The initial attempts at evacuation while the war was still in its early stages through early 1942 were a far cry from the organised affair that the Soviet central bureaucracy envisaged. Throughout the summer and fall of 1941, numerous Soviet frontier cities evacuated in a haphazard and panicked fashion before the German onslaught. A number of factors led to this lack of organisation. For one, the Soviet evacuation plans were thrown together fairly hurriedly, and a lot of the logistical planning was done on the fly as the German advance was already sweeping through the Soviet border zone. The German invasion also hampered the effectiveness of the Soviet response by shattering their communications in the war's early stages; many Soviet leaders were unable to gather reliable information about the positions of German forces until it was too late to effect an orderly evacuation.
