Mbh 6.94.1b

Listening to these words of his brother, Vrikodara, with great speed, proceeded, frightening all the kings with his leonine roars, with great impetuosity, O king, like the ocean itself during the period of the new full moon. Him followed Satyadhriti and Sauchiti difficult of being vanquished in battle, and Srenimat, and Vasudana and the powerful son of the ruler of Kasi, and many car-warriors headed by Abhimanyu, as also those mighty car-warriors, viz., the sons of Draupadi, and the valiant Kshatradeva, and Kshatradharman, and Nila, the ruler of the low countries, at the head of his own forces. And these surrounded the son of Hidimva with a large division of cars (for aiding him).[446] And they advanced to the rescue of Ghatotkacha, that prince of the Rakshasas, with the six thousand elephants, always infuriate and accomplished in smiting. And with their loud leonine roars, and the clatter of their car-wheels, and with the tread of their horse’s hoofs, they made the very earth to tremble. Hearing the din of those advancing warriors the faces of thy troops who were filled with anxiety in consequence of their fear of Bhimasena became pale. Leaving Ghatotkacha then they all fled away. Then commenced in that part of the field a dreadful battle between those high-souled warriors and thine, both of whom were unretreating. Mighty car-warriors, hurling diverse kinds of the weapons, chased and smote one another. That fierce battle striking terror into the hearts of the timid, was such that the different classes of combatants became entangled with one another. Horses engaged with elephants and foot-soldiers with car-warriors. And challenging one another, O king, they engaged in the fight.[447] And in consequence of that clash of cars, steeds, elephants, and foot-soldiers, a thick dust appeared, raised by the car-wheels and the tread (of those combatants and animals). And that dust, thick and of the colour of reddish smoke, shrouded the field of battle.
