How many people survived the great war in the Mahabharata? Obviously, the Pandavas, Krishna, Ashwaththama, Dhritarashtra, Gandhari and Draupadi come to mind. Are these the only ones?
We shouldn't count Dhṛtarāṣṭra, Draupadi, Gandhari because they didn't participate in the war. They are not survivors of the war as they didn't fight the war.
On the Kaurava side:
On the Pāṇḍava side:
Krishna - We should count him because he is the charioteer of Arjuna and participated in the war.
Aśvatthāma and Kṛpācārya are considered immortals.
So it sums up to 11 people who survived the Kurukshetra war. As said above, Gandhari, Draupadi shouldn't be counted as they didn't take part in the war. Dhṛtarāṣṭra was only listening the narration of the war from Sanjaya.
