Secondly. That we hope that the Convention which is to take place on the first of October, when all the Constitutionalist forces will be represented, to solve the great problems of our country, will put them into effect with the assistance of the arms which we will not relinquish until our ideals have been fulfilled. Hoping for an answer to give our definite resolution, we salute you affectionately. GENERAL DOMINGO ARRIETA, GENERAL MARIANO ARRIETA. As an answer, Villa sent General Urbina against the Arrieta Brothers. Urbina and his forces were defeated, and the general badly wounded. Innocent, well-meaning, but utterly deceived Villa! If he only knew that the Cientifícos whom he accuses of having affiliated with Carranza, are really pulling their wires from New York, and using him (Villa) as the tool to eliminate Carranza, and this because the first chief intends to carry out all the radical reforms of the revolution. CHAPTER XIV CAMPAIGN OF GENERAL GONZALEZ IN THE EAST Like most of the campaigns in the north of Mexico, where the strategic objectives are the border towns, so the campaign of General Gonzalez was fought, first for the possession of Piedras Negras (Ciudad Porfirio Diaz), Nuevo Laredo, Camargo and Matamoros, and later for the control of Tamaulipas. The first battle of the revolution against Huerta was fought at Anhelo and ended in a defeat. Then Venustiano Carranza, with his brother Jesus Carranza, and Pablo Gonzalez, took Piedras Negras. Huerta, as well as his generals, were of the opinion that if Carranza was captured and shot, it would end the constitutionalist revolution then and there. Therefore, they concentrated all their efforts upon Piedras Negras, which was defended by four hundred men. More than 9,000 Federals were sent against them, and although the revolutionists were forced to leave, the enemy did not succeed in capturing the leaders. [Illustration: GENERAL PABLO GONZALEZ Chief of the Eastern Division] Then Pablo Gonzalez, with the help of Jesus Carranza, roamed all over the States of Coahuila and Nuevo Leon defeating over twenty Federal garrisons and capturing the much needed arms and ammunition, which were so scarce and hard to get at the beginning of the struggle. It is a fact worth noticing that, in the three campaigns in the North, Centre and South, the revolutionists captured many cities, and then departed. To the lay mind it seems absurd to fight so hard to capture a city, and then to let it go almost immediately without even waiting for the Federals to retake it. Nevertheless, it was good tactics. The Federal garrisons offered big stores of war material, while the cities supplied them with food, clothing and money. Monterrey was attacked twice without success, and there was no chance of victory until Torreon, Piedras Negras, Nuevo Laredo, Matamoros and Tampico were in the hands of Pablo Gonzalez. When that was done, Monterrey was automatically evacuated by the Federals.
