Atlantic Blockading Squadron

Atlantic Blockading Squadron. It was a major United States Navy formation established during the American Civil War to enforce the Union blockade along the Atlantic coast of the Confederate States of America. Its primary mission was to cripple the Confederate economy by preventing the export of cotton and the import of vital war materiel. The squadron's operations were a critical component of General Winfield Scott's Anaconda Plan, aiming to strangle the Confederacy through naval power.

Formation and purpose

The squadron was officially created by an order from the U.S. Navy Department on May 17, 1861, following President Abraham Lincoln's proclamation of a blockade in April. Its strategic purpose was to seal off major Confederate ports from Chesapeake Bay to Key West, though its boundaries were later adjusted. This naval effort was designed to isolate the Confederacy from international recognition and support, particularly from Great Britain and France, by intercepting blockade runners. The immense geographic responsibility underscored the Union Navy's rapid wartime expansion and the logistical challenges of sustaining a close blockade over thousands of miles of coastline.

Command and organization

Initial command was given to Flag Officer Silas H. Stringham, a veteran of the War of 1812 and the Mexican–American War. In September 1861, he was succeeded by Flag Officer Louis M. Goldsborough, who commanded during several key amphibious operations. In September 1862, command passed to Rear Admiral Samuel Phillips Lee, a relative of Robert E. Lee, who led the squadron for most of the war. The squadron was administratively divided into the North Atlantic Blockading Squadron and the South Atlantic Blockading Squadron in October 1861 to improve efficiency, with the dividing line set at the border between North Carolina and South Carolina. This reorganization allowed for more focused operations against critical ports like Wilmington and Charleston.

Major engagements and operations

The squadron saw immediate action, with Stringham leading a successful amphibious assault against Fort Clark and Fort Hatteras in the Battle of Hatteras Inlet Batteries in August 1861, providing the Union its first significant victory. Under Goldsborough, it supported the massive joint expedition that captured Port Royal Sound, establishing a crucial coaling and repair station. In early 1862, the squadron played a pivotal role in Ambrose Burnside's Burnside's North Carolina Expedition, culminating in the Battle of Roanoke Island. Its vessels were also central to the historic Battle of Hampton Roads, where the USS Monitor fought the CSS Virginia. Later, it maintained constant pressure on the Fort Fisher defenses guarding Wilmington, the Confederacy's last major open port.

Vessels and logistics

The squadron comprised a diverse and evolving fleet, from aging sailing frigates and converted merchant ships to modern ironclads like the USS Monitor and purpose-built gunboats such as the USS Mahaska. Steam power was essential for maintaining station against winds and currents. Logistics were monumental, requiring a network of coaling stations, supply depots, and repair facilities at captured points like Port Royal and Hampton Roads. The presence of hospital ships and colliers was vital for sustained operations. The squadron also increasingly incorporated captured blockade runners into its own forces, turning the Confederacy's tools against it.

Impact and legacy

The squadron's relentless pressure severely degraded the Confederate war effort by drastically reducing the volume of arms, supplies, and revenue reaching Southern shores. While never completely airtight, the blockade raised insurance rates for blockade runners to prohibitive levels and was a decisive factor in the economic collapse of the Confederacy. Its operations demonstrated the effectiveness of naval power in grand strategy and advanced the technology and tactics of coastal warfare and amphibious warfare. The squadron's history is studied as a key chapter in the evolution of the United States Navy into a modern, global force and a foundational element of the Union's ultimate victory in the American Civil War.
