Sun Tzu said, 'Ten are surrounded, five are attacked, and multiple are divided.' 'A successful campaign is one in which the shortest possible time and with the least casualties and losses can be won. According to the number of your own troops exceeding the enemy's number, you should adopt different strategies and tactics accordingly, avoid hard fighting, and exchange the greatest victory for the least cost.

This viewpoint is based on pragmatism, with the pursuit of victory in war as the ultimate goal, and the achievement of greater victory at the lowest cost is even more pragmatic. Victory is the goal of all strategy, and the role of strategy should be to minimize the cost of victory, not to make the war wonderful. The battlefield should not be a show of the personal talents of military commanders, and even more so a game, neither fun nor should be played ...

The left-wing Song army led by Yue Fei surpassed the brigade and arrived at the Qigou Pass first, seeing that the Jin army could not come out of the retreat, thinking that the Guanzhong was just a defeated Jin army and did not dare to fight, so he wanted to take the pass in one go and make the first contribution. Under Yue Fei's strict training, the Zhongshan Luzhou Army had become a strong force, and immediately launched an attack in formation after receiving the order, but they made a big mistake, did not conduct careful reconnaissance before the battle, and knew nothing about the strength and fortification of Qigou Pass.

The Zhongshan Luzhou Army in this battle has a total of 20,000 horse infantry troops, equipped with bows, crossbows, knives and guns These cold weapons, and the Jin Army in Qigou Pass is a strange and full team of 10,000 people in the Pingzhou Army, plus some of the defeated remnants of the army that can be collected by Yinshu, although the strength is slightly inferior to the Zhongshan Zhou Army, but they occupy the strong city, and there is Yinshu can be commanded by this general, and the Song Army's strength advantage can be ignored.

During the negotiations, the generals of the Jin army had previously judged that the border between the Chen soldiers of the Southern Dynasty was nothing more than an intimidation of the Jin state. If you want to make some gains in the negotiations, even if you fight, it will only be a small fight. No Forbidden Army will be dispatched to start a full-scale war. Based on this prediction, even if the Song army attacked. As long as you hold Qigou Pass, you can buy time for Yanjing to send reinforcements.

Yinshu is a fierce general but not reckless, after Xiongzhou received the Southern Dynasty war letter, the shock can be imagined, the Southern Dynasty is going to really fight, but he did not expect the Song army to attack so quickly, when he heard the fierce artillery sound on the border, he knew that the Southern Dynasty sent a forbidden army, and these garrisons on the border could not resist at all. So the cannon rang out. He retreated to Qigou Pass, intending to use the fortified city to block the enemy and wait for reinforcements.

Yinshu can return to Qigou Pass and immediately ask for help from Yanjing, and reorganize the army to fight, he and the predecessor of the Song Dynasty forbidden army' Xijing Army' fought several times, knowing the horror of their firearms, so he strictly ordered the defenders in the city to hold on, not out of the city to fight, which also led to Yue Fei's miscalculation, thinking that the Jin army was lacking in strength. Cowardice.

With similar equipment and similar troops, the Song army besieging the city quickly paid the price, and several attacks were fruitless. and lost his troops, Yue Fei was in a hurry, and personally led the army to attack the city. And Yinshuke also quickly discovered that the Song army besieging the city was not the main forbidden army. Immediately had the feeling that the tiger was falling in Pingyang and being bullied by dogs, and he sent an army to attack the Song army that was attacking the city from the side gate. I want to teach these self-righteous Song Jun a lesson.

The Song army, which was attacking the city with all its might, paid a lot of casualties before barely crossing the moat and erecting a ladder, and the Jin army that attacked on the side was killed. caused a panic, and the frontal Jin army also opened the city gate and killed. Fortunately, the troops were well-trained and disciplined, and there was no rout under the assault of the Jin army, Yue Fei led the front army to retreat while fighting, and the brigade that was attacked by the flank was also under the leadership of Niu Gao, the commander of the Chinese army, and did not retreat, and received the front army to return to the battle.

After a hard battle, Yue Fei retreated to his own position, and at this moment he also realized that the Jin army in the pass was by no means a defeated army, and with his own strength, in order to avoid further losses, he decisively retreated across the river to form a defense. And Yinshuke was also worried that the Song army was deceitful and buried an ambush, so when he saw that it was good, he would no longer pursue, and ordered the Jin army to retreat into the city...

Yue Fei lost the first battle, lost hundreds of soldiers, retreated ten miles and joined the army, and ordered someone to tie himself up to the commander's tent to ask for guilt. It is a felony not to obey the general's orders, to make meritorious contributions, and to cause losses, but for Yue Fei's defeat, Zhao Yong did not punish him, but personally went to the Zhongshan Luzhou military camp to comfort him with kind words and encourage the soldiers to fight again.

This incentive was immediate, and the next night, Yue Fei led the army to occupy the Jin army's supply center in Suiwu with only one surprise attack, and this small victory made a lot of oil and water, and also obtained information from the captured prisoners that Wanyan Zongfu had sent troops to help. When Zhao Yong learned of this, he immediately ordered the siege of the city, and took Qigou Pass before the Jin army reinforcements arrived, opening the passage for the march. Before the war began, the Song army had already taken the lead...

