Mbh 7.170.1a

“Sanjaya said, ‘In that fierce and terrible battle, Dhrishtadyumna, O king, proceeded against Drona. Holding his formidable bow and repeatedly stretching his bowstring, the Panchala prince rushed towards Drona’s car decked with gold. And as Dhrishtadyumna proceeded for accomplishing the destruction of Drona, the Panchalas and the Pandavas, O king, surrounded him. Beholding Drona, that foremost of preceptors, thus assailed, thy son, resolutely contending in battle, protected Drona on all sides. Then those two oceans of troops encountered each other on that night, looked like two terrible oceans lashed into fury by tempest, with all living creatures within them exceedingly agitated. Then the prince of the Panchalas, O king, quickly pierced Drona in the chest with five arrows and uttered a leonine roar. Drona, however, O Bharata, piercing his foe in return with five and twenty arrows in that battle, cut off, with another broad-headed arrow, his bright bow. Forcibly pierced by Drona, O bull of Bharata’s race, Dhrishtadyumna, quickly casting aside his bow, bit his (nether) lip in rage. Indeed, O monarch, the valiant Dhrishtadyumna, excited with wrath, took up another formidable bow for accomplishing the destruction of Drona. That slayer of hostile heroes, that warrior endued with great beauty, stretching that formidable bow to his ear, shot a terrible shaft capable of taking Drona’s life. That shaft, thus sped by the mighty prince in that fierce and dreadful battle, illumined the whole army like the risen sun. Beholding that terrible shaft, the gods, the Gandharvas, and the Danavas, said these words, O king, viz., “Prosperity to Drona!” Karna, however, O king, displaying great lightness of hand cut off into dozen fragments that shaft as it coursed towards the preceptor’s car. Thus cut off into many fragments, O king, that shaft of Dhrishtadyumna, O sire, quickly fell down on the earth like a snake without poison.
