Krishna and Bhishma Fight | Tales of Mahabharata
Bhishma had promised Duryodhana that he would kill Arjuna unless Krishna himself takes up arms. Krishna knew that if Bhishma used all his powers, Arjuna is no match for him, and when the battle ensued between Arjuna and Bhishma, Bhishma came very close to defeating Arjuna. This is when Krishna picked up a chariot wheel and charged towards Bhishma. Bhishma put down his bow and arrow and Arjuna was saved.
