Read it, loved it! My particular favorite part is the philosophy on planning a siege, knowing when to continue and when to back off. Sieges are costly, after all. This book is great for war and great for life in general. Have you ever read the Go Rin No Sho by Miyamoto Musashi? I wish I could find the librarian who turned me on to this book and thank her. Barnes & Noble now publishes it under the English translation of "The Book of Five Rings". I recommend it highly!
