The Russian counteroffensive failed to regain Novgorod, however. The Russian tsar refused to commit his troops to battle, and the war lumbered on until 1614 when the Swedes captured Gdov. The following year, they laid siege to Pskov but Russian Generals Morozov and Buturlin held their own until 27 February 1617 when the Treaty of Stolbovo stripped Russia of its access to the Baltic Sea and awarded to Sweden the province of Ingria with the townships of Ivangorod, Jama, Koporye, and Noteborg. Novgorod and Gdov were to be restored to Russia. As a result of the war, Russia was denied access to the Baltic sea for about a century, despite its persistent efforts to reverse the situation. That led to the increased importance of Arkhangelsk for its trading connections with Western Europe. References Citations Sources Further reading Göransson, Göte (1994) Gustav II Adolf och hans folk.
