The pace of the Great Song Dynasty's Western Expedition was very fast, and in just one month, it seized a large area of land in the Western Xia with lightning speed, and the three important state cities in the south of the Western Xia, Xiazhou, Longzhou, and Yinzhou were all occupied by the Great Song Dynasty.

These three state cities are simply the gateway to the south for Western Xia, not to mention the tendency of each other's horns, there are nearly 100,000 people in the Tibetan Department here alone, but obviously the party has miscalculated, these hundreds of thousands of Tibetan troops have been bought by various means of the Great Song Dynasty, or moved to the hinterland of the Great Song Dynasty, or became the army of the Great Song Dynasty.

The change of ownership of the land of the three states made the door of the Western Xia wide open at the same time, but also let the border of the Great Song Dynasty advance more than 100 miles, the Great Song Dynasty's border forbidden army began to advance after receiving the order, the Yongxing Military Road of the Dingbian Army, the Suide Army, the Security Army took over the defense of these state cities, occupied the geographical advantage to build city defense, the three states are each other's horns, plus the Great Song Dynasty has been operating for many years in Hongzhou, Yanzhou, these five states can be described as impregnable.

Completely different from the two armies of the East and West Routes, the South Route Army adopted the idea of steady and steady fighting, which was also the most suitable combat mode for the Great Song Dynasty, and the South Route Army represented the characteristics of the Great Song Dynasty army, mostly infantry, supplemented by powerful siege equipment and formations, and the siege of the city was naturally not a problem.

The artillery of the firearms battalion is their opening axe, and any strong city wall is shattered in front of them, plus the military formation of foot soldiers, it is difficult for the city of Western Xia to hold out for long in front of the Southern Route Army.

The appearance of artillery is something that breaks the balance of the battlefield, relatively, there are advantages and disadvantages, the artillery is heavy and abnormally inconvenient to move, and the artillery weighing hundreds of pounds or thousands of pounds cannot adapt to the speed of the cavalry at all, and can only be played most effectively in the infantry.

This big guy in the black hole seems to be amazingly powerful, but if he is used to deal with the cavalry troops of the Tanguts, it is simply self-defeating, and aiming at mobile targets is a big problem, not to mention the reloading time and other factors, if it is against large-scale infantry, it is still relatively effective.

The firearms brought by the firearms battalion this time are only artillery and gunpowder shells, even if Zhao Zhen insisted, Di Qing denied the function of the musket, in his eyes, the armor-piercing ability of the musket is still good, but relatively speaking, its cost is too high, although the range is as high as six hundred steps, which is twice that of the ratchet crossbow, but the speed of this musket is too slow......

This answer made Zhao Zhen a little speechless, yes, the speed of the musket is a little slower, but now the musket of the Great Song Dynasty has used a Migne warhead, and even a straight rifling has appeared in the barrel, the accuracy of this thing Zhao Zhen has tried, and it can maintain a fairly high accuracy within three hundred meters, and this kind of accuracy can't be done even by a ratchet crossbow, right?

But Di Qing still stubbornly vetoed, and gave a reasonable answer, when the two armies are fighting, the role of long-range forces is to fire as many crossbow arrows at the enemy in the shortest possible time, because at this time there is no need for precision at all......

Zhao Zhen was stupidly cried by his "little cleverness" in an instant, Di Qing was right, in the Great Song Dynasty...... No, in the whole history of China! All large-scale wars are 100,000, hundreds of thousands, or even millions of people, and such a huge scale will hit people even if the crossbow arrow is not enough, in the presence of a huge base.

The musket, a weapon with strong lethality and high accuracy, was not suitable for the needs of the Chinese War, which was something that Zhao Zhen would never have thought of, and his thinking was wrong from the beginning, and he was affected by later generations......

The Mine, which thought it was quite good, went in the wrong direction in the assumptions and premises from the beginning, and as a result, the Mingne rifle could only be eliminated from the battlefield, not because it was bad, but because it was too good......

In this way, Zhao Zhen's heart is also a little better, the main forces of the firearms battalion in the Great Song Dynasty will be invested in the development of artillery, although the musket is hidden, but Zhao Zhen does not plan to let go completely, because he has seen the horror of this thing, as long as he can improve his speed......

Zhao Zhen believes that through the accumulation of the times and the continuous improvement of technology, when the rear-loading musket comes out, it will inevitably become a replacement for the existence of crossbow arrows, of course, the musket will break the balance of war will definitely become the object of imitation by all countries.

But Zhao Zhen will never stop doing it because he is afraid of being imitated, even if he doesn't do it, with the development of history, sooner or later it will appear, is it possible that the Great Song Dynasty will not appear in other countries if he does not do it? This is obviously impossible.

What the Great Song Dynasty has to do is to keep the leading technology at all times, and maintain a strong national strength, as long as it stands at the forefront of the world, it will leave behind the international love that those who follow suit.

The powerful power of artillery has already made the Liao people salivate, and they continue to send secret spies to watch, but fortunately, the firearms battalion is an independent military system, directly under the jurisdiction of Zhao Zhen, and is only responsible for Zhao Zhen alone, so it is more difficult to steal the information of the artillery of the Great Song Dynasty than to ascend to the sky.

The great power and destructive power of artillery was truly reflected in the battlefield of Western Xia, and now the artillery power of the Great Song Firearms Battalion is enough to destroy the city walls of any country in the world, let alone Western Xia, even the fortified cities of the Liao Dynasty are not the opponents of the Great Song artillery.

The muzzle of the black hole emitted bursts of green smoke, this is the most advanced bronze artillery of the Great Song Dynasty, the bronze cannon is much better than the cast iron, at least it is not easy to burst, the cast iron technology of this era can not meet the needs of the artillery at all, the price of brass is too expensive, only bronze is the most suitable.

Even so, the casting cost of bronze artillery is expensive and frightening, and the technical difficulty is also quite large, even if it is quite rare to build more than 100 artillery pieces with the national strength of the Great Song Dynasty.

For the Liao people, artillery is not necessary at all, because they mainly use cavalry in the war, and mobility is the most important force for them.

After the artillery of the Liao Dynasty was blown up one after another, the Empress Dowager Liao decisively gave up this unrealistic thing, at least for the Liao Dynasty......

Today's Western Xia has been forced to the point of nowhere to retreat, the elite of the cavalry of the Great Song Dynasty does not lose to the Iron Harrier, and the damage of artillery to the city is far more terrible than the cavalry, the army of the Great Song Dynasty in order to accelerate the speed, constantly attack the city of the Western Xia people with artillery, and no city wall can withstand the bombardment of more than 100 artillery.

Today's Western Xia is already full of war, the military division of the east and west is contained by the Great Song Dynasty, and the military division in the south is also defeated and retreated again and again, but the north is not harassed, and the Liao Dynasty mobilized the military division of Baima Qiangzhen in the north and the military division of the right wing Chaoshun to come to support, this situation can really be described as the end of the road......
