When the east gate of Lüneburg was pushed open, not to mention that Prince Otto looked confused, even Marin was a little stunned - isn't there still a blasting link? Skipped?

But Schwartz was the first to react:

"Warriors, rush!"

But Marin immediately stopped him:

"Wait! Send someone to sprinkle lime powder first! ”

Marin had studied chemistry and knew how powerful aqua regia was. If it accidentally gets on your skin, it's going to be a big deal. After all, Shui Wang is the legendary corpse water in later generations, and it is too powerful to be good.

Moreover, when the iron gate was corroded before, a lot of royal water was poured on the door, but most of it actually flowed to the ground. Now, the ground in front of the east gate of Lüneburg was watery—all royal water......

If the charge were launched at this time, and the soldiers' running footsteps would splash on the royal water, the consequences would be very serious. Even the soldiers responsible for corrupting the city gates with aqua regia wore several layers of leather-soled boots. Otherwise, the foot will be badly happier. After all, when Aqua regia was first tested, there was a soldier whose feet were corroded by Aqua regia.

For this purpose, Marin specially prepared several soldiers. They carried quicklime powder in leather bags, quicklime is a strong alkali, and sprinkled on the ground just to neutralize the strong acid aqua regia. After sprinkling lime powder, the acid and alkali are neutralized, and there is no fear of aqua regia on the ground corroding the soldiers.

Following Marin's order, several soldiers wearing gas masks, each carrying a leather bag filled with lime powder, holding the removed door panel in their hands, cautiously rushed up to the big iron gate.

Then they began to sprinkle lime powder violently, and the hole in the city gate was full of smoke.

Fortunately, both they and the soldiers sent to corrupt the iron gate with aqua regia before were all wearing gas masks and were completely unaffected by lime powder.

However, the soldiers sent by the Duchy of Braunschweig-Lüneburg to seize the gates of the city have suffered......

When Prince Otto saw that the east gate was forced, he was first confused, and then in horror ordered troops to be sent to retake the east gate. For this reason, the 1,000 veterans who were originally standing on the east city wall and posed in a stubborn posture divided 300 people, hurriedly descended the city wall, and went straight to the city gate hole of the east city gate.

Unexpectedly, as soon as they rushed down the city wall into the city gate hole, they encountered a few "biochemical soldiers" who sprinkled quicklime powder violently. The unsuspecting 300 veterans of the Duchy of Brunswick-Lüneburg were directly recruited......

"Ah, my eyes!" A group of veterans of the Duchy of Braunschweig-Lüneburg, who rushed to the front, were directly covered with the terrible quicklime powder......

Quicklime is a strong alkali, and it reacts violently when it encounters moisture. A group of veterans of the Duchy of Braunschweig-Lüneburg rushed to the front, and their retinas were directly burned by lime powder......

And the veterans of the Duchy of Brunswick-Lüneburg who followed behind also had many recruits. If you react in time and don't get hit, you don't dare to open your eyes at this time, so you can only close your eyes tightly so as not to be hit......

In the distance, Marin saw this scene with a telescope and immediately lit up - a good "biochemical tactic". Let the "biochemical soldiers" in gas masks sprinkle quicklime powder violently, and see who dares to open their eyes?

But it didn't take long for Marin to realize the mistake of this idea - because the Beihai Kingdom's own soldiers were recruited......

The first few Cossack cavalry rushed into the city gate, and when they rushed into the city gate, the quicklime powder inside had not yet dissipated. Then, the horses of these Cossack cavalry were the first to hit......

The horse's eyes were powdered with lime, causing a reaction that burned the cornea. Then, surprised......

In this way, the horses of several Cossack cavalrymen, who were the first to rush into the city gate, began to go crazy.

Because of the damage to his eyes, the already timid war horse was a little exhausted, and he rushed around in fear. After a horse was caught in the quicklime powder, it directly closed its eyes and crashed into the wall in the city gate, the horse died on the spot, and the Cossack cavalry on horseback also fell and was injured......

There was even a horse that turned around and ran back - its eyes were closed. Seeing that the horse was about to storm Marin's position, his men had no choice but to shoot the horse to death......

"This ......" Marin suddenly learned a lesson - it seems that sprinkling quicklime not only harms others, but also harms himself. Unless, everyone wears a gas mask.

