However, some theories state that the true goal of the plan was to create the conditions to force the US to support one of the factions of the Mexican Revolution, as eventually occurred.

The plan called for the killing of all adult White American men in the Southwestern states[1] and the "return of land to Mexicans."

Although there was no large-scale uprising, supporters of the plan initiated the Bandit War, launching raids into Texas that began in July 1915.

On February 20, 1915, the plan was called for starting the execution of "North American" men over the age of 16; only the elderly as well as women and children were to be spared.

[3] The plan was penned in San Diego, Texas, but it was actually signed by rebels inside a jail cell in Monterrey, Mexico.

[4] Ramos credited the creation of the plan to another unnamed Huertista, who hoped to reconquer the Southwestern United States to gain domestic support in Mexico for Huerta.

Another theory states that the Mexican government under Venustiano Carranza, who became president of Mexico in 1914, supported the drafting of the Plan of San Diego in order to exploit the tension between Tejanos and white Americans inside southern Texas.

[4] Some believe that Carranza wanted to exacerbate conflict between Americans and Mexicans in Texas to force the United States to recognize him as the true leader of Mexico, as ultimately happened.

On July 11, at the Magnolia dance ground in Brownsville, raiders shot and killed Tejano deputy Pablo Falcon, the first victim of the Plan of San Diego.

[5] The raids during this period were led by cousins Aniceto Pizana and Luis de la Rosa, well-known residents of South Texas.

Then, Carranza used his armies to assist the Americans in capturing and imprisoning raiders, which ended the high tide of the Plan of San Diego.

[4] Local whites founded the vigilante Law and Order League in 1915, fueled by suspicions of Mexican and Tejano insurrection.

[5] The 1919 Canales investigation into misconduct by the Texas Rangers estimated that from 1914 to 1919, between 300 and 5,000 ethnic Mexicans were killed by American law enforcement personnel engaged in suppressing the raids.
