In the Battle of Hanzhong, the attack and defense before Chang'an Ying Dazhai intensified, and Cao Hong, the general of the Cao army, even personally led the elite of the Flying Bear Army to launch an attack, using its strong combat power to resist the Yan army's repeated short assault methods. Xiahoudun and Cao Hong's focus is still extremely accurate, and the strong general's strength did have an immediate effect, after all, under the continuous impact of Cao's army's superior forces, Zhang Xiu is through a variety of tactics to protect Dazhai without losing the physical strength of the soldiers, but the physical consumption of the soldiers is huge, from day to night, this offensive and defensive battle has lasted for seven hours, and the high-intensity continuous combat makes every Yan soldier inevitably tired. In particular, there are already many cramps in the army of crossbowmen and equipment battalions operating the sky-bombing cannons!

However, even so, the Yan army still united to block this round of crazy offensive of the Cao army, and the Cao army's ace Flying Bear Army was also greatly damaged, and the key role played in this was Pang De Pang Lingming, the deputy commander of the Sizhou battalion, who not only personally defeated Cao Zilian, the fierce general of the Cao battalion, but also turned the disadvantaged battle situation around with the strength of one person. Pang Lingming's courage is also known to the world in the future!

In the bloody battle of Lianshan in the battle of Jizhou that day, Liu Yi took the lead in the charge and killed more than 500 soldiers in Jizhou with the strength of one person, so that the advantage and disadvantage of the situation were reversed, and the defense of the Youzhou army became more and more stable, but at that time, although the soldiers under Yuan Shao were numerous, they were not as dominant as the Cao army in Hanzhong today, and the Cao army of this time was as many as 300,000, and Xiahoudun led 60,000 soldiers to divide into ten teams to constantly impact the Dazhai guarded by Zhang Xiu, but the strength of the Chang'an battalion here was only 10,000. To be able to hold on to this day is to rely on the excellent performance of the equipment battalion and the practical use of various exquisite tactics, but after all, these can not fundamentally change the situation, Pang De's courage can only be used for a while, and then after an hour of attack and defense, when the day is red, the first gate of Dazhai has been broken through by the desperate Cao army, and the next is the real short-handed encounter!

Knowing that the Cao army is fierce, Zhang Xiu spent a lot of thought on the village, this situation is also in his preparations, the difference between the strength of the enemy and me is too great, and the general order given by the military division is not to defend but to hit the morale of the Cao army to the greatest extent, so in the village Zhang Xiu also ordered his corporal to dig several trenches as deep as one zhang, which was intended to hinder the Cao army that broke through the camp, and it turned out that Zhang Gongxing's method of resistance played a great role in the actual combat. Those trenches were extremely effective in blocking the speed of Cao's army's march and allowing the Chang'an battalion to have enough time to arrange the next step of defense, which can be said to have paid a lot of price for each step!

The existence of the equipment battalion is by no means only used in the specific battle between attack and defense, and the bombardment cannon and the rushing car well fence are not used to operate with 5,000 soldiers, as an innovative auxiliary force, there are still many effects that the rest of the princes do not know well! For example, thousands of miles away, the Juyi Flame Army encountered the Vortex River blocking the road in the process of advancing into Lu County, and it was the equipment battalion that came out to build the pontoon bridge.

Of course, this is Liu Yi's innovation in the two-year strategy of the existing arms, in the later era, whether the defensive position of an army is built is perfect is an important embodiment of its combat effectiveness, and in which the engineer plays a very key role, in the face of the enemy's fierce artillery fire and bombardment, whether the position can stand the test will determine the success or failure of the defensive war! The concept of the position in the Cold Weapon Era is not as prominent as that of later generations, but this does not mean that the sappers have no value in existence, on the contrary, the generals are all very in favor of it after listening to the idea of King Yan!

