@Francis,
So, Hannibal prevented the Romans from expanding in Europe?

No that event happen a "few” hundred years before when the Roman Republic was in place not the Roman Empire and they was in a death struggle with the city of Carthage. Sorry I am not enough of an expert to have all the dates at my fingers tips.
The lost of the three legions was at the hands of German tribes and occurs when Augustus was the Emperor during the Empire stage.
We are dealing with a few thousands years of history here and therefore it can indeed become confusing.
There is three large period of Rome history, first the Republic, then the Empire period and then the period after the break up of the Empire between West and the fall of the Western half.
The Eastern half we now call the Byzantine Empire and it did not fall until the 14 century or so to the Muslins.
As I said it can be very confusing as we are dealing with one hell of a time frame here
