Mbh 4.58.2a

Vaisampayana continued, “Thus addressed by Arjuna, Virata’s son urged his steeds decked with gold towards the car of Bharadwaja’s son. And Drona also rushed towards the impetuously advancing Partha, the son of Pandu,--that foremost of car-warriors,--like an infuriate elephant rushing towards an infuriate compeer. And the son of Bharadwaja then blew his conch whose blare resembled that of a hundred trumpets. And at that sound the whole army become agitated like the sea in a tempest. And beholding those excellent steeds red in hue mingling in battle with Arjuna’s steeds of swan-like whiteness endued with the speed of the mind, all the spectators were filled with wonder. And seeing on the field of battle those car-warriors--the preceptor Drona and his disciple Partha--both endued with prowess, both invincible, both well-trained, both possessed of great energy and great strength, engaged with each other, that mighty host of the Bharatas began to tremble frequently. And that mighty car-warrior Partha, possessed of great prowess and filled with joy upon reaching Drona’s car on his own, saluted the preceptor. And that slayer of hostile heroes, the mighty armed son of Kunti, then addressed Drona in an humble and sweet tone, saying, ‘Having completed our exile in the woods, we are now desirous of avenging our wrongs. Even invincible in battle, it doth not behove thee to be angry with us. O sinless one, I will not strike thee unless thou strikest me first. Even this is my intention. It behoveth thee to act as thou choosest.’ Thus addressed Drona discharged at him more than twenty arrows. But the light-handed Partha cut them off before they could reach him. And at this, the mighty Drona, displaying his lightness of hand in the use of weapons, covered Partha’s car with a thousand arrows. And desirous of angering Partha, that hero of immeasurable soul, then covered his steeds of silvery whiteness with arrows whetted on stone and winged with the feathers of the Kanka bird.
