Mbh 7.201.7a

“Sanjaya said, ‘Upon the fall of the youthful prince of the Chedis, of Vrihatkshatra of Puru’s race, and of Sudarsana, the chief of the Malavas, who was well-accomplished in the science of arms, and upon the defeat of Dhrishtadyumna and Satyaki and Bhima, and feeling great pain and touched to the quick by those words of Yudhishthira, and remembering all his former woes, O lord, Vibhatsu, in consequence of his grief, felt such wrath rise within him the like of which he had never experienced before. It was for this that like a vulgar person, he addressed the preceptor’s son who was worthy of every respect, in such unworthy, indecent, bitter, and harsh language. Addressed, from wrath, in such harsh and cruel words by Partha, O king, Drona’s son, that foremost of all mighty bowmen, became highly angry with Partha and especially with Krishna. The valiant Aswatthaman, then, staying resolutely on his car, touched water and invoked the Agneya weapon incapable of being resisted by the very gods. Aiming at all his visible and invisible foes, the preceptor’s son, that slayer of hostile heroes, inspired with mantras a blazing shaft possessed of the effulgence of a smokeless fire, and let it off on all sides, filled with rage. Dense showers of arrows then issued from it in the welkin. Endued with fiery flames, those arrows encompassed Partha on all sides. Meteors flashed down from the firmament. A thick gloom suddenly shrouded the (Pandava) host. All the points of the compass also were enveloped by that darkness. Rakshasas and Pisachas, crowding together, uttered fierce cries. Inauspicious winds began to blow. The sun himself no longer gave any heat. Ravens fiercely croaked on all sides. Clouds roared in the welkin, showering blood. Birds and beasts and kine, and Munis of high vows and souls under complete control, became exceedingly uneasy. The very elements seemed to be perturbed. The sun seemed to turn. The universe, scorched with heat, seemed to be in a fever.
