Mbh 3.283.1a

“Markandeya said, ‘And while those troops (thus withdrawn) were reposing themselves in their quarters, many little Rakshasas and Pisachas owning Ravana as their leader, penetrated amongst them. And among these were Parvana, Patana, Jambha, Khara, Krodha-vasa, Hari, Praruja, Aruja and Praghasa, and others. And as these wicked ones were penetrating (the monkey host) in their invisible forms, Vibhishana, who had the knowledge thereof, broke the spell of their invisibility. And once seen, O king, by the powerful and long-leaping monkeys, they were all slain and prostrated on the earth, deprived of life. And unable to endure this, Ravana marched out at the head of his troops. And surrounded by his terrible army of Rakshasas and Pisachas, Ravana who was conversant with the rules of warfare like a second Usanas invested the monkey host, having disposed his troops in that array which is named after Usanas himself. And beholding Ravana advancing with his army disposed in that array, Rama, following the mode recommended by Vrihaspati, disposed his troops in counter array for opposing that wanderer of the night. And coming up quickly, Ravana began to fight with Rama. And Lakshmana singled out Indrajit, and Sugriva singled out Virupakshya, and Nikharvata fought with Tara, and Nala with Tunda, and Patusa with Panasa. And each warrior, advancing up to him whom he regarded as his match, began to fight with him on that field of battle, relying on the strength of his own arms, and that encounter, so frightful to timid persons, soon became terrible and fierce like that between the gods and the Asuras in the days of old. And Ravana covered Rama with a shower of darts and lances and swords, and Rama also afflicted Ravana with his whetted arrows of iron furnished with the sharpest points, and in the same way Lakshmana smote the contending Indrajit with arrows capable of penetrating into the most vital parts and Indrajit also smote Sumitra’s son with an arrowy shower.
