Jebe had made a legendary raid around the Caspian Sea where he and Subutai defeated the Georgians, who were set to join the fifth crusade, as well as the Caucasus Steppe tribes. He then later went on to defeat the Kievan Rus' and Cumans at the Battle of the Kalka River. This battle preceded the conquest of Kievan Rus' and he likely died on his return from the conquests of the Kievan Rus' in approximately 1224. The circumstances surrounding his disappearance and death are mysterious. One scholar, Stephen Pow suggests that Jebe may have been killed by the Russian allied Kipchaks forces near a kurgan close to Khortytsia Island. The discrepancy behind this information may be a result of linguistic errors since the Turkic-speaking Kipchaks referred to Jebe as Gemya-Beg. But Russian scholars, D.M. Timokhin and V.V. Tishin questioned his views, they believe that the version of Stephen Pow is not proven on the basis of written sources and has absolutely no linguistic evidence. Although the circumstances around his death is mysterious, Jebe left an indelible mark on history with his conquests in China, Central Asia, and Europe at Kiev and the Rus.
