Mbh 6.109.2b

As each day came, Bhishma the son of Santanu, formed arrays in battle, sometimes after the manner of the Asuras, sometimes after that of the Pisachas, and sometimes after that of the Rakshasas. Then commenced the battle between thy troops, O Bharata, and theirs, both parties smiting one another and increasing the population of Yama’s kingdom. And the Parthas with Arjuna at their head, placing Sikhandin in the van, proceeded against Bhishma in that battle, scattering diverse kinds of arrows. And then, O Bharata afflicted by Bhishma with his shafts, (many of) thy warriors, profusely bathed in blood, repaired to the other world. And Nakula and Sahadeva, and the mighty car-warrior Satyaki, approaching thy army, began to afflict it with great vigour. Thus slaughtered in battle, O bull of Bharata’s race, thy warriors were unable to resist that vast host of the Pandavas. Then thy host, vigorously afflicted by great car-warriors and thus slaughtered by them everywhere, fled away on all sides. Slaughtered with sharp shafts by the Pandavas and the Srinjayas they found not a protector, O bull of Bharata’s race.”
