Texas Governor Sam Houston was a staunch Unionist and opposed secession. Despite his objections, on February 1, 1861, Texas became the seventh state to secede from the Union when a state convention voted 166 to 8 in favor of the measure. Houston grumbled that Texans were “stilling the voice of reason,” and he predicted an “ignoble defeat” for the South. He refused to take an oath of allegiance to the Confederacy and was replaced in March 1861 by his lieutenant governor.
Houston had warned that the day that produces a dissolution of this Union will be written in the blood of humanity. He had said: "I wish no prouder epitaph to mark the board or slab that may lie on my tomb than this: 'He loved his country, he was a patriot; he was devoted to the Union.'.
