The Plan de San Diego: Tejano Rebellion, Mexican Intrigue, based on newly available archival documents, is a revisionist interpretation focusing on both south Texas and Mexico. Charles H. Harris III and Louis R. Sadler argue convincingly that the insurrection in Texas was made possible by support from Mexico when it suited the regime of President Venustiano Carranza, who co-opted and manipulated the plan and its supporters for his own political and diplomatic purposes in support of the Mexican Revolution.
The study examines the papers of August�n Garza, a leading promoter of the plan, as well as recently released and hitherto unexamined archival material from the Federal Bureau of Investigation documenting the day-to-day events of the conflict.
