On October 4, 1862, during the American Civil War the Union launched an offensive against Galveston. Union Naval forces capture Galveston in what became known as the Battle of Galveston Harbor.
This victory allowed the Union to control a vital entry point along the Texas coastline, impacting Confederate supply lines and disrupting regional trade. However, Galveston’s occupation was short-lived. Recognizing the city’s importance, Confederate Major General John B. Magruder devised a bold plan to reclaim Galveston.
On January 1, 1863, under cover of darkness, Confederate forces launched a surprise attack by land and water, using “cottonclads”—steam-powered ships reinforced with cotton bales—to engage the Union fleet.
This unconventional tactic allowed the Confederate forces to board and overpower Union ships, effectively retaking the city. The Confederate recapture of Galveston not only boosted Southern morale but also demonstrated the Confederacy’s resolve to defend key strongholds.
The port remained under Confederate control for the rest of the war, cementing its place as one of the few Confederate victories in the region.
