Mahabharat Season 23

On the 9th day, Krishna, overwhelmed by anger at the apparent inability of Arjuna to defeat Bhishma, rushed towards the Kaurava commander, the wheel of a fallen chariot in his hands. Bhishma laid down his arms and stood ready to die at the hands of the Lord, but Arjuna stopped him, reminding of his promise not to wield a weapon. Realizing that the war could not be won as long as Bhishma was standing, Krishna suggested the strategy of placing a eunuch in the field to face him.
