THE CRUSHING OF OPPOSITION PARTIES
173
Such was the "Rebellion of Las Vacas," as it has come to be known both in the United States and Mexico. As a result of this rebellion and the previous one, the Mexican agents in the United States at last succeeded in breaking up the Liberal organization here almost as effectively as it was broken up in Mexico. Up to the time of the Congressional hearing on the persecutions in June, 1910, all the Liberal leaders in the United States were either in prison or in hiding, and no Mexican dared openly espouse the cause of the Liberal Party for fear that he, too, might be thrown behind the bars on a charge of having been in some way connected with one of those rebellions.
