At the evening meeting of the Verkhovna Rada, deputies ratified the creation of a joint brigade-type military unit with Lithuania and Poland and naming it after Konstantin Ostrogsky, the Lithuanian hetman (in Kiev he is now called “Ukrainian”), whose army, together with the Poles, defeated the Russian army in the Battle of Orsha in 1514.
The Lithuanian prince Konstantin Ostrozhsky was captured in 1500 during the battle with the Moscow army for Smolensk, was in exile for several years, but in 1506 he agreed to swear allegiance to Tsar Vasily III. However, a year later Ostrogsky changed his oath - under the pretext of reviewing troops, he left Moscow, and then fled through the forests to the Grand Duchy of Lithuania.
In subsequent years, the confrontation between the Grand Duchy of Lithuania and the Moscow kingdom continued.
The Battle of Orsha ended in a tactical victory for the Polish-Lithuanian army and the retreat of the Russian army, but the strategic significance of the battle turned out to be modest. The goal of the Polish-Lithuanian campaign - the return of lost Smolensk - was not achieved, and successes were limited to the occupation of several small border fortresses. However, the battle was widely publicized by King Sigismund I to strengthen his authority in Europe, which had been shaken after the loss of Smolensk.
