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. Then king Duryodhana, surrounded by a large division of Kalingas, and placing Bhishma ahead, rushed towards the Pandavas. And so the Pandava combatants also, supporting Vrikodara, and owning fleet animals, rushed, excited with rage, against Bhishma."
