Mahabharata Drona Parva Chapter 24:3

Mahabharata Drona Parva (Dronabhisheka Parva) Chapter 24:3 That prodigious beast, then seizing the car of Sini's grandson, hurled it to a distance with great force. Yuyudhana, however, escaped by timely flight. His charioteer also, abandoning the large steeds of the Sindhu breed, yoked unto that car, quickly followed Satyaki and stood where the latter stopped. Meanwhile the elephant, quickly coming out of the circle of cars, began to throw down all the kings (that attempted to bar his course). These bulls among men, frightened out of their wits by that single elephant coursing swiftly, regarded it in that battle as multiplied into many. Indeed, Bhagadatta, mounted on that elephant of his, began to smite down the Pandavas, like the chief of the celestials mounted on Airavata smiting down the Danavas (in days of old). As the Panchalas fled in all directions, loud and awful was the noise that arose amongst them, made by their elephants and steeds. And while the Pandava troops were thus destroyed by Bhagadatta, Bhima, excited with rage, once more rushed against the ruler of the Pragjyotisha. The latter's elephant then frightened the steeds of advancing Bhima by drenching them with water spouted forth from its trunk, and thereupon those animals bore Bhima away from the field. Then Kriti's son, Ruchiparvan, mounted on his car, quickly rushed against Bhagadatta, scattering showers of arrows and advancing like the Destroyer himself. Then Bhagadatta, that ruler of the hilly regions, possessed of beautiful limbs, despatched Ruchiparvan with a straight shaft to Yama's abode. Upon the fall of the heroic Ruchiparvan, Subhadra's son and the sons of Draupadi, and Chekitana, and Dhrishtaketu, and Yuyutsu began to afflict the elephant. Desiring to slay that elephant, all those warriors, uttering loud shouts, began to pour their arrows on the animals, like the clouds drenching the earth with their watery down-pour. Urged then by its skilful rider with heel, hook, and toe the animal advanced quickly with trunk stretched, and eyes and cars fixed.
