Bordeaux is currently the most fierce place in the whole of Europe, in this wartime capital of France, the two sides have fought for two years in the vicinity, at least more than 3 million people, lying here forever, the most important thing is that there are more than 1.5 million wounded, of which 8 percent are the Entente, it can be said that the blood of millions of people, this defense line is dyed blood red, shells come over, stirring up the soil, and even with the color of dark blood.

From the French troops withdrawn in Paris, and temporarily established a foothold in Bordeaux to the present, before and after two years, I don't know how many battles have taken place in Bordeaux, and even the fragments and bullets of artillery shells, laying Bordeaux in a thick layer, in large-scale offensive and defensive operations, using 1 million, even 2 million, hundreds of thousands of cannons, 200,000 or even 500,000 shells a day, those high ground in the front of Bordeaux, there are a lot, all of them are flattened by artillery fire, In the long-term battle, the soldiers on both sides are accustomed to this kind of shelling, maybe under the premise of firing 10,000 cannons, they can still eat and sleep as usual, as long as they hide in the anti-artillery hole, it is OK, the anti-artillery hole built with steel and a large amount of wood, there is at least 3 meters thick soil layer above, the artillery fire can not affect at all, at most there is some vibration, sprinkle some dust.

From this point of view, less than 50,000 shells cannot have much impact on Bordeaux's position, but this shelling is a naval gun, it's another matter, army artillery fire, even if it is a 220 mm heavy gun, his shells are not heavy, dozens of kilograms will reach the sky, but naval artillery, especially 15-inch naval artillery attacks, it will be fun, itself is only for the army artillery fire anti-artillery holes, simply can not withstand such artillery attacks, besides, Scheer also chose a relatively narrow area, If this shelling falls on a place less than 3 kilometers long and 6.5 kilometers wide, even if it is army artillery fire, the density is quite good, not to mention the naval guns.

On less than 20 square kilometers of land, 50,000 shells fell, almost an average of 30 square meters, just one shell, the army's artillery fire and the navy's artillery can be compared, the army's largest naval gun, I am afraid it can only be the navy's smallest main gun, or the light patrol level, the heavy patrol artillery is more than 10 inches, the battleship is at least 11 inches of artillery, and even the pipe body double, shell weight and many other aspects, are far inferior.

Every 1 inch increase in the caliber of the artillery, the destructive power and weight of the artillery will rise dramatically, if it is also a cone, the outermost one, will always be the largest circle, plus the length of the naval gun, far longer than the ordinary army artillery, on the battleship, also take into account the weight and many other problems, but for the pipe body double, it is as much as possible, so in the case of the same caliber, the navy is always longer than the army, and the power is much greater.

The army cannot make the length of the artillery too long, and everyone knows that the longer the barrel, the longer the acceleration time of the shell, and in this case, the greater the speed and power of the artillery. However, the army must take into account the transportation effect and balance, if the barrel is too long, it will be top-heavy, and it must be counterweighted, which is equivalent to fearlessly increasing the weight of the artillery, before the popularization of land, self-propelled artillery and roads, the weight of the artillery is one of the general factors of the artillery, and the weight exceeds the standard, which will bring a lot of unnecessary trouble to logistics and marching, and even a rainstorm attack is enough to cut off the possibility of artillery movement, and the artillery that cannot be moved is a nightmare for a war.

In the European war, it was steel, starting from the rifles and machine guns of the infantry, all the way to artillery, and the artillery below the regimental level could not be transferred on a large scale, all on a position, but the strategic artillery above the regiment, even if it was the dominant Germany, it was impossible to guarantee that all the strategic artillery fire would not be attacked by sneak attack, under normal circumstances, the strategic artillery fire must be transferred for a maximum of half a day, in this case, the use of naval naval guns, which is at least twice as heavy as the ordinary army firepower, is an absolute nightmare.

But the navy, there is no such thing, what is heavier than the battleship hull itself, a heavier counterweight, how long the barrel can be, how long the barrel can be, so generally speaking, for the same caliber artillery, the army artillery is not as strong as the naval artillery, not to mention more than 11 inches, even 15 inches of artillery, especially the 15-inch gun, the weight of more than a ton, the use of Chinese armor-piercing shells, the weight is increased by 30%, under the powerful power of naval guns, At a speed of more than 600 meters per second to hit the fixed fortifications, the steel can penetrate about one meter, not to mention the thin, only 3 meters thick soil layer, even the support below has no way to resist, once the one-ton artillery, hit the anti-artillery hole, the fun is great, just the shock wave is enough to kill people, not to mention the steel caused by the explosion and distortion, torn apart by the attack of the naval gun, a quick blow in the enclosed space, all the people hiding in the anti-artillery hole, almost immune, it is better to hide outside.

