Mbh 9.16.1d

At this, thy son sat down on the terrace of his car. When Duryodhana swooned away, Vrikodara once more, with razor-faced shaft, cut off the head of his driver from his trunk. The steeds of Duryodhana's car, deprived of their driver, ran wildly on all sides, O Bharata, dragging the car after them, at which loud wails arose (in the Kuru army). Then the mighty car-warrior Ashvatthama, and Kripa and Kritavarma, followed that car, desirous of rescuing thy son. The (Kaurava) troops (at sight of this) became exceedingly agitated. The followers of Duryodhana became terrified. At that time, the wielder of Gandiva, drawing his bow, began to slay them with his arrows. Then Yudhishthira, excited with rage, rushed against the ruler of the Madras, himself urging his steeds white as ivory and fleet as thought. We then saw something that was wonderful in Yudhishthira, the son of Kunti, for though very mild and soft, he then became exceedingly fierce. With eyes opened wide and body trembling in rage, the son of Kunti cut off hostile warriors in hundreds and thousands by means of his sharp shafts. Those amongst the soldiers against whom the eldest Pandava proceeded, were overthrown by him, O king, like mountain summits riven with thunder. Felling cars with steeds and drivers and standards and throwing down car-warriors in large numbers, Yudhishthira, without any assistance, began to sport there like a mighty wind destroying masses of clouds. Filled with rage, he destroyed steeds with riders and steeds without riders and foot-soldiers by thousands in that battle, like Rudra destroying living creatures (at the time of the universal dissolution). Having made the field empty by shooting his shafts on all sides, Yudhishthira rushed against the ruler of the Madras and said, "Wait, Wait!" Beholding the feats then of that hero of terrible deeds, all thy warriors became inspired with fear. Shalya, however, proceeded against him. Both of them filled with rage, blew their conchs.
