The PLM organized several uprisings against the Porfirio Díaz regime, all of which were violently repressed. The PLM Program influenced the
Cananea strike, and
Río Blanco strike, as well as the
Acayucan rebellion. On
16 September, the PLM initiated their revolutionary plan. When the groups operating in the United States took over the main border customs and reinforced the supply of weapons, the 44 guerilla groups (totalling 2200 fighters) all over the republic would rise up in arms. However most of the liberals were discovered by the US police, who seized weapons and documents that discovered the insurrection plans, so it had to be postponed. 26 September was set as the new date to start the Revolution. A group of liberals attacked
Jiménez but after a few hours federal forces arrived, outnumbering and forcing them to flee. Other attacks were carried out in
Monclova,
Zaragoza,
Piedras Negras and other small towns in
Coahuila, to similar results. On 30 September, the
Acayucan rebellion began, led by Hilario C. Salas and Cándido Donato Padua, PLM delegates from
Veracruz and
Tabasco. In
Acayucan the clashes against the army lasted 4 days. Most of the rebels died, some fled to the Soteapan mountain range where they reorganized the guerrilla war, continuing the fight until 1911. On 16 October, a third insurrectional attempt was made in
Camargo, which was also defeated. On 19 October, the group from
El Paso, organized by
Ricardo Flores Magón, ventured into
Ciudad Juarez, but were discovered crossing the border by federal soldiers, who were already aware of the uprising. The next day the rest of the insurgents were arrested in El Paso by immigration agents and
Pinkerton detectives, but Magón managed to escape. On 24 June 1908 the PLM attacked
Viesca, but were repelled and defeated. The leaders were apprehended and sent to the
political prison of
San Juan de Ulúa in
Veracruz. On 26 June, the liberals attacked
Acuña,
Casas Grandes and
Palomas. There was also belligerent PLM activity in
Oaxaca,
Puebla,
Tlaxcala and
Morelos. The railroad strike that paralyzed the northern part of the country that year was also influenced by the PLM. A Pinkerton agent in
St. Louis declared that, in 1908, 180 members of the PLM had been arrested and placed in Mexican prisons, so "the danger of a revolution had passed". But in 1909,
Práxedis G. Guerrero published a series of manifestos aimed at the workers of the world, and urged Mexicans to rise up in rebellion. The most effective weapon of the PLM was the press. Even in exile, it had at least 7 publications in different locations, all of which were gradually suppressed by the authorities. ==The Mexican Libertarian Army==
