Mbh 9.30.2

"Sanjaya said, 'After the flight of the ladies of those high-souled Kshatriyas, and after the (Kaurava) camp had become entirely empty, the three car-warriors (thou hast mentioned) became filled with anxiety. Hearing the shouts of the victorious sons of Pandu, and beholding the camp deserted towards the evening, those three warriors of our side, desirous of rescuing the king, and unable to stay on the field, proceeded towards the lake. Yudhishthira, of virtuous soul, with his brothers in that battle, felt great joy and wandered over the field from desire of slaying Duryodhana. Filled with wrath, the Pandavas, desirous of victory, searched for thy son. Though, however, they looked very carefully for him, they failed to discover the (Kuru) king. Mace in hand, he had fled with great speed from the field of battle and penetrated into that lake, having by the aid of his powers of illusion, solidified its waters. When at last the animals of the Pandavas became very much tired, the latter proceeded to their camp and rested there with their soldiers. After the Parthas had retired to their camp, Kripa and Drona's son and Kritavarma of the Satwata race, slowly proceeded towards that lake. Approaching the lake within which lay the king, they addressed that invincible ruler of men asleep within the water, saying, "Arise, O king, and fight with us against Yudhishthira! Either obtaining victory enjoy the earth, or, slain, proceed to heaven! The forces of the Pandavas also, O Duryodhana, have all been slain by thee! Those amongst them that are yet alive have been exceedingly mangled! They will not be able, O monarch, to bear thy impetuosity, especially when thou shalt be protected by us! Arise, therefore, O Bharata!"