In many cases, what innovation and improvement lack is not the conditions and means, but the idea of the outline of the inspiration, in the Yan army there is Liu Yi will not lack such an idea, of course, the experience of later generations may not be applicable to today, but the power of group wisdom can not be ignored, what is the real scientific point of view? Make bold assumptions and be careful to verify! These eight words and the states of Youzhou have been fully reflected in the fields of military and people's livelihood. Many of Liu Yi's ideas are also put into practice after countless practices under the efforts of others, of course, there are inevitably examples of failure, but success can have immediate results!

In the two years of military training, in addition to the most basic training, almost all the drills of the equipment battalion are self-contained, and even for their comrades to maintain a certain degree of mystery, Liu Yi is also extremely cautious in the selection of the captain of the equipment battalion, he has always been the point of view that professionals are used in the professional field, since as an auxiliary army, cooperating with the main force is the most important responsibility of the equipment battalion, and here Langsheng is also bold to use newcomers, After all, in the acceptance of these new knowledge, after all, young people have incomparable advantages and momentum, like the captain Yi Chenglong in the Chang'an battalion is only nineteen this year, he does not have rich experience in battle formations and extraordinary martial arts, but after this battle, who dares to underestimate him, at this moment the Chang'an battalion brought almost half of the casualties to the Cao army are from the hands of the equipment battalion, they are the nightmare of the enemy!

Those trenches in the village are filled with withered grass, and when the Cao army passes through it, the thunderbolt canister fired by the cannons has become the soul talisman of the Cao soldiers, often under a salvo, the entire trench is a sea of fire, and many soldiers are burned by the flames and struggle to make a scream that is not like a human being! And the comrades in front of them are powerless, maybe judging from the number of kills, hundreds of thousands of casualties are just a drop in the bucket for hundreds of thousands of Cao troops, but such a miserable scene is an extremely deep blow to the morale of their troops, they don't know how many novel tactics are waiting for the Yan army ahead, even the most determined people should be unbearable in the long run!

After breaking through the two trenches of the Chang'an battalion, Xiahoudun had to order a temporary postponement of the attack and a little rectification, not that he didn't want to take all the positions of the Chang'an battalion in one go, and he would not care too much about the casualties of the soldiers at this time, but this battle was just an outpost of the Hanzhong War, and the morale of the army would be the key to his consideration, and he must not let his subordinates be afraid of the Yan army in this battle, so that even if he could repel Zhang Xiu's department, it would be worth the loss. In addition, he had not seen each other for several years, and the battle of Jia Meng Pass made him see the powerful combat power of the Yan army that he had not seen for a long time, and the skillful use of its tactics and the sophistication of the equipment in this offensive and defensive battle had exceeded his expectations!

Cao Jun's offensive was suspended, Zhang Xiu also seized this rare opportunity to rest the soldiers, a day and a night of sleepless rest for the elite of the Yan Army is commonplace, but this day and night is by no means an ordinary exercise, but an extremely cruel actual combat, in the face of all kinds of surprise when the Cao Army showed the kind of composure and fearlessness is Zhang Xiu Pang De Ma Dai and others are also admired in their hearts, it seems that they gave the other party a huge loss in this battle, but after this battle Cao Jun also has a deeper understanding of the Yan Army after two years of strategy, After that, there will definitely be a targeted tactic soon, and when the two armies face each other, the advantage of the Yan army will not be so huge!

Just when the two sides were resting, Zhang Xiu received a letter from Zhang Hu, asking him to lead the army back and join the main force, Ma Chao's Sizhou battalion will provide guarantee for the retreat of the Chang'an battalion, and the military division will not dare to disobey the public line, and will do it immediately! Xiahoudun also had to occupy the Yan army Dazhai because of this, and after the count, the Cao army suffered as many as 20,000 casualties in this battle alone, and the Cao army did not have such damage when Zhang Ren Yanyan's elite Shuzhong decisive battle, but this was only the first battle in Hanzhong!
