Mbh 8.56.3b

The Earth became strewn with car-warriors and horsemen and elephant-men and drivers and foot-soldiers and steeds and elephants all mangled with the shafts of Bhimasena. The army of Duryodhana, O king, cheerless and mangled and afflicted with the fear of Bhimasena, stood as if stupefied. Indeed that melancholy host stood motionless in that dreadful battle like the Ocean, O king, during a calm in autumn. Stupefied, that host stood even like the Ocean in calm. However endued with wrath and energy and might, the army of thy son then, divested of its pride, lost all its splendour. Indeed, thy host, whilst thus being slaughtered became drenched with gore and seemed to bathe in blood. The combatants, O chief of the Bharatas, drenched with blood, were seen to approach and slaughter one another. The Suta's son, filled with rage, routed the Pandava division, while Bhimasena in rage routed the Kurus. And both of them, while thus employed, looked exceedingly resplendent. During the progress of that fierce battle filling the spectators with wonder, Arjuna, that foremost of various persons, having slain a large number of samsaptakas in the midst of their array, addressed Vasudeva, saying, "This struggling force of samsaptakas, O Janardana, is broken. Those great car-warriors amongst the samsaptakas are flying away with their followers, unable to bear my shafts, like deer unable to bear the roar of the lion. The vast force of the Srinjayas also seems to break in this great battle. There that banner of the intelligent Karna, bearing the device of the elephant's rope, O Krishna, is seen in the midst of Yudhishthira's division, where he is careering with activity. The other great car-warriors (of our army) are incapable of vanquishing Karna. Thou knowest that Karna is possessed of great energy as regards prowess in battle. Proceed thither where Karna is routing our force. Avoiding (other warriors) in battle, proceed against the Suta's son, that mighty car-warrior.
