"Your Highness, are you really sure to break through the Seine defense line from the city?" Falkenhein still seemed a little worried.

"Just try it! In the city, there are the stone shore bases I need on both sides of the Seine River!" Chen Tian smiled cunningly, "The two armies are facing each other, especially when fighting on the French territory. Spy must be everywhere in every corner, so I am not convenient to inform you of the specific strategies now. Please do not inform others of our army. Our army will launch an attack from the city! I also hope that the Chief of Staff can do me a favor, launch a shelling of French positions in different locations every day, and as fiercely as possible!"

"Oh..." Falkenhein nodded, "This is no problem!"

"Okay, I need a week to prepare, and other troops will complete rest and attack preparations during this period. This line of defense seems solid, but as long as a large break appears, the entire line of defense will lose its effect!" Chen Tian looked at the French defense line on the other side with a little regret. The Frenchman's ability to build defense lines seemed to be quite strong. With a Seine River, he blocked millions of elite German troops.

"Then I'm waiting for the good news from Your Highness!"

Judging from Falkenhein's expression, he seemed to be between believing and not believing. Anyway, he would not place all his expectations on Chen Tian and his troops. Chen Tian thought it would be good, at least the French would not notice any strange smell.

After a brief patrol of other parts of the front line, Falkenhein and Chentian returned to the command center with different emotions.

When Chen Tian returned to the station, the soldiers were busy unloading tanks and armored vehicles from trains. Org and Guderian were talking not far away, while François's First Infantry Army and Chen Tian personally commanded the Third Infantry Army will all arrive tomorrow and the next two days.

Chen Tian asked the driver to stop next to them by seeing the car directly.

"General Orger, Colonel Guderian, I happen to have something to discuss with you. Do you have time now?"

"Yes, Your Highness the Prince!" the two of them replied while saluting the army.

"Well, it's great! Come to the Legion Command later!" Chen Tian said that, and rolled up the car window, and the car drove away.

Orger and Guderian looked at each other, gave a few instructions to the school officials next to them, and got into their carriage and rushed to the Legion Command.

Where they left, tanks were moving their bulky bodies, and the roar of the engine and the soldiers' command shouting with confidence.

When Orger and Guderian came to Chentian's office, Chentian and Hoffman were already waiting there.

The room was filled with a strong coffee aroma, while Chen Tian and Hoffman were sitting on the sofa and savoring coffee. There was also an exquisite coffee maker on the coffee table in front of them, and the other two coffee cups with oriental characteristics seemed to be prepared for both of them.

"Please sit!" Chen Tian signaled the two of them to sit on the sofa together, as it seemed that this did not look like a formal meeting.

"Your Highness the Prince comes to us, it's not just for the sake of tasting coffee!" Orger said half-jokingly.

Guderian sat down with some restraint and listened quietly to the other people's words.

"That's right. I just visited the front line with the Chief of Staff and followed the French army's Seine defense line to close the distance." Chen Tian gracefully held the coffee cup and told them what he had seen and heard before.

"This line of defense seems ordinary, but it is actually not simple at all!" Orge said with some regret. "It's a pity that our tanks are landslides. We can't cross the river without the help of a pontoon bridge, unless the river is only half a meter deep."

"Diver tanks are theoretically feasible, but our technical level is far from reaching. Perhaps in 20 years, tanks that are not afraid of water will appear." Chen Tian remembered those wading tanks with long ventilators on their heads. If there is that kind of thing, the Seine River is no different from a small ditch.

Unfortunately, it is the 1910s.

Guderian thought silently alone without saying a word.

"My plan is to find a breakthrough from the French army in the city to the river defense line. After crossing the river, our armored troops quickly swept across the French defense line and artillery positions in other areas. Although the French cannons were hidden, they had no choice but to targets that appeared in front of them. At that time, our army can cross the river from other areas at the same time!" After saying that, Chen Tian renewed another cup of coffee. It is said that in addition to refreshing the spirit, coffee also has a good effect on maintaining its figure.

"The French Seine defense line extends hundreds of kilometers north and south. Whether it can ensure oil and ammunition supply is very critical!" Orger's question was very accurate, and then he gave an answer that was not the answer:

"So we need to set up as many pontoon bridges as possible on the Seine River, and we must clear the French army in the city of the west bank of the Seine River as soon as possible!"

Hoffman asked Chen Tian for his opinion with his eyes, and then spoke: "According to a rough calculation, we need to set up at least twenty floating bridges that can pass through one tank or armored vehicle at a time. All of this is done under the noses of 30,000 French troops, hundreds of heavy machine guns and 200 various artillery guns. Apart from tank guns and small-caliber infantry guns, we have no other artillery fire cover!"

"God! This is really a crazy plan!" Orger was surprised after hearing this, "Are our infantry ready to build a pontoon bridge in thick armor?"

