The Tayichi'ud enslaved Temüjin (reportedly with a cangue, a sort of portable stocks), but with the help of a sympathetic guard, the father of Chilaun (who later became a general of Genghis Khan), he was able to escape from the ger (yurt) in the middle of the night by hiding in a river crevice.[citation needed] It was around this time that Jelme and Bo'orchu, two of Genghis Khan's future generals, joined forces with him. Temüjin's reputation also became widespread after his escape from the Tayichi'ud.
