Mahabharata Drona Parva Chapter 15:2

Mahabharata Drona Parva (Dronabhisheka Parva) Chapter 15:2 Like two large tigers attacking each other with their claws, or like two mighty elephants with their tusks, those mighty warriors coursed in circles, encountering each other with those two foremost of maces, and soon covered with blood, those two illustrious warriors seemed to resemble a couple of flowering Kinsukas. And the blows, loud as Indra's thunder, of the maces wielded by those two lions among men were heard on all sides. Struck by the ruler of Madras with his mace on both the left and the right side, Bhima moved not in the least, like a hill riven by the thunder. Similarly, the mighty ruler of Madras, struck by Bhima with his mace, patiently stood still like a hill struck with the thunder. Both of them, with upraised maces, endued as they were with great impetus, fell upon each other, coursing in shorter circles. Quickly nearing each other, then by eight steps and falling upon each other like two elephants, they suddenly struck each other with those maces of theirs made entirely of iron. And each of those heroes, in consequence of the other's impetuosity and violence being struck with each other's mace, fell down at the same instant of time like a couple of Indra's poles. Then the mighty car-warrior Kritavarman quickly approached Salya who, deprived of his senses, was breathing hard as he lay on the field. And beholding him, O king, struck violently with the mace, and writhing like a snake, and deprived of his senses in a swoon, the mighty car-warrior Kritavarman, taking him upon his car, quickly bore the ruler of Madras away from the field. Reeling like a drunken man, the heroic Bhima of mighty arms, rising up within the twinkling of an eye, stood mace in hand. Thy sons then, beholding the ruler of the Madras turn away from the fight, began, O sire, to tremble, along with their elephants, and foot-soldiers, and cavalry, and cars. Ground then by the Pandavas desirous of victory, those warriors of thy army, struck with fear, fled away in all directions, like masses of clouds driven away by the wind. And those mighty car-warriors, viz., the Pandavas, having vanquished the Dhritarashtras, looked resplendent in that battle, O king, like blazing fires. And they uttered loud leonine roars, and blew their conchs, elated with joy. And they beat their drums, large and small, and cymbals and other instruments.
