As the saying goes, 'blue is better than blue'. Pen? Interesting? Pavilion wWw. ｂiquge。 info Zhao Hao's defensive tactics were born out of Septimus? Severius, but combined with the work of other military strategists, to create a system that suited itself. After all, today's scientific and technological achievements are not the same as inheriting and integrating the experience of predecessors, innovating and developing.

As sharp weapons to defeat the enemy, ballistas and rockets are naturally essential items in the army. These are still easy to say for the navy, its carrying tools are relatively fixed, and the size and load capacity of the ship can not be considered for the size of the ballista. However, the infantry army is different, the ballista can basically only rely on people to carry horses, and the size and weight are too large, which will increase the burden when marching and transferring, and it is difficult to move with the army in complex terrain.

Therefore, as soon as he settled down, Zhao Yu considered making the ballista as small as possible without reducing its power, reducing its weight and increasing its portability, so as to ensure that it could move with the army and be suitable for use on most occasions. After the research of him and the craftsmen, the weight of the small ballista was successfully reduced to 200 catties by replacing materials, removing unnecessary parts, reducing the size, and optimizing the structure, and after disassembly, it could be carried by four soldiers on the march.

Even more ingenious, the basic components of the medium and large ballistas could be carried on a single horse, allowing them to move quickly across mountains and rivers, while the bulky wooden pieces could be improvised by cutting down tree trunks at the battle site. Of course, this may delay the use of weapons in the field, but they can be quickly put into operation if needed. In this way, all units of the Qiongzhou infantry army were also equipped with ballistas, each battalion had five small ballistas, and each army had a ballista battalion, equipped with twenty heavy ballistae and five large ballistas.

These weapons are mainly used in siege operations and the defense of field fortifications, and sometimes they are also used in specific field operations, such as covering troops crossing rivers. In addition, in order to cooperate with defensive operations, each army also has a baggage engineering team, which can skillfully carry out bridge erection and the installation and use of special weapons for siege operations. Although they relied mainly on the scene of the battle in search of timber and miscellaneous materials, the engineering detachment had a special baggage detachment carrying the necessary tools and equipment for construction.

In addition, Zhao Yu also formulated a set of regulations for the infantry army to carry out defensive operations through the experience accumulated in the whole training and what he knew in his previous life:

First of all, when the army enters the combat area, it must first set up a fortified camp and use it as a combat and support base. Commanders and staff members should carry out a comprehensive reconnaissance of the enemy's posture and surrounding areas, and in addition to the enemy's deployment, they should also find out the situation of local timber, stone, livestock, food, fodder, and other resources, so as to serve as the basis for a comprehensive assessment of the situation.

Immediately after accepting the task, block the front line, and begin to collect materials for the construction of fortifications and siege machinery, build fortifications, build defensive measures, arrange combat equipment, set up obstacles, and establish a linear defensive area in the position, so as to maximize the range of fire of the combat machinery. If you are fighting independently, you will also need to build defensive lines on the flanks and in the rear to deal with enemy detours and attacks from the flanks and rear.

Eventually, a complete set of covered field fortifications consisting of mobile protective plates, mobile corridors and fortresses was formed, and light and heavy weapons, ballistas, rockets and other similar weapons were continuously used to harass the enemy and disrupt the enemy's deployment. Once the enemy attacked, each unit could rely on simple fortifications to fight the enemy, and could seize the opportunity to counterattack the enemy, and even encircle and annihilate the enemy when he was defeated and retreated.

Of course, this is only a basic principle, and it is not immutable, and the commanders of each department can adjust and add or subtract the use of ballistas and the specific steps of combat according to the environmental conditions at the time and the enemy's combat operations, so as to maximize the effectiveness of weapons and technology......

The west of Quanzhou and the south of the city face the river back to the sea, in the case of the southeast Yuan naval army being hit repeatedly, these are two natural dangers, and it is almost impossible for them to break through the defense of the Baisha naval army. Therefore, the land routes to the north and east of the city can only be chosen as the passage to break through, and the front and rear armies defending these two directions will be under great pressure. In Zhao Hao's estimation, he will definitely choose to go up the river and choose the ferry again, and then join the reinforcements from the north to come to the north to help.

"Commander Huang, it should be strengthened in these directions, you can set some traps in front of the trench, scatter some horse rejection nails, and bury some bamboo sticks. Look at the open field, which is very suitable for cavalry gathering, and we can still plant some gunpowder in advance to disrupt their offensive steps! "In fact, the defensive situation in the north of the city is not good, not far from the city is a hilly area, forming a high terrain in the north and low in the south, it is always easy to attack from high to low, and it is relatively difficult to defend. Zhao Yu pointed to the weak points in the defense.

"Your Majesty, your subordinates will arrange this!" Huang Xianyao nodded.

"You fought very well in this feint attack on Beicheng, and the losses were not small, but you didn't make it to the city, so you feel uncomfortable!" Zhao Yu twisted his face and said with a smile.

"Your Majesty, your subordinates don't dare!" Huang Xianyao immediately saluted.

"There's nothing to dare, I paid such a big price, killed and injured hundreds of people, but it seems to be fruitless, and I am not happy that this matter will fall on me!" Zhao Yu waved his hand.

"Your Majesty......"

"Don't be like this, I remember all your merits!" Zhao Yu saw that Huang Xianyao was a little excited, smiled and asked, "Have you been into the city, have your family found it?" ”

"The war is urgent, and my subordinates haven't had time to enter the city yet, and the whereabouts of my family members are still unknown!" Huang Xianyao hurriedly replied.

"I don't want you to learn from Dayu three times and not enter the house, the war is not urgent in the past two days, hurry up and enter the city to see if you can find your family!" Zhao Yu said with a light sigh.

"Yes, Your Majesty Xie cares!" Huang Xianyao saluted again, "Your Majesty, there are many villagers who have come to the camp to inquire about their relatives in recent days, and in order to prevent leakage, their subordinates have not let them enter the camp, and please ask Your Majesty to show you how to deal with it!" ”

"Well, you're doing the right thing. But the way is not proper, there are a lot of Quanzhou people in our army, so it will make everyone sad. You can set aside a special area in the camp to send someone to receive you, record the situation to help you find it, arrange a visit if you are in Joan or in the army, and give you a compensatory if you have been killed! Zhao Yu thought for a while and said, "As for the officers and soldiers in the army, they should also be properly appeased, and they can help them contact their relatives to settle in the city and go to meet in batches!" ”…… (To be continued.) )
