Question: how bhima killed duryodhana in mahabharata?
Answer: Bhima victoriously attacks Duryodhana with his mace and strikes his thigh, mortally wounding Duryodhana. After having his face insultingly kicked by Bhima, Duryodhana bemoans that he was slain by unfair means, given that it was illegal to attack below the waist in a mace fight.
