The Second World War is still of great interest for researchers in different areas. Economic international relations, military operations from the battle period of time have not been deeply investigated so far. There are a few reasons for that.

Others were kept in secret from the public, for they still represent pages of tragic memories, caused by mistakes in planning and implementation process. The article under consideration describes some events that have not been covered so far in historiography.
