Mbh 6.120.1a

Sanjaya said, “Thus all the Pandavas, placing Sikhandin before them pierced Bhishma in that battle repeatedly surrounding him on all sides. And all the Srinjayas, uniting together, struck him with dreadful Sataghnis, and spiked maces, and battle-axes, and mallets, and short thick clubs, and bearded darts, and other missiles, and arrows furnished with golden wing, and darts and lances and kampanas; and with long shafts, and arrows furnished with heads shaped like the calf-tooth, and rockets. Thus afflicted by many, his coat of mail was pierced everywhere. But though pierced in every vital part, Bhishma felt no pain. On the other hand, he then seemed to his enemies to resemble in appearance the (all-destructive) fire that rises at the end of Yuga. His bow and arrows constituted the blazing flames (of that fire). The flight of his weapons constituted its (friendly) breeze. The rattle of his car-wheels constituted its heat and mighty weapons constituted its splendour. His beautiful bow formed its fierce tongue, and the bodies of heroic warriors, its profuse fuel. And Bhishma was seen to roll through the midst of crowds of cars belonging to those kings, or to come out (of the press) at times, or course once more through their midst. Then, disregarding the king of the Panchalas and Dhrishtaketu, he penetrated, O monarch, into the midst of the Pandava army. He then pierced the six Pandava warriors, viz., Satyaki, and Bhima, and Dhananjaya the son of Pandu, and Drupada, and Virata, and Dhrishtadyumna of Prishata’s race, with many excellent arrows of great sharpness and dreadful whizz and exceeding impetuosity, and capable of piercing through every kind of armour. Those mighty car-warriors, however, checking those keen shafts, afflicted Bhishma with great force, each of them striking him with ten shafts. Those mighty shafts, whetted on stone and furnished with golden wings, which the great car-warrior Sikhandin shot, quickly penetrated into Bhishma’s body.