Qigou checkpoint on the march road, must be taken as soon as possible, after some reconnaissance, Zhao Yong figured out the situation inside and outside the pass, the guard general Yinshu is also his old opponent, the two in the northwest several times are defeated and returned, his brother is still in the Great Song Dynasty 'guest'! In the early morning of the next day, Zhao Yong ordered the tiger general to attack the city, Yue Fei wanted the shame of the defeat of the bloody army, and also asked to fight together, Zhao Yong thought about it and agreed.

Seeing the Song army brigade coming, Yinshu can see the flag, embroidered with a tiger with long wings, and know that the Song Dynasty forbidden army has arrived, as for whether the handsome flag is seen or not, it is 'Zhao', their emperor's surname is Zhao, and the generals who can fight under them are also surnamed Zhao, as for which one is not much different. He has been beaten so many times and summed up some experience, when the strength is superior, he can still fight, when the number of people is small, find a strong place to hide, and when they approach, the power of the artillery can not be exerted.

Therefore, Yinshu could see that the Song army's team could not see the edge, and immediately pretended to be a turtle and closed the four doors, putting on a posture that could not be killed, let alone attack halfway. He was familiar with the tactics of the Song army, and when attacking the city, the artillery opened the way and the machine gun covered. In order to avoid artillery fire, he ambushed most of his troops under the city wall, leaving only a small number of troops in the city to observe the movements of the Song army. In view of the Song army's penchant for blowing up the city gate, he also took effective measures to block the east, south, and west gates with boulders, leaving the north gate alone.

Seeing that the Song army successfully crossed the Qigou River, it was indeed as expected by Yinshu to line up two arrows away from the south gate, and the cannon was pushed to the front of the formation and began a round of tight shelling, the machine gun blocked the battlement, a group of Song troops pushed the bridge cart out of the formation, and set up several pontoon bridges on the moat, and then there was a muffled sound under the city gate. Hiding under the root of the city, the silver art can dig out the ears that shook the 'buzzing' sound and laughed, always take the old trick of fooling people, you toss for a long time, Lao Tzu is not hurt!

"Dutong, the Song army failed to blow up the city gate...", a Jin general who was monitoring the movements of the Song army at the head of the city ran down the city to report in disgrace.

"Isn't it annoyed and angry, rushing up with a ladder, ready to go to the city!" Yinshu didn't wait for him to finish speaking, and said proudly.

"Dutong, no, it's Song Jun and..."General Jin hurriedly waved his hand.

"Retreat?!" Yinshuke stood up and shouted in surprise, but there was a loud noise outside the city, he was stunned for a moment, and suddenly felt a shock under his feet, and in a trance it seemed that the city walls were shaking, but soon he found that it was not his own illusion, the soil on the city wall fell in a torrent, and some soldiers rolled down from the city screaming.

"What's going on?" Yinshu Ke was furious, and turned his face and yelled at the golden general who came to report it.

"Dutong, the Song army has launched two giant artillery!" This Jin Jiang finally said the second half of the sentence...

Seeing that the sappers failed to succeed in blasting, the tiger general commanded the army of Wang Hengjin of Zhilu Dao must have blocked the city gate, and in this case, the only way to deal with this kind of fortified city was to prepare for a strong attack, just when he was about to transfer troops to prepare siege equipment to enter the city, Zhao Yong stopped him.

When Zhao Ta attacked Lingzhou, he realized that the power of the fast-fire cannon and mortar cannon equipped with the Buddha machine was not enough to deal with the well-fortified fortified city, and he knew that with the southward expansion of the Jin State, he would inevitably absorb the military strategy, offensive and defensive tactics of the Central Plains region in the invasion, and manufacture advanced equipment and city building methods. In that future battle, it will be difficult to be competent with the current weapons and equipment, especially a big city like Lingzhou. At that time, people began to try to produce siege artillery, but in this era, it was very difficult to cast artillery more than 1,000 catties.

It was not until the third Jin army invasion that the workshop successfully trial-produced a few jacks of artillery, and then hastily formed a heavy artillery battalion to prepare for the capture of Bianjing, but it has not been used. After ascending the throne, Zhao Ta mastered the country's material and financial resources, increased the intensity of artillery research and development, and finally succeeded in trial production, the gun body was cast in bronze weighing 8,000 catties, think about not counting the manual cost, the caliber is eight inches, the solid iron bullet fired has a big head, and the charge has to be 20 catties, but it is also a lot of money, just the copper consumed can cast how many copper coins, not counting this cannon has to be served by all soldiers.

This cannon may not be anything in front of today's hundreds of tons of cannons, but in this era it is a giant, but it is not without shortcomings, it is long in siege and can fire a variety of ammunition, but it is clumsy in field warfare, using a breech charge, resulting in a low rate of loading and firing, and the cannon body is bulky, unable to quickly transfer positions, and can only be bombarded at fixed points. When the situation of the enemy and the enemy is reversed, it is impossible to maneuver and react, and without the cooperation and protection of the infantry cavalry, it is not enough to win the battle.

It was precisely because of the fact that this thing was too bulky that Zhao Ta did not bring these two siege guns with him when he attacked Yanjing City this time, but left them for Zhao Yong to use, and now he is just taking Qigou Pass to test the knife. This shot was not accurate, and hit the weak point of the upper part of the city wall, opening a gap in the wall. After the adjustment, the two cannons took turns to shoot at the bottom of the city wall, but the wall made of rammed earth first peeled off layer by layer under the impact of the cannonballs, and then slipped off in pieces, and finally collapsed under the salvo of the two cannons, not waiting for the smoke and dust to disperse, Yue Fei took the lead and led the troops to the gap, he wanted to be ashamed...
