Mbh 4.33.1a

Vaisampayana said, “Then, O Bharata, when the world was enveloped in dust and the gloom of night, the warriors of both sides, without breaking the order of battle, desisted for a while.[31] And then, dispelling the darkness the moon arose illumining the night and gladdening the hearts of the Kshatriya warriors. And when everything became visible, the battle once more began. And it raged on so furiously that the combatants could not distinguish one another. And then Trigarta’s lord, Susarman with his younger brother, and accompanied by all his cars, rushed towards the king of Matsya. And descending from their cars, those bulls among Kshatriyas, the (royal) brothers, mace in hand, rushed furiously towards the cars of the foe. And the hostile hosts fiercely assailed each other with maces and swords and scimitars, battle-axes and bearded darts with keen edges and points of excellent temper. And king Susarman, the lord of the Trigartas having by his energy oppressed and defeated the whole army of the Matsyas, impetuously rushed towards Virata himself endued with great energy. And the two brothers having severally slain Virata’s two steeds and his charioteer, as also those soldiers that protected his rear, took him captive alive, when deprived of his car. Then afflicting him sorely, like a lustful man afflicting a defenceless damsel, Susarman placed Virata on his own car, and speedily rushed out of the field. And when the powerful Virata, deprived of his car, was taken captive, the Matsyas, harrassed solely by the Trigartas, began to flee in fear in all directions. And beholding them panic-stricken, Kunti’s son, Yudhishthira, addressed that subduer of foes, the mighty-armed Bhima, saying, ‘The king of the Matsyas hath been taken by the Trigartas. Do thou, O mighty-armed one, rescue him, so that he may not fall under the power of the enemy.
