August 29, the seventh year of Hongwu.

The sea breeze passed by the city of Jiahe Fort coldly. There were no traces of soldiers or soldiers on the low city, and there was no trace of defense. There was only a red scarf of the Song army's sun and moon flag and a flower-shaped flag dancing.

Based on the cognition of this era, this Jiahe Castle is a vulnerable castle.

First of all, the city wall is too short, only more than one meter high, which is about four meters in the later generations. It is not perpendicular to the ground, but has an oblique angle of about 60 degrees. The surface is not smooth, but is built with sandbags. The gap between the sandbags and sandbags is extremely large, and you can climb up with bare hands.

Secondly, this fortress has no "defense" and is a "naked city" according to the standards of the Song Dynasty. The city defense of the Song Dynasty was different from the city defense of the Ming Dynasty, which later relied on firearms. There were many "fragments" inside and outside the city walls. There were walls outside the city, ditches outside the walls, pits outside the ditch... There were holes under the city walls, door guard walls, and tiger falls. There were female head walls, forks, magpies, stylus, crossbow machines, as well as various sheds, wooden boards, and of course, there were rolling wood, stones, stoves and iron pots for boiling "gold juice". Inside the city walls were inner trenches, inner walls, and the inner walls were also filled with "fragments".

Moreover, these "fragments" are basically consumable and easily damaged objects, so a large number of spare parts must be prepared and ready to replenish the losses at any time.

Most of these "fragments" are not easy to preserve, such as cannons, crossbows, etc. If you do not maintain them carefully and store them carefully, you will be eaten by insects or moldy in a few years. Therefore, you cannot prepare them in large quantities in daily life, and they are usually built only in the war.

In addition, it is very inconvenient to transport these things. They are all shoddy handmade products, and they may be broken if they are disassembled and assembled.

Therefore, in an era where cold weapons are the main reason, the cost of comprehensive defense of a castle was extremely high... The cost of the project was far higher than the pre-installed artillery era.

Even according to the high standards given by Zhao Kai, a prism with six sides and twelve corners requires the deployment of 72 types of artillery, which costs only tens of thousands of jin. Moreover, bronze cannons are durable products and are convenient for transportation. They can completely move east cannons and replenish western cannons, and use good cannons in key places.

For example, now, Zhao Kai brought more than 300 cannons to the Pingzhou front, and the number of "supervised cannons" was included (casting cannons is not difficult for the current Northern Song Dynasty, but the artillery group and the ammunition truck are not enough to pull the horse). But he still collected 72 cannons, accompanied by artillery groups, plus three battalions of infantry, and handed them over to Meng Lin, the general general of the Ninth Army and artillery. He asked him to bring the cannons and infantry to enter the Yanghe Jiahe Fort, the first battalion in human history, Yanghe Jiahe Fort. He was looking forward to becoming the person who created history...

However, Meng Lin was far less confident than Zhao Kai at this time... Although he had heard Zhao Kai explain in the artillery school that shot shot sideways to form cross fire, which could greatly improve the efficiency of killing.

But now there are tens of thousands of Jin soldiers surrounding Jiahebao!

How can 5-pound cannons and 10-pound cannons be so efficient? Can more than 40 cannons kill tens of thousands of people? Are you kidding?

Meng Lin was now huddling behind the mercedes made of sandbags, using a telescope to observe the huge lineup of golden thieves that had already spread around Jiahebao, and felt so cold!

So many... If you come up one by one, the cannons in Jiahe Fort might have time to kill them. If you rush forward and concentrate your forces to attack several Sanling Forts, how can you kill them with the crossfire formed by four or eight long cannons alone?

In addition, the Golden Thieves also have cannons, and there are quite a few!

Meng Lin had already seen dozens of carriages with sandbags and hundreds of civilians. Under the escort of dozens of scattered Jin soldiers, he drove out of the Jin soldiers' formation and approached three or four hundred steps east of Jiahebao East Fort. Then the carriage stopped, and the civilians began to carry sandbags down from the carriage, and under the command of the Jin soldiers riding horses, they piled up the sandbags to form crescent artillery bunkers.

Meng Lin counted and found that there were thirty-two gun positions in front of Jiahebao East Fort!

If a cannon is placed at one cannon, then there will be thirty-two cannons on the thirty-two cannons!

If the Golden Thiefs besieged Jiahebao West Fort also had so many cannons, the Golden Thiefs would use 64 cannons to bombard Jiahebao!

Although the Song army in Jiahebao had 72 cannons, and the number seemed to be relatively large, twenty-four of these 72 cannons were not very useful. The ones that could really be used in the battle of defending the city were forty-eight long cannons... The number was actually quite large, but these forty-eight cannons were scattered in various cannon positions and could not be concentrated and used.

