Though primarily fought in the field, the American Revolution saw fortifications play an important part in some of the most important campaigns of the war. Field fortifications were developed around major towns including Boston, New York and Savannah and frontier forts--at Stanwix, Niagara and Cumberland--were to all be touched by the war.

This book details all the types of fortification used throughout the conflict, the engineers on all sides who constructed and maintained them, and the actions fought around and over them.
