The Battle Of Orsha was perhaps the most decisive moment of the Muscovite-Lithuanian Wars. The muscovites were confident that they could reunite the whole of the former Kievan Rus' lands, while the Lithuanians, alongside their polish allies, were a target of such expansionism. However, after being defeated at the Orsha, the muscovites would find themselves unable to make any decisive offensive manoeuvres against the lithuanians, and would eventually give up on trying to conquer the land directly. The lithuanian victory at the battle had a significant role in the creation of the Polish-Lithuanian Commonwealth, considering the expansion of religious tolerance (the orthodox nobility of Belarus had revolted and joined the muscovites in the battle).
But what if the lithuanians had been defeated and routed in the battle? Perhaps communications between muscovite generals Ivan Chelyadnin and Prince Bulgakov-Golitsa are better, or the lithuanians commit a mistake?
Would the muscovites be able to conquer Belarus? Or even Lithuania as a whole?
How would this affect the development of the polish-lithuanian dynastic union?
Would Muscovy gain an earlier reputation as a rising power after their victory in the battle?
What happens to the muscovite-allied Crimean Khanate?
