Mbh 7.201.7b

The elephants and other creatures of the land, scorched by the energy of that weapon, ran in fright, breathing heavily and desirous of protection against that terrible force. The very waters heated, the creatures residing in that element, O Bharata, became exceedingly uneasy and seemed to burn. From all the points of the compass, cardinal and subsidiary, from the firmament and the very earth, showers of sharp and fierce arrows fell and issued with the impetuosity of Garuda or the wind. Struck and burnt by those shafts of Aswatthaman that were all endued with the impetuosity of the thunder, the hostile warriors fell down like trees burnt down by a raging fire. Huge elephants, burnt by that weapon, fell down on the earth all around, uttering fierce cries loud as the rumblings of the clouds. Other huge elephants, scorched by that fire, ran hither and thither, and roared aloud in fear, as if in the midst of a forest conflagration. The steeds, O king, and the cars also, burnt by the energy of that weapon, looked, O sire, like the tops of trees burnt in a forest-fire. Thousands of cars fell down on all sides. Indeed, O Bharata, it seemed that the divine lord Agni burnt the (Pandava) host in that battle, like the Samvarta fire consuming everything at the end of the Yuga.
