Sworn brother and foe
Jamukha was Temüjin’s sworn brother (anda); as boys they ate and slept together and exchanged knucklebones and whistling arrows, yet later they became the chief rivals for the steppe, and at the Battle of the Thirteen Wings Jamukha once beat Temüjin badly and boiled his captives alive. In the end, abandoned by his own men, Jamukha was bound and handed over by his followers; Temüjin executed the men who had betrayed their master, then, by steppe custom, granted his sworn brother a bloodless death. All the cruelty and all the romance of steppe politics lie in the story of these two anda.
