Yang Hao stood on an earthen platform closest to the front line and watched everything that happened on the battlefield, and beside him was a group of senior staff officers who specialized in siege operations, including veterans who had been in battle for a long time, young talents who had not yet come out, and more senior staff officers who were in the prime of life.

Hundreds of military states in the Tang Dynasty, almost every state and county have built a city wall, siege is a university question, since ancient times to study the siege of the city and defend the city of the book of soldiers, so the famous generals are also like a galaxy, the main enemy of the Xining army since the establishment of the army has been the nomadic tribe on the grassland that does not build the city wall, and Yang Hao himself is a person who advocates attack, so the Xining army won the respect of the grassland opponent at the same time, and did not get the recognition of the surrounding towns that are good at defensive operations,

In the previous siege battles in Hedong, even if the troops have an absolute advantage, each victory is exchanged for a mountain of corpses and a sea of blood, Yang Hao is very sad about this, he is eager for some innovations in technology and tactics to avoid this desperate casualty, Yang Hao handed over this important subject to the Armed Forces Academy, and asked all divisions and battalions to fully cooperate,

Tan Kong recommended to Yang Hao a veteran with paralyzed legs, this person is named Hu Poshan, who has served in the military department for many years, participated in many wars against local feudal towns, and has rich practical experience in siege operations, as well as deep theoretical literacy.

The biggest highlight of his life is the eleventh year of Yuan He, following Tang, Sui, and Deng Jiedu to make Li Yu lead the army to crusade against Wu Yuanji's rebellion, as Li Yu's counselor military, Hu Poshan planned a strict advance and retreat strategy for Li Yu, and in the winter of the following year, according to his planning, Li Yu seized the fighter plane, conquered Caizhou on a snowy night, captured Wu Yuanji, and achieved a reputation through the ages.

Years of war so that Hu Poshan is injured, in his later years he was paralyzed, can only be accompanied by a wheelchair all day long, he was honest and self-disciplined when he was an official, two sleeves and a clean breeze, with a son and two daughters, died young, after his legs were paralyzed, he was even more difficult to make a living, often ate the last meal without the next meal, he still did not forget to compile what he had learned in his life into a book in the hardships and hardships, in order to warn future generations,

Yang Hao hired him as a professor of the Fengzhou Wubei School, specially allocated him a house, hired two servants for him, and let the resident physician of the school come to the door every half a month for Hu Poshan to have a physical examination.

He set up a society, received seven closed disciples, specifically to teach siege, defend the city, he and a group of craftsmen of the Ordnance Department pondered some new siege equipment, because of the huge cost, the Ordnance Department is unwilling to invest in the build, Yang Hao learned of the situation, personally approved a fund for Hu Poshan to develop new siege weapons,

Hu Poshan's arrival made a qualitative leap in the Xining Army's siege operation theory, all kinds of talents continue to emerge, before sending troops to Shuofang, the Xining Army has carried out siege combat exercises many times, and each battalion has made great progress in siege skills, now what is missing is only the test of actual combat, Yang Hao chose Wuhai City as a breakthrough to beat Shuofang, to a certain extent, it is also the result of Hu Poshan's efforts,

Hu Poshan assured Yang Hao that as long as he followed the siege strategy he had formulated in advance, he would definitely be able to capture Wuhai City in less than two days, and the casualties of each battalion would not exceed 500 people.

The siege plan was jointly formulated by Yu Chongchong and Hu Poshan, Yu Chongchong is a former enemy commander and a well-known general who is good at defending the city, so Yang Hao is more at ease when he participates.

Everything is steadily advancing according to the battle plan, and it is going very smoothly, after the rush car is moved to the edge of the trench, the soldiers quickly set up the pontoon bridge, the pontoon bridge is made of a few logs made of a kind of ladder-like thing, the wooden bridge is folded into two sections from the middle, connected by hinges, the wooden bridge is hidden in the rushing car during the attack, after advancing to the edge of the trench, the tripod is built with wood, the top of the tripod is equipped with pulleys, the rope is tied to the wooden bridge at one end, and the other end hangs down through the pulley, and the wooden bridge is slowly lowered after choosing the position, and the position is slightly adjusted, a pontoon bridge was successfully built on the trench,

The advantages of this kind of pontoon bridge are very obvious: dexterous and lightweight, easy to transport, easy to build; The disadvantages are also significant: the passage capacity is poor, only infantry can pass, cavalry and heavy equipment cannot pass from above,

In order to prevent the pontoon bridge from being burned by the opponent's rockets, the surface of the wooden bridge is coated with a layer of special wood paint to isolate the flame burning, and if there is no such wood paint temporarily, a layer of thin mud mixed with crushed grass can also be applied on the surface, and the fire prevention effect is also very good.

