In September 1609, the Polish army under the command of King Sigismund III Vasa the attackers approached Smolensk. The city was defended by the Russian garrison under the command of voyevodaMikhail Borisovich Shein. On 25–27 September, the invaders assaulted Smolensk for the first time with no result. Between 28 September and 4 October, the Poles were shelling the city and then decided to lay siege to it. On 19–20 July, 11 August, and 21 September, 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 1610 and March 1611 did not lead anywhere. The largest mining 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.
Russian demise
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 3 June 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,, inserted a mine into a sewer canal and the succeeding explosion created a large breach in the fortress walls. 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 citizens blew themselves up in the Assumption Cathedral. The wounded Mikhail Shein was taken prisoner and would remain a prisoner of Poland for the next 9 years.
Aftermath
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 later become the place of a siege in 1612 and one in 1617.
