USS Commodore McDonough was a ferryboat acquired by the Union Navy during the American Civil War. Ferryboats were of great value, since – because of their flat bottom and shallow draft — they could navigate streams and shallow waters that other ships could not.
Purchased in New York City in 1862
Commodore McDonough — an armed, side-wheel ferry — was purchased on 5 August 1862 in New York City; fitted out at New York Navy Yard; and commissioned on 24 November 1862, Lieutenant Commander G. Bacon in command.
At the close of the war, she assisted in harbor clearance at Port Royal, South Carolina, and on 23 August 1865 — while under tow for New York — she foundered.