However, the catapult was fixed on the battery, and it had been completely lost under the rocket attack of the Xining Army, and the remaining two were so badly damaged that they could not adjust the attack angle, and they almost became dead guns.

Hu Shide realized the danger, and when he was actively considering countermeasures, Min Lan, the guard of Xicheng, ran over panting and said: "The last general, please order to open the city gate and attack, otherwise it will be dangerous for them to build a pontoon bridge in Xicheng." ”

Hu Shide flatly refused: "Don't open the city gates." He pondered for a moment, pointed to the two secret gates in the southeast corner, and said: "Open the two gates B and C, and you will personally lead your troops to attack, and you must destroy the enemy's rushing cars and pontoon bridges." Min Lan was overjoyed and said, "Delingli." "Immediately gathered three hundred sergeants of the headquarters and two hundred cavalry of the front army in two teams to prepare for the attack,

The secret door is also called the protruding door, it is a special facility on the city wall, it has been reserved when the city wall is built, it is usually sealed with bricks and soil, and the outside is smeared with mud, which is used to camouflage and cover up, it is completely impossible to see from the outside of the city wall, and when you want to surprise the enemy besieging the city, open this door from the inside, launch a surprise attack, and often achieve a surprising winning effect,

After the Tiger Battalion's rushing car built a pontoon bridge at the water's edge, it was not in a hurry to attack, Yu Chongchong wanted to lure the Flying Fish Army to attack from the secret gate, if this threat was not eliminated before the general attack, it was undoubtedly a great risk.

The B-shaped door was opened first, Min Lan personally led the three hundred soldiers of the headquarters to kill from the secret door, and rushed straight to the pontoon bridge by the water, the archers on both sides were suddenly busy, and each poured arrow rain into the opponent's position, suppressing the opponent's archers to protect their own attacking soldiers, the archers of the Flying Fish Army took advantage of the terrain, they were condescending on the city wall, and soon forced the tiger battalion soldiers marching in the wilderness into the rushing car,

Min Lan led the crowd to rush to the moat, the soldiers slashed and slashed to try to destroy the pontoon bridge on the river, and the strong bows and crossbows in the car kept shooting and killing the soldiers who destroyed the bridge, the distance was so close, almost every arrow had to take a life, the moat was full of corpses, and the originally clear water was stirred yellow,

"Rush with me."

Min Lan took the lead, brandishing a big knife to kill the rushing car, the pontoon bridge originally built for the attack, but at the moment it was convenient for the enemy's counterattack, which seems to be a kind of irony for the attacker, but this is not the case, the pontoon bridge can only be used by two people side by side, if you want to go fast on the bridge, it can only pass one after another, which makes the attacking soldiers unable to use shields to protect themselves, because there are six shooters guarding on the opposite side of each pontoon bridge, and every soldier who steps on the pontoon bridge will be attacked by the front, above, left, The multi-directional attack on the right side, even if you hold two shields in your hand, you can't take care of your head and feet.

Min Lan rushed to the middle of the bridge and was shot down by an arrow, and the two guards lifted him up and retreated, and the shooters of the Tiger Battalion realized that it might be a big fish, so they greeted him with an overwhelming array of arrows.