Hoffman shook his head.

"Col. Do you have any different opinions on how to build a pontoon bridge?"

Guderian raised his head, and what caught his eye was Chen Tian's expectation.

"My Prince, I am not an expert in this field. As far as I know, floating bridges are mainly composed of bridge piles and bridge decks. Bridge piles are generally divided into two types: floating bridge piles and fixed bridge piles. It is more suitable to use floating bridge piles such as ships in places with deep rivers. In places with shallow rivers, floating piles, wooden piles, stone piles and even fixed piles such as human piles. Bridge decks are generally divided into wooden beam wooden board bridge decks and steel beam wooden board bridge decks. Infantry and small cannons crossing the river to use wooden beam wooden board bridge decks and any bridge piles. Heavy artillery and tank armored vehicles need at least steel beam wooden board bridge decks and floating bridge piles with sufficient buoyancy or fixed bridge piles."

After Guderian finished speaking in one breath, Chen Tian couldn't help but laugh in his heart. This guy was actually not an expert. He wrote a paper "On the Quick Crossing of the River in Tanks and Armored Forces" at the Armored Academy. Chen Tian praised the ideas and operation details.

"Col. Hoffman, let's introduce the river we are going to cross!"

Hoffman nodded, "The Seine River is the fourth largest river in France. It flows into the central area of ​​Paris from the southeast of Paris and goes to the sea from the southwest direction. The Seine River is 12 kilometers long in the downtown area of ​​Paris, with a widest river surface length of 190 meters, and a narrowest river surface length of 25 meters. The average width of the river surface is 100 meters, with a depth of 3-4 meters. The river water flows slowly, and the bottom of the river is basically full of hard rocks."

"Because the river is wide, it is impossible not to use piles. We don't have enough ships in our hands. Even if there are, the French army can destroy them one by one at such a close distance, so there is no need to consider floating piles. It seems that we only have the fixed bridge piles left. Colonel, I'm right!" Chen Tian turned to Guderian after saying that, and he just nodded gently, as if he was still thinking about his own ideas.

"Then the question is how to lay what kind of bridge piles under the dense firepower of the French!" Chen Tian said in a stressful tone. He was still constantly improving his ideas in his mind, and the original methods were constantly replaced by better methods.

Perhaps these three people may not be able to come up with a better solution, Chen Tian thought so.

"Use the firepower of the entire legion of tank guns, mortars, infantry guns and machine guns to suppress the French firepower on the other side, and then use wooden piles and steel piles to quickly build a floating bridge!" Hoffman's opinion was not creative.

Perhaps the mind became active under the stimulation of fragrant coffee. Orger's suggestion made everyone ashamed, "Use the existing railway line in Paris to let the train drive to Seine, and use the train's body to cross the river as a pontoon!"

This method may sound exaggerated, but if you think about it carefully, it is possible to implement it.

Hoffman quickly calculated, "There were originally five railway bridges on the Seine River, which means there were five railway lines leading to the riverside. The river surfaces of these five places were not too wide, so even if the train could not rush to the other side, the remaining distance would not be too long. The passenger compartment of the train was almost 3 meters high, so it was also appropriate to use it as a bridge pier after sinking to the bottom."

"This method cannot be regarded as the main way to cross the river. After all, the state of the train after it rushes into the river is difficult to predict. Perhaps it is just rushing to the center of the river, and perhaps the carriages will be folded together, and infantry can barely pass through it, but it is unlikely that the vehicles will be. Despite this, I think we can still use this method as an auxiliary way to cross the river, which can greatly attract the attention of the French!" Chen Tian imagined the scene of a series of trains roaring into the river, which must be very spectacular.

"General Orger's idea gave me a big hint. I think we can use a more relaxed and stable method!" Guderian said slowly, "Car!"

"car!"

Chen Tian nodded, Guderian's idea coincided with his own. Chen Tian's initial idea was to use the future mechanical engineering troops to build a floating bridge, but after thinking about it carefully, firstly, the current technical conditions do not allow it, and there is no way to make so many new things in a short period of time. He also considered the method of using the assault squad to sneak into the enemy's back, but now there is no way to transport a large number of troops across the Seine defense line to the enemy's back, and the defense of the French artillery positions must be very strict. Even if an artillery position is placed in an infantry battalion, it will be very difficult for the assault team to destroy it, not to mention that the French artillery positions are hidden and numerous. So Chen Tian thought of cars.

The most primitive method is to use a car to transport earth and stone to create an artificial embankment on the river surface. However, this method is slow and laborious, and completely blocking the river will inevitably cause the river to spread to both sides. Therefore, Chen Tian thought of sacrificing the car as a pier for floating bridges.

"I think it's possible to load a lot of earth and rocks on the car, then drive them into the river as bridge piers, and then build a bridge deck on it. Such a 50-meter-long pontoon bridge only costs about 15 trucks, and 20 pontoon bridges are 300." Guderian roughly explained his idea.

