The Second Battle of Sabine Pass (September 8, 1863) 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. It has often been credited as the war's most one-sided Confederate victory. Confederate President Jefferson Davis wrote in 1876 that he "considered the [second] battle of Sabine pass the most remarkable in military history."
