I am mainly interested in military sabotage. But there was also economic and technical. Why, with minor losses, Germany suffered a shortage of manpower throughout the war. Hitler did not want to push the replenishment to the front and in every possible way prevented this.
In his victory, Hitler was confident in the same way as Stalin in his defeat. In the fall of 1941, the German government decided to curtail its military industry. On October 3, 1941, Hitler said: "We have ensured everything in advance, that I am in the midst of the battle I can stop further production of weapons in major industries, because I know that now there is no enemy that we could not crush with the existing stock of weapons ".
The human reserves of Germany by September 1941 were not yet substantially affected by serious mobilization, although by June 1941 the number of German soldiers reached 7,254,000 people. On the first day of the war, the Soviet government issued an order to mobilize persons liable for military service who were born in 1905-18, after the attack on the USSR, the German army did not produce any additional mobilizations.
Nothing has changed after the defeat at Moscow, except for the January order of Hitler in 1942 on the redistribution of budget allocations within the military department. The cost of the most expensive type of armaments — warships — was reduced and the costs of arming ground forces increased.
Only after the defeat at Stalingrad did Hitler begin to approach the war with the USSR more seriously. On January 13, 1943, the so-called total mobilization was announced in Germany. But it was not in the mobilization, as such, but in the registration for military purposes of men aged 16 to 65 years and women aged 17 to 45 years. Nevertheless, despite the serious situation on the fronts of Germany, female labor in German industry was practically not used until 1944, as well as children’s work, since it was thought to disintegrate the family and badly affect the morale of men in the army. Female and child labor in Germany was partially compensated by the labor of foreign workers and prisoners of war, which by the spring of 1943 numbered 6,259,900 people in German industry. Thus, if the Soviet industry from the first to the last day of the war worked for wear and all healthy men were mobilized into the army, and unhealthy, teenagers and old men into the militia, Germany only in 1943-44, under the influence of the defeat at Stalingrad and the Allied bombings German cities began to take war seriously.
The German military industry reached its highest performance in the days when the Allied bombing took the greatest scope - in July 1944. Then, in the second half of 1944, the number of the German army, despite numerous losses on the fronts, was, in general, easily brought to 9,400,000 people.
After the summer of 1944, due to the bombing and loss of territories, there was a decline in the German military industry. And yet, in March 1945, Germany produced more weapons than in June 1941, when Hitler launched a war against the USSR.
