The USS Ella was a wooden-hulled sidewheel steamboat constructed in 1859 in New York by Thomas Collyer for the Stamford Line of Stamford, Connecticut. She measured approximately 150 feet (46 meters) in length, with a beam of 23 feet (7.0 meters) and a hold depth of 8 feet 6 inches (2.59 meters). Powered by a single-cylinder steam engine built by Henry Esler & Co. of New York, her engine had a bore of 36 inches (91 centimeters) and a stroke of 8 feet (2.4 meters). Ella's design featured side paddle wheels, typical of steamboats of her era, making her suitable for both passenger and cargo transport. Ella's initial service began with her maiden voyage on July 5, 1859, operating daily between New York City and Stamford. She departed Stamford at 7 a.m. and returned from New York at 3 p.m., serving as a reliable regional vessel for several years. Her operational routine was interrupted by her acquisition by the Union Navy during the American Civil War, when she was purchased in New York City on July 30, 1862. After outfitting at the New York Navy Yard, she was commissioned on August 10, 1862, under Acting Master S. C. Gray. During her military service, USS Ella was assigned to the Potomac Flotilla, arriving at Fortress Monroe on August 12, 1862. She performed vital roles as a picket, patrol, and dispatch boat along Confederate waterways, primarily operating out of Washington, D.C. Her service was concentrated in Virginia waters, where her small size and maneuverability made her effective in surveillance and communication duties for the Union forces. Ella continued her naval service until July 30, 1865, returning to her base for the last time. She was decommissioned on August 4, 1865, and sold on September 15, 1865. Subsequently, she was redocumented as a merchant steamer on October 19, 1865. Her later history remains obscure, with the last known documentation of her existence dating around 1875. The USS Ella's service exemplifies the versatile use of civilian steamboats adapted for military purposes during the Civil War, highlighting her significance in Union naval operations.
