Enraged, Ashwatthama unleashed the Narayanastra, a weapon gifted to him by his father, on the Pandava army. Krishna tells the Pandavas and their warriors to drop their weapons and lie down on the ground so that they all surrender completely to the power of this weapon. Though some like Bhima resist, Krishna and the others manage to restrain or pacify the dissenters, and the weapon is rendered ineffective. According to the Chaturdhar compilation, the Narayana Astra destroyed one Akshauhini of Pandava army completely. After the use of Narayana Astra, a terrible war between both armies took place. Ashwatthama defeated Dhrishtadyumna in direct combat, but failed to kill him as Satyaki and Bhima covered his retreat. Terrible war took place between the warriors of both sides as Ashwatthama forced both Satyaki and Bhima to withdraw. In his fury, Ashwatthama manages to kill King Nila of Mahismati.
