Zhao Ta was blinded, and Wushu deceived Zhao Yong again, and the two sides were a trick, which made the battle even more confusing, making it impossible to see what the opponent was doing.

Although Zhao Yong, who figured out the cause and effect, was deceived by the Wushu, but the Jin army finally moved according to the plan, he was still very happy, and immediately arranged it, and the 4th Marine Brigade transferred to Yuanzhou immediately went out to assist Ah Shu's Five Nations Department to seize the lazy Dian; ordered the 1st Marine Brigade to defend Bochuan, and the Tiger General rushed to Tokugawa to set up an ambush to intercept the retreating Chinese army of the Jin Army; The two generals of Xijing prepared to attack the camp of the Jin army.

The former army successfully deceived the scouts of the Song army, evaded the siege, captured Xichuan and opened the way back to China, and the Jin army dispersed out of the camp with its old tricks again, and quietly left the camp and retreated north with baggage on a foggy night, while the Song army still pretended not to find out and let them leave. At this time, the Jin army camp was still waving flags on the surface, handsome flags were hung high, and soldiers were patrolling back and forth, and it was impossible to see that the camp was mostly empty at this moment.

Through the reconnaissance of the scouts, Zhao Yong judged that there were only 20,000 soldiers in the Jin army camp at this time, and the main force had already left for a day, and it was difficult for the two armies to support each other. Moreover, after 'observing' the offensive and defensive battles of the Goryeo Army and the Jin Army, the two generals already had an understanding of the tactics of the Jin Army, and conducted more than 10 days of targeted training and tactical drills, and were completely sure that they would destroy this unit.

On the twentieth day of the lunar month, Zhao Yong led two generals and a group of staff to climb the city tower to survey the terrain. The main road from Xijing to the north passes through the middle of the camp, dividing the camp into two halves, east and west. The terrain in the southwest is flat, and the terrain is undulating in the southeast near the Datong River, and the half-moon-shaped earthen city built by the Jin army separates the camp from the western capital. Form the first line of defense. Zhao Yongji planned to use the lion general to take on the task of attacking Tucheng and the big camp, and the predecessor of this army was the Xiangyi military lion battalion. After the expansion of the army in Taiyuan, he was called the leopard general, and participated in the battle of capturing Xiazhou, Fengzhou, Lingzhou and other fortified cities. Good at tackling tough problems.

The operational deployment was quickly determined: the lion would be divided into two divisions, with the 1st and 2nd brigades attacking the northeast corner of Tucheng, and the 3rd and 4th brigades attacking the southwest corner of Tucheng with the 5th and 6th brigades as reserves. After the battle began, the leopard general detoured back to the northwest of the camp to intercept the Jin army that had broken through, preventing them from escaping and joining the Chinese army. Because the earthen city was strong, it was difficult for the artillery to destroy it in a short time, so it was agreed that the sappers would deliver explosives to blow up the earthen ramparts, the artillery would fire at close to suppress and destroy the enemy trebuchet, and the covering lion would advance in depth.

In order to conceal the enemy. Reduce the killing and damage of trebuchets to the attacking troops and achieve the effect of surprise attacks, the time of the attack is chosen at the time of Yin, when the sky is not yet dawn and it is the coldest time, the enemy has not yet gotten up and has low vigilance, and it is inevitable that he will be in a hurry when he is attacked, so as to break through the earth barriers. And after the battle was in full swing, dawn was conducive to the artillerymen's discovery and aiming of targets and the subsequent battle for the battalion.

In the early morning of the 21st of the lunar month, the brigades participating in the attack quietly entered the attack area on foot from the east and west gates, and hid in two moats in the western capital city. The 3rd and 4th Brigades were responsible for attacking the southwest corner of Tucheng. The terrain is flat and there is little concealment, and the bright moonlight reflects on the snowy fields, which seem to be plated with a layer of silver. Dozens of steps away, you can see a swaying figure, and the figure of the Jin Army sentry on the corner tower of Tucheng is faintly visible.

"Sappers go, take cover!" The 3rd Brigade served as the main attacker. Commander Bao Gang set up the command post in a deep trench 200 paces away from Tucheng, and his breath was just settled. The sappers who were tasked with the demolition task were ordered to set off. The ability to blast the earth ramparts was the key to the smooth start of the battle, but it was very difficult to move to the bottom of the city on flat terrain. After pre-war reconnaissance, Zhang Pu found that a small winding river ditch in the southwest corner of Tucheng was connected to the moat, and now that the river is dry, it can be approached with its covert.

Although he couldn't see anything, Zhang Pu still stared at the dark earth city in front of him, although this was the coldest time, he still felt hot and sweaty in his palms. After the blasting, his soldiers will launch an attack on the earthen fortress, from the attack point to the city is a short 200 steps is the line of life and death, machine guns and artillery to the enemy hidden behind the earthen fortress is very limited, the soldiers can only brave the Jin army's arrow rain without any cover and effective cover, if the blasting fails, can not open the breakthrough, it will cause greater casualties.

"Has the demolition team set off?" The pre-war wait was the most difficult, Zhang Pu couldn't stay at the command post anymore, and went out to the forward command post of the Third Brigade, and as soon as he jumped in, he asked Bao Gangdao.

"It's already up, why are you here, it's too dangerous here!" Bao Gang was taken aback when he saw the comer.

