Aransas Pass, C.S.A.
Port Aransas, Nueces County, Texas
Marker Inscription
Aransas Pass, the natural inlet (3 miles east) to Aransas Bay, separates San Jose and Mustang Islands. These islands are part of a chain of barrier islands which extend along the entire length of Texas' Coastal Mainland. At the beginning of the civil war countless small vessels transported confederate supplies up and down the Texas and northern Mexican Coast virtually undisturbed by federal naval forces. Cotton destined for foreign markets moved freely through Aransas Pass. By early 1861 a union blockade had halted trafficking by confederate vessels beyond the barrier islands. However, confederate supplies inside the barrier chain continued and inlets such as Aransas Pass became sites of increasingly strategic military value. The Aransas Pass area came under the control of Federal Captain J.W. Kittredge's Naval Forces until his capture in September 1862. In November 1863 a massive federal force gained control of the south Texas Coast from the Rio Grande to Matagorda Bay. Eventually, Federal Forces lost control of the mainland behind Aransas Pass and in June 1864 withdrew from the area. Afterward, confederate ships successfully eluded the federal blockade and delivered vital supplies to the confederacy by way of Aransas Pass. Sesquicentennial of Texas Statehood 1845-1995.

The Story
Aransas Pass, the natural inlet separating San Jose and Mustang Islands, became a strategically vital point along the Texas coast during the Civil War. Early on, Confederate vessels moved cotton and supplies freely through the pass, but a Union blockade soon tightened, and Federal forces under Captain J. W. Kittredge seized control until his capture in 1862. Control seesawed through 1863 and 1864, and after Union forces withdrew, Confederate ships again slipped supplies through the pass to sustain the wartime South.
Why it matters
The struggle over Aransas Pass shows how the Union blockade turned obscure coastal inlets into contested lifelines in the Confederacy's fight to keep trading with the world.
The story behind this marker
AI contextThe era
Aransas Pass is a natural break in the long chain of barrier islands that shields the Texas coast, the inlet that separates San Jose and Mustang Islands and opens the way into Aransas Bay. In the age of sail and shallow-draft steamers, such a pass was not scenery — it was infrastructure, one of the few doorways between the open Gulf and the sheltered water behind the islands.
When the Civil War began in 1861, that geography suddenly carried enormous strategic weight. The Confederacy's great export was cotton, and its lifeline was the ability to trade that cotton abroad for the manufactured goods and munitions it could not make itself. Along the Texas and northern Mexican coast, small vessels moved supplies almost at will in the war's opening months.
Then came the Union blockade. Washington's strategy was to strangle Southern commerce by sealing its ports, and by early 1861 that pressure had begun to halt Confederate traffic beyond the barrier islands — turning quiet coastal inlets like Aransas Pass into contested ground.
People & events
The war's tug-of-war along this coast plays out vividly in the marker's account. Inside the protective chain of islands, Confederate supply traffic kept moving even as the blockade tightened offshore, and every usable inlet became a prize worth fighting for.
Control of the Aransas Pass area fell for a time to Federal naval forces under Captain J. W. Kittredge, whose command over the inlet lasted until his capture in September 1862 — a sharp reversal that shows how fluid and personal these coastal contests could be. The larger blow came in November 1863, when a massive Federal push seized the south Texas coast from the Rio Grande all the way to Matagorda Bay.
But holding a coastline is harder than taking it. By June 1864, Federal forces had lost their grip on the mainland behind Aransas Pass and withdrew from the area. In the aftermath, Confederate ships once again slipped past the blockade through the pass, carrying in the vital supplies that kept the wartime South resisting. The marker was placed for the Sesquicentennial of Texas Statehood, 1845–1995.
Its place in the American story
The Union blockade is one of the defining strategies of the Civil War, and Aransas Pass shows exactly how it worked — and where it leaked. The blockade was never a solid wall; it was a stretched cordon, and its effectiveness rose and fell inlet by inlet, month by month.
Here on the Texas coast, far from the war's famous battlefields, the outcome still mattered to the whole Confederate cause. Cotton run out through passes like this one paid for the imported arms and goods the South depended on, so the seesaw of control at an obscure Gulf inlet was directly tied to the Confederacy's ability to keep fighting.
The pass also illustrates a hard truth of the war at sea: the North could concentrate overwhelming force to seize a coastline, as it did in late 1863, yet still fail to hold it against a determined and geographically favored defense. That the Confederacy resumed blockade-running here in 1864 is a reminder of how contested, and how consequential, these forgotten coastal margins remained until the very end.
If you visit
You'll find this story on the coast at Port Aransas, where the marker points you toward the natural inlet a few miles to the east. The pass itself is the real monument — stand where the Gulf meets the gap between the barrier islands and you're looking at the same strategic doorway that fleets fought to control.
Let the setting do the historical work. The barrier islands still run the length of the Texas coast exactly as the inscription describes, and it takes little imagination to picture shallow-draft blockade-runners threading the inlet under cover of darkness while Federal warships patrolled offshore. The wind, the shifting sand, and the open water are the same conditions that made this place so hard to hold.
It's an easy addition to a coastal trip built around beaches, birding, and the ferry crossings of the region. Read the marker with the water in view, and an ordinary stretch of Gulf shoreline turns into a front line of the Civil War.

Aransas Pass Light Station
Port Aransas, TX
Begun in 1855 and first lit in 1856, this 67-foot tower with its imported French lens marked the natural Gulf pass to Aransas and Corpus Christi Bays. During the Civil War, Confederates buried the lens and damaged the tower in 1863 to keep its light from aiding Federal forces. Rebuilt after the 1919 hurricane, it was finally decommissioned in 1952 once the shifting pass moved south of it.
Site of the Corpus Christi Lighthouse
Corpus Christi, TX
As Corpus Christi worked to become a deepwater port in the late 1850s, the U.S. Lighthouse Service bought this site in 1857 and built a brick lighthouse to guide approaching vessels. The Civil War halted the harbor plans, and Confederate forces turned the tower into a powder magazine — until a band of young Confederate loyalists, fearing Federal capture in 1863, secretly packed a butter churn with gunpowder and tried to blow it up. The blast scorched the tower but spared the powder store; the battered beacon limped on until it was dismantled as a nuisance around 1878.
U.S. Coast Guard on Mustang Island
Port Aransas, TX
To tame the treacherous Aransas Pass, the government established the first Aransas Life Saving Station on Mustang Island in 1878; when the 1919 hurricane destroyed it, successors carried on the work into the modern era. Woodrow Wilson's 1915 merger of the Revenue Cutter and Life Saving services created the U.S. Coast Guard, whose Mustang Island duties expanded from rescue to hunting enemy saboteurs with canine beach patrols in World War II and, later, to escorting military cargo and inspecting vessels in the War on Terror.
Mustang Island
Port Aransas, TX
Mustang Island, one of seven Texas barrier islands, took its name from the wild horses descended from shipwrecks and Spanish expeditions, and was long frequented by the nomadic Karankawas. Robert Ainsworth Mercer settled here in 1855 with his family, founding the El Mar Rancho, but the small community scattered during the Civil War when the USS Arthur blockaded Aransas Pass and shelled the island after settlers fired on Federal sailors in 1862. Ranchers returned after the war, and by the 1920s tourism had become the island's economic mainstay.
