Mbh 8.60.1b

The force of the heroic Duryodhana's shafts, or Drona's son's or Kripa's or Karna's would break down the very mountains. That scorcher of foes, viz., king Yudhishthira, was once compelled by Karna to turn his back upon the field. The son of Radha is endued with great might and great lightness of hand. Possessed of great skill, he is accomplished in battle. He is competent to afflict the eldest son of Pandu in fight, specially when he is united with the mighty and brave son of Dhritarashtra. Of rigid vows, when the son of Pritha (Yudhishthira) had been engaged in battle with all those warriors, other great car-warriors had struck him and contributed to his defeat. The king, O best of the Bharatas, is exceedingly emaciated in consequence of his fasts. He is endued with Brahma-force, but the puissant one is not endued with much of Kshatriya-might. Assailed, however, by Karna, the royal son of Pandu, Yudhishthira, that scorcher of foes, hath been placed in a situation of great peril. I think, O Partha, that king Yudhishthira has fallen. Indeed, since that chastiser of foes, the wrathful Bhimasena, coolly heareth the leonine roars of the frequently shouting Dhartarashtra's longing for victory and blowing their conchs, I think, O bull among men, that Pandu's son Yudhishthira is dead. Yonder Karna urges forward the mighty car-warriors of the Dhartarashtras towards the son of Pritha with the weapons called Sthunakarna, Indrasjaha and Pasupata, and with clubs and other weapons. The king, O Bharata, must be deeply afflicted and exceedingly weakened, because the Pancalas and the Pandavas, those foremost of all wielders of weapons, are seen to proceed with great speed towards him at a time when speed is of the highest moment like strong men rushing to the rescue of a person sinking in a bottomless sea. The king's standard is no longer visible. It has probably been struck down by Karna with his shafts.
