I recently read an article in Military History by Martin Dugard entitled “The Warm-up War”. In the article, the author shows how the Mexican War was the first significant military experience for many West Point educated officers that would later serve in the Civil War. Notable names such as Ulysses S. Grant, Robert E. Lee, Joseph E. Johnston, and Jefferson Davis are all mentioned. These connections were an intricate part of the story of the Civil War, and as it nears completion, the House Divided project will provide users with an unprecedented ability to navigate between these connections. The web that ties many of these men goes through many years and multiple wars and is important to the greater history of the period. The article can be located in the September/October 2008 edition of Military History.
