The Victorious Pandava army and warriors were slaughtered by Ashwathama on the night of the 18th day of the war.

curse imposed by Lord Krishna on the demonic mentality of Aswaddhama.

Aswaddhama kills the Upapandavas, and when he is not done, he uses the brahmastra on the Pandavas, and Arjuna in turn. When the brahmastra is used, Vyasa asks them both to withdraw the brahmastra, averting the possibility of a major deluge.

Arjuna agrees to the Upamshara, but Aswaddhama says that he does not know the Upamshara, to which Vyasa reprimands him and warns him to at least change the direction.Still not forgetting his demonic instincts, Aswaddhama directs the arrow towards Uttara's womb, Abhimanyu's wife. Cursed to live like Jivachavam

He took the Gem from his forehead and cursed him with 3000 years of wandering with a puss filled and diseased body … all lonely with no access to accommodation.

But as per Śiva Mahāpurāṇa this great son of Guru Drōna resides near the river Gaṇgā.
