Chapter 1740： corrosion

In just one day, the 20,000-strong English army completed the landing with great speed. In fact, some 20,000 people were busy training to land on the beach with rafts. After practicing for so long, in this actual combat, natural practice makes perfect.

After landing, the army quickly surrounded the fortress of Calais and cut off all roads leading to the French interior. Even the British army sent a large number of soldiers, destroyed all bridges leading to the French interior, and dug a lot of roads to hinder the advance of French reinforcements as much as possible.

Subsequently, the army began an offensive against Calais. In order to divert the attention of the French defenders from the sewer in the northwest corner, the British army did not attack the northwest corner of Calais when they launched a feint, but put the direction of the attack on the four city gates to focus the enemy's attention All attracted to the side of the city gate.

Then, the British army was pretending to wait while it rained ...

According to speculation by court astronomers in London, there may be rain near Calais in the next few days. Once it rains, it's time for Li Ying to conquer Calais ...

On the side of Paris, France, Francois I and the ministers calmed down after the initial panic. Because, good news came from Calais-the British army did not immediately capture the Calais fortress!

For the very strong fortress of Calais, the most dangerous time is actually at the beginning. Because if you are not prepared to be attacked, even a strong fortress will easily fall.

In addition, the Parisian princes worried that there was a secret passage left by the British in Calais Fortress, or that there were hidden soldiers in the city who should help open the city gate.

However, two days later, the city of Calais still did not fall. This shows that the British army did not have a start, and the Calais Fortress is still safe.

If there is no secret road or Nei Ying should wait for the backhand, the French government and opposition agreed that within a few months the British could not beat the Calais fortress. So, they started to call the army with confidence ...

The French army is different from other countries. The German army has hired soldiers, and the soldiers are full-time soldiers who are out of production. The French feudal sub-enclosure system is heavily involved. Those 15,000 French knights did not actually serve in Paris. The troops stationed in Paris usually are mercenaries composed of civilians. And those knights with caiyi are actually in their own manor. Only after receiving a call from the royal family would they gather in Paris.

If it is normal, they generally like to stay in a big city like Paris. However, this is the time of spring cultivation. Most of these knights with their own estates help to cultivate or supervise the cultivated land at home, basically not in Paris.

Therefore, it took time for Francois I to call for reinforcements. As for using the Paris garrison to reinforce Calais? Impossible, the king's life is not important? The ten Calais fortresses are not as important as the lives of the kings and ministers in Paris ...

Moreover, Francois I and the ministers generally judged that the fortress of Calais could be kept for at least a few months. Therefore, when calling the knights everywhere, they did not ask those knights to come immediately, but left a two-week assembly period.

In the opinion of the French ministers, the English gang of Jiangyang thieves is by no means an opponent of the mighty French Knights on land. Do n’t look at the fact that the English are besieging Calais, but as long as the French Knights arrive, they will definitely be able to defeat the gang of English gangsters.

This is indeed the case. If the English cannot capture the Calais fortress before the French knights arrive, there is only one way to go. Because the English army is in the wild, it is indeed not an opponent of the French Knights. Longbowmen's advantage is nothing but a few decades ago. Ever since the pig iron ingot technique was used, the French Knight's plated longbow made it difficult to shoot through. After all, the strength of pig iron plate armor is much higher than that of sponge iron plate armor. Moreover, there are dozens of artillery guns in Paris that are not pulled out ...

However, that is the general case. However, the situation is not normal now ...

Three days later, the rainy day predicted by the British court astronomers finally arrived ...

At night, it rained moderately in Calais. Most of the torches in Paris are extinguished. Only in the covered building like the gate tower, the torches were not extinguished by heavy rain.

At this time, near the corner of the northwest city wall, a few figures came ...

They are the spies who are responsible for corroding sewer iron gates with aqua regia. They brought the newly prepared aqua regia and a gas mask to prevent the poisonous gas released during the aqua regia corrosion of the iron gate.

This is the second-generation gas mask. The first-generation gas mask is made of soft elephant skin. Although the effect is good, it is not particularly good. The second-generation gas mask is made of vulcanized natural rubber produced in Cuba, and the effect is better.

In the middle of the night, there were no staff on duty at the wall of the military barracks that was responsible for supervising the sewer gates dozens of yards away. After all, they can't even use torches.

But the French are still vigilant, and about every half an hour, the barracks will send people to the wall in the rain. Although you can't look after it with a torch, you can listen to the movement of the sewer iron gate with your ears. If someone smashes the door lock, there must be a loud noise ...

However, they are miscalculated ...

A total of four spies sent by the Beihai Kingdom this time, two of them were responsible for corroding the iron lock of the iron gate with the royal water in glass bottles. And the other two, one is responsible for holding a large black cloth umbrella to protect the rain from the others, and at the same time, blocking the light ...

After all, the two people who are responsible for corroding the iron lock with royal water cannot smear the corroding iron lock ...

But they did not use torches or candles to light, so it was easy to be found by the French army. They used a very precious lighting appliance-the night pearl ...

Although the night pearl is expensive, Marin specially approved a night pearl for the operation of the spies.

Before departure, the four people illuminate the night pearl in front of the candlelight for an hour ~ www.novelhall.com ~ Then, this night pearl can keep glowing for a few hours.

Although the light is a bit weak and not as bright as candlelight, it is enough to deal with the big iron lock when the black cloth is covered.

Under the black cloth, in front of the sewer gate in the northwest corner of Calais, two North Sea spies sat on a small bench. Under the low light of the night pearl, carefully opened the glass bottle containing the royal water and slowly Pouring the king water on the iron lock ...

It should be pointed out that these four guys, regardless of whether they are pouring aqua regia, holding umbrellas or holding the night pearl, are wearing second-generation rubber gas masks ...

Wang Shui fell on the iron lock and made a "chattered" corroding sound. But the sound is very low, plus it rains at night, even on the top of the city, I can't hear it ...

In the process, a team of French patrols patrolled the city walls under the rain. They were prepared to prevent the English from climbing the wall in the middle of the night, but they did not hear the faint "chirp" sound from the iron gate of the sewer under the city ...

With the faint “chirping” sound as faint as coke bubbling, the large iron lock of the iron gate of the sewer in Calais was corroded a little bit ...
