Ironically, perhaps, Sambhuvarman's reign was marred by one of the most devastating invasions ever suffered by the country of Champa. In 605 AD, the Chinese general Liu Fang led an army southwards from the area of what is now northern Vietnam, defeated the elephant-riders of Sambhuvarman, and sacked the Cham capital, making off with an enormous booty that included over one thousand Buddhist books as well as the gold tablets commemorating the reigns of the previous eighteen kings. Heading back north with their heist, the Chinese invaders were struck by an epidemic that felled a large number of them, including Liu Fang. Sambhuvarman, for his part, returned home to his kingdom, began the process of rebuilding, and made sure to send regular shipments of tribute to the Chinese court, in order through appeasement to prevent a recurrence of the recent disaster.
