Jarasandha vadha is the twenty third upa parva included in the second Maha parva named Sabha parva in the epic, Mahabharata. Vyshampayana had narrated the historical events to Janamejaya on his queries:
How Krishna planned to face Jarasandha with Bhima and Arjuna?
Krishna had accompanied Arjuna and Bhima for facing Jarasandha. They would move without any weapons and enter his palace from the rear door. Then, Jarasandha would fight with Bhima like wrestling, since his two commandos Hamsa and Dibhaka had drowned in the River Yamuna, and their death had been announced. There were three drums installed on the top of a mountain and they had damaged it on reaching the Magadha town. It was meant for alarming the army so they disabled it.
