Ivan III of Russia launched the second Muscovite–Lithuanian War in 1500, inflicting a major defeat on Lithuania at the Battle of Vedrosha. Smolensk, a strategically vital fortress held by Lithuania since 1404, became a primary Russian objective. Regent Stanisław Kiszka ordered improvements to the Smolensk Kremlin, ensuring the city was well-fortified before Russian forces arrived.
A Russian army under Dmitry Ivanovich Zhilka plundered Orsha and Vitebsk before besieging Smolensk in June 1502. An assault on 16 September was repelled and turned into a Lithuanian counterattack. The bloody but indecisive Battle of Lake Smolino, combined with reinforcements led by Great Hetman Stanislovas Kęsgaila, forced the Russians to retreat, ending the siege unsuccessfully.
Peace negotiations began even while Russian forces remained near Smolensk. A six-year truce signed on 25 March 1503 compelled Lithuania to surrender approximately 210,000 square kilometres—about a third of its territory—including Chernihiv and Novhorod-Siverskyi. Kiszka was promoted to Great Hetman in recognition of the defense; Russia eventually captured Smolensk in 1514.
