Mbh 9.6.1a

"Sanjaya said, 'On that table land at the foot of Himavat, those warriors, O monarch, delighting at the prospect of battle and assembled together, passed the night. Indeed, Shalya and Chitrasena and the mighty car-warrior Shakuni and Ashvatthama and Kripa and Kritavarma of the Satwata race, and Sushena and Arishtasena and Dhritasena of great energy and Jayatsena and all these kings passed the night there. After the heroic Karna had been slain in battle, thy sons, inspired with fright by the Pandavas desirous of victory, failed to obtain peace anywhere else than on the mountains of Himavat. All of them then, O king, who were resolved on battle, duly worshipped the king and said unto him, in the presence of Shalya, these words, "It behoveth thee to fight with the enemy, after having made some one the generalissimo of thy army, protected by whom in battle we will vanquish our foes." Then Duryodhana, without alighting from his car (proceeded towards) that foremost of car-warriors, that hero conversant with all the rules of battle (Ashvatthama), who resembled the Destroyer himself in battle.
