Mbh 7.7.4a

“‘Then when that mighty car-warrior, viz.. Bharadwaja’s son, proceeded to battle with great speed, the earth seemed to tremble with loud sounds of wailing. Then the thick dust, raised by the wind resembling a canopy of tawny silk, enveloped the sky and the sun. And though the firmament was cloudless, yet a shower fell of pieces of flesh, bones, and blood. And vultures and hawks and cranes and Kankas, and crows in thousands, began continually to fall upon the (Kaurava) troops. And jackals yelled aloud; and many fierce and terrible birds repeatedly wheeled to the left of thy army, from desire of eating flesh and drinking blood,[11] and many blazing meteors, illuminating (the sky), and covering large areas with their tails, fell on the field with loud sound and trembling motion. And the wide disc of the sun, O monarch, seemed to emit flashes of lightning with thundering noise, when commander of the (Kaurava) army set out. These and many other portents, fierce and indicating a destruction of heroes, were seen during the battle. Then commenced the encounter between the troops of the Kurus and the Pandavas, desirous of slaying each other. And so loud was the din that it seemed to fill the whole earth. And the Pandavas and the Kauravas, enraged with each other and skilled in smiting, began to strike each other with sharp weapons, from desire of victory. Then that great bowman of blazing effulgence rushed towards the troops of the Pandavas with great impetuosity, scattering hundreds of sharp arrows. Then the Pandavas and the Srinjayas, beholding Drona rush towards them, received him, O king, with showers upon showers (in distinct sets) of arrows. Agitated and broken by Drona, the large host of the Pandavas and the Panchalas broke like rows of cranes by force of the wind. Invoking into existence many celestial weapons in that battle, Drona, within a very short time, afflicted the Pandavas and the Srinjayas.
