Mahabharata Drona Parva Chapter 155:8

Mahabharata Drona Parva (Ghatotkacha-badha Parva) Chapter 155:8 That foremost of victors, viz., Drona's son, having burnt thy foes, shone brilliantly like the blazing Yuga-fire after having burnt all creatures at the end of the Yuga. Then Ghatotkacha, filled with rage, urged that vast Rakshasa force on, saying, Slay the son of Drona!" That command of Ghatotkacha was obeyed by those terrible Rakshasa of bright teeth, large faces, frightful aspects, gaping mouths, long tongues and eyes blazing with wrath. Causing the earth to be filled with their loud leonine roars, and armed with diverse kinds of weapons, they rushed against the son of Drona for slaying him. Endued with fierce prowess, those Rakshasas, with eyes red in wrath, fearlessly hurled at Aswatthaman's head hundreds and thousands of darts, and Sataghnis, and spiked maces, and Asanis and long lances, and axes, and scimitars, and maces, and short arrows and heavy clubs, and battle-axes, and spears, and swords, and lances, and polished Kampanas and Kunapas, and Hulas, and rockets, and stones, and vessels of (hot) treacle, and thunas made of black iron, and mallets, all of terrible forms and capable of destroying foes.

Afflicted with those shafts, that vast force of broad-chested Rakshasas looked like a herd of infuriated elephants afflicted by lions. Then those mighty Rakshasas, thus afflicted by Drona's son, became filled with fury and rushed against the former. The prowess that the son of Drona then showed was exceedingly wonderful, for the feat he achieved is incapable of being achieved by any other being among living creatures, since, alone and unsupported, that warrior acquainted with high and mighty weapons burnt that Rakshasa force with his blazing shafts in the very sight of that prince of Rakshasas. Whilst consuming that Rakshasa force, Drona's son in that battle shone resplendent like the Samvartaka fire, while burning all creatures at the end of the Yuga. Indeed, amongst those thousands of kings and those Pandavas, O Bharata, there was none, except that mighty prince of the Rakshasa, viz., the heroic Ghatotkacha, capable of even looking at the son of Drona in that battle, who was thus employed in consuming their ranks with his shafts, resembling snakes of virulent poison. The Rakshasa, O chief of the Bharatas, with eyes rolling in wrath, striking his palms, and biting his (nether) lip, addressed his own driver, saying, "Bear me towards the son of Drona.
