First Battle of Agua Prieta
The First Battle of Agua Prieta was fought between the supporters of Francisco Madero and federal troops of Porfirio Díaz in April 1911, at Agua Prieta, Sonora, in the initial phase of the Mexican Revolution.
The battle was significant in that it was the first time railroads were used by the rebels to gain surprise and that US forces got involved in the fighting. The town was recaptured by federal troops two weeks later once additional reinforcements arrived. This battle was a turning point in the Mexican revolution
