tadantaramameyātmā kaunteyaḥ śvetavāhanaḥ |
abhyadravadraṇe kruddho droṇaṃ prati mahārathaḥ || 56 ||

Desirous, O king, of rescuing, his son who was afflicted by the Vrishni hero, Drona, in that great battle, pierced the latter with a shaft of exceeding sharpness. Satyaki then, abandoning the mighty car-warrior Aswatthaman, pierced Drona himself in that battle with twenty arrows of exceeding sharpness. Soon after, that scorcher of foes and mighty car-warrior, viz., Kunti's son of immeasurable soul, excited with wrath, rushed in that battle against Drona. Then Drona and Partha encountered each other in fierce combat like the planets Budha and Sukra, [paragraph continues] O king, in the firmament.
