The Siege of Smolensk, known as the Smolensk Defense in Russia (Смоленская оборона in Russian) lasted 20 months between September of 1609 and June of 1611, when the Polish army besieged the Russian city of Smolensk during the Polish-Muscovite War (1605-1618).

In September of 1609, the Polish army under the command of King Sigismund III Vasa (22,000 men: 12,000 Polish soldiers and 10,000 Ukrainian Cossacks; 30 guns) approached Smolensk. The city was defended by the Russian garrison under the command of voyevoda Mikhail Borisovich Shein (over 5,000 men and 200 guns). On September 25-27, the invaders assaulted Smolensk for the first time with no result.

Between September 28 and October 4, the Poles were shelling the city and then decided to lay siege to it. On July 19–20, August 11, and September 21, the Polish army attacked Smolensk for the second, third, and fourth time, but to no avail. The siege, the shelling, and the assaults alternated with fruitless attempts of the Polish army to persuade the citizens of Smolensk to capitulate. Negotiations in September of 1610 and March of 1611 did not lead anywhere.

The largest sapping project at Smolensk came in December 1610; however, the Poles only managed to destroy a large portion of the outer wall, the inner walls remaining intact. The siege continued. At one point, the Polish guns breached the outer wall and the voivode of Bracław ordered his soldiers to rush in; however, the Russians could see where the breach would come and had fortified that part of the wall with more people. Both sides were slaughtered, and the Poles were eventually beaten back.

The citizens of Smolensk had been coping with starvation and epidemic since the summer of 1610. The weakened Russian garrison was not able to repel the fifth attack of the Polish army on June 3, 1611, when after the 20 months of siege the Polish army advised by the runaway traitor Andrei Dedishin, discovered a weakness in the fortress defence and on 13 June 1611 a Cavalier of Malta, Bartłomiej Nowodworski, inserted a mine into a sewer canal and the succeeding explosion created a large breach in the fortress walls. Jakub Potocki was the first on the walls. The fortress fell on the same day, with the last stage taking place after violent street fighting, when some 3,000 Russians soldiers blew themselves up in the Assumption Cathedral. Wounded Mikhail Shein was taken prisoner and would remain a prisoner of Poland-Lithuania for the next 9 years.

Although it was a blow to lose Smolensk, it freed up Russian troops to fight the Commonwealth in Moscow, whereas Shein came to be considered a hero for holding out as long as he had. Smolensk would become the place of two more sieges later in this war: of 1612 and 1617.
