沃爾斯克拉河
After his resounding defeat in the Battle of the Terek River, Tokhtamysh was deposed and replaced by Edigu, fleeing to the Ukrainian steppes and asking for help from Grand Duke Vytautas of Lithuania. The two combined their forces in the Battle of the Vorskla River in 1399, but were crushingly defeated by Khan Temur Qutlugh and Edigu, two of Timur's generals. Around 1406 Tokhtamysh was killed in Siberia by Edigu's men; Edigu, in turn, would be slain thirteen years later by one of Tokhtamysh's sons.
