What tactics did the Romans use?

The Roman army used many different tactics in warfare. Roman infantry was deployed in maniples or cohorts in blocks like a chessboard. Roman maniples aggressively attacked from the front and side, usually protecting themselves with their shields to form a "tortoise" that could move across the battlefield and resist enemy fire. The Romans also used military intelligence, subterfuge, and siege warfare to better their enemies.

Who did the Romans fight?

The Romans fought many other cultures as they expanded their empire. They fought and defeated other Italian tribes, Gauls in western Europe, the Carthaginians in North Africa, and Celtic Britons in Britain. The Romans also fought, but with less success, the Germanic tribes in northern Europe and the Parthians in the Middle East.

Why was the Roman army so effective?

The Roman army was effective because it was composed of well-trained, well-armed, and disciplined professional troops. Roman commanders employed a wide variety of tactics on the battlefield, they used military intelligence and adapted the more successful elements of their enemies' warfare. Roman warfare was also successful because of excellent logistics.

Did the Romans lose any wars?

The Romans had many successes but they did sometimes lose. Notable losses came against the Germanic tribes and the Parthians. In both cases, the Romans underestimated their enemy and the difficulties of the local conditions.

Roman Warfare Timeline

Definition

Roman warfare was remarkably successful over many centuries and across many territories. This was due to several important factors. Italy was a peninsula not easily attacked, there was a huge pool of fighting men to draw upon, a disciplined and innovative army, a centralised command and line of supply, expert engineers, and effective diplomacy through a network of allies.
