IntroductionIt is March 9, 1916, very early in the morning a large group of Mexican revolutionaries loyal to Francisco (Pancho) Villa was heading towards the city of Columbus, NM. A raid was underway and the events that were about to happen in that border town were unknown to the detachment of U.S. soldiers from the 13th Cavalry Regiment guarding the post. HistoryJust a year after the Mexican Revolution, relations began between Mexico and the United States The United States became tense after the resignation of President Porfiro Diaz in 1911. The United States was looking for an opportunity to take advantage of Mexico's oil and mineral resources. Mexico's problems were not just tied to the United States. Britain and Germany had a collective interest in the Mexican economy. When Francisco I. Madero was recently elected after Porfiro Diaz, his anti-American strategy was revealed. This was noticed by the United States, and with the help of American diplomats, opposition groups were seeking his succession. Later Francisco I. Madero was assassinated by agents of Victoriano Huerta. Huerta dissolved the legislature and established a military dictatorship. His government was inefficient and severely repressive, and he almost immediately faced opposition from constitutionalist forces led by Venustiano Carranza, Alvaro Obregon, Pancho Villa, and Emiliano Zapata. They gained the support of Woodrow Wilson, the newly elected president of the United States, who refused to recognize Huerta.1 The United States supported revolutionary groups that opposed Victoriano Huerta. Among the rebels was the leader Doroteo Arango better known as Pancho Villa. After Huerta's exile in 1914, Venustiano Carranza obtained the presidency of Mexico as a provisional government... energy and sophisticated equipment. A wrong tactic was to show strength in military use and technology, not understanding the population and obtaining foreign government support. Even when the operation failed to capture Villa, it provided valuable training experience for all the men who took part. One of the largest American military operations since the Civil War, it provided lessons for later use in World War I. Works Cited Aguirre Botello, Manuel. Pancho Villa Ataca Columbus, 1916.
