“The Pandavas, hearing the terrible wail of the beaten host, reverentially saluted Drona and ascended their chariots. Then Arjuna hastily bidding Yudhishthira not to engage in the fight, rushed forward, appointing the sons of Madri (Nakula and Sahadeva) the protectors of his chariot-wheels, while Bhimasena ever fighting in the van, mace in hand, ran ahead. The sinless Arjuna, thus accompanied by his brothers, hearing the shouts of the enemy, advanced towards them, filling the whole region with the rattle of his chariot-wheels. And like a Makara entering the sea, the mighty-armed Bhima, resembling a second Yama, mace in hand, entered the Panchala ranks, fiercely roaring like the ocean in a tempest. And Bhima, mace in hand, first rushed towards the array of elephants in the hostile force, while Arjuna, proficient in battle, assailed that force with the prowess of his arms. And Bhima, like the great Destroyer himself, began to slay those elephants with his mace. Those huge animals, like unto mountains, struck with Bhima’s mace, had their heads broken into pieces. Covered with stream of blood, they began to fall upon the ground like cliffs loosened by thunder. And the Pandavas prostrated on the ground elephants and horses and cars by thousands and slew many foot-soldiers and many car-warriors. Indeed, as a herdsman in the woods driveth before him with his staff countless cattle with ease, so did Vrikodara drive before him the chariots and elephants of the hostile force.
