tataḥ karṇaḥ prathamaṃ tatra pārthaṃ maheṣubhirdaśabhiḥ paryavidhyat |
tamarjunaḥ pratyavidhyacchitāgraiḥ kakṣāntare daśabhiratīva kruddhaḥ || 12 ||

Then Karna first pierced Partha in that encounter, with ten mighty shafts. Arjuna pierced him in return with ten keen-pointed shafts, shot with great vigour, in the centre of the chest. Indeed, the suta's son and Arjuna then mangled each other with many shafts equipped with goodly wings. Desirous of obtaining advantage of each other's lapses in that dreadful encounter, with cheerful hearts they rushed against each other fiercely.
