Mbh 8.47.2b

The encounter that took place when the Pancalas, the Cedis, and the Srinjayas faced thy troops was exceedingly fierce. Kripa and Kritavarma, and Shakuni the son of Subala, those heroes difficult of defeat in battle, accompanied by troops that were all cheerful, themselves filled with rage, and capable of smiting down thick ranks of cars, fought with the Koshalas, the Kasis, the Matsyas, the Karusas, the Kaikayas, and the Surasenas, all of whom were possessed of great courage. That battle fraught with great slaughter and destructive of body, life and sins, became conducive to fame, heaven, and virtue, in respect of the Kshatriya, the Vaishya, and the Shudra heroes that were engaged in it. Meanwhile the Kuru king Duryodhana with his brothers, O bull of Bharata's race, and supported by many Kuru heroes and many mighty Madraka car-warriors, protected Karna while the latter was engaged in battle with the Pandavas, the Pancalas, the Cedis, and Satyaki. Destroying that vast division with his sharp arrows, and crushing many foremost of car-warriors Karna succeeded in afflicting Yudhishthira. Cutting off the armour, the weapons, and the bodies of thousands of foes and slaying his foes by thousands and sending them to heaven and making them earn great fame, Karna caused his friends great joy. Thus, O sire, that battle destructive of men, steeds, and cars, between the Kurus and the Srinjayas, resembled the battle between the gods and the Asuras of old.'"
