Battle of Cannae

It just doesn't get much better than that.
Famae tibi, Hannibal! Utinam barbari spatium proprium tuum invadant et fratres trans aggere insultant, Romule!

Aztec v. Spanish.

When worlds collide. It's epic in its own sense as it's about as close as we've been to fighting the aliens. Most battles have had some kind of equality to them in a sense, these did in a totally different sense if that makes sense.

Tough question to answer, so many favourites to choose from.
Naval battle - Battle of Arginusae
Land Battle - Battle of Gaugamela

I would have to say the Battle of Trebia, mainly because i think Hannibal's strategy was genius..

Battle of Cannae
Battle of kursk
Operation Baragtion
Battle of crete

-Battle of The Hemp Bales- American Civil War in Lexington, Missouri
-Battle of Leuctra-
-Fallen Timbers-

Gotta love the Battle of Leuctra

Battle of the Kasserine Pass

Before this battle the US forces were very much 'we are here to save the Brits - Again'.
The US needed the loss to sort their heads out, get taught a lesson.
