By the end of 1611, the Swedes, taking advantage of the difficult situation of Russia in connection with the Polish-Lithuanian intervention captured most of the Novgorod land including the fortresses of Korela, Yam and Ivangorod.

[1] The first attempt to take Oreshek took place in February 1611, when De la Gardie ordered the fortress to be stormed, blowing up two front gates with explosives.

However, the third iron gate, according to Johan Widekindi, proved too tough for the attackers and they retreated after losing 20 men.

[2] The second attempt began in September 1611, when the Swedes, having captured Ladoga, again sent significant forces to Oreshek and blocked its approaches, seeking to starve it out.

The new commander of the siege, the future Field Marshal Evert Horn, after November 30, offered the besieged "good terms" for surrender.
