Dense gunfire rang out, and the German soldiers behind each tank were very consciously divided into two pulls, one pulled out and retracted immediately after firing a shuttle of bullets, and the other pulled out and continued to shoot.

This tactic, combined with the rate of fire and penetration of the MP43, caused the charging Soviet troops to fall in front of the tank ranks...... This is also the reason why there is basically no group charge in modern warfare, and the firepower that two automatic rifles can provide is basically equal to or even greater than that of a light machine gun, so this is equivalent to countless light machine guns shooting at the charging Soviet troops, and the density of this bullet is enough to keep the Soviet troops out of a safe distance, especially the German soldiers will throw a few grenades outward from time to time.

(Note: The theoretical rate of fire of automatic rifles is similar to that of LMG guns, which is about 600 rounds per minute, and the actual rate of fire of LMG is faster because of the larger ammunition capacity)

Finally, after dropping a large number of corpses, the Soviet charge collapsed.

There is still a big difference between theory and practice...... Theoretically, none of these Soviet soldiers could retreat, not a single step. But at the moment when they really charge on the battlefield, when the dense bullets fly past their ears, or when the comrades in front of them are knocked down like mowing grass, the fear in their hearts still cannot be overcome.

They were all about fleeing back to the trenches in panic and screaming.

But escaping back to the trenches did nothing.

The paving tank continued to move forward slowly, laying steel plates on the road piece by piece as it moved, although the road was already full of Soviet soldiers' corpses, and the next second the tracks were heavily rolled up...... The blood immediately burst out like a balloon that had been burst, and with a crisp sound of bones being crushed like dry wood breaking, the ground around it was immediately bright red.

Qin Chuan couldn't help but flash the picture of squeezing watermelon juice in his mind, but what wafted on the tip of his nose was not the fragrance of watermelon juice, but a strong smell of blood, and what was left around was not discarded melon skin, but the arms, thighs, and head that were straight and broken at various angles, and the most terrifying thing was the remnants of the upper body, because the lower half of his body was crushed, and the squeezed blood seeped out from the eyes, nose, ears, etc., and the veritable seven orifices bleed, which was extremely terrifying like a ghost.

But the German soldiers did not relent, they prepared grenades as they followed the tanks, and then with a sharp whistle, they leaned out and threw grenades into the Soviet trenches under the cover of several riflemen.

Just heard a burst of "boom", and a puff of smoke exploded in the Soviet trench, and then the soldiers rushed up with MP43, and there was another burst of gunfire, and the trench was emptied in a short time.

The tank easily crossed the trench and continued to advance forward, with the infantry following closely behind...... They could not be considered to have broken through the Soviet defenses, because after this trench there were second and third trenches.

However, it was obvious that the Soviet forces were mainly concentrated in the first line of defense, and the second and third lines of defense could not withstand the impact of the 21st Panzer Division without preparation, so the Germans quickly drove the road behind the Soviet line and advanced north along the Don River.

Hearing the news that the defensive line had been breached, the most alarmed was not the 64th Army, but the 62nd Army.

The reason was that the 62nd Army was the shore defense force responsible for guarding the defense line of the Don River, and all its troops were engaged along the Don River to confront the German 6th Army across the river, when a German unit suddenly appeared on the flank...... This was almost the encirclement of the 62nd Army from the rear.

Lieutenant General Lopatin immediately reported this information to the commander of the Front, Colonel-General Yelomenko.

"Comrade Yeyumenko!" Lieutenant General Lopatin reported in alarm: "The Germans broke through the line of the 64th Army, and the flanks and rear of the Don line were seriously threatened!" ”

"I know, Comrade Lopatin!" Yeomenko replied: "We are trying to drive this group of Germans back, hold your line and keep calm!" ”

"Yes, Comrade Yeyumenko!" After Lieutenant General Lopatin hung up the phone, he couldn't help but feel a little calmer, because he listened to the words of General Yeliaomenko and thought that the front army had enough strength to plug this gap.

Admiral Ye Yaomenko did think so, but in fact, Ye Yaomenko was deceived by Qin Chuan again.

The German 21st Panzer Division had two options after breaking through the Soviet 64th Army:

One was to advance eastward, go around to the rear of the Soviet 64th Army, and completely crush it.

The other was to advance northward, go around the rear of the Soviet 62nd Army, and cooperate with the German 6th Panzer Army to land.

Originally, Admiral Yesyanko thought that the Germans would choose the former, because the Germans launched a fierce attack on the defense line of the 64th Army, while the Sixth Army in the direction of the Don River did not move at all...... Of course, the 64th Army is also the option that Yeliaomenko must save, because once the 64th Army is destroyed, then the south of Stalingrad will be directly exposed to the German artillery, and at this time Stalingrad's preparations are not perfect and the supply of troops is not sufficient.

On the other hand, through reconnaissance on the front line, Yelmenko also got that the Germans moved to the northeast as soon as they broke through the defense line, implying a posture of encircling the 64th Army, so General Yelmomenko did not think much about it and immediately sent reinforcements to the 64th Army...... This is also the reason why Yelmomenko did not react to the report of Lieutenant General Lopatin, who assumed that the focus of the German offensive was the 64th Army.

This is easy to understand, after all, the German troops who broke through the line were under the command of Hort's 4th Panzer Army, and their best target should also be the frontal enemy of the 4th Panzer Army and not the Don Line.

But soon Yelemenko found himself fooled by the Germans, because an hour later, the Germans suddenly turned their spearhead and marched north at full speed into the rear of the 62nd Army, and at the same time there was a fierce artillery fire from the Don defense line...... The battle of the German 6th Army to force the crossing of the Don River began at this time.

Throughout the whole beginning, the Soviet army not only failed tactically, but was also repeatedly deceived and fooled by the Germans strategically, and it is a miracle that this battle can be fought well.

When Yesyanko found out about this, he immediately ordered Lieutenant General Lopatin to transfer the tank units to the flanks.

But it was already too late.

In the process of mobilization, the Soviet tanks were bombed by German bombers in waves, and nearly half of the more than 80 tanks of the entire tank brigade were lost.

Then they met the 21st Panzer Division halfway through, and were beaten by the 21st Panzer Division's artillery and bazookas, and almost all of them were wiped out, and only three light tanks fled back to Stalingrad with wounds.

And the 21st Panzer Division once again rushed at full speed towards the Soviet port of Karachi.
