Mbh 9.15.1a

"Sanjaya said, 'Duryodhana, O king, and Dhrishtadyumna, the son of Prishata, fought a fierce battle, using arrows and darts in profusion. Both of them, O monarch, shot showers of arrows like showers of rain poured by the clouds in the rainy season. The (Kuru) king, having pierced with five arrows the slayer of Drona, Prishata's son of fierce shafts, once more pierced him with seven arrows. Endued with great might and steady prowess, Dhrishtadyumna, in that battle, afflicted Duryodhana with seventy arrows. Beholding the king thus afflicted, O bull of Bharata's race, his uterine brothers, accompanied by a large force, encompassed the son of Prishata. Surrounded by those Atirathas on every side, the Pancala hero, O king, careered in that battle, displaying his quickness in the use of weapons. Shikhandi, supported by the Prabhadrakas, fought with two Kuru bowmen, Kritavarma and the great car-warrior Kripa. Then also, O monarch, that battle became fierce and awful since the warriors were all resolved to lay down their lives and since all of them fought, making life the stake. Shalya, shooting showers of shafts on all sides, afflicted the Pandavas with Satyaki and Vrikodara amongst them. With patience and great strength, O monarch, the king of the Madras at the same time fought with the twins (Nakula and Sahadeva), each of whom resembled the Destroyer himself in prowess. The great car-warriors among the Pandavas who were mangled in that great battle with the shafts of Shalya, failed to find a protector. Then the heroic Nakula, the son of Madri, seeing king Yudhishthira the just greatly afflicted, rushed with speed against his maternal uncle. Shrouding Shalya in that battle (with many arrows), Nakula, that slayer of hostile heroes, smiling the while, pierced him in the centre of the chest with ten arrows, made entirely of iron, polished by the hands of the smith, equipped with wings of gold, whetted on stone, and propelled from his bow with great force.
