During the Red Terror, estimates of Cheka executions range from 12,733 to 1.7 million. William Henry Chamberlin suspected that there were about 50,000. Evan Mawdsley suspected that there were more than 12,733, and less than 200,000. Some sources claimed at least 250,000 summary executions of "enemies of the people" with estimates reaching above a million. More modest estimates put the numbers executed by the Bolsheviks between December 1917 and February 1922 at around 28,000 per year, with roughly 10,000 executions during the Red Terror.
