In 1395, Timur launched his final assault on the Golden Horde. He decisively routed Tokhtamysh in the Battle of the Terek river on 15 April 1395. All the major cities of the khanate were destroyed: Sarai, Ukek, Majar, Azaq, Tana and Astrakhan. Timur's raid was of service to the Russian prince as it damaged the Golden Horde, which for the next twelve years was in a state of anarchy. During the whole of this time no tribute was paid to the khan, Olug Moxammat, though vast sums of money were collected in the Moscow treasury for military purposes.
