At the same time that Li Yanqing took advantage of the weakness of Weicheng without strategic depth to easily capture Weicheng, Fengxiang Mansion in the south is also carrying out a tragic battle for Dasanguan, which is located at the northern foot of the Qinling Mountains in the southern suburbs of Baoji City today, and has been called "the throat of Sichuan and Shaanxi" since ancient times.

But for the Western Xia army, Dasanguan had a second important significance, they wanted to attack Li Yanqing's backyard and force Li Yanqing to withdraw from Western Xia, and the purpose of both sides was the same, hoping that the other side would be forced to withdraw from their respective territories.

Of course, the Western Xia army has another choice, the army directly kills to Douling and Niuling, captures the Hulu River Valley, and cuts off Li Yanqing's back road, but this road to the north is too difficult, to cross the reckless Liupan Mountains, even if the soldiers can climb the mountains and cross the mountains, but the logistics baggage is not at all passable, not only that, the Song army also deployed thousands of defenders on the dangerous passes, if the forced north attack, tens of thousands of troops will be trapped in the reckless mountains.

Richard was very aware of this, and he gave up his plan to attack Hulu Valley from the west, and instead adopted a more realistic plan, capturing the Dasan Pass, and the army entered the pass, forcing Li Yanqing's army to retreat.

Dasanguan by the famous general of the Western Army Liu Tao led 10,000 troops to sit in the town, Liu Tao was originally appointed as the Qinfeng Road Economic Envoy, when Li Yanqing served as the Northwest Three Roads Economic Strategy Envoy, Jingzhao stayed behind, and the Western Army was under control, Liu Tao was reappointed as Taiyuan Mansion Yin, Hedong Road pacification envoy, but he was temporarily unable to take office, Hedong Road is still in the hands of Jin Guo, and he also needs to lead the army to recover, at the same time, the situation of Qinfeng Road is critical, Li Yanqing asked him to continue to sit in Dasanguan, until the situation stabilizes and then hand over the handover of Shuaiyin.

Not only that, Li Yanqing also sent Liu Tie to lead 3,000 troops to Dasanguan to help in the battle, although there were not many reinforcements, but they brought the most advanced weapons to defend the city, the nemesis of the siege ladder - Flying Fire Thunder.

'Boom! Boom! Boom! The drums outside the Dasan Pass shook the sky, and 30,000 soldiers of the Western Xia Army slaughtered the city like a tide, which was the third siege battle launched by Richard Brother.

The Dasanguan is on higher ground, and the city is made of huge stones, which is extremely tall and strong, and the Western Xia army attacked from a low place, which was more difficult, and they had to use a large siege ladder four zhang long, which was four feet wide, and the ladder beams on both sides were as thick as a calf, and were made of fine and solid ash wood.

30,000 Western Xia soldiers carrying hundreds of large siege ladders surging towards the city to kill, on the city pass, thousands of soldiers holding big bows in their hands are waiting for the battle, dozens of small trebuchets are also creaking and rattling, the Western army does not have almost no sharp firearms such as earth-shaking thunder, the imperial court did not expect that the Xixia army will attack Xihe Road in a big way, and all the hundreds of earth-shaking thunders in Jingzhao Mansion and Fengxiang Mansion were transferred to Taiyuan and Tokyo.

There are dozens of catties of boulders in the trebuchet on the head of the city, this kind of small trebuchet throwing rod is only one zhang, can throw thirty or forty catties of boulders to a hundred steps away, but Liu Tie's arrival changed the disadvantage of the weak defensive weapons of Dasanguan, they not only brought a thousand flying fire mines, but also brought fifty earth-shaking thunder, which greatly strengthened the defense ability of Dasanguan.

At this time, twenty sky-shaking thunderbolts had already been put into the pocket of the small trebuchet, Liu Tao looked at the surging Western Xia soldiers under the city, the Western Xia soldiers had already entered within one hundred and fifty steps, and he immediately shouted: "Crossbow arrows fire!" ”

The red flag waved, a thousand divine arm crossbows were the first to be launched, their killing distance was between one hundred and fifty steps to one hundred and eighty steps, most of the Western Xia soldiers wore leather armor, held spears, and did not have a shield to guard, only the sword and shield army had a solid shield, after all, the Western Xia was only a small country, the national strength was relatively poor, and it was impossible to be fully equipped like the Song army, even if the Song army, only the forbidden army was equipped with shields, and the ordinary box army and township soldiers were not equipped.

