The execution of General Tukhachevsky and the other seven generals severely weakened the Soviet military. This was first seen in the Red Army's disastrous performance in the Soviet-Finnish war of 1939-1940, in which the Soviet military suffered more than 100,000 dead or missing against a smaller and poorly-armed Finnish military. The loss of the eight generals, combined with the 1941 Red Army Purge, enabled the early astonishing successes of the German Wehrmacht in the 1941 Invasion of Russia, leading to severe loss of life and the devastation of most of the European section of the USSR.
