A central tenet of the nascent Confederate Navy’s strategy during the American Civil War was to make Yankee merchants howl from the loss of their vessels and cargos. In order to achieve this aim, the Confederates commandeered suitable vessels in Southern ports to convert to armed merchant raiders, issued letters of marque and reprisal and procured vessels abroad. Because the Confederacy was not recognized as a sovereign nation by Great Britain or France, the ships procured or built there had to be built ostensibly as merchant vessels and later outfitted with armaments after leaving British territorial waters. Among the ships acquired by Confederate agent James Bulloch was the steamer Sea King.
Launched in Glasgow in August 1863, the Sea King was a 1,160 ton steamer equipped with auxiliary sails. After being purchased by Bulloch, the Sea King put to sea in October and rendezvoused with another ship off Madeira. On October 19, 1863 after several days of transfering cargo and mounting her guns, the Sea King was commissioned as CSS Shenandoah after the beautiful and bountiful Virginia valley. The ship’s design was perfect for raiding merchant vessels as she could raise and lower her steam funnel at will in order to change her identity from steam vessel to sailing vessel.
From the Madeiras, the Shenandoah and her new captain, commander James Iredell Waddell sailed through the South Atlantic to the Indian Ocean and captured nine US vessels. Shenandoah called at Melbourne, Australia where she re-provisioned and added forty more men to her crew. After departing Melbourne, Shenandoah ravaged her way north through the Pacific Ocean capturing four more Yankee vessels en route to the lucrative North Pacific whaling fleet. Unbeknownst to the Shenandoah and her crew, the Confederacy had effectively collapsed with Robert E. Lee’s surrender at Appomattox Courthouse on April 9. The news, though, would not reach the Shenandoah until after she had wreaked havoc among the American whaling fleet, capturing 24 ships in a period of 7 days from June 22 to June 28, 1865.
After learning of the Confederacy’s surrender on August 2 from newspapers aboard an English merchantman, Waddell successfully returned his ship to Liverpool where he struck the Confederate naval ensign and turned her over to the Royal Navy. An excellent account of the voyage, Last Flag Down, was published in 2007 by a descendant of one of the Shenandoah’s officers.
