6.46.34

sa tvaṃ puruṣaśārdūla vikramya jahi kauravān |
ahaṃ ca tvānuyāsyāmi bhīmaḥ kṛṣṇaśca māriṣa || 34 ||

As Kartikeya, in days of old, was ever the commander of the celestial host, so also art thou, O bull among men, the commander of the Pandava host. Putting forth thy prowess, O tiger among men, slay the Kauravas. I will follow thee, and Bhima, and Krishna also, O sire, and the sons of Madri united together, and the sons of Draupadi accoutred in mail, and all the other foremost of kings, O bull among men. Then gladdening (the listeners) Dhrishtadyumna said, 'Ordained of old by Sambhu himself, I am, O son of Pritha, the slayer of Drona. I shall now fight in battle against Bhishma, and Drona and Kripa and Salya and Jayadratha and all the proud monarchs (on the Kuru side)'. When that foremost of princes, that slayer of foes, the son of Prishata, said this defiantly, the Pandava warriors, endued with great energy and incapable of being defeated in battle, all set up a loud shout. And then Pritha's son Yudhishthira said unto the commander of his army, the son of Prishata, (these words), 'An array known by the name of Krauncharuma, that is destructive of all foes, and that was spoken of by Vrihaspati unto Indra in days of old when the gods and the Asuras fought,--that array destructive of hostile divisions, do thou form. Unseen before, the kings behold it, along with the Kurus.' Thus addressed by that god among men, like Vishnu addressed by the wielder of the thunderbolt, he (Dhrishtadyumna), when morning dawned, placed Dhananjaya in the van of the whole army.
