For a while in 1860, Lee stayed at Ringgold Barracks at present day Rio Grande City. Ringgold Barracks was named after Major Ringgold, mentioned in your history of the Mexican War in the Valley.
My great-great-grandfather was stationed at Ringgold Barracks in 1864-65 while in the Confederate Army under Colonel RIP Ford. My ancestor's unit fought Cortina in 1864, as well as Federal troops on the coast.
RIP Ford was something else. While leading a Ranger Company in 1859 and again in the Civil War, he went across the Rio Grande in pursuit of Mexican invaders and defeated them on their own soil.
Too bad we don't have men who are willing to do that today.
Thanks for the links and background on the "Cortina War". I seem to recall some border problems in the early 1900's with Pancho Villa.
I guess every once in a while we need to show Mexico that we do have a border.
