Mbh 13.30.4b

Issuing out of their capital, those tigers among men, viz., the sons of Vitahavya, who were all skilful warriors cased in mail, rushed with uplifted weapons towards Pratarddana, covering him with showers of arrows. Encompassing him with innumerable cars, O Yudhisthira, the Vitahavyas poured upon Pratarddana showers of weapons of various kinds like clouds pouring torrents of rain on the breast of Himavat. Baffling their weapons with his own, prince Pratarddana endued with mighty energy slew them all with his shafts that resembled the lighting fire of Indra. Their heads struck off, O king, with hundreds and thousands of broad-headed arrows, the warriors of Vitahavya fell down with blood-dyed bodies like Kinsuka trees felled by woodmen with their axes on every side. After all his warriors and sons had fallen in battle, king Vitahavya fled away from his capital to the retreat of Bhrigu. Indeed, arrived there, the royal fugitive sought the protection of Bhrigu. The Rishi Bhrigu, O monarch, assured the defeated king of his protection. Pratarddana followed in the footsteps of Vitahavya. Arrived at the Rishi's retreat, the son of Divodasa said in a loud voice.--'Ho, listen ye disciples of the high souled Bhrigu that may happen to be present, I wish to see the sage. Go and inform him of this. Recognising that it was Pratarddana who had come, the Rishi Bhrigu himself came out of his retreat and worshipped that best of kings according to due rites. Addressing him then, the Rishi said,--Tell me, O king, what is thy business.' The king, at this, informed the Rishi of the reason of his presence.'
