Mahabharata Stri Parva Chapter 27:2

Mahabharata Stri Parva (Vilapa Parva) Chapter 27:2 How was that foremost of mighty men, that first of car-warriors, who endured the united force of all lords of earth in battle, how was he a son of thine? Was that foremost of all wielders of weapons our eldest brother? How didst thou bring forth that child of wonderful prowess? Alas, in consequence of the concealment of this affair by thee, we have been undone! By the death of Karna, ourselves with all our friends have been exceedingly afflicted. The grief I feel at Karna's death is a hundred times greater than that which was caused by the death of Abhimanyu and the sons of Draupadi, and the destruction of the Pancalas and the Kurus. Thinking of Karna, I am burning with grief, like a person thrown into a blazing fire. Nothing could have been unattainable by us, not excepting things belonging to heaven. Alas, this terrible carnage, so destructive of the Kurus, would not have occurred.' Copiously indulging in lamentations like these, king Yudhishthira the just uttered loud wails of woe. The puissant monarch then offered oblations of water unto his deceased elder brother. Then all the ladies that crowded the shores of the river suddenly sent up a loud wail of grief. The intelligent king of the Kurus, Yudhishthira, caused the wives and members of Karna's family to be brought before him. Of righteous soul, he performed, with them, the water-rite in honour of his eldest brother. Having finished the ceremony, the king with his senses exceedingly agitated, rose from the waters of Ganga."
