Rubio-Campillo, Xavier, Francesc Xavier Hernàndez Cardona, and Maria Yubero-Gómez. “The Spatiotemporal Model of an 18th-Century City Siege.” Social Science Computer Review, November 17, 2014, 0894439314558559. doi:10.1177/0894439314558559.
The importance of terrain in warfare has often encouraged an intense relation between military conflicts and the use of techniques designed to understand space. This is especially relevant since the modern era, where the engineers who built and assaulted city defenses recorded the events with diverse documentation, including reports, diagrams, and maps. A large number of these sources contain spatial and temporal information, but it is difficult to integrate them into a common research framework due to its heterogeneity. In this context, geographical information science provides the necessary tools to explore an interdisciplinary analysis of these military actions. This article proposes a new approach to the study of sieges using a spatiotemporal formal model capable of integrating cartography, archaeological, and textual primary sources and terrain information. Its main aim is to show how concrete research questions and hypotheses can be explored using a formal model of this type of historical events. The methodology is applied to a particular case study: the French–Spanish siege of Barcelona that occurred in 1714. The protagonists faithfully recorded the development of the action, providing essential information for the model. Besides, different authors depicted the event as the paradigm of a city siege. For this reason, the model is also used to explore why real actions deviated from theoretical guidelines, clearly defined in different manuals. We use this scenario to explore two issues: (a) why the attackers chose to assault a particular city sector and (b) the factors that explain the casualties of the besiegers. We conclude that we need methodological tools capable of integrating heterogeneous information to improve the understanding of siege warfare that affected not only military conflict but also the shape of European urban landscapes.
That article includes some interesting discussion and insightful maps of the attacks, siege casualties, etc. Now if only somebody did it for every siege! I’ve got dibs on Douai 1710, if I ever take the time to play around with GIS.
With other military historians finally catching up with the serious study of Louisquatorzian siegecraft, I may need to dust off a few ideas I had in dissertation version 0.5 (all done in AutoCAD):
Siege batteries, Douai 1710
Casualties by approach by day, Douai 1710
I also have the number of daily workers, so a casualty rate over the length of the siege could easily be calculated.

And, finally, a colorful map that emphasizes the importance of musketry for the defense:
Garrison volume of musketfire (theoretical)
Now I remember why it took me so long to finish my dissertation – because I wrote 1.5 of them instead of just one.
