Jeopardy Was Wrong!

I wish I could have been on Jeopardy tonight and rang in when this answer came up:

I sat there confused and the guy who answers it also seems to just guess: who are the Huns?  Why would this be a bit confusing to those of us who actually studied Ancient History?  Well, the Huns invaded the Balkans in 447 A.D.  Unless Attila the Hun (the aptly named "Scourge of God") somehow managed to travel back in time to fight the Spartans...

First time I have ever noticed a mistake on the show.  I feel so smart.
