Mbh 7.30.1a

“Sanjaya said, ‘Vrikodara, however, could not brook that slaughter of his army. He struck Valhika with sixty and Karna with ten arrows. Drona then, desirous of slaying Bhima, quickly struck the latter, in his very vitals, many straight and whetted shafts of keen edge. Desirous again of allowing no time, he once more struck him with six and twenty shafts whose touch resembled that of fire and which were all like snakes of virulent poison. Then Karna pierced him with a dozen shafts, and Aswatthaman with seven, and king Duryodhana also with six. The mighty Bhimasena, in return, pierced them all. He struck Drona with fifty shafts, and Karna with ten. And piercing Duryodhana with a dozen shafts, and Drona with eight, he engaged in that battle uttering a loud shout. In that encounter in which the warriors fought reckless of their lives and in which death was easy of attainment, Ajatasatru despatched many warriors, urging them to rescue Bhima. Those heroes of immeasurable energy, viz., the two sons of Madri and Pandu, and others headed by Yuyudhana, quickly proceeded to Bhimasena’s side. And those bulls among men, filled with rage and uniting together, advanced to battle, desirous of breaking the army of Drona that was protected by many foremost of bowmen. Indeed, those great car-warriors of mighty energy, viz., Bhima and others, fell furiously upon Drona’s host. Drona, however, that foremost of car-warriors, received without any anxiety, all those mighty car-warriors, of great strength,--those heroes accomplished in battle. Disregarding their kingdoms and casting off all fear of death, the warriors of thy army proceeded against the Pandavas. Horsemen encountered horsemen, and car-warriors encountered car-warriors. The battle proceeded, darts against darts, swords against swords, axes against axes. A fierce encounter with swords took place, producing a terrible carnage. And in consequence of the collision of elephants against elephants the battle became furious.
