To Siege, or Not to Siege?

The basic siege tactic is to wait around until your enemy gets desperate enough to surrender, rather than starve to death. Sure, it's effective if the city has no allies and no hope of relief, but if they're well supplied, you could be waiting for years while your homestead's crops wither and you contract dysentery. Therefore, since they excelled at every other form of combat, it makes perfect sense that the Romans would use their engineering skills and upgrade a few local weapons to make them capable of destroying walls, piercing armor, and making life for the besieged as uncomfortable as possible.

The Scorpio was the smallest of the artillery weapons, and was mostly used for sniping any one target within one hundred meters. It was basically a big crossbow whose bow apparatus consisted of two wooden arms connected to a torsion-mechanism. Its bolts could pierce the strongest armor, and the machine itself could be operated by one person. Every legion was supported by at least 60 Scorpios, giving the infantry a cover of deadly bolts to retreat under, should the battle prove contentious enough to warrant a second or third line engagement. It was mostly used to support Roman infantry in the field and in a siege, they were angled and fired in a parabolic fashion, quadrupling their range, but eliminating their precision. Still, the chance of getting instantly killed by one of 60 iron-tipped bolts that could rain from the sky any second was enough to cause the right kind of disruption within the besieged city.

The Ballistae was the Scorpio's steroid-popping big brother. Being much larger and more powerful, there were probably only a few Ballistae per legion, though reinforcements might bring more if there was a siege. In its early days, it hurled massive bolts over 460 meters, often impaling several men at once. Its purpose was mostly to cause fear in the beginning, though later it met with greater advancements which made it a very useful piece of field artillery. It was attached to wagons which would pull the terrible giant crossbow to wherever they could be deployed effectively, and let them rip into the enemy ranks.

Let's face it: the real ultimate weapon of the ancient world was fire. Still a largely misunderstood and uncontrollable force in those days, the sight of fire alone could devastate an army's morale, much less the thought of having balls of the stuff thrown at them. The Onager existed for just this purpose. You may notice in the picture that the payload is contained in a sling, which increases its range, but pretty much destroys any sense of precision. It worked well enough to hurl pots of pitch over enemy walls to set alight whatever they happened to land on, wrecking food supplies, killing soldiers or civilians, and giving yet another calamity for besieged cities to fear.

In the Medieval period, many of these weapons would evolve in different ways; the Scorpio being replaced by the crossbow, the Ballistae by . . . well, better Ballistae, and the Onager by the catapult, which had a fixed bowl instead of a sling and was used to hurl hot coals or large boulders at whatever you want to die. As Hannibal learned the hard way, you can't take a city without laying a siege, and the Romans show us time and time again that it is always best to be prepared.

Archimedes

Unfortunately, Archimedes is one of those semi-mythical guys who wasn't written about heavily until hundreds of years after his death. What we do know about him is a combination of contemporary and later sources, all of which agree on at least one thing: he was crazy smart.

He approximated pi to an unprecedented degree, which by itself is one heck of an accomplishment. He built world-changing inventions, created new mathematical formulas which incorporated infinity and zero (two concepts which scared the daylights out of Aristotle), applied buoyancy, and created complicated pulley systems which allowed for the earliest cranes to be built. I have focused mostly on how his inventions applied to warfare and farming, but those were the two chief interests of the ancient Mediterranean, when you get right down to it.

Though he died an untimely death at the hands of a foolish Roman Legionnaire, his concepts and inventions continued to change history long after his death. That is, the inventions that they could duplicate continued to change the world. There were several items the plunderers found in his workshop which could not be re-created and were taken as trophies by Marcellus and his Captains. One of them was a sphere with gears and levers which could calculate the exact position of the known planets.

The Siege of Syracuse

Located in south-eastern Sicily, Syracuse was an old Corinthian-Greek Colony with old-time values. Ruled over by kings and tyrants since its founding in 733 BCE, Syracuse enjoyed the many benefits of its central Mediterranean locale and became very wealthy through trade with Egypt, Rome, Carthage, Asia Minor, Palestine, and Spain. After the Pyrrhic war in 275 BCE, however, it was the sole remaining Greek settlement west of the Peninsula itself, and in a very tenuous position sandwiched between Rome and Carthage.

Syracuse survived for quite a while after Pyrrhus' final defeat because its leaders made smart alliances and used skilled diplomacy to ensure the protection of either Rome or Carthage. When the first Punic War broke out, Syracuse was at the center of the action and made an alliance with Carthage from fear of Rome. Luckily, Rome and Carthage fought each other so bitterly that by the time Rome got around to dealing with the unlucky Sicilian Greeks, they had already lost so many in battle that they were willing to settle for an apology and a cut of their trade. However, when the second Punic War broke out, Syracuse made the mistake of allying with Carthage again, and the Romans were determined to make them pay. However, Roman vengeance would come at a high cost to the Republic because of one resident of Syracuse whose mind possessed knowledge that could bring both great prosperity and very great destruction. This man's name was Archimedes.

I like to think of Archimedes as a sort of ancient world Da Vinci, except without the moral qualms about creating weapons. Where Da Vinci was purposefully putting gears in the wrong place so that his designs would ultimately fail, Archimedes was not only sketching these out, but utilizing them to a terrible degree of success. For this week's Famous Friday, we'll delve into Archimedes' discoveries in greater detail, but since it's Military Monday, let's focus on his original and horrific siege weapons.

The most famous of his weapons was The Claw, which utilized pulleys and complicated weight balancing to capsize Roman Triremes. Seriously, this crane-like weapon would hook onto the bow or stern of the boat, lift it out of the water, and send it crashing against the nearby rocks. Each boat carried about two hundred soldiers, so you can imagine the carnage that ensued when this happened over and over:


Another of his creations was an improved catapult. Again, using pulleys and counterweights, he was able to create an engine capable of throwing a 500 pound rock with much better accuracy than the inferior Roman scorpions and ballistae. He also contributed to the building of other weapons which could fire missiles and keep the Romans at bay.

The most controversial of his creations was his 'death ray.' Several authorities have tested it using various techniques, and some have been successful, while most have ended in a wash. Supposedly, Archimedes built a large array of bronze mirrors which could be turned, focusing their reflected light into a concentrated beam onto an approaching ship. The Roman ships, which were sealed with tar, caught on fire and sunk. While this does seem a bit far-fetched, I wouldn't put it past old Archie to give it a try. After all, it was Hiero II, the king of Syracuse and relative of Archimedes, who frequently challenged the genius and gave him the funding he needed to build better weapons since the first Punic War, so why wouldn't this mathematician try literally everything he could think of? Were there easier ways to light ships on fire? Yeah, lots. But if I were an invading Roman, I might think twice about mixing it up with an enemy who can light my ships on fire without shooting anything.

Syracuse eventually fell to sheer Roman determination, and Archimedes was killed, possibly while drawing circles in the sand. If not for him, the last Greek colony on Italian soil would surely have fallen in the first year, and Carthage wouldn't have stood a chance of surviving the Second Punic War. By the time the Roman army came to the gates of Carthage, they had suffered so many casualties from Syracuse and from fighting Hannibal for ten years that they allowed Carthage to live, albeit under severe economic sanctions. And when Carthage was finally leveled in the Third Punic War, there were no more brilliant mathematicians around to set Romans on fire from a distance.
