Constitutionalists Government The Battle of Casas Grandes was fought in March 1911 between the federal Mexican Army loyal to President Porfirio Díaz and rebels under Gen. Francisco I. Madero.

Rebel forces attacked the town of Casas Grandes, Chihuahua, but were driven back by the federal garrison.

[citation needed] The garrison included just over 500 infantry, who were commanded by Col. Agustín A. Valdez of Mexico's 18th Battalion.

Fighting lasted for just over two hours until 7:15 am, when another Mexican government column of 562 men reinforced the already engaged 500 troops.

He later issued a statement saying that it was his scouts' inability to detect the reinforcing federal column that led to the defeat.
