Mbh 10.8.11

"'While the camp was in this state, Rakshasas, O king, uttered loud roars in joy, O chief of the Bharatas! The loud noise, O king, uttered by ghostly beings in joy, filled all the points of the compass and the welkin. Hearing the wails of woe, elephants, steeds, breaking their cords, rushed hither and thither, crushing the combatants in the camp. As those animals rushed hither and thither, the dust raised by them made the night doubly dark. When that thick gloom set in, the warriors in the camp became perfectly stupefied; sires recognised not their sons, brothers recognised not their brothers. Elephants assailing riderless elephants, and steeds assailing riderless steeds, assailed and broke and crushed the people that stood in their way. Losing all order, combatants rushed and slew one another, and felling those that stood in their way, crushed them into pieces. Deprived of their senses and overcome with sleep, and enveloped in gloom, men, impelled by fate, slew their own comrades. The guards, leaving the gates they watched, and those at duty at the outposts leaving the posts they guarded, fled away for their lives, deprived of their senses and not knowing whither they proceeded. They slew one another, the slayers, O lord, not recognising the slain. Afflicted by Fate, they cried after their sires and sons. While they fled, abandoning their friends and relatives, they called upon one another, mentioning their families and names. Other, uttering cries of "Oh!" and "Alas!" fell down on the earth. In the midst of the battle, Drona's son, recognising them, slew them all.
