Karna Parva 84.24

Nakula distressed with arrows (from Vrishasena), in return, also struck his enemy and Vrishasena being thus struck by Nakula became very angry but the noble Nakula being protected by his brother Bhimasena at that time in that hard fight performed prodigies of valour. Then the son of Karna angry at heart, with eighteen arrows, struck the brave Nakula with whom fighting was like play and who was destroying single-handed the bravest warriors, chargers and elephants.
