Mahabharata Udyoga Parva Chapter 151:3

Mahabharata Udyoga Parva (Bhagwat Yana Parva) Chapter 151:3 Yudhishthira said, 'O sire, the strength and weakness, might and feebleness, of everything in the universe, and the intentions of every person here, are well-known to virtuous Kesava. Skilled or unskilled in weapons, old or young, let him be the leader of my forces, who may be indicated by Krishna of Dasarha's race. Even he is the root of our success or defeat. In him are our lives, our kingdom, our prosperity and adversity, our happiness and misery. Even he is the Ordainer and Creator. In him is established the fruition of our desires. Let him, therefore, be the leader of our host, who may be named by Krishna. Let that foremost of speakers say, for the night approacheth. Having selected our leader, worshipped our weapons with offerings of flowers and perfumes, we will, at day-break, under Krishna's orders march to the field of battle! Vaisampayana continued, "Hearing these words of the intelligent king, Yudhishthira the Just, the lotus-eyed Krishna said, eyeing Dhananjaya, the while, 'O king, I fully approve of all those powerful warriors whom ye have named for becoming the leaders of thy troops. All of them are competent to withstand thy foes. Indeed, they can frighten Indra himself in great battle, let alone the covetous and wicked-minded sons of Dhritarashtra. O thou of mighty arms, for thy good I made great efforts to prevent the battle by bringing about peace. By that we have been freed from the debt we owed to virtue. Fault-finding persons will not be able to reproach us for anything. Foolish Duryodhana, destitute of understanding, regardeth himself as skilled in weapons, and though really weak thinketh himself to be possessed of strength. Array thy troops soon, for slaughter is the only means by which they can be made to yield to our demands. Indeed, the sons of Dhritarashtra will never be able to keep their ground when they will behold Dhananjaya with Yuyudhana as his second, and Abhimanyu, and the five sons of Draupadi, and Virata, and Drupada, and the other kings of fierce prowess,—all lords of Akshauhinis. Our army is possessed of great strength, and is invincible and incapable of being withstood. Without doubt, it will slay the Dhartarashtra host. As regards our leader, I would name that chastiser of foes, Dhrishtadyumna.