During the First World War, on the front line of large-scale trench warfare, there was no large-scale naval artillery covering attack at all, and the Allies also made the wrong choice, they should have scattered their troops in outdoor trenches, rather than in anti-artillery holes, and now, they had to wait for the roll call of naval guns, completely depending on luck, only if the shells did not fall on the head, it was possible to survive, once the shells fell on the head, almost more than seventy percent of them would definitely die.

At a distance of more than 15 kilometers, the naval artillery does not have much accuracy, and Scheer does not intend to strike accurately, 50,000 shells, if the strike is accurate, the lethality will be greater, just like China, with the help of the computer aiming system, the accuracy of the strike on fixed targets is as high as more than 9 percent, and in addition to the accurate reconnaissance results brought by the reconnaissance plane, it can easily kill the place where the army is concentrated.

However, this is the second-generation sighting system, and the accuracy of the calculation is much higher than that of the first-generation one, and this one of the Scheer fleet has also gone through a lot of turnovers, and the results of 9 battleships alone are very good, and the hit rate of fixed targets can barely reach more than 5 percent, but the others are added together, and it is not good.

Dealing with Bordeaux like this, a defense line that stretches for hundreds of kilometers, a super giant defense line that concentrates millions of people, even if it is only a concentrated attack to one point, it is not something that 9 warships can threaten with less than a hundred naval guns, although these are all naval guns of more than 15 inches, and one shot may be compared to other main guns hitting two or three guns, but the number is too small and the deterrent power is insufficient. This was quite a blow to the offensive and soldiers that spread all over the mountains.

In the selection of the focus of the artillery bombardment, on the outside of Bordeaux, the nearest line of defense with the German army is on one side, an area 6.5 kilometers long and 3 kilometers wide, this area is at the forefront of the battle between the Central Powers and the Entente Powers, and is the salient of the Entente Powers, because the Entente Powers are often suppressed in the war against Germany, and to be able to obtain this salient not only consumes a lot of the strength of the Entente Powers, but also the most elite troops. On the front were 12 divisions of German troops, almost 250,000 men, also the elite troops of Germany. In order to deal with such a strong German army, the Entente put down 550,000 men and 40 divisions, which can be said to be one of the densest and fiercest places in the entire Bordeaux battlefield, and in the past three months, there have been as many as 100 battles above the division level in this area, almost once a day on average.

The plane has become the basis of this success since the beginning of this naval operation, and Scheer knows very well that if there is no reconnaissance plane, he will never be able to command the operation so easily, and the reconnaissance plane can clearly inform him of all movements within 400 kilometers of the surrounding area, and with the help of the radio system, he can clearly determine the movement between the enemy and us, otherwise, a fleet must leave a part of the reserve force to deal with the sneak attacks and attacks that may come at any time, which is exactly what the Entente lacks.

Scheer believes that as long as this advantage is continued to be expanded, reconnaissance, artillery, and radio, Germany will be like a tiger with wings, and the application of new technologies will be so great for the improvement of the battle, and Scheer is also well-informed about himself, but the changes in the naval battle almost dizzy him, and he even felt that when he was in Southeast Asia, with the help of robbery dividends, the 8 Bavaria-class ships ordered in Southeast Asia were a bit reckless, and if they were replaced by 6 Fantasy-class, even if they would pay more money because of this, it was worth the money.

It is precisely because they know very well the distribution of forces here, and Scheer knows, even if their high seas fleet is exposed to the frontal battlefield, it is impossible for the Entente to retreat this line of defense, because it has enough geographical advantages, backed by a high ground, and has been operating for many years, the defense is quite stable, and as a salient, there are three targets that can be attacked, which is one of the few places where the Entente is more active in the entire Bordeaux battlefield.

However, the location of this place is quite bad, only 10 kilometers from the coastline, the location of the Scheer fleet is 3 kilometers outside the coastline, 13 kilometers away, most of the main guns and some secondary guns of the high seas fleet have this range, at least 8 inches or more can be attacked here, this is a nightmare, the solid position depends on the comparison, here is the focus of the attack, 50,000 rounds of large-caliber naval guns, fell on the entire defense line of Bordeaux, 100 square kilometers, or even 50 square kilometers, this is nothing, However, in an area of 20 square kilometers, this is quite dense, and the most important thing is that the Scheer fleet did not deliberately target certain targets, but covered the attack, so that according to the probability, almost every place received the same artillery fire, and this place was almost destroyed.