A thousand crossbow arrows were fired intensively at the surging enemy army, and the soldiers who rushed in front immediately fell down one after another, with hundreds of casualties, but the casualties of hundreds of people were just a wave in the ocean for the 30,000 army, and it had no meaning, and the Western Xia army continued to rush towards Guancheng.

After two rounds of strong crossbow firing, the 5,000 Western Xia crossbowmen who were at the forefront finally came within a hundred paces.

Seeing that the enemy had entered the range of the trebuchet, Liu Tao calmly ordered: "Trebuchet shooting!" ”

The green flag waved over the city, and the trebuchet, which had been accumulating for a long time, was activated, and the soldiers lit the arquebus, and with a series of 'bang! Boom! With the sound of throwing, twenty swarthy sky-shattering thunderbolts rose into the air and smashed towards the heads of the Western Xia soldiers who were a hundred paces away.

The Western Xia soldiers obviously did not have systematic training to avoid bombing, they did not know that prostrate and shields could protect themselves from being injured by explosions to the greatest extent, and they did not have special mine-watching soldiers.

Twenty earth-shattering thunderbolts exploded on the two-mile-wide field, the explosion was earth-shattering, the smoke was filled, the screams and cries on the field were everywhere, and the soldiers who were directly killed by the explosion alone amounted to thousands, and the soldiers who were unfortunately injured by the flying shrapnel were several times as many as the soldiers were killed.

A sky-shaking thunder can be split into hundreds of iron fragments, including the shell itself and the iron particles filled inside, shrapnel and iron particles fly, a large number of Western Xia soldiers were hit and fell, a round of earth-shaking thunder explosion, the number of casualties exceeded three thousand, and the Western Xia soldiers were really a little frightened.

Brother Richard was anxious, the Western Xia army had already entered within a hundred steps, and it must not retreat again, no matter how many casualties there were, it must continue to fight hard, he shouted loudly: "Continue to attack, those who retreat will be killed immediately!" ”

'Boom! Boom! Boom! Boom! The fierce war drums sounded, tens of thousands of Western Xia soldiers could not retreat, they could only continue to charge, three thousand crossbowmen took the lead to run to the city, began to release arrows to the city, dense arrows shot to the head of the city, suppressed the shot of the crossbow soldiers, but three thousand big bow soldiers stood behind, shooting down in the form of projectiles, thick arrows fell like raindrops, the Western Xia soldiers were difficult to dodge, they were hit by arrows, or killed or wounded, the losses were very heavy, the Western Xia crossbowmen were suppressed again, and the remaining crossbowmen had to retreat.

At the same time, the second round of earth-shattering thunder was launched, and huge explosions rose one after another in the crowd, and soldiers were constantly blown up into the sky, and the battlefield was filled with gunsmoke, minced flesh flew sideways, blood droplets were splashed, and the death of the soldiers who were killed by the explosion was extremely tragic.

Seeing that the attacking soldiers had retreated, Richard immediately ordered five hundred swords and axes to press forward and kill all the retreating soldiers, and after hundreds of soldiers were killed, the Western Xia soldiers attacked again, and more than 10,000 soldiers rushed to the city and put a large siege ladder on the head of the city.

Liu Tie led five hundred throwers to dispatch, they are specialized flying fire and thunder throwing soldiers, the throwing skills are very skilled, they lit a very short fire rope, the copper stick was thrown out immediately, and the two flying fire thunders that were pulled by the slender iron chain immediately circled and flew towards the siege ladder, 'Boom! The iron chain was blocked by the ladder beam, and immediately flew left and right, and the flying fire and thunder tightly entangled the siege ladder, and then boom! Rumble! There were two explosions, and the siege ladder was blown off by the barricade.

Not only a siege ladder, but also hundreds of siege ladders that had just taken the head of the city all suffered the consequences of being blown up by the waist, and the Song army immediately poured fire oil on the siege ladder and lit it with a fire breaker, and the fire quickly engulfed more than 100 large siege ladders, and the Western Xia soldiers were stunned, they could no longer attack the city, so they had to retreat one after another.

In the distance, Brother Richard could see clearly that more than 100 siege ladders had become strings of fire, so he had to sigh secretly and order: "Pass my order, the whole army retreats!" ”

'When! While! While! The bell for the withdrawal rang, and the soldiers, who had already lost their morale, retreated like a receding tide.

The soldiers at the head of the city suddenly burst into excited cheers.

In this offensive and defensive battle, the Western Xia army suffered nearly 10,000 casualties, but the Dasanguan was not damaged at all, and only more than 40 people in the defenders of the city were wounded by arrows, and no one was killed.

Richard also knew that he could no longer capture Dasanguan, so he had to lead a large army to retreat in the direction of Huizhou.
