Vytautas declares war to moghols (126)

In 1391, the scenario reached its climax as Timur attacked the Golden Horde and defeated Tokhtamysh at the Volga. Tamerlane sacked the capital,
Sarai Berke, vassalized the Golden Horde, and placed a puppet ruler on the thorne.

Tokhtamysh escaped to the Ukrainian steppes and asked for help from the Grand Duke Vytautas of Lithuania. In the great Battle of the Vorskla River (1399) the combined forces of Tokhtamysh and Vytautas were annihilated by two of Tamerlane's general, khan Temur Qutlugh and emir(murza visir) Edigu. The defeated Tokhtamysh was killed in Siberia by Edigu's men in 1406 or 1407.
