Mbh 7.94.1b

Like an immovable hill resisting the fiercest current of water, Drona, however, resisted in that battle the enraged Pandavas and Panchalas and Kekayas. Many other kings also, endued with great strength and courage, attacking them from all sides, began to resist the Pandavas. Then that tiger among men, viz., the son of Prishata, uniting with the Pandavas, began repeatedly to strike Drona, for piercing the hostile host. Indeed, as Drona showered his arrows on Prishata’s son, even so did the latter shower his on Drona. Having scimitars and swords for the winds that blew before it, well-equipped with darts and lances and sabres, with the bow-string constituting its lightning, and the (twang of the) bow for its roars, the Dhrishtadyumna-cloud poured on all sides torrents of weapons, as its showers of stones. Slaying the foremost of car-warriors and a large number of steeds, the son of Prishata seemed to deluge the hostile divisions (with his arrowy downpours). And the son of Prishata, by his arrows, turned Drona away from all those tracks amid the car-divisions of the Pandavas, through which that hero attempted to pass, striking the warriors there with his shafts. And although Drona struggled vigorously in that battle, yet his host, encountering Dhrishtadyumna, became divided into three columns. One of these retreated towards Kritavarman, the chief of the Bhojas; another towards Jalasandha; and fiercely slaughtered the while by the Pandavas, proceeded towards Drona himself. Drona, that foremost of car-warriors, repeatedly united his troops. The mighty warrior Dhrishtadyumna as often smote and separated them. Indeed, the Dhartarashtra force, divided into three bodies, was slaughtered by the Pandavas and the Srinjayas fiercely, like a herd of cattle in the woods by many beasts of prey, when unprotected by herdsmen. And people thought that in that dreadful battle, it was Death himself who was swallowing the warriors first stupefied by Dhrishtadyumna.
