In a raid around 1177, Temüjin was captured by his father's former allies, the Tayichi'ud, enslaved and, reportedly, humiliated by being shacked in a cangue (a form of portable stocks). With the help of a sympathetic guard, he escaped from the ger (yurt) at night by hiding in a river crevice. The escape earned Temüjin a reputation. Soon, Jelme and Bo'orchu joined forces with him, and they and the guard's son Chilaun eventually became generals of Genghis Khan.
