Mbh 1.230.2c

Sometimes piercing hundred creatures with one shaft and sometimes a single creature with hundred shafts, Arjuna moved about in his car. The creatures themselves, deprived of life, began to fall into the mouth of Agni (god of fire), struck down as it were by death itself. On the banks of rivers or on uneven plains or on crematoriums, go where they did, the creatures (dwelling in Khandava) found no ease, for wherever they sought shelter there they were afflicted by the heat. And hosts of creatures roared in pain, and elephants and deer and wolves set up cries of affliction. At that sound the fishes of the Ganges and the sea, and the various tribes of Vidyadharas dwelling in that forest all became frightened. O thou of mighty arms, let alone battling with them, no one, could even gaze at Arjuna and Janardana of dark hue. Hari slew with his discus those Rakshasas and Danavas and Nagas that rushed at him in bands. Of huge bodies, their heads and trunks were cut off by the swift motion of the discus, and deprived of life they fell down into the blazing fire. Gratified with large quantities of flesh, blood, and fat, the flames rose up to a great height without a curling wreath of smoke. Hutasana (fire-god) with blazing and coppery eyes, and flaming tongue and large mouth, and the hair on the crown of his head all fiery, drinking, with the help of Krishna and Arjuna, that nectar-like stream of animal fat, became filled with joy. Gratified greatly, Agni derived much happiness.
