Bo'orchu

Bo'orchu (Боорчи, Boorchi) was one of the first and most loyal of Genghis Khan's friends and allies. He first met Genghis Khan as a boy. At that time, Genghis Khan, or Temujin, was looking for his stolen horses. Bo'orchu helped to win back the horses, and returned with Temujin to his father, Nakhu Bayan, who scolded him, having feared he was dead. Later, Temujin sent Hasar to get Bo'orchu and bring him to Temujin's camp.

After Temujin's wife, Börte, was taken captive by the Merkits and he was forced to flee, Bo'orchu was sent to spy on the Merkits with Belgutei and Jelme. After Temujin took the titles Genghis Khan and Great Khan of the Mongols, Bo'orchu was made head of the Khan's followers along with Jelme. He was rewarded again after Genghis Khan became Gurkhan.

When Genghis Khan was at Dalannemurges to fight the Tatars, heavy rain fell and Bo'orchu stood over the Khan with a felt sheet to shelter him. Genghis Khan later rewarded Bo'orchu for this deed, claiming he only moved his feet once during the night. Bo'orchu was later shot off his horse during a battle against Jamukha in the Khalakhaljid Sands. He stole an enemy horse and returned the next day, helping to find the enemy position. Bo'orchu was one of Ögedei's most trusted friends.
