After the Russian Tsar Feodor I's death in 1598 began what in Russia is called Time of Troubles 1598-1613. As Fyodor had no heir, was the Russian throne vacant, and many were interested in it, among them Vasily Sjujskij supported by Sweden's King Charles IX.
As Karl did not want a Russian czar who was supported by Poland, he entered an agreement, in Viborg February 28, 1609, with Sjujskij: a Swedish army of 7000 man led by young field marshal Jacob De la Gardie would go into Russia, and Sjujskij put on the throne. Sweden would in return get Kexholm forever. The Swedish army would also receive 38,000 rubles a month in maintenance.
The first march was against Novgorod, where Sjujskijs nephew Mikhail Sjujskij waited. His army of 3000 men joined the Swedish. On May 2, the army broke up and marched on Moscow, which was under siege by people who were loyal to Dimitri (Dimitri was Fyodor II's younger brother who was murdered at a young age). Evert Horn and the army's vanguard took Staraya Russa. On May 12 arrived de la Gardie and the main army. Horn overtook and defeated the fleeing Russians at Kamenka May 15 On May 17, captured Horn Torzhok after a brilliant Swedish victory.
Then the Swedish army marched towards Tver. On July 13, the Battle of Tver ended with a Swedish victory. De la Gardie achieved what so many after him failed to do: to take Moscow.. He did this March 12, 1610 and was met with cheers from the Moscow residents.
In June 1610 left the De la Gardie and Dimitrij Sjuiskij Moscow to lift Stanisław Żółkiewskis siege of Smolensk. The active phase of the campaign ended with De la Gardie's army annihilated Żółkiewski army in the Battle of Klusjinoden June 25, 1610.
Peace accord was signed in what is called the De la Gardie fortune, two county (Livonia) south of Estonia and 100,000 riksdaler. (1 and 2 on the map)
The Swedes and Novgorod could now install Sjujskij that Tsar. Russia handed over the Kexholm to Sweden who also took the opportunity to buy Ingria for 65,000 rubel. (3 on the map)
Since my English is so bad, I wonder if you understand what I write?
Is there any idea to try to continue?
