Mbh 7.167.1b

Then that prince of the Rakshasas, viz., Alamvusha, O king, riding upon a foremost car, harnessed with eight steeds, having terrible-looking Pisachas of equine faces yoked unto it, furnished with blood-red banners, decked with floral garlands made of black iron, covered with bear-skins, and possessing a tall standard over which perched a terrible, fierce-looking, and incessantly shrieking vulture, of spotted wings and wide-open eyes, proceeded against those advancing heroes. That Rakshasa, O king, looked beautiful like a loose heap of antimony, and he withstood the advancing Arjuna, like Meru withstanding a tempest, scattering showers of arrows, O monarch, upon Arjuna’s head. The battle then that commenced between the Rakshasa and that human warrior, was exceedingly fierce. And it filled all the spectators there, O Bharata, with wonder. And it conduced to the joy also of vultures and crows, of ravens and owls and Kankas and jackals. Arjuna struck Alamvusha with six shafts and then cut off his standard with ten sharp arrows. With a few other arrows, he cut off his driver, and with some others his Trivenu, and with one more, his bow, and with four others his four steeds. Alamvusha strung another bow, but that also Arjuna cut off in two fragments. Then, O bull of Bharata’s race, Partha pierced that prince of the Rakshasas with four keen arrows. Thus pierced, the Rakshasa fled away in fear. Having vanquished him, Arjuna quickly proceeded towards the spot where Drona was, shooting as he went, many shafts, O king, at men, elephants, and steeds. Slaughtered O monarch, by the illustrious son of Pandu, the combatants fell down on the ground, like trees laid low by a tempest. Thus treated by the illustrious son of Pandu, all of them fled like a frightened herd of deer.’”
