Mbh 7.187.1b

The blood of elephants and steeds and human beings formed its current. Weapons formed its fish in profusion. It was miry with blood and flesh. Wails of grief and pain formed its roar. Banners and cloth formed its froth. Afflicted with shafts and darts, worn with exertion, spent with toil on the (previous) night, and exceedingly weakened, elephants and steeds, with limbs perfectly motionless, stood on the field. With their arms (in beautiful attitudes) and with their beautiful coats of mail, and heads decked with beautiful ear-rings, the warriors, adorned with implements of battle, looked exceedingly resplendent.[250] At that time, in consequence of the carnivorous animals and the dead and the dying, there was no path for the cars all over the field. Afflicted with shafts steeds of the noblest breed and high mettle, resembling elephants (in size and strength), worn out with toil, were seen to tremble with great effort, as they drew vehicles whose wheels had sunk in the earth. The whole of that host, O Bharata, resembling the ocean for vastness, then became agitated, and afflicted, inspired with terror, with the exception only of Drona and Arjuna. Those two became the refuge, these two became the saviours, of the warriors of their respective sides. Others, encountering these two proceeded to the abode of Yama. Then the vast host of the Kurus became greatly agitated, and the Panchalas, huddled together, became no longer distinguishable.
