Mahabharata Drona Parva Chapter 20:2

Mahabharata Drona Parva (Dronabhisheka Parva) Chapter 20:2 'Dhrishtadyumna said, "O thou of excellent vows, never shalt thou be placed under the power of Drona, however much may he strive. Even I shall check Drona today with all his followers. As long as I am alive, O thou of Kuru's race, it behoveth thee not to feel any anxiety. Under no circumstances will Drona be able to vanquish me in battle. Sanjaya continued, 'Having said these words, the mighty son of Drupada owning steeds of the hue of pigeons, scattering his shafts, rushed himself at Drona. Beholding that (to him) evil omen in the form of Dhrishtadyumna stationed before him, Drona soon became exceedingly cheerless. Beholding this, that crusher of foes, viz., thy son Durmukha, desirous of doing what was agreeable to Drona, began to resist Dhrishtadyumna. Then a terrible and a fierce battle took place, O Bharata, between the brave son of Prishata and thy son, Durmukha. Then Prishata's son, quickly covering Durmukha, with a shower of arrows, checked Bharadwaja's son also with a thick arrowy downpour. Beholding Drona checked, thy son Durmukha quickly rushed at Prishata's son and confounded him with clouds of arrows of diverse kinds. And while the prince of the Panchalas and that foremost one of Kuru's race were thus engaged in battle, Drona consumed many sections of Yudhishthira's host. As a mass of clouds is dispersed in different directions by the wind, even so was Yudhishthira's host, in many parts of the field, scattered by Drona. For only a short while did that battle look like an ordinary combat. And then, O king, it became an encounter of infuriated persons in which no consideration was shown for anybody. And the combatants could no longer distinguish their own men from the foe. And the battle raged on, the warriors being guided by inferences and watch-words. Upon the gems on their headgears, upon their necklaces and other ornaments, and upon their coats of mail, rays of light like those of the Sun seemed to fall and play. And cars and elephants and steeds, decked with streaming banners, seemed in that battle to resemble masses of clouds with flocks of cranes under them. And men slew men, and steeds of fiery metal slew steeds, and car-warriors slew car-warriors and elephants slew elephants. And soon a fierce and terrible encounter took place between elephants with tall standards on their backs and mighty compeers (rushing against them). All in consequence of those huge creatures rubbing their bodies against those of hostile compeers and tearing one another (with their tusks), fires mixed with smoke were generated there by (such) friction of countless tusks with tusks. Shorn of the standards (on their backs), those elephants, in consequence of the fires caused by their tusks, looked like masses of clouds in the welkin charged with lightning.
