I wanted to compare the two greatest military units in the ancient world, the legion versus the Greek phalanx.
From the Persian Wars all the way to the wars against the Romans, the Greek phalanx was arguably the best fighting formation up until that time- its techniques were simple but effective: put lots of men with heavy shields and armor together in a tight formation, arm them with spears (later on, pikes) and smash their way through the opposition. This formation was so effective that this style of fighting spread throughout the Western world and was the dominant formation for the next few hundred years.
Now the Romans never really invented anything in terms of war. In fact during the early days of Rome, their army was built upon the Etruscan way of fighting, which was the phalanx. But after being defeated a few times by a tough hill tribe called the Samnites- the Romans decided to copy the Samnite way of fighting- their first two ranks got rid of their heavy spears and instead started to use light javelins with which to throw at the enemy before engaging with a small stabbing sword called the gladius (which was either copied from the Iberians or the Celts) and also to stop fighting in close formation and instead use the Samnite way of the checkerboard formation by having space in between you and the one beside you, this way you could fight effectively in uneven terrain and if you were wounded or exhausted, you could retreat backwards behind the front line because of the gaps and the man behind you would then take your place, this allowed the Romans to continuously apply force at the front lines so they kept fighting, like a machine. However, their third ranks, which had their most elite soldiers, still retained the traditional phalanx formation (as a back up) until the Marian reforms hundreds of years later.
Now there were around five battles in which Greek hoplites faced Roman legionnaires- three of these were fought by King Pyrrhus when he attempted to conquer the Italian peninsula. The first two battles he won and the third was inconclusive.
The two other times the Romans faced the Greek phalanx were both won by the legions. In the battle of Pydna, the Romans faced a Macedonian army made of mostly phalanx troops. The Romans faced them on the slope of the mountain the the Macedonians had to fight uphill, in the early stages of the battle the phalanx was actually able to push back the Roman center but lost its cohesion because of the rough terrain, the Romans were able to adjust in time and got around the flanks of the Macedonians as their formation began to break apart and defeated them- however, even though the Macedonians had a cavalry contingent, they never used it and instead fled from the battle so that was one hell of a mistake. In the battle of Magnesia the Romans faced off against the Seleucids and the former was able to achieve tactical surprise and panicked the war elephants of the Seleucids in a surprise attack which drove them into the main Seleucid phalanx and broke its back before they could even react- though it was a great victory there were somewhat extenuating circumstances as to why the Romans were able to defeat the phalanx at that time.
While the two examples obviously demonstrate the versatility of the legion over the phalanx there were a number of reasons why the Greeks were defeated, though not necessarily due to the phalanx itself.
Another possible theory is that of the Carthaginians. While we do know that Hannibal had a mixed army of mercenaries with him when he invaded Italy during the 2[SUP]nd[/SUP] Punic War, we have no records of what the Carthaginians actually fielded in terms of troops and formations other than scant descriptions of their Celtic, Hispanic mercenaries and Numidian cavalry. Were the Carthaginian troops in fact, using the phalanx to deliver Rome’s greatest defeat at the battle of Cannae? We do know later on in his campaign that after Cannae Hannibal’s troops looted the Roman dead and used their equipment to the point where they became mirror units to the legions they were facing but were Hannibal’s Carthaginian veterans in fact, Hoplites operating in a phalanx? I guess we may never know.
What do you guys/gals think?
