Mahabharata Bhishma Parva Chapter 59:2

Mahabharata Bhishma Parva (Bhagavat-Gita Parva) Chapter 59:2 And displaying his extreme lightness of hands, and dancing (as it were) along the track of his car, he seemed, O king, to be present everywhere like a circle of fire. And in consequence of the lightness of his movements, the Pandavas in that battle, along with the Srinjayas, beheld that hero, though really alone, as multiplied a thousand-fold. And every one there regarded Bhishma as having multiplied his self by illusion. Having seen him now on the east, the next moment they saw him on the west. And so having seen him on the north, the next moment they saw him on the south. And the son of Ganga was thus seen fighting in that battle. And there was no one amongst the Pandavas capable of even looking at him. What they all saw were only the innumerable shafts shot from his bow. And heroic warriors, beholding him achieve such feats in battle, and (thus) slaughtering their ranks, uttered many lamentations. And, kings in thousands came in contact with thy sire, thus coursing over the field in a superhuman way, and fell upon that fire represented by the enraged Bhishma like flights of senseless insects (upon a blazing fire) for their own destruction. Not a single shaft of that light-handed warrior was futile, falling upon the bodies of men, elephants, and steeds, in consequence of the numbers (opposed to him). With a single straight shaft shot in that battle, he despatched a single elephant like hill riven by the thunderbolt. Two or three elephant-riders at a time, cased in mail and standing together, thy sire pierced with one shaft of sharp point. Whoever approached Bhishma, that tiger among men, in battle, seen for a moment, was next beheld to fall down on the ground. And that vast host of king Yudhishthira the just, thus slaughtered by Bhishma of incomparable prowess, gave way in a thousand directions. And afflicted with that arrowy shower, the vast army began to tremble in the very presence of Vasudeva and the high-souled Partha. And although the heroic leaders of the Pandava army made great efforts, yet they could not check the flight of (even) the great car-warriors of their side afflicted with the shafts of Bhishma. The prowess, in consequence of which that vast army was routed, was equal to that of the chief of the gods himself. And that army was so completely routed, O great king, that no two persons could be seen together. And cars and elephants and steeds were pierced all over, and standards and shafts of cars were strewn over the field. And the army of the sons of Pandu uttered cries of oh and alas, and became deprived of senses. And the sire struck the son and the son struck the sire; and friend challenged the dearest of friends to battle as if under the influence of fate. And others amongst the combatants of Pandu's son were seen, O Bharata, to run away, throwing aside their coats of mail, and with dishevelled hair.
