Mbh 6.117.6b

Filling in that dreadful battle all the points of the compass, cardinal and subsidiary, with his leonine shouts, Bhishma felled many car-warriors, O king, (from their cars) and many steeds along with their riders. And he caused large bodies of cars to look like forests of palmyras shorn of their leafy heads. That foremost of all wielders of weapons, in that battle, deprived cars and steeds and elephants, of their riders. Hearing the twang of his bow and the slap of his palms, both resembling the roll of the thunder, the troops, O king, trembled all over the field. The shafts, O chief of men, of thy sire were never bootless as they fell. Indeed, shot from Bhishma’s bow they never fell only touching the bodies of the foe (but pierced them through in every case). We saw crowds of cars, O king, deprived of riders, but unto which were yoked fleet steeds, dragged on all sides with the speed of the wind. Full fourteen thousand great car-warriors of noble parentage, prepared to lay down their lives, unretreating and brave, and possessed of standards decked with gold, belonging to the Chedis, the Kasis, and the Karushas, approaching Bhishma, that hero who resembled the Destroyer himself with wide-open mouth, were despatched to the other world, with their steeds, cars and elephants. There was not, O king, a single great car-warrior among the Somakas, who, having approached Bhishma in that battle, returned with life from that engagement. Beholding Bhishma’s prowess, people regarded all those warriors (who approached him) as already despatched to the abode of the king of the Dead. Indeed, no car-warrior ventured to approach Bhishma in battle, except the heroic Arjuna having white steeds (yoked unto his car) and owning Krishna for his charioteer, and Sikhandin, the prince of Panchala, of immeasurable energy.”
