From the publishers:
In the first half of the book, Weber examines the war's military aspects, highlighting the asymmetric nature of the conflict as the world's foremost naval power with a credible professional army stood against an idealist republic with commercial and agricultural aspirations but without an adequate navy and army. Weber also attempts to recalibrate popular conceptions of the U.S. forces' generally poor performance during “Mr. Madison's War,” and frames the War of 1812 in the context of both the Jeffersonian Revolution that preceded the war and the accelerated territorial expansion and consolidation of the United States that eventually led to the American Civil War. The book's second half presents alternative outcomes for the War of 1812, reminding us that history is made, not predetermined.
