Plan H, designed by Germany during World War II, introduces the Yellow Plan and the Sea Lion Plan of

In order to be in a hurry, the designer refers to a large number of references in the design and designs at the same time"Bismarck"Level. There are also many battleship experts who believe that Germany was no longer capable of advancing at the same time. The second batch of shipbuilding plans belonging to Germany and the Zeppelin aircraft carrier sailed a batch of specific performance and ** on the World War II military network to find it During World War II, Germany was ready to build"Hindenburg.

The Yellow Plan was basically a repetition of the tactics of Germany in World War I, taking the Dutch, Belgian route and marching to the north-west. Then a south-west assault advance to the heart of France. As opposed to Manstein's tactic of raiding directly from the Ardennes Forest.

With this yellow plan, Germany has very little chance of winning, and Britain and France can repair Germany again in the same way.

The Sea Lion plan, in which Germany launched a cross-sea attack on the British mainland from the occupied European region, actually failed.

After the capture of Poland by the Germans, according to the established order of strikes, the next target of attack would be Western Europe. At this time, what the Germans needed to solve was the choice of the timing of the invasion and the direction of the main attack; The Allied forces needed to accurately determine the timing of the German invasion and the direction of the main attack, and coordinate the positions of all parties to organize a strong defense. On February 13, 1940, Hitler had a long talk with General Jodel, advocating the surprise use of Sedang as the main direction of the German army.

On 17 February, Hitler summoned Manstein. General Manstein elaborated on his plan: to cross the Maas (Meuse) on both sides of Sedan with a strong Army Group A through the Ardennes Forest, and then through northern France to Abbeville, to divide and encircle the Anglo-French Flemish group in coordination with the right flank.

Hitler accepted the plan. On 18 February, Brauchitsch and Halder, in their talks with Hitler, came up with a plan that went further than Manstein – a decisive breakthrough on the Maas River between Dinan and Sedan . Hitler agreed, stressing the need to quickly prepare for a French attack from behind the Maginot Line.

Accordingly, on February 24, the German Army General Headquarters issued a new operational pre-order for an offensive against Western Europe, still codenamed the "Yellow" scheme.

On April 9, 1940, the Germans occupied Denmark in just four hours.

H39 is a total length meter, a width meter, a standard displacement of 53,000 tons, and a full load displacement of 62,496 tons.

The firepower configuration is 4 twin 406mm main guns, 6 twin 155mm secondary guns, 8 twin 105mm anti-aircraft guns, 8 twin 37mm anti-aircraft guns, 6 quadruple 20mm anti-aircraft guns, and two triple 533mm torpedo tubes.

In 1933, Hitler became Chancellor of Germany, and the future of the German Navy was becoming increasingly clear. Hitler promised the Commander-in-Chief of the Navy, Admiral Raeder, that the Navy would take precedence in a fair distribution in the future plans for the building of the army. This won the support of Raeder and the entire Navy.

Raeder then developed a naval construction plan, codenamed "Z", which focused on building a surface fleet large enough to fight the British main force at sea within 8 to 10 years. It included 10 large battleships, 3 battle cruisers, 8 armored cruisers, 4 aircraft carriers, 44 light cruisers, 68 destroyers, 90 torpedo boats and 249 submarines.

Britain and Germany signed the Anglo-German Naval Agreement on 18 June 1935. The treaty mainly stipulates that the total tonnage of German naval vessels shall not exceed 35% of the total tonnage of naval vessels of the Commonwealth countries stipulated in the Washington Naval Treaty and the London Naval Treaty.

In the case of submarines, Germany has pledged that the tonnage of submarines it retains does not exceed 45 per cent of the total tonnage of submarines of the Commonwealth navies.

It is generally believed that the Anglo-German Naval Agreement legally lifted the restrictions on German naval armaments in the Treaty of Versailles, and Germany began its own shipbuilding program under Raeder's leadership. The previous shipbuilding program was the 1935 plan, and then Raeder proposed the 1938 plan, the "Z" plan, due to Hitler's assurances that he would not use the navy to enter the war in 1946. The 1935-1938 plan was based on the Anglo-German Naval Agreement, which Raeder had always considered to be a blueprint for a strategic vision for the rebuilding of the German navy, rather than a plan for a British arms race.

Britain was very appreciative of the Anglo-German Naval Agreement, and the admiral Betty even openly praised the spirit of the Germans in Parliament, saying that it was gentlemanly to take the initiative to maintain an inferiority over Britain. Don't you know that the Germans jumped out of the restrictions imposed on them by the Treaty of Versailles and vigorously carried out the construction of the navy. Because judging from the strength of the German Navy before the signing of the agreement, due to sanctions, there is still a very huge space for the so-called 35% of the British Navy, which can allow the Germans to develop all the naval forces that can be developed with peace of mind, and the British did not take the German plan for 1935-1938 into account.

For even if these plans were to be carried out successfully, the Germans' naval strength would be far from reaching the ceiling set out in the Anglo-German Naval Agreement, and the British would only carry out the construction plan according to their own guidelines. In fact, most of the "Z" plan was not implemented, because Hitler did not act according to his promise to Raeder and started the war in advance, and Britain could not talk about a corresponding plan for the "Z" plan, even if the "Z" plan was fully realized, it would not be until 1948 (the Z plan was scheduled to be completed in 10 years, provided that there was no war), after which Britain would still maintain absolute naval superiority. Therefore, the British did not strictly correspond to the shipbuilding plan of the "Z" plan, but the shipbuilding plan of the United Kingdom before the war was aimed at the United States, the later ally, and the typical example is that the "King George V" class was designed for the new American battleships, and had nothing to do with Germany.

1935 Saar returns to Germany after a referendum.

1936 Hitler tears up the Versailles Agreement.

1936 The German Intervention Forces enter the Spanish Civil War, triumphant in 1939, establishing Spain as an ally of Germany.

On September 1, 1939, the White Plan Poland refused to return the Danzig Corridor, Germany launched a blitzkrieg against Poland, Britain and France declared war on Germany on the 3rd, and at the same time declared no war on the Western Front, the Soviet Union took the opportunity to attack Poland, and Poland was finished within a month.

Weseruebung Visse exercise, the German attack on Denmark, took two hours. Both Britain and Germany wanted to preemptively occupy Norway's ports, heavy waters, fleets, etc., and Germany struck first, and in June the airborne troops fully occupied Norway.

The Yellow Plan, in which Germany attacked the Three Low Countries in order to bypass the Maginot Line.

The Red Plan, in which Germany continued its attack on France, was victorious two weeks later. Germany then occupied the northern and western coasts of France, with Vichy** taking over the rest, while French overseas mandates such as Lebanon, Syria, and Madagascar largely supported the Free France in exile.

Italy attacked Greece and Albania, but was defeated and lost its own territory, and asked Germany for help, which swept away the Balkans, but lost a precious summer Barbarossa plan for a month. Yugoslavia was cut into ten pieces, and the independent ones were all puppets.

In February 1941, Rommel left for Africa.

Yugoslavia surrendered on April 17, 1941.

On April 6, 1941, German troops entered Greece, entered Athens that month, and landed on the island of Crete.

Germany went to war against the Soviet Union.

Then turn south to seize the Ukrainian granary, losing a good opportunity to attack the fortification, giving the Soviet Union time to prepare for the defense of the city.

In the winter of 1942, when Germany's expansion reached its peak and the end of its strong crossbow, after the surrender of the Sixth Army, the Eastern Front collapsed, and then began to decline step by step.
