 Various historical secondary sources - Morgan, Chambers, Grousset - state that the Mongols actually defeated the Bulgars, Chambers even going so far as to say that the Bulgars had made up stories to tell the (recently crushed) Russians that they had beaten the Mongols and driven them from their territory.Whatever the case, after this battle the Mongols skirted the Urals defeating the Saxin tribes there and then moved south to defeat the eastern Cumans-Kipchaks-Kanglis, where their army was destroyed and their khagan killed; subsequently they were forced to pay a large tribute to the Mongols.This would hardly have been possible if the Mongol force had been severely damaged at the Battle of Samara Bend.
