Panic spread in 1915 when authorities in McAllen, Texas, arrest Basilio Ramos, Jr. Ramos was carrying a copy of the Plan of San Diego, a revolutionary manifesto supposedly written and signed at the South Texas town of San Diego. It called for the formation of a "Liberating Army of Races and Peoples," of Mexican Americans, African Americans, and Japanese, to "free" the states of Texas, New Mexico, Arizona, California, and Colorado from United States. Versions of the plan call for the murder of all white citizens over 16 years of age. The goal was an independent republic, which might later seek annexation to Mexico. Raids from both side the the border quickly escalated into guerilla warfare. Francisco (Pancho) Villa's raid on Columbus, New Mexico, in March 1916, causes more panic and the United States responds by sending a large military force under Gen. John J. Pershing in pursuit of Villa.
Yeah those poor innocent theives and murderers.
On Sept. 30, 1915, Roland Warnok witnessed the murder of two unarmed Tejanos 68-year-old Jesus Bazan and his son-in-law Antonio Longoria by Rangers in a Model T Ford. Bazan and Longoria were shot in the back, off their horses, as the Rangers passed by.
------------------
Note the synchronicity of dates. There was a war taking place in 1915. The Rangers were probably out "Meskin' huntin' " -- and got what they went after.
Ugly times! But it is inappropriate to dredge them up 90 years later and whine about one side of what took place on both sides.
Many white people were killed and many others fled. The insurgents unsuccessfully attempted to rally blacks and American Indians to their side. Ethnic Japanese did help, though. I daresay that that was remembered in 1941 after Pearl Harbor.
There was so much continuing concern about Mexican-"Americans" that in 1930 census ethnic Mexicans were no longer counted as white but as Mexican. Lobbying by Mexican-"Americans" re-established them as white folk the in 1940 census.
