touch again with his political supporters in search for supplies to send to the revolutionary expedition, he had instructed to invade the coasts of Yucatan and Campeche.” However, the triumph of the Revolution in the north of the country would render the military campaign that Pino was preparing in the south of the Republic, with the assistance of general , his cousin, completely unnecessary. Exiled in Texas, Pino seized the opportunity to become closer to the Maderista leadership, particularly with Gustavo Madero, the "grey eminence" of the Maderista movement with whom he established "a strong friendship" and who would, going forward, “unconditionally support Pino in the Maderista movement.” After his return to Mexico, Pino Suárez participated in the Battle of Ciudad Juárez, a key city in the north of Mexico that fell to the hands of the revolutionaries on May 10, 1911, an important military victory for their cause. Faced with the loss of this important border city, President Díaz's advisers, headed by José Yves Limantour, Secretary of the Treasury, became convinced that the dictator must resign to avoid a civil war and a possible military intervention by the United States. The government decided to negotiate with the rebels and appointed Francisco S. Carvajal, a prominent jurist, as its representative. Along with Francisco Vázquez Gómez and Francisco Madero Hernández (Madero's father), Pino Suárez was appointed Maderista peace commissioner, responsible for negotiating with the federal government the terms of the Treaty of Ciudad Juárez, which would be signed on May 21, 1911. Momentously, the Treaties would mean the overthrow of the Porfirio Díaz regime after more than thirty years in power. However, they would also be harshly criticized since they ensured the dismissal of the Rebel army, thereby placing a future Madero government at the mercy of a Porfirista Federal Army that was hostile to their cause and which would eventually overthrow the Madero and Pino administration in February 1913. Venustiano Carranza, one of Madero's main advisers had advised against signing the Treaties of Ciudad Juárez, saying that "a revolution that compromises is a revolution that is lost." To preserve the constitutional order, the Treaties of Ciudad Juárez ensured that upon the resignation of President Díaz and Vice President Ramón Corral, Francisco León de la Barra, then the Foreign Secretary, would assume executive power as interim president until such time as 1911 Mexican general elections were held.
