Zhao Mo
In 135 BC, war broke out when Minyue invaded Nanyue. Zhao Mo, the king of Nanyue, asked for and received the military assistance of the Han. In 180 BC, Zhao had offered to submit as a vassal and the Han agreed, a decision that was partly based on Zhao's ancestral roots in northern China. An army led by the generals Wang Hui and Han Anguo was ordered to invade Minyue. The campaign was cut short by palace infighting in the Minyue court. Panicked at news of an invasion, the younger brother of the Minyue king Zou Ying, Zou Yushan, conspired with the royal court to depose Ying. Yushan killed his brother with a spear, decapitated the corpse, and sent the head to Wang. The Han forces withdrew soon after.
