Located in the southwest of the city of Berlin, Potsdam is a famous historical and cultural city, although the city is small, there are still well-preserved royal palaces, known as the royal gardens since ancient times. There is also the Sanssouci Palace, which is designed in the style of the French Rococo period, and the historic Nicolas Cathedral. The Nationalist army is surrounded on all sides, and once the battle starts, these ancient buildings may be destroyed at the same time. To this end, Adrian has sent urgent messages to the front line more than once, mainly emphasizing that the siege troops must do four things: first: they must ensure the safety of people's lives and property; 2. Be sure to protect all cultural and ancient buildings in the city; Three: Must capture alive the enemy's 19th Army Major General Commander-in-Chief Kurt? Feng? Schleicher; Fourth, it is necessary to focus on attacking the heart and supplemented by attacking the city, and strive to disintegrate and divide the enemy army; Just these four musts make the front-line soldiers at a loss. What can be done to conquer Potsdam without destroying this ancient cultural city? An important subject before Hoffmann and General Rundstedt.

The wind and snow did not stop, the temperature was low, and the commanders of the various units soon gathered in the chapel south of Potsdam. General Rundstedt first read out Adrian's telegram, then briefly described the characteristics and significance of many ancient buildings in the city, and then asked everyone to work together to make plans to attack the city as scheduled and to meet Adrian's four imperatives.

Potsdam is a small city with nearly 100,000 permanent residents, and now it has suddenly stationed nearly 50,000 people in Schleicher, which has greatly exceeded the limited load of the city. At present, the only feasible way is to first resolutely understand and implement the fourth imperative proposed by Adrian, that is, to break up and divide the enemy army with the attack on the heart as the main and the siege as the supplement. In the light of these circumstances, the armored vehicles and tank units were certainly no longer needed, and the general commander finally decided to surround them with a large corps, and constantly set up a small detachment led by the former commandos to penetrate deeply, and the plan to cooperate with the propaganda regiment was approved. At 19 o'clock in the evening, the first batch of shrewd and capable officers and men were selected from the various group armies, and each group of 12 men was formed into 10 first assault detachments. On the square in front of the small church in the south of the city, General Hoffmann personally marched for them, and the commander of the 501 tank battalion, Erwin ? Major General Rommel and veteran commandos gave offensive and defensive drills to the commandos before the departure in batches, including the understanding and use of various gestures, the issuance and acceptance of simple passwords, and so on.

Such detachments are sent out every 30 minutes, gradually and progressively reinforcements, and each detachment will attack on its own after setting off, fighting its own battles, and the main direction of attack is the square in the center of the city, seizing the commanding heights, controlling the city government building, and capturing Schleicher alive.

Each commando team is assigned two propaganda team members with loudspeakers, who are under the unified command of the commando team leader, and stresses that the special combat personnel must first ensure the safety of the propaganda team members in order to disintegrate and divide the enemy, and they must not use weapons unless absolutely necessary. Felix was the captain and deputy head of the mission, and he and his team member Bauer participated in the operation of the 5th Special Operations Commando led by Lieutenant Company Commander Erwin.

Both the nascent National Army and Albert's government army were unfamiliar with street fighting, especially in difficult battles under complex conditions. The special operations commandos set off quietly from the south of the city, and before 20 o'clock, they had to arrive at the various entrances to the city to cover themselves.

At 20:200 a.m., the loudspeakers and the ragged sound of gunfire could be heard from all entrances to the city, including the sound of recalcitrant G-16 semi-automatic rifles, the gunfire of commando MP16M submachine guns, and the occasional rumbling explosion of grenades. This was something that Hoffmann and General Rundstedt had long anticipated, and the siege would never be so easy, but they still firmly believed that the role of the mission was indispensable, and there must have been a reason why Adrian emphasized the importance of the mission over and over again.

Due to the fact that the recalcitrant army in the city had been deceived by the Albert government for many years, and some officers and soldiers had foolishly pledged their allegiance, the special operations commandos at each entrance to the city were blocked to varying degrees, and some of the commandos fought very hard. Soon after the 7th Special Operations Detachment, which had broken into the city from the east, it was met with frantic resistance from roadblocks and sandbag positions, and two members of the team and one of the preacher were wounded and their advance was blocked.

The other teams have been in this situation to a greater or lesser extent, and the attack speed is very slow.

The Fifth Commando was also very difficult, first infiltrating the city was relatively smooth, but then accidentally triggered the physical alarm device set up by the defenders, it turned out that Schleicher used physical principles to set up such triggers in various entrances to the city and many deep areas in order to prevent the Nationalists from sneaking up at night.

