The first use of the barrier troops by the Red Army occurred in the late summer and fall on the Eastern front during the
Russian Civil War, when commander
Mikhail Tukhachevsky was authorized by War Commissar
Leon Trotsky of the Communist
Bolshevik government to station blocking detachments behind unreliable Red Army infantry regiments in the 1st Red Army, with orders to shoot if they either deserted or retreated without permission.
[1]
The concept was re-introduced on a large scale during the
Second World War.
[4] On June 27, 1941, in response to reports of unit disintegration in battle and desertion from the ranks in the Soviet Red Army, the 3rd Department (
military counterintelligence of Soviet Army) of the USSR's
Narkomat of Defense issued a directive creating mobile barrier forces composed of
NKVD personnel to operate on roads, railways, forests, etc. for the purpose of catching 'deserters and suspicious persons'. These forces were given the acronym
SMERSH (from the Russian
Smert shpionam - Death to spies).
[5][6] SMERSH detachments were created from
NKVD troops, augmented with counterintelligence operatives, and were under the command of the
NKVD.
[5]
With the continued deterioration of the military situation in the face of the German offensive of 1941, SMERSH and other NKVD punitive detachments acquired a new mission: to prevent the unauthorized withdrawal of Red Army forces from the battle line.
[5][6] The first troops of this kind were formed in the
Bryansk Front on September 5, 1941.
On September 12, 1941,
Joseph Stalin issued the
Stavka Directive No. 1919 (Директива Ставки ВГК №001919) concerning the creation of barrier troops in
rifle divisions of the
Southwestern Front, to suppress panic retreats. Each Red Army division was to have an anti-retreat detachment equipped with transport totalling one
company for each
regiment. Their primary goal was to maintain strict military discipline and to prevent disintegration of the front line by any means, including the use of machine guns to indiscriminately shoot any personnel retreating without authorization.
[7] These barrier troops were usually formed from ordinary military units, and placed under NKVD command.
In 1942, after the creation of
penal battalions by Stavka
Directive No. 227 (Директива Ставки ВГК №227), anti-retreat detachments were used to prevent withdrawal or desertion by penal units as well. However,
Penal military unit personnel were always rearguarded by NKVD or SMERSH anti-retreat detachments, and not by regular Red Army infantry forces.
[5] As per Order No. 227 each Army should have 3–5 barrier squads up to 200 persons each.
A report to Commissar General of State Security Lavrentiy Beria on October 10, 1941 noted that since the beginning of the war, NKVD anti-retreat troops had detained a total of 657,364 retreating or deserting personnel, of which 25,878 were arrested (of which 10,201 were sentenced to death by court martial and the rest were returned to active duty).[8]
