How Medieval Clerks Shaped Warfare

We often think of medieval warfare in terms of warriors and their characteristic weapons. Jim Bradbury is a good example. In his The Medieval Siege he devotes a solid chapter to medieval siege weapons including mines and miners, the use of ladders for scaling walls, siege weapons, etc.  Gunpowder weapons get appropriate coverage. This chapter gives us a good idea of the variety of specialists that might make up a well-organized army.
