Mbh 9.9.1c

Elephant divisions, O monarch, slaughtered by high-souled warriors, dispersed in all directions like wind-tossed clouds. Those elephants, looking like clouds, fell down on the Earth, like mountains riven with thunder, O lord, on the occasion of the dissolution of the world at the end of the Yuga. Heaps upon heaps, looking like mountains, were seen, lying on the ground, of fallen steeds with their riders. A river appeared on the field of battle, flowing towards the other world. Blood formed its waters and cars its eddies. Standards formed its trees, and bones its pebbles. The arms (of combatants) were its alligators, bows its current, elephants its large rocks, and steeds its smaller ones. Fat and marrow formed its mire, umbrellas its swans, and maces its rafts. Abounding with armour and head-gears, banners constituted its beautiful trees. Teeming with wheels that formed its swarms of Chakravakas, it was covered with Trivenus and Dandas. Inspiring the brave with delight and enhancing the fears of the timid, that fierce river set in, whose shores abounded with Kurus and Srinjayas. Those brave warriors, with arms resembling spiked bludgeons, by the aid of their vehicles and animals serving the purposes of rafts and boats, crossed that awful river which ran towards the region of the dead. During the progress of that battle, O monarch, in which no consideration was shown by anybody for anyone, and which, fraught with awful destruction of the four kinds of forces, therefore, resembled the battle between the gods and the Asuras in days of old, some among the combatants, O scorcher of foes, loudly called upon their kinsmen and friends. Some, called upon by crying kinsmen, returned, afflicted with fear. During the progress of that fierce and awful battle, Arjuna and Bhimasena stupefied their foes. That vast host of thine, O ruler of men, thus slaughtered, swooned away on the field, like a woman under the influence of liquor.
