Medieval Sieges & Siegecraft Book

Clashes of armored knights and chivalrous duels are the face of medieval warfare, but the heart was control of fortified places, castles, and walled cities which were the economic and military heart of the period. There's a lot that can be said about sieges, but this book isn't it. Rather than any kind of organized approach to the subject, it's a series of disconnected anecdotes across regions and centuries, with only the vaguest thematic link between retellings from medieval chronicles, and the most cursory analysis and synthesis. This book is just barely good enough for me to keep reading, which is not praise. At least it's short.
