Mbh 7.160.1a

“Sanjaya said, ‘Then king Yudhishthira, and Bhimasena, the son of Pandu, O monarch, encompassed Drona’s son on all sides. Seeing this, king Duryodhana, aided by Bharadwaja’s son, rushed against the Pandavas in that encounter. Then commenced a battle that was fierce and terrific, enhancing the fears of the timid. Yudhishthira, in wrath began to despatch vast numbers of Amvashthas, Malavas, Vangas, Sivis, and Trigartas, to the domain of the dead. Bhima also, mangling the Abhishahas, the Surasenas, and other Kshatriyas difficult to defeat in battle, made the earth miry with blood. The diadem-decked (Arjuna) of white steeds despatched, O king, the Yaudheyas, the Mountaineers, the Madrakas, and the Malavas also, to the regions of the dead. Forcibly struck with swiftly-coursing shafts, elephants began to fall down on the earth like double-crested hills. Strewn with the lopped-off trunks of elephants that still moved in convulsions, the earth seemed as if covered with moving snakes. Covered with the fallen umbrellas of kings that were adorned with gold, the field of battle looked resplendent like the firmament at the end of the Yuga bespangled with suns, moons and stars. About this time a fierce uproar arose near Drona’s car, in the midst of which could be heard the words, “Slay”, “Strike fearlessly”, “Pierce”, “cut in pieces”. Drona, however, filled with rage, began to destroy by means of the Vayavya weapon the foes about him, like a mighty tempest destroying gathering masses of clouds. Thus treated by Drona, the Panchalas fled away, from fear, in the very sight to Bhimasena and the high-souled Partha. Then the diadem-decked (Arjuna) and Bhimasena soon checked the flight of their troops and accompanied by a large car-force attacked the vast force of Drona. Vibhatsu attacking the right and Vrikodara the left, they both poured on Bharadwaja’s son two dense showers of arrows.
