The turn occurred after the conclusion of the Shuisky alliance with the Swedes, alarmed by the strengthening of hostile Poland. On February 28, 1609, in
Vyborg, the young nephew of the Tsar,
Mikhail Skopin–Shuisky, signed an agreement with the Swedish King
Charles IX, who promised to provide an army in exchange for the Korelsky District and an alliance for the conquest of Livonia. On May 10, Skopin set out from Novgorod and moved towards Moscow, crushing Tushino troops on the way. In July, he defeated Sapega at
Kalyazin. On February 6, 1610, Sapega was forced to lift the
Siege of Trinity and retreat to
Dmitrov.
Polonization of the Tushino Camp For his part, the Polish King
Sigismund III, having presented as an excuse the clearly directed alliance of Russia with Sweden, invaded Moscow's possessions and in September
besieged Smolensk. Tushino Poles at first took this with irritation, immediately forming a confederation against the king and demanding that he leave the country, which they already considered their own. However,
Jan Peter Sapega did not join the confederation and demanded negotiations with the king – his position had a significant impact on the further course of affairs. For his part, Sigismund sent commissars to Tushino, headed by
Stanislav Stadnitsky, demanding help from them both from their subjects and offering them extensive rewards both from the Moscow treasury and in Poland; as for the Russians, they were promised the preservation of the faith and all customs and also rich rewards. This seemed tempting to the Tushino Poles, and negotiations began between them and the royal commissars, and not only Poles, but also many Russians began to lean on the king's side. The Pretender's attempt to remind himself and his "rights" provoked the following rebuff from Ruzhinsky: "What is it to you, why did the commissars come to me? God knows who you are? We have shed enough blood for you, but we see no benefit".
Kaluga Faction On December 10, the
Pretender tried to escape with four hundred Don Cossacks loyal to him, but was caught and de facto arrested by Rozhinsky. However, on December 27, 1609, he still fled to
Kaluga, disguised as a peasant and hiding in a sleigh with a plank (according to another version, even with manure). The Don Cossacks and part of the Poles under the leadership of Jan Tyshkevich, Rozhinsky's personal enemy, followed him (thus it came to a shootout between supporters of Tyshkevich and Rozhinsky). However, the Russian Tushinians immediately went in procession to the royal ambassadors, expressing their joy at getting rid of the "thief". On February 11, she fled to Dmitrov to Sapega, and from there to Kaluga and Marina Mnishek – on horseback in a hussar dress, accompanied by a servant and several Don Cossacks. At that time in Tushino itself the following was happening: Jan Tyshkevich brought from Kaluga a letter from the Pretender with promises, which caused a new ferment among the Poles; but Rozhinsky had already firmly taken the royal side and was leading the matter towards an agreement with Sigismund, for which an embassy was sent to Smolensk from the Poles and Russians, who entered into a confederation with the Poles and decided on their part to call the King's son
Vladislav (son of Sigismund) to the kingdom, subject to acceptance him Orthodoxy. This embassy was headed by Mikhail Saltykov, a prominent role in it was played by Fyodor Andropov and Prince Vasily Rubets–Masalsky; on January 31, they submitted to the King a draft treaty drawn up by Saltykov; in response, Sigismund proposed to the ambassadors a constitutional plan, according to which the
Zemsky Sobor and the Boyar Duma received the rights of an independent legislative, and the Duma at the same time – and the judiciary. The Tushino ambassadors accepted the conditions and swore allegiance, "As long as God gives us sovereign Vladislav for the Muscovite State", "to serve and direct and wish his sovereign father, the current most poignant King of Poland and Grand Duke of Lithuania Sigismund Ivanovich". In general, Sigismund, who made its complete reconciliation as a condition for the departure of his 15-year–old son to Moscow, was clearly trying to take the reins into his own hands. ==End of the Tushino Camp==
