On their cars that resembled (fortified) towns, unto which were yoked steeds decked with ornaments, and which were graced with beautiful standards of variegated hue, those heroes wielding excellent bows and cased in beautiful coats of mail and owning excellent standards, entered the hostile army like lions entering one forest from another. Smiting one another, fierce and terrific was the battle that ensued between them and the foe, in which cars and elephants got entangled with one another. Cherishing feelings of hostility towards one another, the terrible battle in which they took part lasted for a short space of time about sunset, increasing the population of Yama’s kingdom. And car-warriors and horsemen by thousands were strewn over the field. And Bhishma the son of Santanu excited with wrath, began to slaughter the troops of the high-souled Pandavas with his straight shafts. And with his arrows he began to despatch the combatants of the Panchalas to the domains of Yama. And the grandsire, having thus broken the ranks of the Pandavas at last withdrew his troops and retired, O king, to his encampment. And king Yudhishthira also, beholding both Dhrishtadyumna and Vrikodara, smelt their heads, and filled with joy, retired to his tents.”
