Union Blockade - Impact On The Confederacy

Impact On The Confederacy

The Union blockade was a powerful weapon that eventually ruined the Southern economy, at the cost of very few lives. The measure of the blockade's success was not the few ships that slipped through, but the thousands that never tried it. Ordinary freighters had no reasonable hope of evading the blockade and stopped calling at Southern ports. The interdiction of coastal traffic meant that long-distance travel depended on the rickety railroad system, which never overcame the devastating impact of the blockade. Throughout the war, the South produced enough food for civilians and soldiers, but it had growing difficulty in moving surpluses to areas of scarcity and famine. Lee's army, at the end of the supply line, nearly always was short of supplies as the war progressed into its final two years.

When the blockade began in 1861, it was only partially effective. It has been estimated that only one in ten ships trying to evade the blockade were intercepted. However, the Union Navy gradually increased in size throughout the war, and was able to drastically reduce shipments into Confederate ports. By 1864, one in every three ships attempting to run the blockade were being intercepted.

The blockade almost totally choked off Southern cotton exports, which the Confederacy depended on for hard currency. Cotton exports fell 95%, from 10 million bales in the three years prior to the war to just 500,000 bales during the blockade period. The blockade also largely reduced imports of food, medicine, war materials, manufactured goods, and luxury items, resulting in severe shortages and inflation. Shortages of bread lead to occasional bread riots in Richmond and other cities, showing that patriotism was not sufficient to satisfy the demands of housewives. Land routes remained open for cattle drovers, but after the Union seized control of the Mississippi River in summer 1863, it became impossible to ship horses, cattle and swine from Texas and Arkansas to the eastern Confederacy. The blockade was a triumph of the U.S. Navy and a major factor in winning the war.
