After seizing control of the Russian government, the Bolsheviks were tasked with maintaining control over the country. Although they were outnumbered at times and lacked veteran military leadership, by 1921 the Bolsheviks had gained complete control. Fortunately for the Bolsheviks, throughout the civil war they were led by Lenin and Leon Trotsky.
In his leadership role, Lenin proved to be ruthless in his attempt to gain control. In 1918, he launched what would become known as the Red Terror. The Red Terror was a campaign of mass killings,torture, and mass oppression meant to eliminate the opposition in the civilian population. Lenin was always focused on what he thought was for the betterment of Russia. He provided the drive and energy needed for the Bolsheviks to have success. His leadership was crucial in the success of his party.
Trotsky was a Commissar for War in the Bolshevik government. He was a brilliant organizer and improvisor and created the Red Army from the Red Guards. Trotsky imposed a very strict command on the Red Army. Officers found guilty of forms of treachery were often executed. However, men who showed exceptional bravery and initiative were quickly promoted. At times of crisis, Trotsky would assume command of areas under direct threat. This inspired and encouraged his troops to victory.
