Mbh 9.9.1d

Having stupefied that army, Bhimasena and Dhananjaya blew their conchs and uttered leonine roars. As soon as they heard that loud peal, Dhrishtadyumna and Shikhandi, placing king Yudhishthira at their head, rushed against the ruler of the Madras. Exceedingly wonderful and terrible, O monarch, was the manner in which those heroes, unitedly and as separate bodies, then fought with Shalya. The two sons of Madri, endued with great activity, accomplished in weapons, and invincible in battle, proceeded with great speed against thy host, inspired with desire of victory. Then thy army, O bull of Bharata's race, mangled in diverse ways with shafts by the Pandavas eager for victory, began to fly away from the field. That host, thus struck and broken by firm bowmen, O monarch, fled away on all sides in the very sight of thy sons. Loud cries of "Oh!" and "Alas!" O Bharata, arose from among thy warriors, while some illustrious Kshatriyas among the routed combatants, desirous of victory, cried out saying, "Stop, stop!" For all that, those troops of thine, broken by the Pandavas, fled away, deserting on the field their dear sons and brothers and maternal, uncles and sister's sons and relatives by marriage and other kinsmen. Urging their steeds and elephants to greater speed, thousands of warriors fled away, O bull of Bharata's race, bent only upon their own safety.'"
