Then the king of Kāśī accompanied by all his army marched to attack the country of king Alarka. And forthwith forming a close union with the contiguous kings he attacked with some of their many vassals, and reduced him to subjection. And without harassing Alarka’s neighbouring kings by molesting their realms, he thus subjugated both the governors of the fortresses and the forest tribes. He reduced into submission some kings by bribes, and some by creating dissension, and others who were well-affected towards Alarka by conciliation.
