Mbh 2.26.1a

Vaisampayana continued,--thus addressed, Dhananjaya replied unto Bhagadatta, saying,--‘If thou wilt give thy promise to do this, thou hast done all I desire. And having thus subjugated the king of Pragjyotisha, Dhananjaya of long arms, the son of Kunti, then marched towards the north--the direction presided over by the lord of treasures. That bull amongst men, that son of Kunti, then conquered the mountainous tracts and their outskirts, as also the hilly regions. And having conquered all the mountains and the kings that reigned there, and bringing them under his sway, he exacted tributes from all. And winning the affections of those kings and uniting himself with them, he next marched, O king, against Vrihanta, the king of Uluka, making this earth tremble with the sound of his drums, the clatter of his chariot-wheels, and the roar of the elephants in his train. Vrihanta, however, quickly coming out of his city followed by his army consisting of four kinds of troops, gave battle to Falguna (Arjuna). And the fight that took place between Vrihanta and Dhananjaya was terrible. It so happened that Vrihanta was unable to bear the prowess of the son of Pandu. Then that invincible king of the mountainous region regarding the son of Kunti irresistible, approached him with all his wealth. Arjuna snatched out the kingdom from Vrihanta, but having made peace with him marched, accompanied by that king, against Senavindu whom he soon expelled from his kingdom. After this he subjugated Modapura, Vamadeva, Sudaman, Susankula, the Northern Ulukas, and the kings of those countries and peoples. Hereafter at the command of Yudhishthira, O monarch, Arjuna, did not move from the city of Senavindu but sent his troops only and brought under his sway those five countries and peoples. For Arjuna, having arrived at Devaprastha, the city of Senavindu, took up his quarters there with his army consisting of four kinds of forces.
