High Quality Content by WIKIPEDIA articles! USS Augusta Dinsmore (1863) was a steamer acquired by the Union Navy during the American Civil War. She was used by the Union Navy as a gunboat in support of the Union naval blockade of Confederate waterways. Because of her relatively large size, she was also sometimes used as a cargo ship. By February 1863, Augusta Dinsmore -- a screw steamer completed in 1863 at Mystic, Connecticut -- was operating for the Adams Express Company, moving up and down the Atlantic coast between Northern ports and the Union Navy's blockaders off Charleston, South Carolina, engaged primarily in carrying mail, passengers, and supplies to and from the South Atlantic Blockading Squadron.
