Order of their birth
had five sons. Their order of birth was not same as that of their fathers, as there is a slight change - 1. Prativindhya- Yudhishthira and Draupadi's son 2. Sutasoma - Bhima and Draupadi's son 3. Shatanika - Nakula and Draupadi's son 4. Shrutasena - Sahadeva and Draupadi's son 5. Shrutakarma - Arjuna and Draupadi's son This is because, the first 4 children of Draupadi were born during the 12 year-exile of Arjuna, so, after begotting sons from the first 2 brothers, it is Nakula's turn to enter Draupadi's chambers in Arjuna's absence, and after him, comes Sahadeva. After Arjuna returns from his exile, he fathers his son Shrutakarma, from Draupadi.
Death
On the last night of the war after Duryodhana's death and Kaurava defeat, Ashwathama gathered the only other surviving Kaurava warriors - Kritavarma and Kripacharya, and attacked the Pandava camp on the 18th night of the Kurukshetra war. He killed Dhrishtadyumna, Shikhandi, and many other prominent warriors of the Pandava army while they were sleeping. Ashwatthama killed all the five Upapandavas during their sleep. In some versions of the story, he believes them to be the five Pandava brothers; in others, he purposefully attacks the Pandavas' heirs in order to hurt the Pandavas emotionally. Ashwatthama was eventually cursed by Krishna for his heinous act of mercilessly the young Upapandavas and the in-womb Parikshit, to be immortal with incurable bruises and ulcers. In the Jataka tales version of the Mahabharata, Parikshit's mentors included both Sutasoma. Prativindhya, Shrutakarma, and Shatanika at least have definite longer lives in Jatakas. Ashwatthama killed the sons of all Panadavas when they are sleeping after the win of war against Kauravas.
