51st Rifle Perekop Order of Lenin Red Banner Division named after the Moscow Soviet of Workers', Peasants', and Red Army Deputies.
On July 6, 1919, the commander of the troops of the 3rd Army of the Eastern Front, S. A. Mezheninov, issued Order No. 0158 to form the 51st Rifle Division from units of the Special Northern Expeditionary Detachment (commander S. V. Mrachkovsky), the Special Brigade (commander M. V. Vasiliev) of the 3rd Army, and the Vyatka Fortress Brigade.
The division was formed in Tyumen, where the 151st, 152nd, and 153rd brigades were organized in merchants' mansions on Beregovaya Street, Yamskaya Street, and in Trusovsky Lane. The division's organizational establishment was completed by August 15, 1919; on that day its commander, V. K. Blyukher, issued Order No. 1, which defined the division's organizational structure: headquarters, political department, supply department and other services; three rifle brigades with three rifle regiments each, numbered from the 451st to the 459th; signal and engineer battalions; a light artillery battery; and an armored automobile detachment. Blyukher himself arrived in Tyumen on August 19 and set up his headquarters in the house of the merchant Kolokolnikov.
During the final phase of the Petropavlovsk operation, the 151st Brigade was sent to Ishim, the 152nd, led by S. V. Mrachkovsky, moved toward Tobolsk, and the 153rd remained in reserve in Tyumen on Trusovsky Lane. After the defeat of A. V. Kolchak's Russian Army, the division was redeployed to Novonikolaevsk into the reserve of the RKKA High Command.
