How a massive Russian siege collapsed under the weight of its own desertions
In short: In 1632, Mikhail Shein led 25,000 modernized troops to reclaim Smolensk. But as the Polish-Lithuanian relief force approached, the Russian army began to disintegrate from within, driven by border raids and internal dissent, turning a powerful invasion into a desperate surrender.
The Siege of Smolensk (1632–16<0xE2><0x80><0x89>33) began on 28 October 1632, when Muscovite forces under Mikhail Borisovich Shein moved to reclaim territory lost in 1618. Shein’s army was a significant departure from traditional Russian forces, featuring modernized regiments of dragoons, reiters, and infantry based on Western European models. At the start of the campaign, the Russian force was estimated at over 25,000 men, though the number of troops actually present at the siege fluctuated. By August 1633, the force had dwindled to approximately 20,000 as soldiers deserted to protect their estates from Crimean Tatar raids in South Russia.
The Polish-Lithuanian defenders, led by Samuel Drucki-Sokoliński, utilized advanced Italian-style bastions to hold the city. Despite heavy Russian artillery bombardment and the use of mines to damage city walls, the garrison—comprising roughly 3,000 regular soldiers, Cossacks, and local nobility—resisted for nearly a year. The tide turned when the newly elected King Władysław IV organized a massive relief effort, funded by a 6.5 million zloty tax contribution, the highest of his reign. This force included 24 chorągiews of Winged Hussars and over 12,000 infantry.
The siege broke on 4 October 1633, after Commonwealth forces overran Russian field fortifications. The Russian position became untenable as Shein’s camp was surrounded and his logistics disrupted by cavalry raids led by Krzysztof Radzi不上łł. Internal divisions further crippled the Muscovite effort; some historians point to dissent among Russian warlords, while others highlight the desertion of foreign mercenaries. Following negotiations that began in January 1634, Shein capitulated on 1 March 1634, leaving behind much of his artillery.
