<human>:  Why did the Mongols lose at the Battle of Khawilghur?
<bot>: The Mongols lost because they didn’t have enough horses. The Mongol army had a lot of horses, but they didn’t have enough of them. When you don’t have enough horses, you can’t move fast. The Mongol army was moving so slowly that their enemies could attack them in small groups, which caused them to lose many of their battles.
