The decisive influence on the shaping of the organization and tactics of the German infantry before the outbreak of World War II was, on the one hand, the experience of the previous World War, but also theoretical works created in the 1920s and 1930s, which often emphasized the need to perceive the German infantry as a tool waging an offensive war. This affected both the equipment and the organization of the German infantry division, which during the September campaign of 1939 consisted of 3 infantry regiments, each of which was divided into 3 infantry battalions, an artillery company and an anti-tank company. In addition, there were numerous support units, including: an artillery regiment with 4 artillery squadrons (including one heavy), an anti-tank battalion, a sapper battalion and a communications battalion. In total, the so-called infantry division In the first mobilization wave, there were approximately 17,700 people and had a significant artillery component, but also was abundantly equipped with machine guns. It also had modern and efficient - for those times - means of communication and command. In the course of the war, infantry divisions underwent transformation - in 1943 some of them were transformed into armored grenadier divisions. However, from 1943, the standard division of the "traditional" infantry consisted of approx. 12,500 men (and not approx. 17,700 as in 1939), and its artillery component - especially heavy artillery - was also reduced in it, while its anti-tank defense was significantly improved. It is assumed that during the entire Second World War, about 350 infantry divisions served in the Wehrmacht.
Battle for Kharkiv was played from February 21 to March 18, 1943. It is assumed that about 70,000 soldiers took part in the battle on the German side, while on the Soviet side - about 340,000. soldiers. On the German side was commanded by Field Marshal Erich von Manstein, while on the Soviet side - Marshal Filip Golikow. The genesis of the Battle of Kharkiv in 1943 dates back to the German defeat at Stalingrad in February 1943 and the Red Army's move to the west offensive in the area of today's south-west Russia, which was aimed at the German Army Group "South". At the beginning of February 1943, Soviet troops liberated, among others, Kharkiv, Kursk and Belgorod. At the same time, however, despite the successes, the Soviet troops were stretched significantly, their logistics was defective and, above all, they suffered relatively high losses in the course of their offensive operations. In this situation, despite the significant numerical superiority of the enemy, the German troops (especially armored forces - including the 2nd SS Panzer Corps) launched the offensive and in the period from February 21 to 28, 1943, they encircled and destroyed the Red Army troops fighting south of Kharkiv. On March 4, the II Corps entered the city, retaking it from the Soviet hands until March 15, and three days later Belgorod was recaptured. The Battle of Kharkiv stabilized the eastern front until the Battle of the Kursk in July 1943. In the course of the fighting, the Soviets lost about 80,000 people, while the German side - about 11,000 people.
