An exploration of the American Army between 1812 and 1814. It concentrates exclusively on the regular US Army units which formed the backbone of the forces which fought the British along the Canadian frontier and at New Orleans in the war which saw the British burn Washington and inspired Francis Scott Key to write "The Star Spangled Banner". This volume revises and replaces one half of "Men-at-arms" Volume 226, "The American War 1812-14" which detailed the British and US forces in this conflict at a more superficial level.
