Marin's siege along the way was as simple as drinking water, which terrified the Danes. www.biquge.info Of course, his "three-plate axe" was also figured out by the Danes by coincidence. No, the Danish royal palace once again convened a royal council because of Marin's siege tactics to discuss countermeasures.

"Knight Haisen, you mean that Marin's bastard relied on artillery to attack the city, and did not send people to climb the city walls?" King Hans was surprised when he heard the report of the spy Heisen. Because, this is not in line with convention. Moreover, Marin broke the city too quickly, and it was as easy as eating and drinking water to capture a city in three or two days, which was really terrifying.

"Yes, the retainer escaped from Flensburg in the Duchy of Schleswig. Before, the minister had never figured it out, but in Flensburg, the minister saw with his own eyes the methods of Marin's demons, and it was really different......"

"They first bombarded the city gate with dozens of heavy artillery. When the oak gate was blasted into a large hole, they shoved gunpowder into the hole and blew the gate open...... Then, the army of the other party poured into the city like a tide...... "Recalling that scene, Knight Hazen is still terrified. If it weren't for the fact that after the city was broken, Knight Haesen took off his armor in time and hid in the toilet of a house, he would definitely have been captured as a prisoner.

Later, as Marin's army continued northward and the city's defenses were relaxed, the Knight Haussen disguised himself as a beggar and escaped from Flensburg, found a fishing boat, and returned to his hometown of Zealand.

Knight Haisen was a native of Zealand and was sent to garrison Flensburg as one of the lieutenants of the local garrison generals. After escaping, Haisen understood that if he could not make meritorious atonements, his knighthood and fiefdom manor were in danger of being taken back by the imperial court. So, he ran to Copenhagen and, in the name of a survivor, in front of his ministers, reported to the Danish king Hans what he had seen with his own eyes on Marin's siege tactics.

"What a tactic! The method of burying gunpowder could not shake the walls, but it was fine with blowing open the oak doors and the bricks and timbers that had piled up behind the oak doors...... "Secretary of War Simonson commented.

Of course, that's Simonson's lack of knowledge. Even a well-built wall can be blown down if enough gunpowder is buried under the wall. A barrel of gunpowder can't blow up a solid city wall, so it's dozens of barrels......

"Knight Hazen, do you mean that the other party must blast a hole in the city gate before burying the powder keg?" Admiral Thomas frowned and asked.

"Yes, that's it, I heard from the soldiers who fled back from the city of Schleswig, and every time the other side blasted a hole in the city gate before stuffing the powder keg into it. If you don't open the hole, you don't seem to use a powder keg. ”

"So, that is, the powder keg must be placed in the hole to explode?" Thomas asked.

"I don't know ...... lowly position" Hayson had only seen this meeting, but he didn't understand the reason.

"That's it, let's find a door and try it......" suggested Erikson, the foreign secretary on the side.

This time, Erickson brought back 200,000 gold coins, 50 bronze cannons, and a lot of gunpowder and shells from France, and took out a few barrels of gunpowder to try, but it was nothing.

So the Danish king Hans, with his courtiers, went outside the city, asked an earl to borrow two doors from one of his castles on the outskirts of Copenhagen, and began an experiment......

Behind the two gates, like a siege scene, the back was full of things, and they were behind the door. However, one gate was intact, and the other gate was left with a carpenter to drill a large hole in the middle of the door with a tool, so that the powder keg could be put in.

It took half a day and dozens of carpenters to drill a large hole in the middle of the thick castle gate to hold a powder keg inside.

Then, two doors were subjected to powder keg blasting tests......

With two loud bangs, the Danish courtiers saw a different scene......

There was no hole to dig and only the powder keg was placed outside the gate for the explosion test, and although the gate was damaged, there was still nothing wrong with the city gate. After all, the harder you hold the bomb, the more intense it will explode. Gunpowder can be used as a bomb in a tin can, but it can only be used as a firecracker in a paper bag......

And the gate of the castle where the hole was dug was thrown and the powder keg was thrown inside and exploded. The tremendous impact smashed the heavy castle door from the inside. Of course, the masonry piled up behind it also suffered a huge impact, but it did not collapse.

This is because the Danes used powdered gunpowder. And in the Marlin army, especially the artillery, the use of granular gunpowder was promoted. Only the musketeers, because of the problem of the production of granulated gunpowder, for the time being, still used powder. The powder kegs used to blow up the city gates, naturally, were taken from artillerymen, and they were naturally granulated gunpowder, and the explosive power was two or three times stronger than that of powdered black powder. So, naturally, the effect is better.

Despite the use of powdered gunpowder and the poor degree of burial, the Danish courtiers were able to see that the powder kegs stuffed into the hole in the gate still overturned the heavy oak gate.

Therefore, the Danish monarchs present all came to the conclusion that the oak gates, which were basically inexplicable to the rogue siege tactics of Marin, would definitely be broken......

Once the city gate is breached, unless the defenders of the city are no less than the attacker, and no worse than the attacker's combat effectiveness, the fall of the city is almost inevitable.

"How's that good? How can this be a good ......," the Danish king Hans nervous. If this method of siege is not solved, then the fall of the cities on Jutland is only a matter of time. Moreover, the time will be short.

Even, if the coalition forces attack Zealand and besiege Copenhagen, they can successfully blow up the gates of Copenhagen by using this method. Then, Hans might become a prisoner...... Thinking of this, King Hans trembled with fear, afraid that day would come......

Back at the palace, the ministers were pondering what to do. In the face of such a complicated situation, everyone was a little sad......

Chancellor of the Exchequer Dawerson began to wander his gaze, he did not understand the military and was only responsible for appropriations. Every time the army is funded, it is a quarrel. Since he didn't understand, he didn't bother to give his opinion.

However, after seeing the door of the inner sanctuary, which was covered with gold skin for show, Dawson's eyes suddenly lit up:

"Your Majesty, the minister has thought of a way!"

"Aiqing, tell me quickly, how to deal with it?" Hans looked expectantly at Daulson, a layman who didn't understand military affairs.

"Your Majesty, let's replace the city gate with an iron gate!"

"Iron Gate?" King Hans was stunned.

"Yes, listen to the Knight Haessen, the other side will use artillery to bombard the oak city gate, and it will take at least half a day. If the city gate is replaced with an iron gate, will the other party still be able to blast it open? Dawson said excitedly.

"Iron Gate...... Artillery...... Oops, what a great idea! Admiral Thomas thought about it, then patted his thigh and said excitedly.

"That'...... Let's try? Foreign Secretary Eriksen said.

"Okay, just try it! Come on, go and get me all the blacksmiths for the whole journey, and let them build a heavy iron gate together! ”

In this way, the blacksmiths of the whole of Copenhagen were summoned by the royal family to build a strong gate out of iron and use it for experiments......
