Eventually, as the war continued between Ariq Böke and his brother Kublai, the former's forces weakened. Kublai had powerful Mongol cavalry troops, Mongolian, Manchurian, Han, Kipchak and numerous Chinese and Goryeo infantry units. Kublai's supporter Kadan, a son of Ögedei, crushed Ariq Böke's force under General Alandar, and Ariq Böke twice lost control of the capital of Karakorum. Kublai also blockaded all trade to Mongolia from North China, in order to cut the food supply. Ariq Böke finally submitted to Kublai in 1263. He was imprisoned by Kublai and died mysteriously a few years after his surrender, leading to rumors that he had been secretly poisoned.
