Mbh 8.46.3a

"Sanjaya said, 'Hear now of the formation of the arrays, the manner in which Arjuna came and how the battle was fought by both sides surrounding their respective kings. Sharadvata's son Kripa, O king, and the Magadhas endued with great activity, and Kritavarma of Satwata race, took up their position in the right wing. Shakuni, and the mighty car-warrior Uluka, standing on the right of these, and accompanied by many fearless Gandhara horsemen armed with bright lances, and many mountaineers difficult to defeat, numerous as flights of locusts, and grim looking as Pishacas, protected the (Kaurava) army. 34,000 unreturning cars of the samsaptakas, mad with desire of battle, with thy sons in their midst, and all desirous of slaying Krishna and Arjuna, protected the left side (of the Kaurava army). On their left, the Kambojas, the Sakas, and the Yavanas, with cars and horse and foot, at the command of the Suta's son, stood, challenging Arjuna and the mighty Keshava. In the centre, at the head of that host, stood Karna, clad in armour with beautiful coat of mail and adorned with Angadas and garlands, for protecting that point. Supported by his own angry sons, that foremost of all wielders of weapons, that hero, shone resplendent at the head of the army as he drew his bow repeatedly. The mighty-armed Duhshasana, possessed of the effulgence of the sun or fire with tawny eyes and handsome features, riding on the neck of a huge elephant, surrounded by many troops, and stationed at the rear of the army gradually approached for fight. Behind him came Duryodhana himself, O monarch, protected by his uterine brothers riding on beautiful steeds and cased in beautiful mail. Protected by the united Madrakas and the Kekayas of exceeding energy, the king, O monarch, looked resplendent like Indra of a hundred sacrifices when surrounded by the celestials.
