In the 300-year time span covered by this book, gunpowder artillery was developed from a novelty to a serious weapon of war. By 1600 the cannon was to be found in large numbers on the battlefield, on board ship and on defensive positions on buildings and city walls. Illustrated with contemporary and modern photographs of surviving and recreated weapons, Early Gunpowder Artillery 1300-1600 sheds light on these earliest ancestors of the modern cannon and field gun. Looking not only at the weapons themselves, but also at the men who made and used them, and the tactics with which they were deployed, this is the ideal introduction for anyone interested in medieval warfare.
See my review of Norris' "Gunpowder Artillery 1600-1700". A very good, frustratingly close to an excellent book. One addendum to the above mentioned review is the relatively poor photo reproduction.
