Mahabharata Drona Parva Chapter 24:4

Mahabharata Drona Parva (Dronabhisheka Parva) Chapter 24:4 Treading down Yuyutsu's steeds, the animal then slew the charioteer. Thereupon, O king, Yuyutsu, abandoning his car, fled away quickly. Then the Pandava warriors, desirous of slaying that prince of elephants, uttered loud shouts and covered it quickly with showers of arrows. At this time, thy son, excited with rage, rushed against the car of Subhadra's son. Meanwhile, king Bhagadatta on his elephant, shooting shafts on the foe, looked resplendent like the Sun himself scattering his rays on the earth. Arjuna's son then pierced him with a dozen shafts, and Yuyutsu with ten, and each of the sons of Draupadi pierced him with three shafts and Dhrishtaketu also pierced him with three. That elephant then, pierced with these shafts, shot with great care, looked resplendent like a mighty mass of clouds penetrated with the rays of the sun. Afflicted with those shafts of the foe, that elephant then, urged by its riders with skill and vigour, began to throw hostile warriors on both his flanks. Like a cowherd belabouring his cattle in the forest with a goad, Bhagadatta repeatedly smote the Pandava host. Like the cawing of quickly retreating crows when assailed by hawks, a loud and confused noise was heard among the Pandava troops who fled away with great speed. That prince of elephants, struck by its rider with hook, resembled, O king, a winged mountain of old. And it filled the hearts of the enemy with fear, like to what merchants experience at sight of the surging sea. Then elephants and car-warriors and steeds and kings, flying away in fear, made, as they fled, a loud and awful din that, O monarch, filled the earth and sky and heaven and the cardinal and subsidiary directions in that battle. Mounted on that foremost of elephants, king Bhagadatta penetrated the hostile army like the Asura Virochana in days of old into the celestial host in battle well-protected by the gods. A violent wind began to blow; a dusty cloud covered the sky and the troops; and people regarded that single elephant as multiplied into many, coursing all over the field.
