I have read it. I'm merely pointing out that it was Southerners and Democrats who were primarily responsible for those failures on the part of the federal government. Texas's issue was with herself and her fellow southern states.
If you've read it then you failed to understand it. Texas makes it clear that the federal government mostly in the hands of her "sectional enemies" failed to protect the border and failed to protect against Indian raids AND that they did so out of malice.
