I recently talked to one of my friends who was telling me the story from Mahabharata(that he has read from an old book) where there was a fight between Lord Hanuman and Bheeshma in the Kurukshetra battle. Lord Hanuman was protecting Arjun from Bheeshma's arrows. Here, Bheeshma had an upper hand over Lord Hanuman as Lord Hanuman was throwing stones at Bheeshma but Bheeshma destroyed them with his arrows. Then Lord Hanuman went out of Kurukshetra to get more stones and in the meantime fight between Arjun and Bheeshma continued.
I wanted to know whether this story is there is Mahabharata or is just a folklore. And if it is there then did Lord Hanuman continued his fight with Bheeshma later on and what was the result?
