Of course, this summary of East China** also contains a lot of its own private goods, and the content of these 5 points is actually aimed at Germany's gains and losses in World War I, which is equivalent to a wake-up call for Germany.

The first distinction between land and sea is related to Germany's grand strategy for future wars. If China is a complex country on land and sea, and needs to develop both a navy and an army, both of which are indispensable, then Germany is a typical continental country, in fact, there is no need to develop a large navy at all, and it is only necessary to retain a navy sufficient to protect its coastal defense. Germany's development of its navy at this time, and even the fact that it did not hesitate to challenge Britain, was largely due to Wilhelm II's preference for the navy and his envy of the British navy, which had little to do with Germany's national strategy and interests.

This does not mean that the mainland countries cannot develop their navies, but Germany first of all has two powerful land rivals on the European continent, France and Russia, and for the time being, there are no huge overseas interests to protect, and the contradictions with Britain are not completely irreconcilable. Although it was true that the Germans had built a fleet second only to Britain and fought the largest naval battle of battleships in history, on the whole, the German navy could not be said to have contributed nothing during the entire war, but compared with the huge cost of building the navy, it was really worth the loss. Therefore, some people in the old time and space thought that before World War I, Germany might as well give up the development of the navy and concentrate all its resources on the army, maybe the result would be better.

In fact, during World War I, the German Navy could still play a great role if it was properly used, such as the infinite submarine warfare launched by the German Navy, which did exert tremendous pressure on the Entente, but it was necessary to clearly distinguish the priority relationship between the navy and the army.

Allowing the country to enter a period of war as soon as possible is a reminder to Germany of the protracted nature of future wars. In modern times, before the First World War, there were basically no long wars in Europe, and the Thirty Years' War and the Napoleonic Wars lasted for a very long time, but they were non-stop, not continuous. Even the Franco-Prussian War, which was a relatively large-scale war, was only fought for 10 months, and in the first two months of the war, the Prussian army defeated the French army at Sedan and captured the French Emperor Napoleon III.

In the old time and space, before the start of World War I, all parties involved in the war were generally unprepared for the long-term and arduous nature of this war, and according to the previous custom, the time of the war was set at half a year to a year, so at the beginning of the war, no one implemented a wartime plan in their own country, so it is known that the war was fought for more than four years. If Germany had been able to implement a wartime system at the beginning of the war, with a plan to control resources, it would have been able to hold out longer, if not in the end.

The third and fourth articles are aimed at the offensive and defensive mode of the land war of World War I. The main mode of war of the First World War was trench warfare, which favored the defending side, so the war entered into a long war of attrition. However, this form of war is obviously not to the detriment of the side of the Allies, which is weaker in terms of overall strength. This is to remind Germany that it was aware of this form of war earlier and made targeted preparations.

Although in World War I, air combat could not determine the direction of the final war, but there was still a fierce air struggle, and a group of mythical pilots were born, the most typical representative of which was the famous red baron. Therefore, in future wars, whoever can take the lead in air combat will be able to gain the initiative in the war.

Of course, whether these summaries or reminders, they do not necessarily make Germany win in World War I, because the biggest weapon in trench warfare - armored vehicles, East China has always kept it secret from Germany. Therefore, it can increase Germany's war capability and fully exploit Germany's war potential, at least so that Germany can hold out for a longer time, and if Germany can recognize these problems very early and improve them, it is not impossible to end up in a draw. Whether Germany can grasp these meanings is another matter.

Although the German General Staff did not know about the private goods carried by East China, it still spoke highly of this summary, believing that East China had basically thoroughly understood the lessons and lessons of the Far East War, and that there were many places where there were great similarities with Germany's cognition, and that it also had extremely important reference value for Germany.

However, judging from the German classified documents released after the First World War, Germany's experience from the war in the Far East is very different from the original intention of East China.

In fact, the German Army's view on the dispute between the navy and the army is that there is no need to develop a large navy at all, as long as the coastal defense force of the foundation is maintained, Germany should still concentrate resources to further strengthen the army, after all, in the future war, the German army is very likely to face the two strong opponents of France and Russia at the same time. However, the development of a large navy is a decision of His Majesty the Emperor, so no one can have any objections.

As for the second point, Germany is the most insensitive, not only because Germany has never fought a long war, but also because at this time Germany has formulated the Schlieffen plan for a quick victory in the event of a war against France and Russia at the same time, so Germany has indeed never thought of fighting a long war, and of course it will not think of entering a wartime system as soon as the war begins.

