Alas, those princes who succeeded in crossing, by boats made by their own excellent weapons, the great Drona-ocean having cars for its deep lakes, arrows for its waves, the ornaments of warriors for its gems, car-horses for its animals, darts and swords for its fishes, elephants for its alligators, bows for its whirlpools, powerful weapons for its foam, and the sign of battle for its moonrise causing it to swell with energy, and the twang of the bow and the sound of palms for its roar,-alas, even those princes have been killed from carelessness.
