This one is for Sarah, who always complains that no-one writes about medieval logistics.
You may have heard about the war wagons of the fifteenth-century Hussite Wars (if you haven’t, look them up; they’re very cool), but here’s a wagon story from the middle ages you’ve probably never heard.
Historian Ronnie Ellenblum says that one of the big advantages that Crusader armies had in twelfth-century sieges was a superior siege train. Using heavy four-wheeled carts that weren’t otherwise in use in the region, the Crusaders were able to bringing in pre-cut heavy beams and other materials they used to build siege towers and stone-throwing artillery that helped them capture thirteen cities in twenty-five years. The wagons may have been slow, but they were part of a cutting-edge siege system that, once the tables were turned, forced the development of monster Crusader castles like Belvoir, Krak des Chevaliers, and ‘Athlit to resist the same sorts of attacks.
