The French & English in Western Pennsylvania: Their Armies, Their Forts, Their People, 1749-1764.  The author brings his specialized knowledge as an architectural historian to show what colonial forts looked like, where they stood, who built them and why, what materials were used in building them, and how they varied in design to fit different military purposes. This book describes twenty-two forts built by the French, English, and the colonists in Maryland, Virginia, and Pennsylvania, from tiny outposts built by the Ohio Company at Wills Creek to the fortresses that guarded the Ohio at Pittsburgh, first the French Fort Duquesne and later the English Fort Pitt. Sixty-seven black and white photographs with 104 drawings and maps.
