Mbh 7.9.1a

“Dhritarashtra said, ‘How did the Pandavas and the Srinjayas slay Drona in battle,--Drona, who was so accomplished in weapons amongst all wielders of arms? Did his car break (in course of the fight)? Did his bow break while he was striking (the foe)? Or, was Drona carless at the time when he met with his death-blow? How, indeed, O child, could Prishata’s son, (viz., Dhrishtadyumna) the prince of the Panchalas, slay that hero incapable of being humiliated by enemies, who scattered thick showers of shafts furnished with wings of gold, and who was endued with great lightness of hand, that foremost of Brahmanas, who was accomplished in everything, acquainted with all modes of warfare, capable of shooting his shafts to a great distance, and self-restrained, who was possessed of great skill in the use of weapons and armed with celestial weapons, that mighty warrior, of unfading glory, who was always careful, and who achieved the fiercest feats in battle? It is plain, it seems to me, that destiny is superior to exertion, since even brave Drona hath been slain by the high-souled son of Prishata, that hero in whom were the four kinds of weapons. Alas, thou sayest that that Drona, that preceptor in bowmanship, is slain. Hearing of the slaughter of that hero who used to ride his bright car covered with tiger skins and adorned with pure gold. I cannot drive away my grief. Without doubt, O Sanjaya, no one dies of grief caused by another’s calamity, since, wretch that I am, I am yet alive although I have heard of Drona’s death. Destiny I regard to be all powerful, exertion is fruitless. Surely, my heart, hard as it is, is made of adamant, since it breaketh not into a hundred pieces, although I have heard of Drona’s death. He who was waited upon by Brahmanas and princes desirous of instruction in the Vedas and divination and bowmanship, alas, how could he be taken away by Death?
