Mahabharata Shalya Parva Chapter 3:2

Mahabharata Shalya Parva Chapter 3:2 The dust, however, that was then raised enveloped the scene, in consequence of which we could not see anything. Darkness also spread over the scene, and the field of battle was covered with arrows. Thy troops, O monarch, then fled away in fear on all sides. When his army was thus broken, the Kuru king, O monarch, rushed against both friends and foes. Then Duryodhana challenged all the Pandavas to battle, O chief of Bharata's race, like the Asura Vali in days of yore challenging all the celestials. The Pandavas then, uniting together and filled with rage, upbraiding him repeatedly and shooting diverse weapons, rushed against the roaring Duryodhana. The latter, however, fearlessly smote his foes with shafts. The prowess that we then saw of thy son was exceedingly wonderful, since all the Pandavas together were unable to transgress him. At this time Duryodhana beheld, staying at a little distance from him, his troops, exceedingly mangled with shafts, and prepared to fly away. Rallying them then, O monarch, thy son, resolved on battle and desirous of gladdening them, addressed those warriors, saying, "I do not see that spot on plain or mountain whither, if you fly, the Pandavas will not slay you. What is the use then in flight? The Pandava army hath now been reduced to a small remnant. The two Krishnas have been exceedingly mangled. If all of us make a stand here, we are certain to have victory. If, however, you fly away, breaking your array, the Pandavas, pursuing your sinful selves, will slay all of you. Death in battle, therefore, is for our good. Death in the field of battle while engaged in fight according to Kshatriya practices is pleasant. Such death produces no kind of grief. By encountering such a death, a person enjoys eternal happiness in the other world. Let all the Kshatriyas assembled here listen to me. It were better that they should even submit to the power of the angry Bhimasena than that they should abandon the duties practised by them from the days of their ancestors. There is no act more sinful for a Kshatriya than flight from battle. You Kauravas, there is not a better path to heaven than the duty of battle. The warrior acquires in a day regions of bliss (in the other world) that take many long years for others to acquire." Fulfilling those words of the king, the great Kshatriya car-warriors once more rushed against the Pandavas, unable to endure their defeat and firmly resolved to put forth their prowess. Then commenced a battle once more, that was exceedingly fierce, between thy troops and the enemy, and that resembled the one between the gods and the Asuras. Thy son Duryodhana then, O monarch, with all his troops, rushed against the Pandavas headed by Yudhishthira.'"
