Due to the solution of the road problem, the Sichuan army quickly approached the pass, since the pass is named after the pass, it shows that the terrain here is dangerous, easy to defend and difficult to attack, and the Dian army invested nearly 3,000 elite soldiers of Zhao Youxin's department here.

Qiao Yu, Jiang Baili and all the senior officers were sitting in front of the huge military map, and Jiang Baili was explaining the deployment of the Dian army to everyone.

"Ladies and gentlemen, the terrain of Daguan can be summarized as high mountains, steep slopes, dense forests, rapids, ravines and ravines, this kind of terrain is extremely beneficial to the defending side of the Yunnan army, Zhao Youxin has put a lot of effort into the defense, with three highlands as the core of the fortifications, trenches are all over, and some barbed wire fences are arranged outside, and Zhao Youxin's department is very well-equipped, there are a large number of artillery and machine guns, according to the danger to defend, it can be described as easy to defend and difficult to attack, and our army must quickly take the pass, Otherwise, the soldiers of Zhaotong and Luo Peijin's brigade will soon be able to assist Zhao Youxin! ”

After Jiang Baili finished speaking, Qiao Yu glanced at everyone again, "Everyone, it has been cloudy in the past few days, and the fog is relatively large, so the air force has been greatly restricted, everyone must be ready to fight a tough battle, and must quickly capture the pass, this time the main attack task is the third division of Shiyi, and Wang Zhanxu's department is used as a support force!" ”

"Yes!" Shi Yi and Wang Zhanxu saluted together, and it can be said that it is a huge trust to be able to hand over the task of attacking the fortification to them this time, and both of them hurriedly went to prepare.

At dawn, the mountains were filled with fog, and the offensive of the Sichuan army began, because it was impossible to dispatch the aircraft, the protagonist became the god of war artillery, due to the problem of transportation, the 155 mm howitzer was not transported, and now there are only four 120 mm cannons in Shi Yi's hands, and the rest are all 75 mm caliber artillery, but this level of artillery is enough, and the maximum caliber of the opposite Yunnan army is 105 mm mountain artillery.

Moreover, this kind of mountain artillery is still imported from Sichuan, although the caliber is not small, but it is a pity that the firing range of this light mountain artillery is only six thousand meters, which is less than half of the cannon of the Sichuan army, and even the seventy-five mm Krupp gun can be superior in range, and the only commendable thing about this kind of artillery is that it is light enough and easy to transport.

But in this kind of bombardment, the weakness is exposed, the Sichuan army in order to attack the pass concentrated sixty artillery, the black hole of the cannon is facing the position of the Yunnan army, as if a giant beast, open the mouth of blood, waiting to devour the living beings, after everything is ready, the Sichuan artillery frantically tilted the shells to the position of the Yunnan army, the earth shook in the sound of artillery, the sky was covered by gunsmoke, large pieces of soil were bombarded into the air, the position of the Yunnan army seemed to be a rag half, Under the heavy punch of the Sichuan army, he reluctantly changed his shape.

Zhao Youxin was also frightened at this time, in this round of shelling, hundreds of soldiers of the Yunnan army had been killed, and the artillery of the Yunnan army occasionally returned fire a few times, but immediately attracted the key care of the Sichuan artillery, and soon blew up the precious and abnormal cannon into parts, so the Yunnan army could only be beaten passively, and did not dare to bombard the Sichuan army again.

Although the situation is very critical, Zhao Youxin still maintains basic composure, after all, he has been operating in Daguan for a long time, the position is very strong, there are many fortifications, and God seems to be on his side, now the fog is thick, and the most deterrent air force of the Sichuan army cannot participate in the war, so Zhao Youxin is relieved a lot, and the Yunnan army really has no weapon to resist the air force now.

After the artillery attack, the Sichuan soldiers began to attack the position of the Yunnan army, and countless Sichuan soldiers formed a gray wave, rushing towards the position of the Yunnan army in strict accordance with the formation of the three-three system.

All the soldiers were extremely calm, relying on this strong fortification, and began to shoot at the Sichuan army, there were also many sharpshooters in the Dian army, and the Sichuan army that charged at the forefront was hit by a bullet fired head-on, and suddenly the skull was torn apart, like a broken watermelon, blood and brains were everywhere, the body of the young soldier had not fallen immediately, the camera seemed to be frozen, and the smell of blood in the air was much stronger.

The other soldiers didn't bother with this partner at all, and on this battlefield they quickly broke away from their immaturity and began to become a real warrior, and became indifferent, this indifference was not a perverted beast, but an instinctive pursuit of efficiency on the battlefield, they knew how to achieve the greatest victory with the least casualties, and they still bent over to avoid being hit by bullets.

There is also a barbed wire fence in front of them, Qiao Yu focused his attention on Europe, even many Chinese in this era are more concerned about the situation in the European battlefield, Cai Gong is one of them, after he knew the important surname of barbed wire, he prepared a lot of defense, this time a barbed wire fence was pulled around the periphery of the Daguan position, which brought great trouble to the Sichuan army's attack.

