American Civil War: In the Second Battle of Sabine Pass, a small Confederate force thwarts a Union invasion of Texas.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.

The Second Battle of Sabine Pass was a failed Union Army attempt to invade the Confederate state of Texas during the American Civil War. The Union Navy supported the effort and lost three gunboats during the battle, two captured and one destroyed.
