Mbh 6.94.1c

And the combatants were unable to distinguish their own from the foe. Sire recognised not the son, and son recognised not the sire, in that dreadful engagement which made the hair stand on end and in which no consideration was shown (by any one for any body). And the noise made by the hissing weapons and the shouting combatants resembled, O chief of Bharata’s race, that made by departed spirits (in the infernal regions). And there flowed a river whose current consisted of the blood of elephants and steeds and men. And the hair (of the combatants) formed its weeds and moss. And in that battle heads falling from the trunks of men made a loud noise like that of a falling shower of stones. And the earth was strewn with the headless trunks of human beings, with mangled bodies of elephants and with the hacked limbs of steeds. And mighty car-warriors chased one another for smiting one another down, and hurled diverse kinds of weapons. Steeds, urged by their riders and falling upon steeds, dashed against one another and fell down deprived of life. And men, with eyes red in wrath, rushing against men and striking one another with their chests, smote one another down. And elephants, urged by their guides against hostile elephants, slew their compeers in that battle, with the points of their tusks. Covered with blood in consequence of their wounds and decked with standards (on their backs), elephants were entangled with elephants and looked like masses of clouds charged with lightning. And some amongst them mounted (by others) with the points of their tusks, and some with their frontal globes split with lances, ran hither and thither with loud shrieks like masses of roaring clouds. And some amongst them with their trunks lopped off,[448] and others with mangled limbs, dropped down in that dreadful battle like mountains shorn of their wings.
