Mbh 7.176.1

“Sanjaya said, ‘During the progress of that battle between Karna and the Rakshasa, the valiant Alayudha, that prince of Rakshasa, appeared (on the field). Accompanied by a large force, he approached Duryodhana. Indeed, surrounded by many thousands of frightful Rakshasas of diverse forms and endued with great heroism, he appeared (on the field) recollecting his old quarrel (with the Pandavas). His kinsmen, that valiant Vaka, who ate Brahmanas, as also Kirmira of great energy, and his friend Hidimva, had been slain (by Bhima). He had waited for a long time, brooding over his old quarrel. Learning now that a nocturnal battle was raging, he came, impelled by the desire of slaying Bhima in fight, like an infuriated elephant or an angry snake. Desirous of battle, he addressed Duryodhana and said, “It is known to thee, how my kinsmen, the Rakshasa Vaka and Kirmira and Hidimva have been slain by Bhima. What shall I say more, the virgin Hidimva was formerly deflowered by him, disregarding us and the other Rakshasas. I am here, O king, to slay that Bhima with all his followers, steeds, cars, and elephants, as also that son of Hidimva with friends. Slaying today all the sons of Kunti, Vasudeva and others that walk before them, I will devour them with all their followers. Command all thy troops to desist from battle. We will fight with the Pandavas.”
