Mbh 6.70.1a

Sanjaya said, “Then Bhishma the son of Santanu fought fiercely,[394] desirous of protecting thy sons from the fear of Bhimasena. And the battle that then took place between the kings of the Kaurava and the Pandava armies was awful in the extreme and destructive of great heroes. And in that general engagement, so fierce and terrible, tremendous was the din that arose, touching the very heavens. And in consequence of the shrieks of huge elephants and the neigh of steeds and the blare of conches and beat of drums, the uproar was deafening. Fighting for the sake of victory, the mighty combatants endued with great prowess roared at one another like bulls in a cow-pen. And heads cut off in that battle with keen-edged shafts, incessantly falling, created, O bull of Bharata’s race, the appearance of a stony shower in the welkin. Indeed, O bull of Bharata’s race, innumerable were the heads lying on the field of battle, decked with ear-rings and turbans and resplendent with ornaments of gold. And the earth was covered with limbs cut off with broad-headed shafts, with heads decked with ear-rings, and with arms adorned with ornaments. And in a moment the whole field was strewn over with bodies cased in mail, with arms decked with ornaments, with faces beautiful as the moon and having eyes with reddish corners, and with every limb, O king, of elephants, steeds and men. And the dust (raised by the warriors) looked like a thick cloud, and the bright implements of destruction, like flashes of lightning. And the noise made by the weapons resembled the roar of thunder. And that fierce and awful passage-at-arms, O Bharata, between the Kurus and the Pandavas caused a very river of blood to flow there. And in that terrible, fierce, and awful battle causing the hair stand on end, Kshatriya warriors incapable of defeat incessantly poured their arrowy showers.
