Mbh 7.162.1

“Sanjaya said, ‘During the progress of that fierce and terrible battle, when the world was enveloped with darkness and dust, O king, the combatants, as they stood on the field, could not see one another. Those foremost of Kshatriyas fought with each other, guided by conjectures and the personal and other names (they uttered). And during the progress, O lord, of that terrible carnage of car-warriors and elephants and steeds and foot-soldiers[212], those heroes, viz., Drona and Karna and Kripa, and Bhima and Prishata’s son and Satwata, afflicted one another and the troops of either party, O bull of Bharata’s race. The combatants of both armies, oppressed all around by those foremost of car-warriors, during the hour of darkness, fled away on all sides. Indeed, the warriors, broke and fled away in all directions with hearts perfectly cheerless. And as they fled away in all directions, they underwent a great carnage. Thousands of foremost car-warriors also, O king, slaughtered one another in that battle. Unable to see anything in the dark, the combatants became deprived of their senses. All this was the result of the evil counsels of thy son. Indeed, at that hour when the world was enveloped in darkness, all creatures, O Bharata, including even the foremost of warriors, overcome with panic, were deprived of their senses in that battle.’[213]