"But can cars go so far? I mean the first few cars are fine, but what should I do if the areas close to the opposite shore?" Orger asked in confusion. It seemed that he didn't understand the idea of ​​using a car to build a bridge.

"You will know this at that time! In addition, I have a better way than installing soil and stones. Colonel Hoffman, you go and ask the soldiers to modify 300 trucks. I will draw a sketch for you in detail how to modify it. At the same time, we use rails and wooden boards to make a batch of steel beams and wooden boards. In addition, we also need a large number of smoke bombs, the more the number, the better. Try to complete all this within 5 days!" Chen Tian's brain was running quickly, and his plan was gradually clear. Now there are only some details left to be further improved.

"Yes!" Hoffmann didn't understand it very much, but everything would be answered in 5 days.

In the next few days, the East Prussian Legion's station was busy and busy, and Guderian went to the banks of the Seine for observation and measurement, selecting all the areas suitable for crossing the river. In the end, Chentian selected 20 of the areas with a river width between 30-50 meters as the breakthrough location.

Almost every night, Chen Tian and Guderian fought at night in the command center, carefully pondering every detail of the combat plan until it became a foolproof plan.

On the other hand, Orger also directed the soldiers to repair some damaged railways in Paris, and the trains specially prepared for this attack slowly entered the downtown area of ​​Paris on the fifth day.

When the sun sets on the fifth day, Hoffman has prepared all the special trucks and bridge boards.

In Chentian's opinion, everything is ready now, and even the east wind is not short of it.

If it was a foggy night, then everything was perfect.

Falkenhein walked to the window of the command room. It seemed that it was a starry night. He was about to enjoy the beautiful scenery when a consultant walked aside and reported:

"Chief of the General Staff, the Prince of East Prussia's phone number!"

"Yeah!" Falkenhein quickly walked to the phone, "Yeah, yeah, I get it! OK, that's it!"

After putting down the phone, he turned to his staff, "ordered the armies to launch artillery bombardment on the French positions on the other side and set out to prepare to cross the river, but without my order, no soldiers or soldiers were allowed to cross the river!"

"yes!"

When the rumbling cannon sounded across the earth, Chentian's troops, which had already quietly entered the downtown area of ​​Paris, began to move towards the riverside.

The sound of cannons in the distance well covered the mechanical sound of the friction between the vehicle engine and the tracks. Walking at the front of the legion were some strange-looking trucks. They carried large shells like turtles. To be precise, their carriages were converted into a large square box. These iron boxes, plus the chassis, were 4 meters high. They were welded from steel plates, reinforced with steel pipes or steel columns, and there were also a lot of earth and stones on the lower part of the box.

This strange convoy stopped on a street in front of the river bank. Soon after, large streams of white smoke floated from the upper stream, and the river surface suddenly filled with fog.

Woo...

In the area where the railway bridge was originally built, the sound of the train's whistle suddenly came from the fog.

"Didn't the railway bridge be completely blown up?" French soldiers on the other side were puzzled.

Suddenly, a huge sound came from the river, as if a giant whale was slapping the water. Next was a huge and dull explosion. The sound was completely different from the bomb explosion, just like...

"A train rushed into the Seine River, and the boiler of the locomotive exploded!" French soldiers on the other side quickly picked up the phone and reported to their superiors.

In the fog, the train was like a winding snake looming across the Seine River. The locomotive was less than 10 meters away from the west bank.

The French had not figured out what was going on. The fog on the river surface was getting thicker and thicker, and the distance of sight had dropped to several meters. The world here seemed to be swallowed by the fog, and even the "big snake" quietly disappeared into the thick fog.

General Simon, the French commander of the Paris area of ​​the Seine River defense line, was already busy. It was a strange night for him. When other areas of the defense line were bombarded by German troops, the defense line in the city was still calm, but he soon discovered heavy fog here for no reason. Then his soldiers reported that trains rushed into the Seine River in five areas, and two of them actually hit the bank of the river.

Ximang quickly realized that this must have been deliberately made by the Germans.

"Damn Germans, they actually came up with such a despicable way to cross the river!"

Ximang picked up the phone angrily, "Hey, get me the artillery... Major Vassel? Yes, I am General Ximang, I order you to shell the river surface of these five areas, the coordinates are... what? There are many precious buildings there, go hell! Do you want to spend the rest of your life in the German prisoner-of-war camp? Bomb me, bombard me violently! If there are any losses in our buildings, everything will be recorded on the Germans! Yes, do it well!"

After putting down the phone, Ximang was still not relieved, so he decided to transfer some of the reserve team to those areas where something happened.

"Order the defenders from all over the world to monitor the movements of the Germans and report them to me immediately if similar situations occur!"
Chapter completed!
