Rebel forces under General Alvaro Obregon defeated the Mexican Army garrison and captured Naco, Sonora.

On March 12, 1913, the federal Mexican General Pedro Ojeda evacuated Agua Prieta due to an advancing and overwhelming rebel army.

His force included about 500 men, over 300 of whom were regular army troops, the remaining were Yaqui native Americans, fighting for the Mexican government.

Obregon took control of Naco and Ojeda, with his men, surrendered to the United States Cavalry garrison of Fort Huachuca.

The famous Siege of Naco in late 1914 and early 1915 became the longest battle of the war with 119 consecutive days of combat.
