Mbh 8.60.1f

There the Pancalas of great speed, O Dhananjaya, are rushing against the riderless Dhartarashtra elephants and steeds and cars. Reckless of their very lives, O chastiser of foes, those warriors, difficult of defeat in battle aided by the might of Bhimasena are crushing, O tiger among men, the hostile force. There, the Pancalas are uttering loud roars and blowing their conchs as they are rushing against their foes and crushing them with their shafts in battle. Behold their great energy and power. Through sheer valour, the Pancalas are slaughtering the Dhartarashtras like angry lions slaying elephants. Unarmed they are snatching the weapons of their armed foes and with those weapons thus snatched, they are slaying their foes that are effectual smiters, and uttering loud roars. The heads and arms of their foes are being struck off and felled on the field. The Pancala cars and elephants and horses are all worthy of the highest praise. Like swans of great speed leaving the Manasa lake and rushing into the Ganga, the Pancalas are rushing against the Kauravas, and every part of the vast Dhartarashtra force is assailed by them. Like bulls resisting bulls, the heroic Kripa and Karna and other leaders are putting forth all their valour for resisting the Pancalas. The Pancala heroes headed by Dhrishtadyumna are slaying thousands of their foes, viz., the great car-warriors of the Dhartarashtra army already sinking in the ocean of Bhima's weapons. Beholding the Pancalas overwhelmed by their foes, the fearless son of the Wind-god, assailing the hostile force, is shooting his shafts and uttering loud roars. The greater portion of the vast Dhartarashtra army has become exceedingly frightened. Behold those elephants, pierced by Bhima with his cloth-yard shafts, are falling down like mountain summits riven by the thunderbolt of Indra. There, those huge elephants, deeply pierced with the straight shafts of Bhimasena are flying away, crushing their own ranks.
