In Britain, you’re never too far from a castle. These landmark structures are key to the history of the country, the rise and fall of great powers being marked upon their walls. In this episode, Dan Spencer takes a closer look at the use of castles in the Wars of the Roses both as defensive garrisons and as headquarters. Dan is a military historian and leading expert in the study of early gunpowder weapons, artillery fortifications and castles. He also takes Matt through the developing use of guns during this period, and the everyday health and safety mishaps which came from operating them.
