I will begin the first series of interesting maps that shows the geography of North America, starting within the United States. This map shows what the Military Forts and Military Districts were between the US-Mexico War and the Civil War. This would include the “Extreme Line of Outposts in 1845”, several major roads to the west, the various military departments including the Department of Texas, and a number of short lived forts west of the Mississippi. This map is linked to the website below. I have found an interest in the military of the United States a lot of the time and thus decided to start off this series with this interesting map from around the time of the American Civil War.
