Guarding the Frontier was first published in 1935. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions."For almost a century the defense of the frontier was the chief consideration in the military policy of the United States," Dr. Wesley observes. His book is the first detailed historical study of the military policy of the United States in the years immediately following the War of 1812, the period during which its policy was becoming clearly defined.

The author demonstrates the importance of Indian affairs, of the factory system, and of the fur trade as elements in the westward expansion of the United States
