As revolutions cost money and none was forthcoming or could be had after the murder of President Madero and Vice-president Suarez, Carranza convened the state legislation of Coahuila demanding from it the refusal of allegiance asked by General Huerta, and a vote to turn over to him the money of the state treasury for revolutionary purposes. Then he rode with a few followers on horseback through the federal lines across the mountains of the States of Durango and Sinaloa into Sonora, a State not connected directly by rail with Mexico City. Being more free there from molestation by federal soldiers than the other border States he helped to organize the government and made his headquarters for a while in Hermosillo, Sonora. The seizure of the border towns of Nogales and Agua Prieta opened the way to the importation of arms and ammunition and to the receipts of the custom houses. As the revolutionary troops on the border States captured more custom houses, as happened in Juarez, Ciudad P. Diaz, Nuevo Laredo, Matamoros and finally the seaport of Tampico, the revenues increased as well as the facilities for the importation of foodstuffs, clothing and ammunition. Carranza and his sub-chiefs had five different methods of acquiring financial support in northern Mexico. 1. The interior war tax, which was paid by Mexican and foreign commercial mining and industrial firms doing business in the northern States, besides the taxes paid by the “haciendados” or land owners, farmers. 2. Custom house duties at all the border towns on imports and exports, that is to say on foodstuffs, cattle, ore, metal, clothing, etc., which were paid in gold as arms and ammunition bought by the rebels had to be paid in gold. 3. Forced loans from the enemies of the Constitutionalists. 4. Voluntary loans by the friends of the revolution such as rich Mexican landowners, capitalists and miners. 5. The creation of an interior debt by the issue of paper money to be circulated in all the territory under the power of the revolution and the prohibition to circulate the bills issued by the Banco Nacional of Mexico City on February 18th, 1913, at the order of General Huerta.
