Mbh 16.3.5a

"'Having said these words, Satyaki rushed at Kritavarma and severed his head with a sword in the very sight of Keshava. Yuyudhana, having achieved this feat, began to strike down others there present. Hrishikesa ran to prevent him from doing further mischief. At that time, however, O monarch, the Bhojas and Andhakas, impelled by the perverseness of the hour that had come upon them, all became as one man and surrounded the son of Sini. Janardana of mighty energy, knowing the character of the hour, stood unmoved without giving way to anger at the sight of those heroes rushing in wrath at Satyaki from every side. Urged by fate and inebriated with drink, they began to strike Yuyudhana with the pots from which they had been eating. When the son of Sini was being thus assaulted, Rukmini's son became highly enraged. He rushed forward for rescuing Satyaki who was engaged with the Bhojas and the Andhakas. Endued with might of arms and wealth of energy, those two heroes exerted themselves with great courage. But as the odds were overwhelming, both of them were slain in the very sight of Krishna. The delighter of the Yadus, beholding his own son, and the son of Sini too, slain, took up, in wrath, a handful of the Eraka grass that grew there. That handful of grass became a terrible bolt of iron endued with the energy of the thunderbolt. With it Krishna slew all those that came before him. Then the Andhakas and the Bhojas, the Saineyas and the Vrishnis, urged by Time, struck one another in that fearful melee. Indeed, O king, whoever amongst them took up in wrath a few blades of the Eraka grass, these, in his hands, became soon converted into a thunderbolt, O puissant one. Every blade of grass there was seen to be converted into a terrible iron bolt. All this, know, O king, was due to the curse denounced by Brahmanas. He who hurled a blade of grass saw that it pierced through even such things as were utterly impenetrable.
