Mbh 9.1.3a

Vaishampayana said, "After the fall of Karna, O king, Dhritarashtra's son Suyodhana was plunged deep into an ocean of grief and saw despair on every side. Indulging in incessant lamentations, saying, 'Alas, oh Karna! Alas, oh Karna!' he proceeded with great difficulty to his camp, accompanied by the unslaughtered remnant of the kings on his side. Thinking of the slaughter of the Suta's son, he could not obtain peace of mind, though comforted by those kings with excellent reasons inculcated by the scriptures. Regarding destiny and necessity to be all-powerful, the Kuru king firmly resolved on battle. Having duly made Shalya the generalissimo of his forces, that bull among kings, O monarch, proceeded for battle, accompanied by that unslaughtered remnant of his forces. Then, O chief of Bharata's race, a terrible battle took place between the troops of the Kurus and those of the Pandavas, resembling that between the gods and the Asuras. Then Shalya, O monarch, having made a great carnage in battle at last lost a large number of his troops and was slain by Yudhishthira at midday. Then king Duryodhana, having lost all his friends and kinsmen, fled away from the field of battle and penetrated into the depths of a terrible lake from fear of his enemies. On the afternoon of that day, Bhimasena, causing the lake to be encompassed by many mighty car-warriors, summoned Duryodhana and having obliged him to come out, slew him speedily, putting forth his strength. After Duryodhana's slaughter, the three car-warriors (of the Kuru side) that were still unslain (Ashvatthama and Kripa and Kritavarma), filled with rage, O monarch, slaughtered the Pancala troops in the night. On the next morning Sanjaya, having set out from the camp, entered the city (the Kuru capital), cheerless and filled with grief and sorrow. Having entered the city, the Suta Sanjaya, raising his arms in grief, and with limbs trembling, entered the palace of the king.
