And the drivers on the backs of many elephants, with their breasts pierced by car-warriors with broad-headed shafts in that battle, fell down, their lances and hooks loosened from their grasp. And some elephants, struck with long shafts, uttered crane like cries and ran in all directions, crushing friends and foes by trampling them to death. And covered with countless bodies of elephants and steeds and car-warriors, the earth, O king, became miry with flesh and blood. And large cars with wheels and many without wheels, crushed by the points of their tusks, were thrown up by elephants, with the warriors mounted on them. Cars were seen deprived of warriors. And riderless steeds and elephants ran in all directions, afflicted with wounds. And there father slew his son, and son slew his sire, for the battle that took place was exceedingly fierce and nothing could be distinguished. Men sank ankle-deep in the gory mire and looked like tall trees whose lower parts were swallowed up in a blazing forest-conflagration. And robes and coats of mail and umbrellas and standards having been dyed with blood, everything seemed to be bloody on the field. Large bodies of slain steeds, of cars, and of men, were again cut into fragments by the rolling of car-wheels. And that sea of troops having elephants for its current, and slain men for its floating moss and weeds, and cars for its fierce, eddies, looked terribly grim.
