CSS Alabama
CSS Alabama was a screw sloop-of-war commissioned into the Confederate States Navy in 1862, constructed clandestinely at the John Laird and Sons shipyard in Birkenhead, England, for commerce raiding against United States shipping during the American Civil War.[1][2] Commanded by Captain Raphael Semmes, a veteran Confederate naval officer, Alabama embarked on a global cruise spanning 75,000 nautical miles across the Atlantic, Indian, and Pacific Oceans.[3][4] Over nearly two years of operations from August 1862 to June 1864, Alabama captured or bonded 65 Union merchant vessels and whalers, burning most to deny their use to the Northern economy and war effort, making her the most successful Confederate raider in terms of prizes taken.[5][6] Her tactics emphasized speed, surprise, and the use of disguise, avoiding prolonged engagements with Union warships until her final battle.[1] Alabama's career ended on June 19, 1864, when Semmes challenged the USS Kearsarge to combat off Cherbourg, France, resulting in Alabama's rapid sinking after a fierce hour-long exchange of broadsides, with Semmes' crew suffering heavy casualties and many survivors rescued by nearby vessels.[7][5] The ship's construction in British yards despite official neutrality sparked the Alabama Claims, a major diplomatic dispute resolved by international arbitration in 1872, in which Britain paid the United States $15.5 million in compensation for Alabama's depredations and similar raiders.[8] This outcome reinforced principles of neutrality and due diligence in maritime law, influencing future international relations.[8]Design and Construction
Technical Specifications
The CSS Alabama was a wooden-hulled, screw sloop-of-war with barkentine rigging, designed for speed and long-range cruising as a commerce raider. Her hull was constructed of oak and teak, copper-sheathed for protection against marine growth, enabling extended operations without frequent docking.[9] Key dimensions included a length overall of 213 feet 8 inches, an extreme beam of 32 feet, a depth of hold of 18 feet, and a fully loaded draft of 15 feet. Displacement reached 1,438 tons when fully loaded.[9] Alternative measurements cite a deck length of 220 feet with the same beam and loaded draft.[3] Propulsion combined sail and steam power. She featured two direct-acting, horizontal condensing engines with twin cylinders, rated at 300 horsepower total, driving a single lifting screw propeller that could be hoisted clear of the water for sailing efficiency. Four boilers supported steam operations, with a coal capacity of 285 tons allowing for extended voyages. Under steam alone, she achieved about 10 knots; combined sail and steam yielded up to 13 knots, with a designed maximum of 12 knots and ordinary service speed of 10 knots.[9][3]| Category | Details |