However, the Sichuan army was prepared, they first threw more than a dozen grenades together, blew up the barbed wire, and then sapped the sappers to split the remaining barbed wire, the whole process did not take much time.

After crossing the barbed wire fence and crossing a ravine, the Sichuan army soon got closer and closer to the position of the Yunnan army, and at this time, the light and heavy machine guns of the Yunnan army also opened fire, and the dense rain of bullets covered it, as fierce as the autumn wind sweeping away the leaves.

Suddenly, more than a dozen Sichuan soldiers fell on the way to charge, at this time the Sichuan soldiers no longer simply charged, but covered each other, and began to suppress the position of the Yunnan army, at this time the grenadier became the most powerful weapon again, and one grenade was fired quickly to the position of the Yunnan army.

More than 20 grenades were fired every minute, and one by one the grenades burst out in the position of the Dian army, like a brilliant fireworks, but this fireworks burned life, so it looked more bewitching and moving, all the soldiers were dominated by something called adrenaline, forgetting fatigue, forgetting fear, and only focusing on the enemy's position!

The battle situation was very fierce from the beginning, Zhao Youxin couldn't sit still at first, he was entrusted by Cai Yi, and he knew very well that Cai Yi valued this Sichuan-Yunnan portal, Cai Yi also knew that the Yunnan army could not stop the Sichuan army, but it was necessary to delay time, Cai Yi gave Zhao Youxin a minimum requirement of ten days, and he must be nailed to Daguan for ten days like a nail, so as to gain time for the further mobilization of the Yunnan army.

"Where is the artillery, hurry up and bombard the Sichuan army for me, bombard!" A Sichuan army soldier had already approached the position of the Dian army, and Zhao Youxin could no longer care about anything, and hurriedly urged the artillery to attack.

The artillery of the Dian army finally started again, and four shells fell in the ranks of the charging Sichuan army, and the shells burst, destroying all the creatures within ten meters around, and the original charging formation seemed to be suddenly taken away, and the Sichuan army had to quickly retreat.

The artillery of the Yunnan army was aimed at another place, but before they could fire, the artillery of the Sichuan army had already calculated their position, dozens of kilograms of shells hit head-on, the killing range of the Sichuan army's 120 mm cannon almost reached a radius of thirty meters, the violent explosion of the shells seemed to be a muffled thunder falling to the ground, and the violent air waves sent all the artillery of the Yunnan army into the air, and most of them had been turned into a sieve by a single piece before flying into the sky, Others did not have serious external injuries, but the violent explosion had shattered all their internal organs and turned them into a pot of porridge.

** It is fragile in front of the shells, and the artillery is still like this, the two mountain guns have all become parts and are scattered all over the ground, fortunately, there are no shells around, otherwise the losses of the Dian army will be greater after the explosion.

Zhao Youxin's face is blue, the Sichuan army is really not a thing, the equipment provided by the Dian army is a useless thing, one hundred and five mm mountain artillery, except for the good caliber, the whole thing is a tragedy, but now what's worse is that even this tragedy is about to be consumed.

At this time, the first line of defense has been shaken in several places, the soldiers of the Sichuan army have rushed to the trenches, and now the two armies are fighting bayonets, the nutritional conditions of the soldiers of the Sichuan army are generally better than those of the Yunnan army, tall and tall, the strength is sufficient, and the cooperation is also in place, since the last time the Sichuan army and the Yunnan army were in battle, after suffering a loss in the bayonet, the Sichuan army has made great efforts, specially hired a group of martial arts instructors, and extracted the most concise and effective moves from many martial arts routines to fight bayonets, After hard training, the Sichuan army's ability to fight in white knuckle warfare rapidly improved.

In addition to the bayonet, the Sichuan army also has another big weapon, that is, the sapper shovel, don't underestimate this thing, it is simply a versatile treasure, it can be used as a shovel, it can also be used as a hammer, it can cut wood, it can also cut potatoes, it can also be used as a flying chain chain, and it is unambiguous to cut people's heads.

The Sichuan army, which was holding back revenge, was having a good time this time, and most of the thin Dian army soon fell to the ground, and the rest fled in disarray, and the forward positions changed hands, but the next battle became more difficult, and the Dian army built a second layer of defense with three highlands as the core.

The highest relative height of these three highlands reached 270 meters, and there was a slope of more than 45 degrees head-on, and there was a river outside the slope to block it, forming an extremely favorable terrain for the Dian army.

Shi Yi saw that the Sichuan army was facing a large number of casualties on the high ground, and knew that he could no longer make this kind of sacrifice in vain, so he had to let the army temporarily stop attacking, and the most advantageous weapon to deal with this danger was the air force.

The first batch had a total of four planes, hanging eight 100-kilogram bombs, and the Yunnan army did not have any air defense equipment, so the Sichuan air force appeared very relaxed, flew over the high ground, and all eight bombs were dropped!
