Boxing legend Oscar De La Hoya hosts this History Channel two-hour (90 minute program time) special exploring the war that few American history books describe in depth, as it represents the only time in history when the United States could be considered a nation of conquest. As the result of the war, President James Polk was able to expand American borders to the Pacific Ocean, taking over nearly half of Mexico's territory. American and Mexican historians tell both sides of the story ... how the war began, how it was fought and who ultimately was responsible for the outcome.
