The Battle of Galveston was a naval and land battle of the American Civil War, when Confederate forces under Major Gen. John B. Magruder expelled occupying Union troops from the city of Galveston, Texas on January 1, 1863.

John Bankhead Magruder was an American and Confederate military officer. A graduate of West Point, Magruder served with distinction during the Mexican–American War (1846–1848) and was a prominent Confederate Army general during the American Civil War (1861–1865). As a major general, he received recognition for delaying the advance of Maj. Gen. George B. McClellan's large force, the Army of the Potomac, during the 1862 Peninsula Campaign, as well as recapturing Galveston, Texas the following year.