"What nonsense, where is the assault battalion?" Zhang Pu reprimanded softly.

"Within fifty paces in front of the city, they set off first, and they have been lurking for two hours!" Bao Gang replied.

"What if the blasting fails?" Zhang Pu asked.

"Immediately organize a second blast, and the second echelon will build a ladder to attack the city!" Bao Gang replied.

"Well, as soon as the explosion sounds, immediately attack through the smoke, you must be fast, don't hesitate, immediately tear open the breakthrough!" Zhang Pu said, "If the blasting fails, the second echelon must go up quickly, prepare for the second blasting while attacking, don't wait, otherwise the casualties will be greater!" ”

"Rule, understood!" Bao Gang nodded and said......

The Jin army's earthen ramparts were unusually strong after being watered, and the machine guns could only leave a string of white spots on them, and even if the light artillery fired with solid shells, it could only smash down a few pieces of frozen soil. In order to ensure the success of the first blasting, the sappers prepared nearly 1,000 catties of gunpowder, and they had to send more than 20 packets of gunpowder to the city. After stealthily approaching, they used the shadows to approach slowly, and at this moment they were separated from the enemy only by a wall of earth, and the footsteps of the enemy patrol could be clearly heard.

Twenty fifty-pound explosives bags were silently sent to the earth barrier and piled up in the corner, Liu Er took out the fire fold in his arms, held it with his hand, and blew a breath, and the fire velvet immediately burst into flames. As an old sapper, he knows the power of this thousand catties of gunpowder explosion, even if he is swept away within thirty steps, he is missing arms and legs, and even his liver and gallbladder are cracked by the shock wave, and he only has a dozen minutes to escape, and he must escape as soon as possible, otherwise he will smash himself half to death if the clods of soil that fall from the sky and freeze like stones.

The flames of 'hiss......' swept on the fuse, and sparks immediately appeared, Liu Er immediately threw away the fire fold, turned around and jumped into the ditch and ran back without looking back.

"One, two, three...... Ten! Liu Er silently counted to ten in his heart while running, and a turn appeared in front of him, he immediately pounced back, covered his ears with his head in his hands and opened his mouth wide, and curled up his body tightly against the ditch wall.

'Boom' a loud noise, the strong flash of light made people subconsciously close their eyes and lower their heads, and a column of smoke that was twenty zhang high rushed up under the earthen barrier, Liu Er's body shook suddenly, he felt that his chest was stuffy, his stomach was churning, and he wanted to spit out all the things in his stomach, and there seemed to be thousands of bees flying around his ears.

"Collapsed!" Liu Er poked his head out to look at the blasting point, and under the powerful impact, the corner of the city disappeared, like a big mouth of a black hole in the night, and he shouted excitedly. But before he could take a closer look, a whirlwind swept the mud and snow against the ground, and as soon as he buried his head, the gravel and clods of earth fell like a hailstorm.

'Didi-ta-da... 'The trumpet of the charge sounded, and the assault battalion that was lying in ambush a hundred paces outside the earthen city immediately launched a charge. The soldiers, who had been lurking in the bitter cold for two hours, leaped to their feet, and their stiff hands and feet caused many to stand up and fall, and stubbornly get up and stumble forward.

"Quick, quick, quick......" The commander of the 3rd Brigade and 1st Battalion made Bordan pull up a fallen soldier and rush forward with a loud roar, they must rush into the city before the enemy reacts, consolidate and expand the breakthrough, open the way, and crush the enemy's archers, otherwise when the enemy reacts, a salvo will cause huge casualties to the charging troops, especially the trebuchet is the greatest threat to them.

The smoke of gunpowder has not yet dissipated, the assault battalion rushed in from the gap opened by the explosion, at this moment the frightened Jin soldiers have just come out of the nest of the ground, and before they have time to assemble, the patrols everywhere are rushing towards the gap, the scene is extremely chaotic, they did not expect that the Song army changed the usual way of fighting in the past, and did not carry out artillery preparations at all, but blew up the Tucheng in such a violent way to open a gap of more than ten zhang.

"Disperse enemy archers and take the high ground!" Bordan knew that in the darkness a single archer was blind, and that he could not threaten at all, and that if they formed a battle formation, it would cover a large area like a shotgun fired from artillery, and that if they dodged this arrow, they might have hit that arrow right on it. The assault team knocked out the Golden archers with a barrage of gunfire, and they fled alive, while the patrols that tried to plug the gap were quickly routed by machine gun fire.

The Song army divided into two teams to advance along the earth ramparts to the two flanks to expand the breach, while the sappers carried out several small blasts in succession, blasting gaps in the earth ramparts and opening more passages. The Jin army's counterattack was also very fast, the trebuchets began to fire stone projectiles in the direction of the breakthrough to prevent the follow-up troops from entering, and the cavalry quickly rushed out along the reserved passage, trying to drive the assault team out of the city and block the breakthrough.

"Hold the breach, concentrate fire, fire flares, and call for artillery support!" Bordan was taken aback when he saw the cavalry rushing up quickly, and hurriedly ordered the line to shrink.

The dispatch of cavalry was not staged during the attack of the Goryeo army, and the Song army also thought that in the earthen city with low walls and earthen fortresses, the movement of war horses was restricted and it was difficult to exert combat effectiveness, but who would have thought that the Jin army would ambush the cavalry behind the earthen fortress and reserve a passage, becoming an important counterattack force......