However, people can wear gas masks, horses cannot. Horses are inherently timid, and if you put a mask on it, it will definitely scare the horses......

Therefore, sprinkling lime powder or something, it seems that it is only suitable for small-scale special wars, not for large battlefields. At the very least, not suitable for the presence of cavalry.

Fortunately, their own army did not rush into the city, and the opposing soldiers failed to storm the city gate. After all, the most serious sprinkling of lime powder is on the inside of the city gate hole.

Later, a group of sword and shield soldiers stormed the city gates. They don't have gas masks, but they can squint and try to keep lime powder out of their eyes......

After the lime powder was completely dispersed, Marin's soldiers completely controlled the eastern gate of Lüneburg and defeated the defenders.

After all, the absolute superiority in numbers is there. Moreover, Karn put on his full plate armor again and led the charge......

Prince Otto didn't react, and he was captured with his mother by the swarming soldiers of the North Sea Kingdom. Captured with them were Prince Otto's sister Elizabeth and younger brother Ernst.

It should be pointed out that his sister Elizabeth would have historically married Charles II, Duke of Geddes, in 1518, who is now Charles, Earl of Geldon. However, she was captured by Marin's army before she could get married......

After arresting the family of Henry, Duke of Braunschweig-Lüneburg, Marin asked Prince Otto to order the unconditional surrender of the entire Duchy of Lüneburg. The family was then sent to the city of Oldenburg to be reunited with Henry, Duke of Braunschweig-Lüneburg, who was imprisoned there.

……

Next, of course, it was time to loot the land......

The Duchy of Brunswick-Lüneburg was not a poor country like the Duchy of Saxony-Lauenburg. The finances of the Duchy of Saxony-Raunburg depended purely on the "tolls" paid by the merchant ships of Hamburg and Lübeck and the salt ships of Lüneburg when they passed through the Stocknitz Canal. The Duchy of Ruunschweig, but the annual output of the salt mines in the city of Lüneburg is a large amount.

For a long time, most of the salt in the Baltic region was supplied by the Lüneburg salt mines.

Originally, Lüneburg's annual salt output value exceeded one million gold coins. Although many of them were monopolized by the Hanseatic merchants, the Welf family could still make hundreds of thousands of gold coins a year from salt mining, and they were well-known local tyrants and aristocrats in Germany. And the Duchy of Lüneburg is also one of the few vassal states in this era that does not run a deficit in finance.

It's just that later, after the rise of Marin, he started the business of boiling salt with briquettes. Moreover, the quality of washed sea salt is higher than that of most of the salt in Lüneburg, and the cost is cheap, which steals a lot of business. Therefore, in recent years, the income of the Duchy of Braunschweig-Lüneburg has declined, and the Duke of Henry has begun to covet the secret of the high grain yield of the North Sea Kingdom. In the past, when Marin did not intervene in the salt trade in the Baltic region, Duke Henry had a lot of money in his hands, and he might not covet the agricultural secrets of the North Sea Kingdom......

To what extent did the former Duchy of Lüneburg go? Because of the salt mines in the territory, the people of Lüneburg did not bother to engage in agriculture. The huge Duchy of Lüneburg is 10,000 square kilometers in size. However, because the residents are focused on salt mining, they have little intention of developing the land in the country. As a result, in the territory of the Duchy of Lüneburg, there is the largest steppe in Germany - the Lüneburg Wasteland.

The Lüneburg Wasteland was a famous scenic spot in Germany in later generations, and this grassland covers an area of 7,200 square kilometers. In later generations, it was the grassland where the famous heather bloomed, which was extremely beautiful.

What is the concept of 7,200 square kilometers? Two East Friesland provinces are big!

The reason why Marin wants to annex the Duchy of Brunswick-Lüneburg is not only to covet the salt mines here, but also to covet this steppe......

Why? Because this steppe can raise horses and train cavalry......

After all, Germany is an agricultural country with relatively little grassland. Marin is looking for large areas of grassland, but it is difficult to find them. It just so happened that Lüneburg had such a large grassland, which was very suitable for raising horses and training cavalry, but it could not be wasted......

As for agriculture, Marin does not lack this amount of arable land in the Lüneburg region......
