On May 12, the Soviet Red Army launched an offensive towards Kharkov.

Fafnier's Tiger No. 223 was initially on the front line to fend off the Soviet attack. "2 o'clock, T34, distance 800, armor-piercing shells!" Now he was seated in his captain's seat, giving orders unhurriedly: forward, shoot, backward, shoot.......... completely like a successful man, with no sense of urgency at all—this is fake! In fact, he was sweating and shouting hoarsely to order the crew to fight. The tanks of the Russians, as always, poured in like a tidal wave, and the German defense line was struggling to support it.

It didn't take much time, and on the night of the 12th, the order was given: Fafnir's No. 223 and the other Tigers were withdrawn and transferred to the southern front to assemble and stand by.

The Soviets advanced rapidly after the Germans had removed their armoured units, advancing to Zaporizhzhia in just a week, and capturing the city after two days of fierce fighting.

On 22 May, the Russians were still advancing, their morale was high but their personnel were exhausted, and the losses of tanks and self-propelled guns along the way were heavy, and the capture of the front headquarters of the German Army Group South made the Red Army commanders and fighters at all levels very optimistic that they would soon reach the Dnieper. But by this time, the armored spearhead of the German army was about to launch a pincer offensive against the exposed and vulnerable flanks of the Red Army......

Fafnier's Tiger 223 waited quietly in the south for assault orders, next to Eckert, who was now in tank destroyer No. 4 and was once again assigned to Fafnier's assault group after almost a year of absence. The old colleagues were naturally very happy to meet, glad that their own family had not died on the battlefield.......... the low-pitched No. 4 would follow the tiger to attack and provide long-distance support firepower for the tiger.

In the early morning of the 23rd, the German counter-assault began. Without any prior fire preparations, the Tiger tank took the lead, and the Panthers and the No. 4 tank and assault guns followed, taking the Soviet Red Army by surprise. The attack went very well, and the first line of attack was not the second company of the 503rd Battalion of Fafnier, but the Waffen-SS Tiger tank unit, and Eckert despised these murderers as always, but he still provided fire support for them out of his duty as a soldier. Fafnier's No. 223 was not on the first line, he stayed in the second line and was ready to strike in waves.

On the 23rd, the absolute superiority of the German tanks in terms of quality, combined with proper tactics, gave the German army a one-sided victory. Their powerful armored wedges soon opened a large gap of more than 30 kilometers in the positions of the 6th Army of the Red Army, along which the German SS "Reich" division, which had routed the 4th Army of the Red Army, advanced more than 100 kilometers south at an alarming high speed. On 24 May, two other armies, the 48th and 57th Panzer Corps, which belonged to the German 4th Panzer Army, also launched an attack. The German army soon joined up with the SS Panzer Corps in the Pavlograd area and cut off the lines of communication of the Red Army's 6th Army. Immediately afterwards, the German 40th Panzer Army, with three armored and armored infantry divisions, delivered a fatal blow to the Popov cluster of the Red Army, which had run out of fuel.

But later on the 24th, while Fafnir's Tiger 223 was replenishing ammunition and fuel, Eckert, who was ahead of the attack, was lifted down from the front: he was shot in the chest by a Russian sniper, who was shot in the lungs by a hidden Soviet sniper as he showed his head to direct the vehicle to enter, and the Soviet soldier was immediately killed by an artillery hit. Eckert was seriously wounded and was admitted to a field hospital in the rear. Fafnier did not have time to visit his colleagues, and the order for his car No. 223 sortie had already been given.

"This world is really a harsh documentary world...... It's a pity that the other worlds on the other side are too dangerous - who would dare to go to Doraemon's world? Even Hongjun will be played to death..... otherwise it would be too easy to save these guys who can say it. Alas, each has a destiny. Fafnier thought as he commanded the drive.

"Stop! At 4 o'clock! There are so few Russian tanks?! They have finally exhausted their character! Comrade gunner, fire at will......" said Fafnier.

The tanks of the Soviet Red Army were lying on their stomachs due to logistical pressures, and a large number of tanks were unable to fight because they did not have fuel and ammunition. However, the Red Army soldiers fought bravely - they concentrated their ammunition in the best tanks, which could be used as fixed fire points even if they could not be activated, at least the turrets could be fired by hand......... But everything was useless, the Tiger and the Leopard, the No. 4 tank, ignored the Soviet fire from a long distance, and slowly and accurately aimed to send a group of Russian tanks that served as fixed firing points into the sky.

"There's no need to get any closer, just shoot these fixed targets here. Fafnir gave the order in a bored manner, and at the same time machine-gunned the Soviet soldiers who tried to melee them.

After a fierce battle, the Germans claimed that in a counterattack against the Red Army's Southwestern Front, the Germans had routed 8 corps, 10 infantry divisions and 5 special brigades within the 6th, 1st Guards and Popov Fronts, and that 23,000 Soviet troops were reportedly killed. On the other hand, because the German forces that launched the attack did not constitute an absolute superiority, they were not able to form a tight encirclement, and because the weather was cold, the German movement was mostly limited to the villages, so only about 9,000 Red Army soldiers were captured.

Having suffered such heavy losses, the Southwestern Front of the Red Army, under the strong pressure of the German troops rushing in from three directions, had to quickly retreat back from February 27. By June 3, they had retreated across the Severodonets River, where the thin ice had formed to facilitate the passage of the Red Army. But as a result, the Voronezh Front of the Red Army, which was fighting in the Kharkov area, was under the flank threat of the German armored forces.

Initially, not enough attention was paid to the combat operations of the sudden German attack on the South-Western Front, either by the High Command of the Red Army, which was far away in Moscow, and by the Voronezh Front, which was operating on the flank of the South-Western Front. They still stubbornly believed that the German counterattack was nothing more than a cover for their retreat from the Dnieper. Thus, during this period, the Voronezh Front was still desperately advancing westward.

It was only after the Southwestern Front was driven across the Severodonets River by the Germans that the commander of the Voronezh Front, Colonel-General Golikov, found himself in a very dangerous situation: at this time, the German 4th Panzer Army, which had just broken the Southwestern Front, was heading north, preparing to strike at its own troops together with the German "Kempf" battle group. As a result, 3 armies on the left flank of the Voronezh Front (3rd Tank Army, 40th and 69th Armies) would be attacked by 14 elite German divisions (including 4 Panzer Divisions, 3 SS Panzer Infantry Divisions, 1 Motorized Infantry Division, 3 Infantry Divisions). And the Red Army was able to use only about 70 tanks in this direction, and the Germans were no less than 350.

Faced with such a terrible situation, Admiral Golikov hurriedly ordered the Voronezh Front on June 3 to stop all offensive and go on the defensive along the entire front. The Red Army general also urgently asked his superiors to replenish his troops, which were severely depleted, but since the nearest supply base was also 200 kilometers away, reinforcements were completely impossible.

Fafnier met two more old friends, Dick, who had completed the assault on the northern front to join him." Clown". Karl triumphantly brags about the Circle of Death he has just brushed - he has destroyed 14 more tanks, raising his record to 60, and looks likely to get his hands on the Knight's Cross. But now, Carl can only look at Fafnier's knight's cross and drool.......... Juncker is now also a shotgun, he is now the commander of the Panther D tank, and he has achieved fifteen victories for himself, and he is drooling at the knight's cross like Carl, but Juncker has to fight for the first iron cross first.......
