Mbh 6.47.1c

Then in fierce combat, the mighty Bhishma caused many celestial weapons of great efficacy to appear. And the great grandsire of immeasurable soul then covered Subhadra’s son with thousands of arrows. And at this, ten great bowmen and mighty car-warriors of the Pandavas, quickly rushed on their cars for protecting the son of Subhadra. And those were Virata with his son, and Dhrishtadyumna of Prishata’s race, and Bhima, the five Kekaya brothers, and Satyaki also, O king. And as they were falling upon him with great impetuosity, Bhishma the son of Santanu, in that conflict, pierced the prince of Panchala with three arrows, and Satyaki with ten. And with one winged arrow, whetted and sharp-edged as a razor, and shot from his bow drawn to its fullest stretch, he cut off the standard of Bhimasena. And, O best of men, the standard of Bhimasena, made of gold and bearing the device of a lion, cut off by Bhishma, fell from the car. And Bhima then, piercing Santanu’s son Bhishma in that combat with three arrows, pierced Kripa with one, and Kritavarman with eight. And Uttara also, the son of Virata, on a tusker with upraised trunk, rushed against the ruler of the Madras. Salya, however, succeeded in checking the unparalleled impetuosity of that prince of elephants rushing quickly towards his car. That prince of elephants, in great wrath, placing his leg upon the yoke of (Salya’s) car, killed his four large steeds of excellent speed. The ruler of the Madras then, staying on that car whose steeds had been slain, hurled a dart, all made of iron, and resembling a snake, for slaying Uttara outright. The latter’s coat of mail being cut through by that dart, he became totally deprived of his senses and fell down from his elephant’s neck, with the hook and the lance loosened from his grasp. And Salya then, taking up his sword and jumping down from his excellent car, and putting forth his prowess, cut off the large trunk of that prince of elephants.
