Originally published in 1966, this book demonstrates how far history research and writing has come since then. It is full of factual information about the comings and goings at the for throughout its history, but it is extremely dry and the research not very well documented. Additionally, the author uses terms that are not acceptable in the historical community (or elsewhere) now, such as calling Native Americans "redskins" and "scalpers".
I'm a history teacher who has done a lot of research into US fortifications, and even I found this book extremely hard to get through.
