"Sanjaya said, 'After the (Kuru) army had been rallied, Shalva, the ruler of the Mlecchas, filled with rage, rushed against the large force of the Pandavas, riding on a gigantic elephant, with secretions issuing from the usual limbs, looking like a hill, swelling with pride, resembling Airavata himself, and capable of crushing large bands of foes. Shalva's animal sprung from a high and noble breed. It was always worshipped by Dhritarashtra's son. It was properly equipped and properly trained for battle, O king, by persons well-conversant with elephant-lore. Riding on that elephant, that foremost of kings looked like the morning sun at the close of summer. Mounting on that foremost of elephants, O monarch, he proceeded against the Pandavas and began to pierce them on all sides with keen and terrible shafts that resembled Indra's thunder in force. While he shot his arrows in that battle and despatched hostile warriors to Yama's abode, neither the Kauravas nor the Pandavas could notice any lapses in him, even as the Daityas, O king, could not notice any in Vasava, the wielder of the thunder, in days of yore, while the latter was employed in crushing their divisions. The Pandavas, the Somakas, and the Srinjayas, beheld that elephant looking like a 1,000 elephants careering around them, even as the foes of the gods had in days of yore beheld the elephant of Indra in battle. Agitated (by that animal), the hostile army looked on every side as if deprived of life.
