“No re-election” and “effective suffrage” were the two catch-words of Madero. It was very similar to that of Porfirio Diaz when he swept everything before him. At no time were there, according to the best reports that can be obtained, more than a few thousand men enrolled under the Madero banner. These troops were scattered throughout northern Mexico, from Ciudad Juarez to the Pacific Ocean. Into their ranks were drawn many soldiers of fortune from the United States, as well as from Europe. A part of these men were no doubt really patriotic in their motives, while others simply grasped the chance of engaging in an exciting campaign because of the freedom of action which was offered, and also partly because of the rewards that were promised by those at the head of the revolution. An eye-witness of the engagement at Tia Juana says that not over ten per cent. of the insurrectos who captured that town were Mexicans, the remainder being made up of Americans, including some negroes, Germans, English and other nationalities. This engagement occurred on May 8th and 9th, 1911. The Federals threw up breastworks of bags of sand, and the women and children were sent out of town to the American side. The fighting was severe and many were killed on both sides. On the second day the government forces yielded, and the rebels immediately pillaged the town and stores. Most of the engagements took place at towns near the border, at Ciudad Juarez, Nogales and Douglass, as well as Tia Juana. Two reasons were probably responsible for this fact. One was that it gave the insurrectos, in case they were defeated, an easy escape across the border, and another was that they were anxious to capture the custom-houses in order to secure the revenue from that source. This would also enable them to set up a _de facto_ government, which might secure for them recognition from countries that looked upon them with favour. Because of these fights on the border, and the reckless shooting by the combatants, no fewer than twenty citizens of the United States were killed and twice that number wounded upon the American side, including men, women and children, none of whom had taken any part in the conflict. The camps of the Maderistas at all times contained numerous American correspondents, and the reports of the majority of them were favourable to the cause of that faction. The battle of Casas Grandes was all but decisive. In this engagement Madero took part and was slightly wounded, while the opposing leader lost an arm. But Madero was soon in the field again at the head of his forces. The movement had likewise spread, and the government faced trouble in the country even as far south as the Isthmus of Tehuantepec.
