The Hobbit: The Battle Of The Five Armies Movie tells about battle between five armies. I counted only four.
- Dwarves Army (Lead by Throrin)
- Elves army (Lead by Thranduil?)
- Orcs army (Lead by Azog)
- Lake Town people (Lead by Bard)(I think,this is not an army)
What is the fifth army. Please list the all five armies and its leaders?
