What were the best battle formations in history? Why did they work?
That makes sense. Were there any particular battles where these formations were especially effective?
Yes, for example, at the Battle of Cannae, the Romans used the Testudo formation to great effect against the Carthaginian army. And at the Battle of Marathon, the Greek Phalanx was instrumental in holding off the Persians and securing a victory.
