Mbh 8.1.2a

Vaishampayana said, "After Drona had been slain, O monarch, the royal warriors (of the Kaurava army) headed by Duryodhana, with hearts filled with great anxiety, all repaired to Drona's son. Lamenting the loss of Drona, and deprived of energy in consequence of their cheerlessness, they sat around the son of Sharadvata's daughter, afflicted with grief. Comforted for a little while by considerations founded upon the scriptures, when night came, those rulers of Earth proceeded to their respective tents. Those lords of Earth, however, O thou of Kuru's race, could feel no happiness in their abodes. Thinking of that immense slaughter, they could not also sleep. The Suta's son (Karna), and king Suyodhana and Duhshasana and Shakuni, in special, could not compose themselves to sleep. Those four passed that night together in Duryodhana's tent, reflecting upon the woes they had inflicted upon the high-souled Pandavas. Formerly they had brought Draupadi, plunged into woe on account of the match at dice, into the assembly. Recollecting it they experienced great regret, their hearts being filled with anxiety. Thinking of those sufferings inflicted (upon the Pandavas) in consequence of the gambling match they passed that night in sorrow, O king, as if it were really a hundred years. Then when morning came, observing the dictates of the ordinance, all of them duly went through the customary rites. Having gone through these customary rites, and comforted to some extent, O Bharata, they ordered their troops to be arrayed, and then came out for battle, having made Karna their generalissimo by tying the auspicious thread round his wrists, and having caused many foremost of Brahmanas, by presents of vessels of curds, clarified butter, akshatas, coins of gold, kine, jewels and gems, and costly robes, to pray for their victory, and having caused heralds and musicians, and panegyrists to adore them with hymns about victory.
