8.44.35

nakulastu tataḥ kruddho vṛṣasenaṃ smayanniva |
nārācena sutīkṣṇena vivyādha hṛdaye dṛḍham || 35 ||

"'Vrishasena, staying by the side of his father, having pierced Nakula with five arrows made wholly of iron, pierced him once again with three other arrows. The heroic Nakula then, as if smiling, deeply pierced Vrishasena in the chest with a cloth-yard shaft of great keenness. Thus pierced by his mighty foe, that scorcher of foes, viz., Vrishasena, pierced his assailant with twenty arrows and was himself pierced by him with five. Then those two bulls among men shrouded each other with thousands of arrows, at which the divisions that supported them broke. Beholding the troops of Dhritarashtra's son flying away, the Suta's son, following them, O king, began to forcibly stop them. After Karna had gone away, Nakula proceeded against the Kauravas. Karna's son also, avoiding Nakula, proceeded quickly, O sire, to where his father, the son of Radha, was for protecting his car-wheel.
