What were the best battle formations in history? Why did they work?
Can you tell me about the best battle formations in history and why they worked?
Of course. One of the most effective battle formations in history was the Roman Testudo. The Testudo was a tight formation in which soldiers would stand closely together, raise their shields above their heads, and overlap them to create a shield "roof" that protected the formation from above. This formation was particularly effective at defending against ranged attacks, such as arrows or projectiles, as well as frontal attacks from infantry.
