't expect you to block the door of the lord's courtyard." The lord now hides the Denghai Town Division in Jinhai and does not use it, and he plans to use the Denghai Town Master in the future; Zhang Gou and Chu Zheng were stretched out from both wings, and in fact, they also wanted to protect the flanks of the main forces of Yanjing that would attack Yanjing directly from Jinhai in the future - so you are relaxed? ”

"Let me play on the flanks now, and if I need to do so in the future, move me to the middle again, it's no problem at all." Stale stains are a battle that they don't want to fall behind.

"Don't mess around," Lin Jian interrupted Chen Yan and asked Gao Zongting, "Has the plan been done?" ”

Wu Qi took the next step of the military plan, Lin Jian took it and looked through it, and said to Chen Yan and the others:

"The technology of artillery is far from developing to a mature stage, and an important reason why it has caused such great lethality to the captives is that the captives have no opportunity and time to adapt to the new artillery that appears on the battlefield and is far different from the traditional and war-weapon. Even if there is the so-called 'eat a trench and grow a wisdom', it still needs a process. One of our most important ideas at present is not to give them the opportunity to adapt and learn lessons. Therefore, artillery is either not used, or it is concentrated and used on the battlefield where the performance of a large number of enemy soldiers is killed and wounded at one time......"

Lin Jian pointed to Chen Zhen and asked him: "Tell me, what do you need to do to kill and injure a large number of enemy soldiers at one time......"

"If you want to kill and wound a large number of enemy soldiers at once, it is best to attract enemy soldiers to the frontal battlefield between the Whirlpool River and the Chaobai River......" Chen Yan replied.

"You're not stupid," Lin Jian said angrily and funny, slapping the battle plan that Gao Zongting and the others had spent most of the day preparing on the table, "This plan is to attract the enemy soldiers to the frontal battlefield between the Vortex River and the Chaobai River, you don't come to make a plan, but run to the entrance of my courtyard to block the door, you are really out of luck!" ”

Chen Yan was forced by Lin Lian, but he could read the whole word, picked up the battle plan, and said with a salivating face: "I just thought that the command might be worried that Hu Gouzi would abandon the capital and escape from Yanjing, and ask Zhang Gou and Chu Zheng to quickly outflank him from both wings......"

"Where will Hu Gouzi flee, are you worried that they will flee to Datong?" Lin Jian asked rhetorically, "That's just right, you can fight less, what else is there to worry about?" ”

Yanhu wanted to abandon the capital at this time and flee to Liaodong, he must go to Liaoxi, the long and narrow corridor of Liaoxi is close to Bosheng, and there are thirty or forty miles in depth, and the Huaidong army can take the sea route to fight the flank at any time - it is impossible for Yanhu to go to Liaodong, and can only flee in the direction of Datong or Taiyuan.

Even if the Huaidong Army gives up the captives fleeing west to Datong, it will have a better chance to completely encircle and annihilate the captives in Shandong and Henan, and will also achieve the strategic intention of the Northern Expedition to recover the Central Plains.

In fact, even if Yan Yu has the determination to abandon the capital and flee westward, it is unlikely that he will give up his determination to serve in Shandong and Henan. Yan Yu abandoned Yanjing and fled to the southwest, and fled to Taiyuan, so he had the opportunity to join his soldiers and horses in Shandong and Henan, and Lin was bound in the Taihang Mountains east of Taiyuan, and prepared the Taihang Mountain Independent Town Division for Yan Yu, so he was not afraid that they would flee in the direction of Taiyuan.

The defeat of the Battle of Hejin and the devastating tearing of the sea defense line were torn apart, and the generals of Yanyu were all defeated, and there was not enough time to reflect and summarize on the whole.

Immediately after that, less than seven or eight days apart, the Huaidong Army quickly kicked off the prelude to the Jinhai landing battle in a blitzkrieg situation.

Yan Lu did not abandon Jinhai and did not pull his troops to the inland hinterland far from the coast, but insisted on holding the city regardless of the direct threat of the Huaidong battleship's gunwales, which doomed the destruction of the 20,000 defenders.

Even if the Huaidong artillery technology is not mature, with the strength of the country and the casting of nearly 1,000 pieces of artillery in two years, it is enough to cover up all the shortcomings.

It took two and a half years for Lin Jian to carry out the Northern Expedition, and after the prelude to the Northern Expedition was officially opened, the ammunition consumed in several island crossbow fields in Shengsi and Haizhou accounted for half of the total ammunition produced by the Ordnance Supervision Department so far.

In addition to testing the performance of artillery and gunpowder, another major goal is to train a number of qualified gunners and artillery commanders through large-scale test firing and drills, so that the Shui Bu Corps can master various tactics for artillery use in complex battlefields on land and sea.

