In preparation for a military confrontation with Nazi Germany, the Soviet leadership made defense plans based on the fact that the priority target for the enemy would be Ukraine. Immediately before the start of hostilities, unprecedented efforts were made to increase the level of combat effectiveness of military units stationed on the borders of our country, and powerful defensive structures were created. However, due to a number of reasons, all these measures did not have the desired effect. What was the reason for the failures of the Red Army at the initial stage of the war in Ukraine? How did the Wehrmacht manage to achieve such rapid and complete success in a non-main direction of attack? Were any conclusions drawn from what happened? The reader can find the answer to these and other questions in the book by V.A. Runova “1941. A blow to Ukraine.” The book is published in the author’s edition. The publishing layout of the book is saved in PDF A4 format.
