The Cotton Road: Brownsville in the Civil War
Near Brownsville, Texas
By the autumn of eighteen sixty-three, the Port of New York had a problem. Confederate cotton was moving through Brownsville to Matamoros, crossing the Rio Grande onto Mexican soil, and sailing from the river's mouth at Bagdad to European ports on foreign ships that Union warships could not legally stop. Mexico was a neutral country.
The river itself was international. The blockade did not apply. At the height of the Confederate wartime cotton trade, as many as seventy European freighters waited at anchor off the mouth of the Rio Grande, exchanging weapons, medicines, dry goods, and coffee for Texas bales.
Wagon trains a mile long moved cotton east from the interior through Brownsville and across the shallow river ford to Matamoros brokers. Confederate soldiers at Fort Brown were not fighting. They were managing a supply chain.
President Lincoln's advisors understood what was happening. In November of eighteen sixty-three, Union General Nathaniel Banks landed troops on the Texas Gulf coast and marched on Brownsville. Confederate forces evacuated and burned what they could before Union soldiers arrived.
But they could not hold it: Confederate Colonel Rip Ford retook the town in the summer of eighteen sixty-four, and the cotton trade resumed. The Matamoros cotton corridor was ultimately one of the reasons the last battle of the Civil War happened near Brownsville at all, about a month after Lee's surrender. The Confederacy had protected this border crossing until it had nothing left to protect.
A sleepy river town had become, for four years, one of the most strategically important shipping points in North America.