It is already very crowded to place four cannons on a Triangle Fort, and no matter how many, it will be impossible to open it. The walls of the core fort are blocked by the Sanling Fort, so they can only place some hot pot cannons with a curved shot.

The thirty-two cannons of the Jin soldiers could even be concentrated to bombard a Sanling Fort - in fact, Wanyan Xiebao was planning to do this!

He is now standing on a high platform on the east bank of Yanghe River, piled up with straw bags filled with grain. The platform is located a thousand steps away from Jiahe Fort, and it is difficult for the cannons on Jiahe Fort to hit this platform.

"King, the Hedong Tube Team has just reported that all thirty-two gates and ten kilograms are in place. The gunpowder team is preparing gunpowder!"

The person who reported to Wanyan Xibao was his deputy Wanyan Huo Nu. Because his father Lou Shi died of the Song army's artillery, Wanyan Huo Nu determined to "learn the pot" and became the founder of the Dajin Guojun. Later, he learned the tube and the cannon, and became a firearm expert who was proficient in pot techniques, tube techniques and cannon techniques.

In addition to the tactics of the sacred sacred that Wanyan Xiebao copied from the Western Tang Dynasty, the tactics and tactics of the Jin army's Guojun and the Twin Clan army were all explored little by little by little by little... Of course, he also learned from some methods of the Song army during this period.

For example, using sandbags to pile up "hot pot bunkers" and "bottle bunkers", "frying gunpowder" in front of the formation, and using silk bags to load medicine, etc., were all copied from the Song army. When Zhao Kai first used hot pot cannons and fried pots to deal with the Western thieves, he did not prepare granular black gunpowder, but "frying medicine" in front of the formation. This method was seen by the Western thieves, and later it was passed to the Jin people.

So the three armies of the Golden Man's "pot, tube, cannon" are now also following the "pharmaceutical smelting team" that looks similar to the Chef's... Now the "pharmaceutical smelting team" has entered the market. Just behind the tube position, the "gunpowder pick" is arranged, and the brass "small pot" is set up, and then the small smelting, toner, and sulfur powder are poured into the "small pot" with a small wooden shovel, and then the heat, toner, and sulfur powder in the small pot are turned on until they are completely mixed.

Although the "fried medicine soldiers" of the Jinzhezi don't know how to make the pelleted gunpowder, they have roughly found a relatively easy-to-use gunpowder formula, so the power of gunpowder is still acceptable.

After the gunpowder is mixed, the "frying medicine soldier" will pack the gunpowder in the pot into a silk pocket and hand it over to the deputy next to him, and let the deputy send it to the "tube soldier" in front of him...

When the gunpowder bag and stone balls (the large tubes of the Jin soldiers do not use iron and lead bullets, but prefer to use stone bullets that are easy to polish) are stuffed into the tube mouth and pressed with a pole rod. The "tube head" of the Jin soldiers (cannon leader) will aim at them personally, and then raise a small red flag.

When all the thirty-two small flags are raised, it means that the thirty-two large tubes can be volleyed - volleys, but they will not concentrate on sighting.

Because the casting of "bottles" is relatively careless and has no pursuit of standardization, and they are different in height, fat and thin (laughs later began to pursue standardization), and their caliber and bullet weight are also different (10 kilograms are only about 10 kilograms), so naturally there is no way to look at them uniformly.

However, Wanyan Xiebao had already issued an order before that the soldiers on both sides of the Yang River would choose a Sanling Fort as their concentrated bombardment!

"Put the tube!"

Wanyan Xiebao shouted loudly, "First hit him ten cylinders and knock down the triangle platform in the middle of the Lone King!"

"Here!"

The soldiers immediately responded, and then a large red flag was erected!

The red flag rises and the tube is placed!

Balls of fire suddenly appeared at the mouths of the tubes, and then the roar of smoke rising and the earth shaking.

Meng Lin, who was lying behind the wall of Jiahe Castle, watched the battle, and saw a scene, his heart was suffocated, and he even shouted in his heart: Bastion, you must hold on!

Thirty-two "stone balls" have been sprayed out of the mouth of the tube, whistling through the air, and holding the strong wind, they rushed towards the Song army's fortress!

From where Meng Lin was, he saw many black dots flying towards him at a speed visible to the naked eye... The speed was so fast that he didn't even think about hiding.

It was a long time to say that, in the blink of an eye, more than ten black dots had already hit the trunk and made a loud "slap" sound... Then, it seemed that nothing was going on, and the trunk remained unmoved! The stone meatball was either bounced open or simply crawled into the trunk "body" and disappeared.

The target selected by Wanyan Xibao is the No. 2 Triangle Tower Fort in Jiahebao - it is a castle used to cover the No. 2 City Gate. Triangle Tower Fort is its scientific name, because from a geometric perspective, it is a very strong Triangle Tower, with one side facing the city gate and one side facing the city gate.