Maybe the artillery tactics of the Huaidong Army at this time are not yet mature, but compared to the defenseless Yan soldiers, it is much better. If you are prepared to fight or not, you can't achieve the effect of breaking through and crushing with one blow, so Lin Jian has been delayed in vain for more than two years?

Of course, Lin Jian was also very aware of the shortcomings of the artillery equipped by the Huaidong Army at this time.

At this time, the Huaidong artillery could not accurately control the casting accuracy of the bore and shell and the airtightness of the firing, and the longitudinal hit rate was very low. The technology of flowering shells is immature, and the probability of exploding the chamber is very high, so it cannot be used in actual combat -- therefore, Huaidong currently only casts long-bore guns with low flat angles of fire, and fires solid bullets to give the enemy fortresses and the enemy's dense battle formations a relatively accurate bombardment in the horizontal direction, and scatter bombs are the main ones in close-range combat.

The long-bore gun had strict requirements for the terrain and could not attack targets behind obstacles, and its use in mountainous terrain was seriously limited. Again, the firing time of long-bore guns is relatively long, and the most well-trained gunners in Huaidong can only continue to fire 20 cannons in an hour.

On the charging line of enemy cavalry, no matter how well-trained the gunner is, he will only have the opportunity to fire a solid bullet and a scattered projectile.

Theoretically, as long as Yan Hu figured out the characteristics of Huaidong artillery, pulled the main cavalry force to the hilly terrain of western or northeastern Hebei, and used scattered and intermittent charging arrays, he could effectively suppress the tactical play of Huaidong artillery.

The main cavalry force of Yanhu at this time has not suffered a major setback, including Yandong, Yanxi, Xihu, and Northwest Yi tribes, the total number of Yanhu's cavalry is nearly 200,000, but they are scattered all over the place:

There were about 70,000 cavalry on the defense line in Shandong and Henan, nearly 20,000 cavalry in Goryeo, 30,000 cavalry in Liaoyang and Liaodong in the northern capital, and 30,000 cavalry in Jinzhong, Guanzhong and Yanxi; The number of cavalry gathered by Yanhu to defend Yanjing and the periphery was less than 50,000, which was almost the main strength of Yanhu to defend the capital.

Although the number of cavalry guarding Yanjing and the periphery at this time only accounted for a quarter of the total number of cavalry in Northern Yan, these 50,000 cavalry accounted for more than 50% of the strength of the Donghu people in Yandong Zhuhu, that is, the core force of Northern Yan.

As long as there is a chance to eat these 50,000 cavalry, even if the Northern Yan royal family has the opportunity to lead the remaining 150,000 cavalry to flee westward, it will be difficult to effectively control the forces and soldiers of the Yanxi Zhuhu, Xihu and Northwest Yi tribes because of the greatly weakened strength of the Donghu tribe - it will give Huaidong more opportunities to divide Yanhu and break through.

If you want to eat the 50,000 captives west of Wang Dengtai Mountain, Yanjing and the periphery of Yanjing, you should lure them to the southeast of Yanjing and the frontal battlefield between Yanjing and Jinhai to block the guns of the Huaidong army.

Lin Jian was determined to make Zhang Gou and Chu Zheng spread out to the two wings, and temporarily hid the Denghai Town Division in Jinhai to rest, and his fundamental purpose was this.

The Huaidong Army gave priority to the use of artillery in naval warfare, and the only army soldiers and horses in the Denghai Town Division were equipped with three crossbow battalions and 200 artillery pieces on a large scale.

Zhang Gou and Chu Zheng spread out to the two flanks and made contact with the captive cavalry west of Wang Dengtai Mountain and on both sides of the Chaobai River, in order to limit the opportunity for the captive cavalry to contact artillery and find out the tactics of artillery on the field battlefield.

After the reserve soldiers and horses are transferred from the sea route, they will cooperate with the Denghai Town Division to directly approach Yanjing City from the middle road, and the captives will face the choice of either intercepting the Huaidong Army from the front, or letting the Huaidong Army calmly enter Yanjing City.

Lin Jian was not worried that if the time dragged on, there would be more captives to rush to Yanjing.

The advantage of cavalry lies in mobility, in the priority of the choice of battlefields. On the frontal battlefield of Yanjing and Jinhai, the Huaidong elite infantry brigade has warships on both wings and artillery in the formation, so there is no need to worry that the enemy cavalry will be crushed by the formation.

If the main force of the enemy's cavalry does not come to the frontal battlefield between Yanjing and Jinhai for a decisive battle, the Huaidong Army will concentrate on advancing to Yanjing; When it comes to defending the city, it will be the weakness of the Yanhu cavalry.
