As soon as Shulka put down the phone, the Germans launched an attack on the hospital.

The Germans threw in infantry regiments...... Attacking hospitals and schools should be more important to throw in armored regiments, because places like schools and hospitals will always have more open space for tank maneuvers.

The problem was that the German army at this time was fighting on several fronts, especially in the north to block the Stalingrad Front, where almost all of its armored main forces, the Fourth Panzer Army, were used.

In the Stalingrad direction, the only thing the Germans could do was to throw in infantry regiments.

However, this does not mean that the Germans did not have tanks, and German infantry regiments also had tanks, but in smaller numbers.

The Germans did not come up much, only one company, and two tanks covered the attack on Building No. 5 in the northwest corner...... In order to facilitate the identification of operations within the troops, Shulka had numbered the buildings before that.

In fact, the hospital and school buildings were originally numbered, but the numbering of the two buildings would be duplicated and not conducive to command, so they were renumbered according to the direction.

Shulka raised his binoculars and looked in the direction of the German attack, seeing only a shadow of tanks and a few infantry movements.

The German offensive did not look very good, but it was actually smart.

Building 5 was the more marginal of the hospital, with only Building 17 on the other side providing cover, and the Germans attacked from the flank of Building 5, so that they did not have to face the firepower points in the building that relied on walkways, doors and windows.

All the Germans had to do was to punch a hole in the side wall with a tank, and then the Germans could rush in and grab control of the building with the Soviets at close range.

As long as Building 5 is captured, it can be used to cover the rest of the German army to continue the attack, that is, to break through individually.

This is also a weakness of relying on building defenses.

Buildings are not like a line of defense, which can be reinforced with trenches, communication trenches, or provide fire support from a distance.

However, the defense inside the building is that on the one hand, the open space between the two is often blocked by enemy machine gun and artillery fire, and on the other hand, there are many blind spots between each other.

As long as the enemy finds the right angle to attack, the Soviet troops in other buildings can only watch and cannot participate.

This was much the case, with most attacking Germans either in the blind spot or out of range.

However, the Germans were wrong if they thought that the defense of the Soviet army would be so simple.

"Number thirteen, secret position 1672, distance 281, three rapid fire!"

"Number fifteen, secret position 1928, distance 309, three rapid fire!"

……

With a series of orders, the mortars on the roofs of each building let out a roar, and a single shell accurately smashed into the German offensive position and exploded.

The advantage of building defense warfare is that the distance between buildings is constant, and they will not move without feet, so artillery observers can map them on the spot early in the morning and record the data on the drawings.

As soon as the Germans launched an attack on a certain point, the artillery observer could easily mark the enemy's position on the drawings and calculate the mortar positions that could hit the enemy and even provide them with accurate elements.

In this regard, Shulka did not dare to hope that every soldier of the 82nd Infantry Regiment would learn to calculate the dollars.

In fact, there is not much need for this, and at the same time, the general level of education of the Soviet infantry is low, and it will not be able to learn in a short time.

So Shulka selected more than 30 people from the army as artillery observers to train ...... It was not difficult to select thirty or so people from more than a thousand soldiers, who either had a certain level of education or were originally artillerymen.

What they have to do is practice ballistics calculations and measurements all day long, combined with mortar training.

With these people, the rest is simple.

The first thing to do after the occupation of the hospital was to pull a few telephone lines in the various buildings...... This was supposed to be done by radio, but of course the 82nd Infantry Regiment would not have any radios, and would have to be replaced by telephone lines.

The reason why I had to pull a few phone lines was because I was worried that the phone lines would be blown up and I would lose contact.

Of course, in addition to this, the communication corps must also be ready to be wired at any time.

As a result, the entire complex is united into a single unit through these telephone lines to support each other...... After calculating the data, the observer told the artillerymen that the artillerymen only needed to shoot the shells out according to the order.

The Germans did not give up on this, they continued to charge despite artillery fire, and even had already blown a large hole in the side wall with a tank gun.

It looked as if victory was already in sight, as they only had to burrow into the wall to dodge the mortar shells whizzing overhead.

However, they are still naïve to think so.

Moving on, suddenly a volley of grenades fell from the sky, followed by another row...... The grenade exploded like a firecracker near the hole in the wall.

And the German tanks were helpless about it...... Tank guns have a certain angle of elevation, and if the distance is too close and the target is at a high level, it will exceed its elevation angle and cannot be fired.

And that's not the worst of all, as a torrent of bullets rained down and the German soldiers screamed.

It turned out that the Soviets had already carved holes in the side of the wall, and in order to confuse the enemy, they also plugged the holes...... If the holes were too obvious, the Germans would knock them out one by one with tanks or assault guns beforehand.

Then, when the Germans approached, the firing holes were suddenly opened to shoot at the enemy.

Under these conditions, the Germans were almost powerless to fight back, leaving a body in the desert and fleeing amid the sound of gunfire and explosions.

In the end, there was even a tank that was hit by a rocket when it turned around, and it caught fire.

The next time the Germans attacked, they learned to behave.

They first bombarded the sides of the wall with tank and artillery fire, and the side walls were all in ruins and even collapsed in some parts, so that there was nothing left to be a cover for the Soviet troops.

At the same time, the Germans also organized more intense mortars to suppress the roofs of the buildings, and in this case launched another onslaught under the cover of tanks.

This time, they managed to break into the first floor of the building.

The German soldiers were about to breathe a sigh of relief, only to suddenly find that they had fallen into another trap.

Not a trap, exactly, but a minefield.

The entire ground floor was already full of mines, underground, in the tables, by the windows......

"They actually planted mines in the house!" Major General Andreas, commander of the 29th Motorized Infantry Division, shouted angrily: "How can they lay mines in the house? Who would bury a mine in a house? ”

If Shulka hears this, he asks rhetorically: "Why can't you plant mines in your house?" As long as it works! ”
