Mbh 7.188.1a

“Sanjaya said, ‘Then Duhsasana, filled with wrath, rushed against Sahadeva, causing the earth to tremble with the fierce speed of his car. Madri’s son, however, that crusher of foes, with a broad-headed arrow, quickly cut off the head, decked with the head-gear of his rushing antagonist’s driver. From the celerity with which that act was accomplished by Sahadeva, neither Duhsasana nor any of the troops knew that the driver’s head had been cut off. The reins being no longer held by anybody, the steeds ran at their will. It was then that Duhsasana knew that his driver had been slain. Conversant with the management of steeds, that foremost of car-warriors, himself restraining his steeds in that battle fought beautifully and with great activity and skill. That feat of his was applauded by friends and foes, since riding on that driverless car, he careered fearlessly in that battle. Then Sahadeva pierced those steeds with keen shafts. Afflicted with those shafts, they quickly ran away, careering hither and thither. For catching hold of the reins, he once laid aside his bow, and then he took up his bow for using it, laying aside the reins. During those opportunities the son of Madri covered him with arrows. Then Karna, desirous of rescuing thy son, rushed to that spot. Thereupon, Vrikodara, with great care, pierced Karna in the chest and arms with three broad-headed shafts sped from his bow drawn to its fullest stretch. Struck with those shafts like a snake with a stick, Karna stopped and began to resist Bhimasena, shooting keen shafts. Thereupon, a fierce battle took place between Bhima and Radha’s son. Both of them roared like bulls, and the eyes of both were expanded (with rage). Excited with wrath, and rushing towards each other, with great speed, they roared at each other. Those two delighters in battle were then very close to each other. So near were they that they could not easily shoot their shafts at each other. Thereupon, an encounter with maces happened.
