Mbh 2.31.1a

Vaisampayana said,--“I shall now recite to you the deeds and triumphs of Nakula, and how that exalted one conquered the direction that had once been subjugated by Vasudeva. The intelligent Nakula, surrounded by a large host, set out from Khandavaprastha for the west, making this earth tremble with the shouts and the leonine roars of the warriors and the deep rattle of chariot wheels. And the hero first assailed the mountainous country called Rohitaka that was dear unto (the celestial generalissimo) Kartikeya and which was delightful and prosperous and full of kine and every kind of wealth and produce. And the encounter the son of Pandu had with the Mattamyurakas of that country was fierce. And the illustrious Nakula after this, subjugated the whole of the desert country and the region known as Sairishaka full of plenty, as also that other one called Mahetta. And the hero had a fierce encounter with the royal sage Akrosa. And the son of Pandu left that part of the country having subjugated the Dasarnas, the Sivis, the Trigartas, the Amvashtas, the Malavas, the five tribes of the Karnatas, and those twice born classes that were called the Madhyamakeyas and Vattadhanas. And making circuitous journey that bull among men then conquered the (Mlechcha) tribes called the Utsava-sanketas. And the illustrious hero soon brought under subjection the mighty Gramaniya that dwelt on the shore of the sea, and the Sudras and the Abhiras that dwelt on the banks of the Saraswati, and all those tribes that lived upon fisheries, and those also that dwelt on the mountains, and the whole of the country called after the five rivers, and the mountains called Amara, and the country called Uttarayotisha and the city of Divyakutta and the tribe called Dwarapala. And the son of Pandu, by sheer force, reduced to subjection the Ramathas, the Harahunas, and various kings of the west. And while staying there Nakula sent. O Bharata, messengers unto Vasudeva.
