Mbh 6.17.1a

Sanjaya said,--“Just as the holy Krishna-Dwaipayana Vyasa had said, in that very manner the kings of the Earth, mustered together, came to the encounter. On that day on which the battle commenced Soma approached the region of Pitris.[92] The seven large planets, as they appeared in the firmament, all looked blazing like fire.[93] The Sun, when he rose, seemed to be divided in twain. Besides, that luminary, as it appeared in the firmament, seemed to blaze forth in flames.[94] Carnivorous jackals and crows, expecting dead bodies to feast upon, began to utter fierce cries from all directions that seemed to be ablaze. Every day the old grandsire of the Kurus, and the son of Bharadwaja, rising from bed in the morning, with concentrated mind, said,--‘Victory to the sons of Pandu’--while those chastisers of foes used (at the same time) yet to fight for thy sake according to the pledge they had given. Thy father Devavrata, fully conversant with every duty, summoning all the kings, said these words (unto them). ‘Ye Kshatriyas, this broad door is open to you for entering heaven. Go ye through it to the region of Sakra and Brahman. The Rishis of olden times have showed you this eternal path.[95] Honour ye yourselves by engaging in battle with attentive minds. Nabhaga, and Yayati, and Mandhatri, and Nahusa, and Nriga, were crowned with success and obtained the highest region of bliss by feats like these. To die of disease at home is sin for a Kshatriya. The death he meets with in battle is his eternal duty.’--Thus addressed, O bull of Bharata’s race, by Bhishma, the kings, looking beautiful in their excellent cars, proceeded to the heads of their respective divisions. Only Vikartana’s son Karna, with his friends and relatives, O bull of Bharata’s race, laid aside his weapons in battle for the sake of Bhishma. Without Karna then, thy sons and all the kings on thy side proceeded, making the ten points of the horizon resound with their leonine roars.
