Mbh 6.70.1b

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.[395] 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. And in that encounter between Bhima and Bhishma, heaps of arms and heads, as also of bows and maces and spiked clubs and hands and thighs, of legs and ornaments and bracelets, were seen lying over the field. And here and there over the field, O king, were seen large bodies of unretreating elephants and steeds and cars. And the Kshatriya warriors, urged on by fate, slew one another with maces, swords, lances, and straight shafts. And others endued with great heroism and accomplished in fight, encountered one another with their bare arms that resembled spiked clubs made of iron. And other heroic warriors of thy army, engaged with the combatants of the Pandava host, fought on slaying one another with clenched fists and knees, and slaps and blows, O king. And with the fallen and falling warriors and those weltering in agony on the ground, the field of battle everywhere became, O king, terrible to behold, and car-warriors, deprived of the cars and grasping excellent swords, rushed at one another, desirous of slaughter.
