Yes, of course. Stalin was a political commissar of Budienny's army but it was him who was mainly responsible for Budienny's disobedience.

Another error committed by the Soviet generals, which influenced the outcome of the war, neutralized the 1st Cavalry Army of Semyon Budyonny, a unit much feared by Pilsudski and other Polish commanders. Soviet High Command, at Tukhachevski's insistence, ordered the 1st Cavalry Army to march toward Warsaw from the south. Semyon Budyonny did not obey this order due to a grudge between commanding South-Western Front generals Aleksandr Yegorov and Tukhachevski. In addition, the political games of Joseph_Stalin who was at the time chief political commissar of the South-Western Front, further contributed to Yegorov's and Budyonny's disobedience. Joseph Stalin, in search of personal triumph, desired to capture the important industrial center of Lwów, besieged by Bolshevik forces but still resisting their assaults. Ultimately Budyonny's forces, which could have changed the course of the history, marched on Lwow instead of Warsaw and excluded themselves from the battle.
