Orozco's rebellion was a major threat to the Madero government, since he had standing as a revolutionary and commanded significant forces. Madero sent Huerta to crush the rebellion. He had at his command troops of the Mexican Federal Army and these were joined by irregulars led by the revolutionary leader Pancho Villa, at Torreón in April 1912. Huerta offered Orozco's supporters ("Orozquistas") amnesty, which might have weakened their forces already suffering from lack of money and arms. Huerta's forces defeated Orozco's at Rellano in May 1912. With that victory Huerta "had suddenly become a military hero with a national reputation."