As for the defense of the third trench, Germany attaches the most importance to it, but Germany's focus is not on the enemy's trench defense, but on using the trench defense to deal with the enemy.

Originally, according to the Schlieffen plan, the entire German combat force was divided into the eastern front against Russia and the western front against France. Among them, there are 79 divisions of the troops on the western front, while only 10 divisions are set up on the eastern front, with some local troops interspersed. The ratio of forces on the eastern and western fronts is roughly 1:8. The Western Front was divided into two wings, 68 divisions on the right flank and 11 divisions on the left, with a ratio of 1:8, and part of the left flank was in the center of Verdun, which was the northwest entrance to Paris (only 135 miles from Paris) and the center of gravity of the French defense system against Germany. The rest are deployed along the 240-kilometre-long Franco-German border. The right wing on the Western Front was the main force of the German main force and the key to Germany's victory in the war.

Once the war began, the German troops on the Eastern Front, with their small forces, echoed the Austro-Hungarian army and pinned down the Russian army, with the aim of confining Russia to the East Prussian border. The task of the left flank of the Western Front was to lure the enemy and defend against the attacks of the main French forces. At the same time, the right flank assembled on the Western Front rotated southwest with the Verdun area as the axis, passed through Belgium, a neutral country in Europe, entered France from the Belgian border, and surrounded Paris from the north, west, and south after crossing the Belgian plain and sweeping the French coast, and then eastward to outflank the main force of the French army. Strive to completely defeat France within 6 weeks, force France to surrender, and then rely on Germany's perfect railway system and strong railway capacity to turn to the eastern front to deal with Russia.

However, whether it is on the Eastern Front or on the left flank of the Western Front, no one knows whether the strength of just over 10 divisions will be able to withstand the offensive of the Russian army and the French army, and adhere to the six weeks required by the Schlieffen plan. Of course, the Schlieffen plan was completed in 1905, when the total strength of the German Army was only about 90 divisions, but no matter what changes occurred in the strength of the German Army after that, according to the Schlieffen plan, the distribution ratio of forces on the left and right flanks of the Western Front on the eastern and western fronts should remain basically unchanged.

However, the changes on the battlefield are changing rapidly, and who can guarantee that the German army will definitely be able to capture Paris within six weeks and force France to surrender? What if it takes eight weeks, or even longer! Will the small number of troops on the left flank of the Eastern and Western Fronts of the German army still be able to hold out at that time! Therefore, Moltke Jr., the newly appointed chief of the General Staff, revised the Schlieffen plan and increased the proportion of troops on the left flank of the Eastern Front and the Western Front, but this naturally weakened the strength of the right flank, which was the main force of the German army.

And the strong defensive capability of the trench defense gave Germany the weight to ensure the success of the Schlieffen plan. Without increasing the ratio of forces to the left flank of the Eastern and Western Fronts, it was also possible to ensure the defense of the left flank of the Eastern Front and the Western Front.

In fact, during the war in the Far East, the German military observer group stationed in the People's Army noticed the defensive power of trench defense, and after returning home, strongly suggested to the German General Staff that the tactics of trench defense be seriously studied.

To this end, the German Army also conducted a special test, under the command of members of the Military Observer Mission, according to the trench model of the People's Army, to build a nearly 1,000-meter-long defensive line, guarded by a regiment of troops, and dispatched a division to attack.

Under normal circumstances, when the ratio of the strength of the attacking and defending sides is 1:4, it is generally 2 or 3 days, and it will not exceed 5 days at most, but it takes 9 days to defend the position before it is breached, and the casualty rate of the attacker is 19%, which can be regarded as heavy casualties in the war. Moreover, according to the members of the Military Observer Mission, the layout of the positions was not perfect, after all, they were only drawing on the gourd, and they did not know much about many details of the trench defense, so they could only add their own understanding, but these understandings were not necessarily correct.

But even so, this result still shocked the German General Staff, and if this kind of trench defense was applied to the defense of the left flank of the Eastern and Western Fronts in a future war, it would undoubtedly greatly increase the chances of the success of Schlieffen's plan.

Count Schlieffen, who had already retired, became acquainted with this result, and wrote a special letter to the General Staff, emphatically pointing out: In the event of war, the right flank of our army must not be weakened.
