6.66.14

krośanti kuñjarāstatra śaravarṣapratāpitāḥ |
tāvakānāṃ pareṣāṃ ca saṃyuge bharatottama |
aśvāśca paryadhāvanta hatārohā diśo daśa || 14 ||

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. And the elephants of both thy army and the enemy's, afflicted with those arrowy showers, shrieked aloud and ran hither and thither in fury. And in consequence of (the twang of) bows, endued with great energy, of fierce and heroic warriors excited with fury, and of flapping of their bow-strings against their leathern fences, nothing could be distinguished. And all over the field which looked like a lake of blood, headless trunks stood up, and the kings bent upon slaying their foes, rushed to battle. And brave warriors of immeasurable energy and possessed of arms resembling stout bludgeons, slew one another with arrows and darts and maces and scimitars. And elephants, pierced with arrows and deprived of riders to guide them with hooks, and steeds destitute of riders, wildly ran in all directions. And many warriors, O best of the Bharatas, belonging to both thy army and that of the foe, deeply pierced with shafts jumped up and fell down.
