The Western division, under Obregon, captured one by one all the border towns, and later most of the seaports,--and in spite of the fact that Guaymas stuck to the last, the Western division had so effectively cooped up the Federals in that port, that they were not interfering with their downward course towards Guadalajara. General Gonzalez acted on the same principle. He first captured the border towns, and then Victoria the capital of Tamaulipas. With the fall of Tampico, the Federals in San Luis Potosí were outflanked. General Villa did the same. After he controlled the border cities, he concentrated all his energies on the capture of Torreon. The three chiefs of divisions, East, North and West, co-operated with one another under the direction of Carranza. They were supplied with money, arms and ammunition by the organization created by Carranza in the different States, and directed by the efforts of the members of the provisional cabinet. Zapata by his activity, aided by that of Genovevo de la O and several other chiefs in the South, forced Huerta to keep about forty thousand soldiers in the South. The railroads created new strategic lines-- 1st. From Nogales at the border, the railroad goes almost uninterruptedly through Sonora, Sinaloa and Tepic, with the exception of a gap between Tepic and Guadalajara. 2d. From Juarez the railroad runs through Chihuahua, Durango and Zacatecas into Aguascalientes. 3d. From Ciudad Porfirio Diaz through Coahuila into Nuevo Leon, and to San Luis Potosí, and from Monterrey to Tampico. They represent the lines which had to be controlled by the three divisions. Then there were lines connecting Torreon with Saltillo and Monterrey,--and Aguascalientes with San Luis Potosí. The assertion that either one of the three chiefs of the divisions was solely responsible for the success of the revolution is absurd and inexact. Let us admit for instance, that Obregon had reached Guadalajara, and tried to march through Celaya to Mexico City alone, before Villa had taken Aguascalientes, or General Gutierrez taken San Luis Potosí. He would then have been attacked in the rear by the Federals. In Villa’s case, if he had captured Aguascalientes and tried to march south to Mexico City, without waiting for Obregon to take Guadalajara, or General Gutierrez, San Luis Potosí, he would have also been attacked in the rear. General Gonzalez in his turn, could not march south as long as San Luis Potosí was in the possession of Federals.
