The harder you work, the harder it is to surrender.

Every strike of hammer - hits the enemy!
V. Deni, A. Dolgorukov, 1941

Due to the attack of the Nazi armed forces, which could not be stopped at the moment, a great many of Soviet industrial works and factories had to be evacuated to the east, so that the invader could not make use of it and increase its power, which was already ample due to the capture of French and Polish industry and resources. The task was unbelievable – more than 1500 of works and factories with machinery along with the 10 mln of personnel had to cover thousands of kilometers to the new places where there was no infrastructure at all. And they had to start operation there as soon as possible, as the battle-front was in great need for the arms and munitions. Adults and children were working 12 hours a day without weekends, in order to protect the Motherland.

This incredible efforts paid off well: although in the second half of 1941 gross industry output dropped down 2.1 times, in the beginning of 1942 it started to grow at fast pace, fully eliminating the industry superiority of fascist Germany in 1943.
