The Khan supported the claim of Vasily II, but allowed Yury to take the appanage of his deceased younger brother, Peter of Dmitrov.

This decision did not fully satisfy Vasily, who took Dmitrov by force and expelled Yury's governor from the town in 1432.

This show of magnanimity cost him dearly, as scores of Muscovite boyars and noblemen fled to Vasily's court in Kolomna.

This shift in momentum impelled Yury to conclude a treaty with Vasily, whereby the uncle renounced his claims to Moscow, promised to deny assistance to his sons, and exchanged Dmitrov for other territories.

On 31 March 1434, on the Bright Week Wednesday, Yury again entered Moscow, where he captured Vasily's family and treasury.
