Although many Polish nobles and soldiers were fighting for the second False Dmitry at the time, Sigismund III and the troops under his command did not support Dimitriy for the throne – Sigismund wanted Russia himself. The entry of Sigismund into Russia caused the majority of the Polish supporters of False Dmitry II to desert him and contributed to his defeat. A series of subsequent disasters induced False Dmitry II to flee his camp disguised as a peasant and to go to Kostroma together with Marina. Dmitry made another unsuccessful attack on Moscow, and, supported by the Don Cossacks, recovered a hold over all of south-eastern Russia. He was killed, however, while half drunk, on 11 December 1610 by a Qasim Tatar princeling Pyotr Urusov, whom Dimitriy had flogged on a previous occasion.
