The reasons for the Soviet victory in the Battle of Kursk (all aspects)?

Every day at the beginning of the battle when it was thought that the German army might launch an attack passed safely. The front line seemed very calm for two months. On the night of July 4th, the Soviet Guards in the southern part of the salient The 6th Army captured a soldier of the German 168th Infantry Division. He confessed that the Germans were about to launch an offensive the next day. In the early morning of July 5, the Soviet 13th Army captured a soldier of the German 6th Infantry Division in the northern part of the salient. Sergeant, he also admitted that the Germans would attack in a few hours. In order to disrupt the German offensive, the Soviet army took the lead in shelling the German positions in the early morning of the 5th, and the Battle of Kursk began. German offensive on the southern front: The Soviet artillery bombardment completely caught the German army by surprise and caused great losses, although it was delayed by 3 hours than originally planned. However, the 4th Armored Army of the German Army Group South still launched the attack step by step. After losing 36 tanks, the German army struggled to cross the Soviet anti-tank minefield and stormed the defense line of the Soviet 67th Guards Infantry Division. Facing the attack of three German divisions, the Soviet 67th Guards Infantry Division was unable to block it. Forced to retreat, Vatutin mobilized the front army's reserves in the hope of blocking the German army from the second line of defense. But unfortunately, the German army still opened a gap in the Soviet second line of defense on the 6th and forcibly crossed the Pena River. Because the German attack was much more violent than expected, Vatutin was forced to cancel the counterattack originally planned for July 6, and some of the tanks of the 1st Tank Army planned for the counterattack were deployed behind the defense line to support the infantry. To defend, some tanks were deployed on the flanks to attack the Germans. On this day, the German Air Force conducted more than 1,000 sorties, completely suppressing the Soviet Air Force. After a day of fierce fighting, both sides suffered heavy losses. On the evening of the 6th, Vatutin asked Vasilevsky for reinforcements. After obtaining the consent of the Supreme Command, the latter immediately transferred 353 tanks of the 2nd and 10th Tank Corps of the 5th Guards Group Army of the Steppe Front to Voronezh Front. At the same time, Vatutin received a call from Stalin himself, asking him to prevent the German breakthrough in the southern part of the Kursk salient at all costs. In the 7th day of fighting, the German army only advanced a few kilometers and failed to achieve the task of breaking through the Soviet defense line. The next day, the Germans still tenaciously continued their offensive, and Vatutin was also planning a counterattack. For this reason, he requested the High Command to transfer the 5th Guards Tank Army and the 5th Guards Army of the Steppe Front to his command. , his request was quickly granted, but it took several days for the troops to arrive. In the battle for air supremacy, through two days of air battles on July 7 and 8, the Soviet Air Force gradually reversed its disadvantage. It was only a matter of time before it completely seized air supremacy. July 9th was a critical day in the Battle of Kursk. Vatutin commanded the troops to continue to resist the German advance towards Oboyan from the front, and at the same time launched continuous counterattacks on both wings. Although these counterattacks failed time and time again, they made the German army Unable to attack their main target with all their might. General Hoss, commander of the German 4th Panzer Army, saw that he could not break through Oboyan from the front, so he decided to break through from the right wing first. He ordered the 2nd SS Panzer Army to turn to Prokhorovka in the northeast. In the next two days, the German offensive went relatively smoothly. They captured the city of Prokhorovka, and the climax of the Battle of Kursk - the Prokhorovka Tank Battle - took place. For a long time after the war, historians have always believed that on July 12, 1943, the Soviet Union and Germany had a fierce battle between more than 1,500 tanks and self-propelled artillery in Prokhorovka, and the Prokhorovka Tank Battle was therefore called It is considered to be the largest tank battle in the history of human warfare, and it is famous all over the world and has become a legend. With the passage of time, the declassification of a large amount of data, especially the end of the Cold War and the disclosure of data from the former Soviet Union, allowed researchers to discover that the scale of this tank war was much smaller than originally thought. The tanks and self-propelled vehicles that both sides directly participated in the war There are only about 600 artillery pieces. Among them, there are less than 200 German vehicles and about 400 Soviet vehicles. On the morning of July 12, the battle started. The Soviet Union and Germany launched their attacks almost at the same time. At the beginning, the 88mm gun of the German "Tiger" tank had a clear advantage, while the 76mm gun of the Soviet T-34 tank had a clear advantage at the same distance. Unable to pose a threat to the German army, the Soviet tanks rushed towards the German army at full speed and at top speed. I hope to get close to the German tanks and take advantage of the T-34's mobility to defeat the bulky "Tiger" tanks. During the charge, the Soviet tanks paid a heavy price. As the two sides approached, the battle became more fierce. The tanks were destroyed one by one, but next to the destroyed tanks, the tank crews of both sides were still shooting at each other and even fighting hand-to-hand with each other. The fighting continued into the evening, finally stopping due to exhaustion on both sides, and the battlefield was littered with tank wreckage and corpses.
