So, I was reading a post on Reddit about the best movie moments and came across a strange tidbit of information. During the Battle of Pelennor Fields, the Rohirrim arrive and charge down the line of orc soldiers.
This was actually inspired by real events, namely the Battle of Vienna, wherein 30,000 cavalries charged the ottoman lines and drove them back. The Ottoman forces numbered 175,000.
What other mid evil tactics do you think Tolkien was inspired by?
