The USS Octorara was a double-ended, side-wheel steamer built at the Brooklyn Navy Yard, launched on December 7, 1861, and commissioned on February 28, 1862, under the command of Lt. George Brown. Designed for Union naval service during the American Civil War, she was primarily employed to patrol navigable waterways of the Confederacy, aiming to prevent Confederate trade with foreign nations. Constructed as a steam-powered vessel with a distinctive double-ended hull and side-wheel propulsion, the Octorara was well-suited for blockade duty. She departed New York City on March 17, 1862, initially serving with the North Atlantic Blockading Squadron before joining Commander David D. Porter's forces at Ship Island, Mississippi. Notably, she acted as the flagship for Porter's Mortar Flotilla during the pivotal expedition up the Mississippi River to attack Vicksburg, Mississippi. During the assault on June 28, 1862, she participated in shelling Confederate batteries, although her wheel ropes jammed during the battle, rendering her uncontrollable and causing her to drift into USS Brooklyn's line of fire, resulting in shell damage. On July 24, 1862, while en route to Baltimore for repairs, Octorara captured the British blockade runner Tubal Cain east of Savannah, Georgia, attempting to reach Charleston with munitions. By September 1862, under Commander Napoleon Collins, she rejoined active duty with a "flying squadron" tasked with hunting Confederate and British blockade runners, capturing nine vessels during this period. Later, she joined the West Gulf Blockading Squadron, arriving in New Orleans in October 1863. She contributed to the blockade of Mobile, Alabama, and participated prominently in the Battle of Mobile Bay on August 5, 1864. During the engagement, she passed Fort Morgan with Farragut's squadron, which successfully captured Confederate ships including the CSS Tennessee and CSS Selma. Octorara sustained 17 hits, with one crew member killed and ten wounded, during this fierce engagement. Following the war, she continued operations around Mobile until July 1865, participating in the city's capture on April 12, 1865. Decommissioned on August 5, 1865, she was sold in November 1866. The USS Octorara's service exemplifies her role in key naval operations of the Civil War, showcasing her as a vital vessel in Union blockading and riverine campaigns.
