1st Cavalry Army

The 1st Cavalry Army was the most famous Red Army сavalry formation. It was also known as Budyonny's Cavalry Army or simply as Konarmia ('Horsearmy').When the Russian Civil War broke out in 1918, a popular Сossack leader named Budyonny organized a small cavalry force in the Don region out of local Cossacks and common-place criminals. This force rapidly grew in numbers, sided with the Bolsheviks and eventually became the 1st Cavalry Army. It was transformed from a guerrilla force into a proper military unit under the command of Semyon Budyonny, and the political guidance of Kliment Voroshilov.
