The War of 1812 was an extremely complicated war motivated by British seizures of American vessels and goods, American desire to expand into Canada, and impressment of American sailors into the British Navy. However, these are merely the immediate causes. To fully understand the War of 1812, one must delve deeper into history. This book does just that, as it covers the period leading up to the war (1803-1812) and the events of the war itself (1812-1815) through the use of a dictionary consisting of more than 1,400 cross-referenced entries covering descriptions of engagements, ships, weaponry, the compositions of regiments, significant political and military figures, and a full list of key places, issues and terms. Also included are 21 photographs, 6 maps, a chronology of events, an introductory essay, and a comprehensive bibliography, subdivided by topic and fully annotated.