The people around Min Lan fell one after another, they fell into the water with arrows, either drowned or stabbed to death by bamboo swords and wooden stakes at the bottom of the water, but Min Lan was unscathed, he understood that the enemy might want to capture him alive, so he drew his sword in his hand, and decided to end himself at the moment of crisis, the arrows as dense as raindrops suddenly stopped, and a team of Xining army guards jumped to the pontoon bridge and rushed towards Min Lan,

They really wanted to capture me alive...... Min Lan was desperate for a while, capturing the enemy's main general alive on this occasion can undoubtedly greatly dampen the opponent's morale, Min Lan gritted her teeth and raised her sword to wipe it off her neck,

Suddenly, a stirring horn sounded, the direction of the city wall suddenly dusty, the secret door of the C number opened suddenly, and a cavalry swept over like a storm, this is the cavalry of the Shuofang front army, the front army that has always been looked down upon by the soldiers of the tooth army, but at this moment it has become the most dazzling star, they crossed the sheep and horse wall to the moat, the knights held a shield in one hand, and threw a javelin in the other, which was a hundred shots,

The soldiers of the tiger battalion who had rushed to Min Lan's side fell into the trench one after another, and the boiled duck flew so miraculously, the soldiers of the tiger camp were very annoyed, and the arrows shot at the front cavalry like a storm, people turned over on their backs, people howled and neighed, and only a third of the thirty knights who sacrificed their lives to save Min Lan escaped one life,

Woo,,

The signal for the first round of siege of the tiger battalion sounded, and the soldiers enthusiastically crossed the trenches, left the cover of the rushing chariots, held wooden shields, stepped on the pontoon bridge, braved the dense arrows and stones, and rushed to the sheep and horse wall.

This is the first face-to-face fight between the attacking and defending sides, the number of the besieging side is slightly superior, but the defenders are defending with danger, because the people on both sides are mixed together and can't distinguish between the enemy and me, the bows and crossbows in both hands have stopped shooting, this kind of face-to-face fight is the most real, training level, weapons and equipment, command art, strength level, unobstructed, at a glance,

The top generals on both sides were nervously staring at this skirmish, each was testing each other's hypocrisy, and soon after Hu Shide and Yang Hao were relieved, the two fought a draw, the morale of the Flying Fish Army was boosted, and the shadow of the failure of the estuary was swept away at this moment, and there was jubilation up and down,

The second charge of the Tiger Battalion was quickly launched, this time they changed their tactics, first using a longbow rocket array to suppress the sheep and horse wall guards, the guards' makeshift war tent was burned by the flames, the Tiger Battalion advanced in parallel with two outposts, the soldiers only had wooden shields and ladders, and the archers and the longbow array in the distance suppressed the defenders at the head of the city with arrows, providing them with not high quality cover,

The lightly armed tiger battalion is as brave as a tiger, the sheep and horse wall is immediately lost, and the hearts of the flying fish sergeants are covered with a layer of shadow, but the strong attack of the tiger battalion is not smooth, the city wall is full of pits, and the soldiers are worried about their lives if they are not careful, although the archers at the head of the city have been successfully suppressed, but the ladders that are constantly erected are quickly overturned by the wooden forks, the wooden forks used to defend the city are dozens of meters long, and the soldiers can be operated by hiding in the war tent or wood, and they are not afraid of the suppression of bows and arrows.

Hu Shide showed a rare smile on his face, and he also said to Lou Chuan: "It seems that the Xining army is only good at field warfare, and it is still not good at attacking cities." Lou Chuan wanted to say this sentence in his heart for a long time, but he didn't dare to say it because of Hu Shide's majesty, and at this moment Hu Shide started, he followed the words and said:

"The ruler is long, the inch is short, and he is not the king of heaven, how can he be strong in all aspects."

"How's going on in Beicheng?"

"Tan Rang got up early and attacked twice, but he didn't cross the sheep and horse wall, and now he is lying there and shooting arrows at the wall, I have to admit that the archery skills of the Fengzhou soldiers are good, and they are really not his opponents."

Hu Shide smiled, his expression was very relaxed, and several staff lieutenants also took the opportunity to say: "The Fengzhou soldiers seem to don't know how to fight without leaving their horses, the Fengya battalion in Dongcheng set up a few stone cannons to bombard the wall there, and the stones that came over were only the size of a fist, and only a layer of soil fell on the wall, where is this smashing the wall, it is clearly tickling the city wall......

Hu Shide didn't dare to be careless, and asked urgently: "Do they have a ladder?" ”

The staff officer replied with great certainty: "No, there are a few pontoon bridges on the ground, and there is no cover for rushing vehicles, so they are left there and no one has erected them." ”

Hu Shide nodded silently and explained: "You must keep an eye on it, don't be careless." ”

The second attack of the Tiger Battalion ended in a fiasco, and after leaving more than a hundred corpses, it retreated in disarray,
