False Dmitry II
A combined Russo-Swedish army of about 10,000 soldiers set out from Novgorod in April 1609 and marched towards Moscow, defeating rebel forces and relieving the Siege of Troitse-Sergiyeva Lavra on their way. The De la Gardie campaign was successful against False Dmitry II, dispersing his court in Tushino, a former village and town to the north of Moscow, where Dmitry II maintained an alternative court, challenging the authority of Vasili IV. On 12 March 1610, the Russo-Swedish army broke the rebel siege of Moscow and conquered the city.
