Ashwathama, in order to avenge his father's as well as other Kuru warriors' deceitful killing by the Pandavas, attacks their camp at night with Kripacharya and Kritavarma. Ashwathama killed Dhrishtadyumna, Shikhandi, Upapandavas, and the remaining Pandava and Panchala army.[33] In the morning, Yudhishthira hears the news and asks Nakula to bring Draupadi from Matsya Kingdom.[57] Draupadi vows that if the Pandavas do not kill Ashwatthama, she would fast to death.[58][59] The Pandavas find Ashwatthama at Vyasa's hut. Arjuna and Ashwatthama end up firing the Brahmashirsha astra at each other. Vyasa intervenes and asks the two warriors to withdraw the destructive weapon. Not endowed with the knowledge to do so, Ashwatthama instead redirects the weapon to Uttara's womb, but Krishna protected the Pandavas' only heir with his Sudarshana Chakra. Krishna curses him for this act. Ashwatthama is caught by the Pandavas and his jewel is taken away.[58] Draupadi gives the jewel to Yudhishthira and forgives the killer of her children. Due to the power of meditation, her wrath is subdued and she lets go of Ashwathama, son of their preceptor Drona saying, "I desired to only pay off our debt for the injury we have sustained. The preceptor's son is worthy of my reverence as the preceptor himself. Let the king bind this gem on his head, O Bharata!"[60]
