Mbh 8.53.1b

Some among them seized the massive arms of Keshava, and some among them, O king, seized Partha himself with great joy as he stood on his car. Then Keshava, shaking his arms on the field of battle, threw down all those that had seized them, like a wicked elephant shaking down all the riders from his back. Then Partha, encompassed by those great car-warriors, and beholding his car assailed and Keshava attacked in that manner became filled with rage, and overthrew a large number of car-warriors and foot-soldiers. And he covered all the combatants that were close to him with many arrows, that were fit for close encounters. Addressing Keshava then, he said, "Behold, O Krishna, O thou of mighty arms, these countless samsaptakas engaged in accomplishing a fearful task although slaughtered in thousands. O bull amongst the Yadus, there is none on Earth, save myself, that would be able to bear such a close attack on his car." Having said these words, Vibhatsu blew his conch. Then Krishna also blew his conch filling the welkin with its blare. Hearing that blare the army of the samsaptakas began to waver, O king, and became inspired with great fright. Then that slayer of hostile heroes, viz., the son of Pandu, paralysed the legs of the samsaptakas by repeatedly invoking, O monarch, the weapon called Naga. Thus tied with those foot-tying bands by the high-souled son of Pandu, all of them stood motionless, O king, as if they had been petrified. The son of Pandu then began to slay those motionless warriors like Indra in days of yore slaying the Daityas in the battle with Taraka. Thus slaughtered in that battle, they set the car free, and commenced to throw down all their weapons. Their legs being paralysed, they could not, O king, move a step. Then Partha slew them with his straight arrows. Indeed, all these warriors in that battle, aiming at whom Partha had invoked that foot-tying weapon, had their lower limbs encircled with snakes.
