Mbh 6.103.2a

Sanjaya said, “In battle Drona never recognises Partha as dear to himself. Partha also, keeping a Kshatriya’s duty in view, recognises not in battle his preceptor. Kshatriyas, O king, never avoid one another in battle. Without showing any regard for one another, they fight with sires and brothers. In that battle, O Bharata, Partha pierced Drona with three shafts. Drona, however, regarded not those shafts shot in battle from Partha’s bow. Indeed, Partha once more covered the preceptor in the fight with a shower of arrows. Thereupon the latter blazed up with wrath like a conflagration in a deep forest. Then, O king, Drona soon covered Arjuna in that combat with many straight shafts, O Bharata. Then king Duryodhana, O monarch, despatched Susarman for taking up the wing of Drona. Then the ruler of the Trigartas, excited with rage and forcibly drawing his bow, covered Partha, O king, with a profusion of arrows furnished with iron heads. Shot by those two warriors, O king, the shafts looked beautiful in the welkin like cranes in the autumnal sky. Those shafts, O lord, reaching the son of Kunti, entered his body like birds disappearing within a tree bending with a load of tasteful fruits. Arjuna then, that foremost of car-warriors, uttering a loud roar in that battle pierced the ruler of the Trigartas and his son with his shafts. Pierced by Partha like Death himself at the end of the Yuga, they were unwilling to avoid Partha, resolved as they were on laying down their lives. And they shot showers on the car of Arjuna. Arjuna, however, received those arrowy showers with showers of his own, like a mountain, O monarch, receiving a downpour from the clouds. And the lightness of hand that we then beheld of Vibhatsu was exceedingly wonderful. For alone he baffled that unbearable shower of arrows shot by many warriors like the wind alone scattering myriads of clouds rushing upon clouds.
