Stalin was gripped by paranoia, and he was merciless to his enemies real and imagined. Advancement in the Communist Party was made by accusations of disloyalty or anti-Stalinist thinking. Three million people were sent to Siberia between 1926 and 1939. The Soviet secret police, the NKVD, would send anyone to the Gulag for a frivolous infraction. Its leader, Levi Beria, was a sadistic rapist who condemned men to death simply to sleep with their wives. Russians called his rule the “Great Terror.”
In 1937, Stalin’s attention turned to the Red Army. Within a few months, most of the Officers from major on up were executed or sent to Siberia. Stalin had cut off the head of his own dragon just as he needed it most. Some 20,000 officers were killed, and fear gripped the survivors. A third of the Red Army command was dead by the own country’s hand. The consequence was that no officer moved was made without explicit instructions. Stalin even moved to remove rank and insignia. Every unit had a political officer who would monitor the soldiers for loyalty to Stalin. This would have consequences for the Red Army in Finland and later when the German Wehrmacht moved against the Red Army in June 1941. Paralyzed by fear and conflicting political directives, they would simply sit and wait for direction.
Stalin ordered no defensive fortifications to be built, since wars would only be fought on an enemy’s territory. Despite the Red Army’s failure in Finland, he believed in the invincibility of his leadership.
In reality he left the Soviet Union open to a major assault that would claim 20 million lives, in addition to those who died by his orders. Years of blood and death awaited his people.
