Mbh 8.81.1c

Fierce as the death-night, subsisting upon men and elephants and steeds as its food, and capable of crushing walls and mansions and gates of cities, that exceedingly terrible mace of Bhima incessantly descended on men and elephants and steeds around him. That mace, O sire, slew numberless steeds and riders. With that mace the son of Pandu crushed men and steeds cased in steel armour. Struck therewith, they fell down with great noise. Biting the earth with their teeth, and bathed in blood, these, with the crowns of their heads and bows and lower limbs crushed, laid themselves down on the field, supplying all carnivorous creatures with food. Satiated with blood and flesh and marrow, and eating bones as well, that mace (of Bhimasena) became, like the death-night, difficult of being gazed at. Having slain 10,000 horses and numerous foot-soldiers, Bhima ran hither and thither in rage, armed with his mace. Then, O Bharata, thy troops, beholding Bhima mace in hand, thought that Yama himself, armed with his fatal bludgeon, was in their midst. The son of Pandu then, excited with rage, and resembling an infuriated elephant, penetrated into the elephant division (of the Kauravas), like a Makara entering the ocean. Having, with his formidable mace, penetrated into that elephant division, the enraged Bhima, within a very short time, despatched it to Yama's abode. We then beheld those infuriated elephants with spiked plates on their bodies falling on every side, with their riders and standards, like winged mountains. Having destroyed that elephant division, the mighty Bhimasena, once more riding on his car, followed Arjuna at his rear. That great host, thus slaughtered, filled with cheerlessness and about to fly away, stood almost inactive, O monarch, assailed on all sides with weapons. Beholding that host looking humble and standing inactive and almost motionless, Arjuna covered it with life-scorching shafts.
