The Inside Out Fortification

This month, I am doing castles as the theme of my Inktober sketches. I've always been amused by the bit in So Long and Thanks for All the Fish where Wonko the Sane builds the Asylum, an inside out building to contain the world gone mad. 

This is probably my first contact with this concept of an inside out structure. 

However, real life shows that Wonko the Sane's Asylum isn't nuts. Apparently Julius Caesar did this in his siege craft. In a particularly interesting conflict, Caesar attacked fortification of Alesia. 

Muriel Gottrop in December 2004 from Wikipedia

The Gallic leader, Vercingetorix took refuge in the oppidum (an Iron Age Fortified town) with his 80,000 men. Caesar decided it was more prudent to siege the town rather than storm it. However, this required building a 10 mile long wall around Alesia. It wasn't perfect, but it was effective. 

When the Gallic relief force showed up, Caesar built a second wall around his own forces and the Roman's world collapsed into a one half mile strip of land between his walls.  

As the siege progressed, Vercingetorix turned out many of the civilians in the hopes that they would be captured by the Romans and fed. Caesar refused this option and didn't attempt to capture or kill any of them. A siege requires people to consume the food, so in turning them away, he didn't weaken his own position by wasting energy on killing or capturing them. As you can see from the map, neither of Caesar's walls were perfect and probably some people simply walked away. 

The Romans never broke into the walls of Alesia, but Vercingetorix was forced to surrender. He and the chieftains were killed and the Roman Legions took 40,000 captives as slaves. 

Most of this account was written by Caesar himself, so many of the numbers are probably inflated. It is fairly reasonable to assume that Caesar reported accurate numbers for his own forces but magnified the Gallic forces to look better. He said that there were 80,000 following Vercingetorix and the Gallic relief force numbered 250,000. This is pretty unlikely. 

But what we can take from this is, Caesar only took half of the people involved captive as slaves and he literally built 2 walls at least 10 miles long. 

From the prospective of gaming, we can see that a lot of historical figures do incredible things while not resorting to a scorched earth policy or glassing event. Caesar really played himself as a benevolent leader and ran a policy of forgiving his enemies. This probably explains why Vercingetorix surrendered himself. Either he though that was the best option for his followers to survive and there was a slight chance he, himself, would survive. Many of Caesar opponents killed themselves to spite him when they lost. 

These sorts of examples highlight why people surrender in battles and I would totally make that concept a thing in my games if it ever came to the party surrendering. I posted about that almost a year ago. If more games incorporated an honor mechanic, it would probably happen more often. 

One further tieback to game is my frustration of the lack of realistic scales for fortifications. Alesia was not a particularly massive fortified position, but if Caesar stood back a couple of miles, it's far larger than what is shown in modules like Keep on the Borderlands. My players in our B2 sessions were completely stymied by the huge area and I figure the area represented on the map is too small by a good margin. 

I'll be posting maps and drawings of my ideas soon. Stay tuned.
