Purge of the army

The purge of the Red Army and Military Maritime Fleet removed three of five marshals (then equivalent to four-star generals), 13 of 15 army commanders (then equivalent to three-star generals), eight of nine admirals (the purge fell heavily on the Navy, who were suspected of exploiting their opportunities for foreign contacts), 50 of 57 army corps commanders, 154 out of 186 division commanders, 16 of 16 army commissars, and 25 of 28 army corps commissars.

At first, it was thought 25–50% of Red Army officers had been purged; the true figure is now known to be in the area of 3.7–7.7%. This discrepancy was the result of a systematic underestimation of the true size of the Red Army officer corps, and it was overlooked that most of those purged were merely expelled from the Party. Thirty percent of officers purged in 1937–1939 were allowed to return to service.

The purge of the army was claimed to be supported by German-forged documents (said to have been correspondence between Marshal Tukhachevsky and members of the German high command). The claim is unsupported by facts, as by the time the documents were supposedly created, two people from the eight in the Tukhachevsky group were already imprisoned, and by the time the document was said to reach Stalin the purging process was already underway. However the actual evidence introduced at trial was obtained from forced confessions.

The purge had a significant effect on German decision making in World War II: many German generals opposed an invasion of Russia, but Hitler disagreed, arguing that the Red Army was less effective after its intellectual leadership had been eliminated in the purge.
