"Vaisampayana continued, 'Then, O Lord of earth, those warriors, the Trigartas, accompanied by their infantry of terrible prowess, marched towards the south-eastern direction, intending to wage hostilities with Virata from the desire of seizing his kine. And Susarman set out on the seventh day of the dark fortnight for seizing the kine. And then, O king, on the eighth day following of the dark fortnight, the Kauravas also accompanied by all their troops, began to seize the kine by thousands."
