Mbh 14.60.3a

"'Vasudeva said, "The feats were highly wonderful that were achieved by those high-souled Kshatriyas. In consequence of their large number, they are incapable of being enumerated in even hundreds of years. I shall however, mention only the foremost of them. Do thou listen, therefore, to me as I mention in brief those feats achieved by the kings of Earth, O thou of godlike splendour. Bhishma of Kuru's race became the generalissimo, having eleven divisions of the Kaurava princes under his command, like Vasava of the celestial forces.[176] Sikhandin of great intelligence, protected by the blessed Arjuna, became the leader of the seven divisions of the sons of Pandu. The battle between the Kurus and the Pandavas (under these leaders) raged for ten days. It was so fierce as to make one's hair stand on its end. Then Sikhandin, in great battle, aided by the wielder of Gandiva, slew, with innumerable arrows, the son of Ganga fighting bravely. Lying on a bed of arrows, Bhishma waited like an ascetic till the sun leaving his southward path entered on his northerly course when that hero gave up his life-breaths. Then Drona, that foremost of all persons conversant with arms, that greatest of men under Duryodhana, like Kavya himself of the lord of the Daityas, became generalissimo.[177] That foremost of regenerate persons, ever boasting of his prowess in battle, was supported by the remnant of the Kaurava force consisting then of nine Akshauhinis, and protected by Kripa and Vrisha and others. Dhrishtadyumna conversant with many mighty weapons, and possessed of great intelligence, became the leader of the Pandavas. He was protected by Bhima like Varuna protected by Mitra. That high-souled hero, always desirous of measuring his strength with Drona, supported by the (remnant of the) Pandava army, and recollecting the wrongs inflicted (by Drona) on his sire (Drupada, the king of the Panchalas), achieved great feats in battle.
