Mahabharata Drona Parva Chapter 159:3

Mahabharata Drona Parva (Ghatotkacha-badha Parva) Chapter 159:3 Sighing (in rage) like a snake, the preceptor's son, then, covered Dhrishtadyumna in that battle (with a shower of arrows). The mighty-armed son of Prishata, however, that best of car-warriors, surrounded by all the Panchala troops, though thus struck with arrows in that encounter by Drona's son, did not tremble, relying as he did on his own energy. In return, he sped many arrows at Aswatthaman. Both engaged in a gambling match in which the stake was life itself, those heroes, unable to brook each other, resisted each other and checked each other's arrowy showers. And those great bowmen shot dense showers of shafts all around. Beholding that fierce battle, inspiring terror, between Drona's and Prishata's son, the Siddhas and Charanas and other sky-ranging beings applauded them highly. Filling the welkin and all the points of the compass with clouds of shafts, and creating a thick gloom therewith, those two warriors continued to fight with each other, unseen (by any of us). As if dancing in that battle, with their bows drawn to circles, resolutely aspiring to slay each other, those mighty-armed warriors, inspiring fear in every heart, fought wonderfully and with remarkable activity and skill. Applauded by thousands of foremost warriors in that battle, and thus resolutely engaged in fight like two wild elephants in the forest, both the armies, beholding them, became filled with delight. And leonine shouts were heard there, and all the combatants blew their conchs. And hundreds and thousands of musical instruments began to be sounded. That fierce fight, enhancing the terror of the timid, seemed only for a short time to be waged equally. Then Drona's son, O king, making a rush, cut off the bow, and standard, and umbrella, and the two Parshni drivers, and the principal driver, and the four steeds, of the high-souled son of Prishata. And that warrior of immeasurable soul then caused the Panchalas in hundreds and thousands, by means of his straight shafts, to fly away. Beholding those feats of Drona's son, resembling those of Vasava himself in battle, the Pandava host, O bull of Bharata race, began to tremble in fear. Slaying a hundred Panchalas with a hundred arrows, and three foremost of men with three keen arrows, in the very sight of Drupada's son and of Phalguna, that mighty car-warrior, viz., the son of Drona, slew a very large number of Panchalas that stayed before him. The Panchalas then, as also the Srinjayas, thus disconcerted in battle, fled away leaving Drona's son, with their banners torn. Then that mighty car-warrior, viz., the son of Drona, having vanquished his foes in battle, uttered a loud roar like that of a mass of clouds at the end of summer. Having slain a large number of foes, Aswatthaman looked resplendent like the blazing fire at the end of the Yuga, after having consumed all creatures. Applauded by all the Kauravas after having defeated thousands of foes in battle, the valiant son of Drona beamed forth in beauty, like the chief of the celestials himself after vanquishing his foes.
