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.
The Battle of Stalingrad is widely regarded as the bloodiest single battle World War II. It was fought between the Red Army and the Axis forces - especially the Wehrmacht - on the Eastern Front from August 1942 to February 1943. It happened as a result of the implementation by the Wehrmacht of a plan code-named Fall Blau, which was aimed at taking over the southern areas of the USSR, reaching the Caucasus and seizing oil fields in Maykop and Baku. However, in the course of the implementation of this plan, as a result of, inter alia, the intervention of Adolf Hitler, the seizure of the city of Stalingrad became one of the main objectives of the operation. For Nazi Germany, this decision turned out to be one of the worst in the history of World War II. The Stalingrad battle turned into horribly bloody and very heavy city fights, during which every house or street was fought, and the front line often ran through rooms or staircases in apartment blocks! Ultimately, as a result of it, the Wehrmacht suffered a great defeat, and the entire 6th Army was taken prisoner by the Soviets, including Field Marshal Friedrich Paulus. It is estimated that during the entire Battle of Stalingrad, the Axis forces lost about 850,000 soldiers - killed, wounded and captured. The Battle of Stalingrad also marked a turn in the war on the Eastern Front, which from then on began to take a favorable turn for the USSR.
