Chapter 1884： Dover Ship

"Captain Jack" 's classic shape, and very funny lines, left a deep impression on the Portuguese sailors. These legends later spread in Portugal and became legends. However, the Portuguese sailors are still in shock, they have to return to the Portuguese mainland first.

At the same time, the Beihai Kingdom also began a tense preparation. This time Captain Jack was sent out, although it was to make up for his own losses. But, God knows how the Portuguese who are overconfident will mess up. Perennial glory on the sea has made Portugal forget that they are just a small country, and they have inflated their confidence.

Therefore, Marin once again began to propagate the two powerful fortresses at the mouth of the Ames and promote their "invincibility." At the same time, 20 500-ton warships of the North Sea State made their first public appearance at the mouth of the Ames River, which caused a huge sensation.

"My God, I always thought that there are only 10 ships like this in the Beihai Kingdom. Unexpectedly, there were 20!" Emden port, some foreign businessmen who came to Beihai to do business marveled. Of course, many of them are spies.

However, in this era, there was no professional spy in other countries. The spies in these businessmen are actually part-time and unprofessional. They are usually businessmen, and then secretly hired by the country where they are located, responsible for investigating the intelligence of the target country. Therefore, they are not professional spies, but just businessmen who spy on news.

This level of spy, in front of the full-time spy in Beihai, is naturally not good enough. Therefore, what they can find is generally what Marin wants them to know. Or, there is no way to hide the news.

However, in this era, we can't ask for more. After all, people can think of using businessmen who do business abroad as spies, which is already very good. The truly professional spies are generally subordinate to the army in this era. In other words, it was a military agent, not a full-time spy. The secret agents of the military rarely ran abroad to pretend to be civilians and search for news. Unless, war is about to break out in that area.

In addition to the Beihai Kingdom, I am probably the only Ming Dynasty in this era, with a professional spy, Jin Yiwei. However, because of his privileges, Jin Yiwei acted a bit high-profile and overbearing, but lost the forbearance of the spy.

Moreover, Jin Yiwei also belongs to the military establishment. Most of the members are illiterate big-head soldiers. Their commonly used means of investigating intelligence is to directly solicit help and get information from the "bag to inquire" in the market, rather than go out like 007 Get information.

Therefore, although Jin Yiwei is more advanced than the intelligence organizations of other countries in the same period, he still cannot escape the shackles of the age. Because there are not many educated members, the level of business is actually the same. Of course, Jin Yiwei is also a master of espionage, which is very clever, but rarely.

But the spies in Beihai State are different from the spies of this era. The spies in Beihai State are all cultivated by the school and are all cultural spies. Moreover, he has received very professional reconnaissance and anti-reconnaissance, as well as modern spying methods such as torture, shorthand, camouflage and makeup. Even being able to master multiple foreign languages ​​belongs to the top talent. If intelligence work is not very important, these spies are more than enough to be local officials.

In addition to the 20 main battleships, Marin also let 20 250-class armed merchant ships follow the main battleships to demonstrate the huge fleet of 40 warships as a deterrent.

In order to demonstrate the force, Marin let the huge fleet sway a few times at the mouth of the Ames River. Then, he left the Ames estuary and went to Antwerp, the Netherlands, for a "friendly visit."

Why is the fleet going to Antwerp? Because Antwerp is the main distribution center for Portuguese people selling Indian spices in Northwest Europe, there are many local Portuguese merchants. Similarly, there are also many Portuguese businessmen who work part-time as spies.

Marin asked the fleet to go to Antwerp, which was clearly intended to be seen by Portuguese businessmen who were part-time spies, so that they could pass the news back to Portugal.

At the same time, Marin also asked the fleet to buy private saltpetre in Antwerp, making a ready attitude. In short, all this preparation is to tell the Portuguese-I am ready to fight!

……

At the same time, 20 lizard cannons purchased from Venice have arrived. After arrival, Emden Shipyard of the North Sea State modified 20 250-class armed merchant ships, and mounted a 7,000-pound lizard gun on the bow as the main gun. At the same time, various enhancements were made to the hull, and oars were added to the side to convert the boat into a sail paddle boat. Among them, a row of single-cylinder diesel engines were also installed on the five converted 250-class armed merchant ships, so that they have the ability to move without fans.

In fact, Marin originally wanted to add a single-cylinder diesel engine to all 20 ships. It is a pity that the manufacturing level of Beihai's single-cylinder diesel engine is too ugly. In addition to the original 10 12-horsepower single-cylinder diesel engines, in a few months, only 30 qualified and durable 12-horsepower single-cylinder diesel engines were manufactured.

No way, limited by the level of science and technology, the single-cylinder diesel engine of Beihai is completely hand-made, which takes time and effort, and the defective rate is very high. As a result, more than 160 new single-cylinder diesel engines were manufactured, and only 30 were relatively durable and could be used for a long time. Others are not qualified at the beginning, or after a period of operation, they always break down and cannot be used for a long time.

But these are not problems, at least, Marin saw progress. In the beginning, the craftsmen of Beihai made more than 100 units, and only 10 units were qualified. Today, more than 160 units have 30 qualified, which is a great improvement. It is foreseeable that in a few years, the craftsmen in Beihai will be more and more advanced, and then the yield of single-cylinder diesel engines will be further improved. After the emergence of several "level 8 mechanics", the output and quality of diesel engines will be guaranteed in the future.

Subsequently, five "Dover ships" with diesel power were tested at sea. The test results show that placing the artillery at the bow of the ship and shooting it from the front has an advantage over the side gun. Among them, the biggest advantage is that if the bow of the bow is bombarded frontally, the left and right swing of the ship will have less effect on its shooting.

When the side gun is rocking from side to side, the accurate head is very poor. Because a little change in the shooting angle will cause a big change in shooting accuracy.

But if the bow gun is arranged on the central axis and flat shot, it will be less affected by the ship's left and right swing.

However, the lizard cannon in Venice is not a flat-fire cannon, but a mortar with a short barrel and a curved barrel. Although the angle has been adjusted as low as possible, the firing angle of the mortar is still more than 10 degrees ~ www.novelhall.com ~ So, the hull's shaking still affects its shooting a bit. It's just that it has a much smaller impact than the side guns.

Moreover, the gunners of Beihai are not vegetarian, they will choose to fire at the moment when the hull is most correct, and try to minimize the impact of the sea state.

The test effect of these 5 "Dover ships" was very good. In order to observe the actual combat effect, Malinte bought two Caravel sailboats with expiring life as target ships, and let 5 Dover ships bombard. Then, because the shells were so powerful, and the sides of the warships of this era had not been strengthened, the two Caravel ships were quickly sunk ...

Seeing such a good effect, Marin also increased his confidence, and ordered the full production of single-cylinder diesel engines, so that the diesel-powered Dover ship would be larger and more lethal.

However, the row of diesel engines behind the "Dover Boat" was too windy and inevitably coveted. Moreover, if the single-cylinder diesel engine algae is unfortunately hit by enemy shells, it is also easy to break.

Therefore, Marin thought of a way to make people repair a large canopy with iron plates at the stern and wrap all 8 single-cylinder diesel engines at the stern. In this way, with the shelter of the iron shed, the eight single-cylinder diesel engines at the stern not only kept the outside secret, but also resisted the threat of enemy shells. In an age when the artillery caliber of other countries is not large, the iron shed is enough to resist the shells of other countries ...
