About the battle

The siege of Opochka was an unsuccessful attempt by the Grand Duchy of Lithuania and the Kingdom of Poland to conquer the Russian fortress of Opochka during the Fourth Muscovite–Lithuanian War.

Russian troops were able to successfully defend the fortress and inflict heavy damage on the Poles and Lithuanians, avenging the defeat at Orsha three years ago. The replies of the Polish king Sigismund did not describe the course of the siege, but the invented battle of Opochka, where the Russians allegedly lost.
