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.
