The White Council arrives in Dol Guldur and drives Sauron out, causing him to flee back into Mordor. In The Hobbit: Desolation of Smaug, Sauron attacks Gandalf and overthrows him (in his big scary fog like form) yet he doesn't appear to battle at all against the White Council in The Battle of the Five Armies, the Ringwraiths do all the fighting.
How does the overthrow of Dol Guldur in the movie compare to the books? Did an actual battle with Sauron take place in the books or did he simply flee upon the arrival of the White Council? Any explanation of why Sauron didn't seem to battle with the White Council in the film version like he did against Gandalf?
