The Battle of Mozhaysk was a series of battles at the final stage of the Polish-Muscovite War (1605–1618) on the western approaches to Moscow. These battles are part of the Moscow campaign of Władysław IV. During months of fighting, the Russian armies managed to maintain their combat capability and prevent the rapid seizure of Moscow. However, the threat of encirclement forced the Russian troops to retreat, opening the way for the enemy to the capital.
