After dealing with the extremely powerful figures of the Archbishopric of Cologne, Marin did not go to Münster City, the capital of the Münster Episcopal State, to continue bribing the Bishop of Münster, but directly led the team back to China. Pen % fun % Pavilion www.biquge.info

Marin felt that at this time, it was better not to let the Bishopric of Münster know the news. If they have bad ideas, getting the news in advance will give them time to prepare.

Anyway, their own army is ready. When the time comes, the Holy See will order that he will directly rush into the Bishopric of Münster with a large army.

Unlike the Archbishop of Cologne and the metropolitans, this decision of the Holy See is tantamount to depriving the Bishop of Münster of secular governance and directly affecting his interests. And the Archbishop of Cologne and the metropolitans had nothing to lose. Therefore, the Archbishop of Cologne and several metropolitan bishops are easily persuaded, and the Bishop of Münster, as a party whose interests are harmed, is not so easy to say.

Even if he can't resist openly, it would have been easy for the Bishop of Münster to have been in charge of the Bishopric of Münster for many years and secretly stumble Marin.

Therefore, Marin intends to take it by surprise. Wait for the order of the Holy See, and directly march to the city of Münster with a large army. Wait for the soldiers to come to the city, and then negotiate. In short, it is not to give the other party time to react.

In addition, because he had not considered the affairs of the Episcopal State of Osnabrück, Marin did not send his men to the Episcopal State of Osnabrück to collect information. At this time, it is time to send someone to the Episcopal State of Osnabrück to collect information, so as not to have problems due to insufficient intelligence when the army passes by.

The Episcopal State of Osnabrück is only a weak episcopal state, which can exist safely mainly thanks to the prestige of the Holy See and the Archbishop of Cologne. The country is small and weak. If it weren't for the strong backer, it would have been destroyed long ago.

So, the Episcopal States of Osnabrück and the Episcopal States of Münster are different. The Bishop of Münster is powerful, after all, in the whole of Germany, there are not many people with a land area of more than 10,000 square kilometers, just a few. Therefore, the Bishopric of Münster is still more difficult.

As for the Episcopal State of Osnabrück, as long as it sent 10,000 troops to besiege the city, and it had already been abandoned by its backers, it was only a matter of time before it surrendered.

What's more, Marin heard that the army of the Episcopal State of Osnabrück was only seven or eight hundred in total, and its combat effectiveness was average. The Bishopric of Münster, on the other hand, has a standing army of 5,000 and is a powerful country.

After all, to feed 5,000 mercenaries, the salary alone costs nearly 90,000 gold coins a year, and not any country has so much money to feed so many mercenaries. It can be seen that the financial situation of the Bishopric of Münster is quite good.

Of course, the strength of the Bishopric of Münster is not yet in Marin's eyes. If it weren't for the fear of the Electors of Saxony and Brandenburg intervening, the 5,000 soldiers of the Bishopric of Münster alone, in Marin's eyes, would be a P. Don't you see, the Duke of Saxony's 20,000 elites have been defeated by Marin? 5,000 centaurs, what is it?

Upon his return to East Friesland, Marin had Schwartz intensify his training of recruits. Because of the urgency of time, this batch of recruits, especially the last 5,000 recruits, may not be able to train for 3 months as originally planned. Probably, after more than a month of training, you will have to set off. So, Schwartz's training task is heavy.

Fortunately, with the assistance of the 200 young officers who came out of the crash course, this group of recruits was able to form a certain combat effectiveness as soon as possible. After all, the power of example is endless. With 200 theoretically experienced officers under the guidance, I don't know how high the combat effectiveness is, but it is certainly much faster to complete the training requirements than without these officers.

In order for the recruits to form combat effectiveness as soon as possible, it is not enough for these 200 officers with solid theoretical skills. To this end, Marin transferred 1,200 veterans from the veterans, and replaced 1,200 recruits from the recruits. The new recruits who were exchanged were carried by the veterans, so they naturally got started quickly. In the recruit army, there is an average of one veteran for every ten people as a squad leader, and under the leadership of these veterans, the recruits can also get familiar with the business faster. At the same time, in the event of a battle, under the leadership of these veteran squad leaders, they are able to quickly adapt. After all, with the words and deeds of veterans, recruits are more likely to adapt faster.

……

Before the expedition, Marin had been thinking about one issue -- that is, the question of domestic security......

After Marin came up with the tactic of artillery bombardment + powder keg blasting, the oak gate became an ornament in the face of artillery. The case of George's capture of Leeuwarden tells Marin that his own country's cities can be conquered by the enemy using the same tricks.

