Hitler had high hopes for the intelligence system controlled by Himmler, but in fact the intelligence system of the Germans was already in tatters by this time. Compared with the deep-rooted British intelligence system, the deep-pocketed American intelligence system, and the Soviet intelligence system, which upheld the principle of catching mistakes and letting them go right, and grew up in decades of struggle between blood and fire, they are increasingly inadequate.

However, this is only a superficial phenomenon, and the real more fatal reason is that after several years of war, the ideals of the Nazis, or rather the ideals of fascism, have been shattered. Intelligence work requires the spirit of self-sacrifice the most. Don't think that doing this is like in a Bond movie, where beautiful sports cars are rotated. This profession, as a certain sect leader said in a certain unfinished book, is full of pressure, heavy rules, and great sacrifice. If necessary, it is likely to be ruthlessly sacrificed for a purpose. Just like the "Lisa" who successfully changed the fuse for the gun drive motor of the "Lindemann" battery, this person's performance is not outstanding, but her superiors will not hesitate to betray her to the Germans in order to achieve the goal of deceiving the enemy, and then kill the person who was ordered to betray her as a "traitor" in order to further win the trust of the Germans. Entering this profession is equivalent to entering the ghost domain.

And this profession requires the high ability of its participants. And if a person with such ability is selfish, why should he engage in such a business? With such ability, why is the final result not better than being an agent? Just like Guo Ruhuai in the dispute between tg and {a}{本} ~ novel yb][dukmt, he was born in the Whampoa Military Academy, and was very valued by Chang Kaishen, coupled with outstanding ability, he was promoted to the director of the Lieutenant General Operations Department of the KMT National (River Crab) Defense Department. The information he provided played a considerable role in TG's defeat of KMT. However, after the liberation, the treatment he received was only to go to the Nanjing Military Academy as a teacher. So most of the top agents in history are true idealists.

The British and Americans had a "Defend Liberty" banner that could be used to entice those idealists to fight for; The Soviets had the banner of "**", "struggle for the liberation of all mankind", which could also inspire a large group of idealists, even a group of German idealists. For example, the famous red spy king Sorge is a German. This is all the more true of the "Red Choir", which is active in Germany.

In the beginning, the Nazis also had a banner with the words "nation and order" written on it, and they used to fascinate many people. But as the war dragged on, the Nazi and fascist propaganda about the "high race" and "orderly life" was shattered by the facts. Along with it was the German espionage capabilities. In the thirties, the Nazis even had a large group of supporters in the United States, but now, the boys who were influenced by the Nazis are now wholeheartedly trying to kick Hitler in the ass.

Some of the "spies" developed by the Nazis in Britain also had such problems. When they found out that they had been deceived by Nazi propaganda, some of them began to cooperate with MI6 in anger. They became so-called double agents. Now, in order to get information about the "First American Army Group", the Germans gave instructions to these people, the result of which is naturally predictable. The German intelligence system began to receive some carefully prepared information from the British, most of which was scattered, and there were contradictions between many of them. But that's exactly what this kind of intelligence necessarily comes in. Through the hard work of German intelligence agencies, the situation of the "First Army Group of the United States" was gradually pieced together. The strength of this army put all the German generals under pressure.

While the Germans were feeling pressure for the illusory "First Army Group of the United States," the Allied preparations were also well underway.

The efficiency of the attack on the beachhead by the 21st Attack Aircraft Wing is increasing over time. Now, the P/A-38s of the two squadrons have been able to stably compress the time from the landing of the shells to the time of dropping the bombs to about 4 minutes, and the accuracy of the attack has been guaranteed to a certain extent, at least, the situation of the bombs falling into the queue of their own people is no longer possible.

Not only are preparations for the 21st Attack Aircraft Wing progressing steadily, but the work of other departments is also progressing smoothly.

In all operations, landing operations are almost the most complicated one, and they have to take into account the most factors, such as what tides, what weather, what landing sequence, and what supply methods, all of which require serious preparations. Due to topographical and hydrological constraints, the suitable sites for landing are quite limited, so do not assume that you will be able to find the so-called "unfortified areas of the enemy". When you get to the beachhead, you're sure to be under heavy fire from enemies hiding in the sturdy hours. What's worse is that the first round you will be filled with light infantry without heavy weapons.

In addition, logistical supply is also a big problem, and in previous US landing operations, ships loaded with certain supplies were sunk, resulting in the dilemma of the lack of some important materials for the entire army. So the Americans summed up the practice of dispersing all kinds of materials and loading them on ships to ensure that each ship docked had all kinds of necessary supplies. However, this approach undoubtedly also increases the workload and complexity of logistics.

Hydrology is also a challenge. Some of Normandy's beaches already had reefs, and the Germans made a large number of artificial reefs out of concrete piers. All these things will seriously threaten the security of the landing fleet. In order to deal with these things, the Allies used a large number of divers to approach the enemy's coast by submarine at night, and basically figured out the setting of the reef and artificial reef by means of surveying and platooning. and planted bombs on a number of key reefs.

A large number of equipment for the landing was manufactured and sent to the United Kingdom. The 21st Attack Aircraft Wing also received a new piece of equipment that they had taken unexpectedly, the Ground Attack Command Vessel.

It is a ship of more than three thousand tons, and its predecessor was a private cruise ship. After the start of the war, its owners donated the ship to the British Royal Navy. During the retreat from Dunkirk, this cruise ship, which had a speed of up to 30 knots, rescued many soldiers. After that, the ship was also converted into a destroyer for anti-submarine use. However, this ship is not suitable for operating in too high sea conditions, and the original civilian ship is difficult to undertake high-intensity anti-submarine combat missions. The maintenance of the ship was ridiculously high, and as a result, the Royal Navy, which had recovered its strength, quickly threw it into reserve.

During the drill to attack the beachhead, the 21st Attack Aircraft Wing did expose a problem in its command, that is, the problem of radio communications. This is how the radio commands received by the attack aircraft of the 21 Attack Aircraft Wing came. First, the guide who stayed on the cruiser gave the signal that the shelling was over, and then the air combat command center gave the command to attack. Taking into account the complex electromagnetic environment on the cruiser, coupled with the fact that the Navy itself has a large number of radio communication tasks, the transmission of attack signals sometimes has a noticeable delay.

And once the soldiers are on the beach, the target guidance is handed over to the walkie-talkies of the guides who stay in the landing force. But walkie-talkies can't be directly connected to fighters, which also requires an intermediary. The cruisers, which were busy with fire support on the opposite shore, could hardly take on this task. Therefore, the 21st Attack Aircraft Wing urgently needed a command center close to the battlefield.

At first, Ron just wanted to find a destroyer among the U.S. warships to use. But later, I don't know who it was, I suddenly remembered the ship of the British. If you think about it, the tonnage of this ship is larger than that of a destroyer, and it does not need to be equipped with weapons, and it has a large space, which is especially suitable for changing into a dedicated command ship. Thus, a completely new class of ships appeared.
