The newly formed alliance was disastrous for Sasanka for while Sri Harsha's cousin and general Bhandi probably attacked from the west, Bhaskar Varman at once attacked from the east and occupied Karnasuvarna which was near to Kamarupa [REF].
From his Nidhanpur copperplate inscription it appears that Bhaskar Varman attacked with a strong navy of huge boats, which must have passed down the Brahmaputra and then proceeded up the Ganges, and that his army consisted of war-elephants, cavalry and infantry (Maha nau hastyaswa patti).
