Mbh 6.63.1b

And dragging car-warriors down from their cars, and warriors fighting from the backs of heroes, and foot soldiers as they stood on the ground, in the army of thy son, the mighty-armed Bhimasena slew them all with his mace like the wind crushing trees by its force. And that mace of his, slaying elephants and steeds, became smeared with fat, marrow, flesh, and blood, and looked exceedingly terrible. And with the bodies of slain men and cavalry lying scattered about, the field of battle wore the appearance of the abode of Yama. And the terrible and slaughtering mace of Bhimasena, resembling the fierce bludgeon of Death and endued with the effulgence of Indra’s bolt, looked like Pinaka of the angry Rudra while destroying living creatures. Indeed, that mace of the high-souled son of Kunti, who was slaying all around, looked fiercely resplendent like the bludgeon of the Destroyer himself at the time of the universal dissolution. And beholding him thus routing that large army repeatedly and advancing like Death’s self, all the warriors became cheerless. Withersoever the son of Pandu, raising his mace, cast his eyes, in consequence of his look alone, O Bharata, all the troops there seemed to melt away. Beholding Vrikodara of terrible deeds, thus routing the army and unvanquished by even so large a force and devouring the (hostile) division like the Destroyer himself with wide-open mouth, Bhimasena speedily came towards him, on his car of solar effulgence and rattle loud as that of the clouds, (shrouding the welkin) with his arrowy showers like a vapoury canopy charged with rain. Then the mighty-armed Bhimasena, beholding Bhishma thus advancing like the Destroyer himself with wide-open mouth, rushed towards him, excited with wrath. At that moment, that foremost hero of Sini’s race viz., Satyaki of sure aim, fell upon the grandsire, slaying his enemies (along the way) with his firm bow and causing thy son’s army to tremble.