Although it is said that the city of Aurich has been replaced with four large iron gates, and there is no longer any fear of being damaged by enemy shelling. However, in other cities, there are not. In particular, the Duchy of Schleswig, which may face reprisals from Denmark at any time, is the most dangerous.

You know, the Danes suffered Marin's loss, but apparently also learned Marin's tricks. If the gates of the Duchy of Schleswig were still oak, they could easily be breached by the Danes with the same tricks.

Originally, Marin planned to wait for the zinc from the Tara lead-zinc mine to be in place, smelt the zinc, make thick white iron sheets, and cover the city gates, so that there would be no need to worry about the enemy's shelling. After all, the shells of this era are all iron balls, and the power of the stimulant is not very large, as long as the city gate is covered with iron sheets, it will be difficult for the enemy to break through.

Just like Oriental China, the city gate is covered with copper skin and painted with red paint, so it is not afraid of the bombardment of ancient smoothbore cannons. However, in Europe, it is very unrealistic to cover the city gates with copper skin. Because, the price is too high.

Europe is not the Ming Dynasty, the Ming Dynasty, the exchange ratio of silver and copper, as high as 1 to 130, the price of copper is very cheap, naturally there are conditions to use copper skin and copper nails to cover the city gate. But what about this era in Europe? The exchange ratio of silver and copper is 1 to 15, and using copper to cover such a large city gate is definitely something that a local tyrant can do......

However, it is useless to cover it with an ordinary iron sheet, and after a few rains, it will immediately rust. The rusty iron sheet, the shell broke as soon as it was smashed, and it was not used at all.

However, the Tara lead-zinc mine, which has just been acquired, has not even been explored, and it is too late to make white iron sheets to the gates of the East Friesland, Oldenburg and Schleswig regions.

And the city gates in these three areas are replaced with large iron gates, which is too expensive, even if Marin can't afford it.

An iron city gate weighs at least seven or eight tons, and a city needs several. and how many cities are there in a kingdom...... In short, the consumption of iron is too amazing......

At present, in Europe, blast furnace ironmaking is not popular, and ironmaking is simply replaced by ordinary charcoal furnaces, with low output and poor quality, but the price is very high.

Therefore, it is very unreliable to popularize iron gates in the cities of all three countries......

After thinking about it, Marin suddenly remembered the tinplate commonly used in tin cans in later generations. It is to soak the iron sheet in the tin liquid and hot-plate, and it is very simple to obtain anti-rust tinplate.

The anti-rust ability of tinplate is very good, and the only drawback is that the tin layer on the iron sheet cannot be destroyed. Otherwise, the point of the destroyed tinning will become the diffusion point of the rust of the iron sheet.

The galvanized white iron sheet perfectly avoids this shortcoming. Because, the galvanized layer, even if it is destroyed a little, as long as the range is not large, it is not a big deal, but can continue to be used. That's why Marlin thought of using zinc. Moreover, the Tara lead-zinc mine in Ireland has a large zinc reserve, and it stands at 10% of the ore content, the reserve is very large, and the cost will be very low if it is refined. At least, much lower than tin.

But now, Marin doesn't have time to wait for the Tara lead-zinc mine to produce zinc. Because, war can break out at any time. So, after much thought, Marin decided to use all the 15 tons of tin in reserve, which was intended to be used to make counterfeit money, to make tinplate.

Before the zinc is produced from the Tara lead-zinc mine, the city gate is covered with tinplate and held up for a while. Wait until the zinc is produced, and then replace it with a white iron sheet.

As for the situation that the tinplate tin plating layer is easy to cause problems once it is broken, Marin also quickly thought of a solution......

Nail tinplate to the city gate, nothing more than the destruction of the tin plating layer on the nail hole. Therefore, Marlin decided to nail out the nail holes with iron nails before tinning. Then, it is put into the tin liquid for hot plating. In this way, when nailing tinplate to the city gate, as long as the nail is driven into the nail hole, try to be careful, and the tin plating will not be damaged.

As long as the tin plating is not destroyed, tinplate can be used for a long time. Even if the enemy army comes to attack with artillery, the city gate covered by tinplate can withstand it for a long time.

In fact, Marin urgently made tinplate sheets this time and divided them into cities in the control area, that is, to withstand this wave. Once Marin succeeded in taking control of the Bishopric of Münster and the Bishopric of Osnabrück, and the army of 20,000 was free, it didn't matter whether the gates were covered with tinplate or not. Whoever dares to invade their own territory can just go back......

However, while Marin was preoccupied with conquering and controlling the Bishoprics of Münster and Osnabrück, Marin was not free to control anything else. Therefore, it is still necessary to issue some tinplate sheets and nail them to the gates of cities in the country, so that they can withstand the enemy's attack for a while......
