Stalin issues Order No. 227—outlawing cowards
The order established that each front must create one to three penal battalions (Shtrafbats), which were sent to the most dangerous sections of the front lines. From 1942 to 1945, a total of 422,700 Red Army personnel were sentenced to penal battalions as a result of courts-martial. The order also directed that each army must create “blocking detachments” at the rear that would shoot “panic-mongers and cowards”. In the first three months, blocking detachments shot 1,000 penal troops and sent 24,000 to penal battalions. By October 1942, the idea of regular blocking detachments was quietly dropped.
