The German 2nd Army, one of the main infantry armies of the German Army. Although, the 8th Panzer Army and the 9th Panzer Army became the two most powerful armies in the German Army. However, the other infantry armies were also motorized. The 11 divisions under its jurisdiction basically include one armored division, two mechanized infantry divisions and eight motorized infantry divisions, and also have a large number of armored units.

This also made the main infantry armies of the German army have extremely strong attack power in the war. This time, to cut off the retreat of the Russian Southern Front, General Braucić directly ordered his 2nd Army to undertake this task. This task is not an easy task. Once the Russian army finds that its rear road has been cut off, it will inevitably do its best to launch a counterattack in an attempt to open up a retreat. At the same time, there is also the possibility of being flanked by reinforcements from the Russian army.

As the commander of Army Group D, General Brauchitsch naturally let his 2nd Army take on this important task. Although it was a little more dangerous, he believed that the 2nd Army would be able to accomplish this task. At that time, the battle merits obtained will be the greatest.

On September 20, the general offensive of the German Army Group D on the Russian Southern Front began. The German 2nd Army took the lead in the attack. The 2nd Panzer Division, the 21st Mechanized Infantry Division, and the 22nd Mechanized Infantry Division took the lead and launched an attack from the right flank of the Russian Southern Front. More than 500 tanks, divided into three routes, stormed the defense line of the Russian 9th Army.

The 9th Army of the Russian Army, with strong troops, has the 14th Army, the 35th Army, the 48th Army, the 2nd Cavalry Army, the 2nd Mechanized Army and the 18th Army. Among the several group armies of the Southern Front, it was undoubtedly the most powerful group army.

The commander of the army group, Lieutenant General Cherevchenko, ordered the 2nd and 18th Mechanized Corps to meet the German 2nd Panzer Division, the 21st Mechanized Infantry Division and the 22nd Mechanized Infantry Division, while the other three infantry corps were to hold the defensive line to the death, and the 2nd Cavalry Corps was cruising around the perimeter, ready to launch a deadly attack on the Germans.

At the same time, Lieutenant General Cherevchenko did not forget to report the situation here to Marshal Budyonny and asked for reinforcements.

It's just that the current Marshal Budyonny simply doesn't have many troops to reinforce him. The Russian 12th and 18th armies, as well as the 9th independent infantry army, are under siege by the German 19th and 20th armies, as well as the 1st, 2nd and 3rd Ukrainian armies.

A fierce battle ensued. In order to keep the back road of their retreat, the Russian 9th Army was very brave. Two mechanized infantry corps engaged in fierce battles with German armored units in the area of Kujiinikové.

Although, the mechanized units of the Russian army are also equipped with quite a few tanks and armored vehicles. However, the numbers were far from being comparable to the German army. The performance of the tank is much worse than that of the German Haw Par tank. As a result, the two mechanized infantry corps of the Russian army, although they were brave, were defeated by the Germans for every result.

After a morning of fierce fighting, the German 2nd Panzer Division, the 21st Mechanized Infantry Division and the 22nd Mechanized Infantry Division surrounded and annihilated the Russian 2nd Mechanized Army and inflicted heavy losses on the Russian 18th Army. Other units of the 9th Army of the Russian army had to retreat. Lieutenant General Cherevchenko, who ordered the 2nd Cavalry Corps to break off, bought time for the retreat of the main forces.

In the German Army, there were no formed cavalry units, only some border troops, and a small number of cavalry were equipped. There were also some ceremonial troops, which kept a little cavalry. But, basically, on the battlefield, the cavalry was no longer visible. The role of cavalry has been replaced more by armored and mechanized units.

The Russian army is relatively backward in terms of development in terms of armored forces and mechanized forces. In order to improve the mobility and shock ability of the troops, a lot of cavalry was still retained. Especially in the civil war when the country was just founded, cavalry played a vital role in the war, so Burussia still attached great importance to cavalry. This is inseparable from the fact that several giants of the Russian army are from cavalry, for example, Marshal Voroshilov and Marshal Budyonny are both from cavalry generals.

In the face of the Russian cavalry, the German 2nd Panzer Division launched a direct attack. The sabers of the Russian cavalry were equipped, although they were sharp. However, in the face of tanks and armored vehicles of the German 2nd Panzer Division, nothing could be done. No matter how sharp their sabers were, they couldn't destroy them. On the contrary, the German tank guns and machine guns could shoot them indiscriminately.

The Russian 2nd Cavalry Corps, under the attack of the German 2nd Panzer Division, only held out for an hour before collapsing. A large number of cavalry, turning the horse's head, retreated frantically. At this time, the cavalry's rapid mobility was brought into full play. At the very least, it is much faster to run away on a war horse than for the infantry to flee on two legs.

"Your Excellency, the Russian 9th Army has been routed, and we are pursuing the enemy. It is expected that by tomorrow the retreat of the Russian Southern Front will be completely blocked! A staff officer reported to Admiral Brauchitsch.

Admiral Braucić nodded with satisfaction, and after cutting off the retreat of the Russian Southern Front, these hundreds of thousands of Russian troops became turtles in the urn. Next, they will be able to easily deal with these Russian troops.

"Send a telegram to several other army groups and ask them to intensify their attacks. Be sure to solve the Southern Front of the Russian Army in the shortest possible time! Admiral Brauchitsch ordered.

"Yes, General."

As the Russian 9th Army was routed by the Germans, two mechanized infantry corps were lost, which dealt a fatal blow to the Russian Southern Front. The other two armies of the Southern Front of the Russian Army, under the blows of the superior forces of the German and Ukrainian armies, were already losing and retreating one after another, unable to defend. The rout of the 9th Army became the last straw that broke the camel's back.

When Marshal Budyonny learned of the defeat of the 9th Army, his face was filled with despair. You know, even in the Russian Civil War, he has never been so desperate in the face of an enemy several times his size. But now, he really despaired. Because, he felt as if he had lost any hope.

On September 21, the German 2nd Panzer Division continued to advance southward, cutting off all the retreats of the Russian Southern Front. Other units of the German 2nd Army formed a defensive line in the eastern part of the Russian Southern Front to prevent the retreat of the Russian Southern Front to the territory of Burussia.