As soon as the alarm device sounded, more than a dozen flashlights were fired at the team members entering the city. In the darkness of the night, when the strong beams of light prevented the team members from opening their eyes, the machine guns hidden in the buildings began to fire wildly, and most of the attacking troops were planted in these places, and they were shot and fell before they could see which direction the enemy was. The alert Captain Erwin dodged and took cover in the narrow alleyway, loudly ordering the other team members not to rush and to find cover on the spot.

The flashlight went out, and the ignition point was dark again, but the shadows of people could be faintly seen on the snow-covered streets. Captain Erwin 'Geihard (henceforth referred to as Gaehard) comforted the wounded and reminded everyone not to risk their lives, and then used the snow's insignificant vision to search the enemy's position, and in the darkness, he could only see a row of black sandbags in front of him, and the recalcitrant soldiers were hiding in the bunkers made of sandbags.

It was time to play the role of a preacher, Captain Erwin pointed across the street to Felix, and put his left hand to his mouth in the shape of a trumpet. Felix immediately understood, quickly took out the megaphone and began to shout to the other party. Taking this opportunity, Gaehard quickly removed the rope he was preparing to climb on, wrapped one end of the rope around a stone and threw it at the injured team.

"Hold on, brother." Gaihard lowered his voice, "Quick, yes, yes, don't let go, okay, good, that's all." ”

"My name is Frank, Captain Gaehard, I'm hurt, but I don't know where the injuries are" said the soldier, who was pulled back to safety, "I tried to stand up, but I didn't do it, I was in pain all over, I might die, right?" ”

"Nope! You're not going to die. Gayhard checked his injuries, "Very lucky, dear Frank, you are much luckier than we are, you only took a few shots in the leg muscles, you see, we still have to fight, and now you can retire from the battlefield with honor." ”

"But I can't move now, and it's still a battlefield, I mean...... Dear Captain Gaehard, I need help very, very much right now. Frank feared he would be left behind.

Gayhard wanted to laugh, but he couldn't laugh "Okay dear Frank, we won't leave you alone, the situation ahead is unknown now, I can only hide you here first, and when the follow-up troops come up, there will be medical personnel to follow up, and they will take you away, okay, that's it, oh, thank you very much for your short cooperation Frank." ”

The preacher's shouting had no positive effect, and was responded to by a few crisp gunshots, which sparked on the walls. Knowing that it was a hard stubble, Gayhard made a fire suppression maneuver to all the team members, using the cover of the submachine gun to roll on the ground against the wall in a row, while throwing several grenades in the direction of the enemy's sandbag bunker. The team members quickly followed, and fired in unison, the rate of fire of the enemy's rifle was not as good as that of the submachine gun, and it was not the opponent of the squad at all, but they did not retreat, and they made substitutions layer by layer, and went forward one after another. Schleicher also considered that the full pressure of the troops would lead to unnecessary casualties, and unexpectedly adopted the same reinforcement method as the Nationalist army.

During the firefight, two members of the team were killed, and Gayhard did not remember their names for a short time, so he had to take off their badges so that they could be handed over to the Death Committee after the battle. The enemy troops on the ground are not terrible, the key is that the machine gun hidden in the upper floor is too threatening, and Frank was also injured by the machine gun. The hidden Heavy must be killed! Gehad made a roundabout gesture to Fred and Edmond, and the two of them understood, smashed the glass of the house on the street with the butt of their rifles, and rolled over and leapt into the ......

It was a small three-story building, and it was very dim inside, and I could barely see the snowy night outside the window. The owner of the building was long gone, and Fred and Edmond searched and advanced in stealth to find a way out of the back in order to get behind the building where the machine guns were set up. The two of them turned around and walked through two sideways alleys to a slightly wider courtyard. With the help of the misty snow, dozens of boxes of ammunition could be seen stored under the corridor, and two figures walked in front of the ammunition boxes, most likely two sentry posts. Fred motioned to Edmund for a close assassination, so the two of them quietly approached under the cover of the night and quickly flashed behind the ammunition box, at which point the two guards turned their backs to them, saying that it was too late and too soon, Fred and Edmond one by one, covering the guard's mouth and nose at the same time, and stabbed the two guards in the chest with lightning speed. There were a few boxes open, and Fred stepped forward and touched them with his hand, confirming that they were rifle bullets, and then motioned to Edmond: There was nothing wrong with the route.

The two were very happy and looked for a way up the stairs together. After turning a few corners, he was about to go upstairs when he suddenly found at least a hundred defenders resting with the light radiating from the explosion of the grenade outside. It was one of more than a thousand temporary garrison barracks in Schleicher.
