Mbh 6.91.1c

Then when those cavalry divisions were thinned and a remnant only survived, the younger brothers of Suvala’s son, possessed of great wisdom, rode out, O Bharata (from the Kaurava array) to the van of battle, mounted on excellent chargers that resembled the tempest itself in both fleetness and the violence of their dash and that were well-trained and neither old nor young.[440] Those six brothers endued with great strength, viz., Gaya, Gavaksha, Vrishava, Charmavat, Arjava, and Suka dashed out of the mighty (Kaurava) array, supported by Sakuni and by their respective forces of great valour, themselves clad in mail, skilled in battle, fierce in mien, and possessed of exceeding might. Breaking through that invincible cavalry division (of the Pandavas), O thou of mighty arms, those Gandhara warriors who could with difficulty be vanquished, supported by a large force, desirous of heaven, longing for victory, and filled with delight, penetrated into it. Beholding them filled with joy, the valiant Iravat, addressing his own warriors decked with diverse ornaments and weapons, said unto them, ‘Adopt such contrivances in consequence of which these Dhritarashtra warriors with their weapons and animals may all be destroyed.’ Saying ‘Yes’, all those warriors of Iravat began to slay those mighty and invincible Dhartarashtra soldiers. Beholding that their own warriors were thus overthrown by Iravat’s division, those sons of Suvala being unable to bear it coolly, all rushed at Iravat and surrounded him on all sides. And commanding (all their followers) to attack those of Iravat with lances, those heroes swept over the field, creating a great confusion. And Iravat, pierced with lances by those high-souled warriors, and bathed in blood that trickled down (his wounds), looked like an elephant pierced with the hook. Wounded deeply on the chest, back, and flanks, singly encountering the many, he did not yet, O king, swerve from his (natural) firmness.
