USS Brooklyn

C. S. Steamer Sumter, Head Of The Passes,’) June 30, 18G1. j Sir: — I have the honor to inform the Department that I am still at my anchors at the “Head of the Passes” — the enemy closely investing both of the practical outlets. At Pass a L’Outre there are three ships, the Brooklyn, and another propeller, and a large side-wheel steamer; and at the Southwest Pass, there is the Powhatan, lying within half a mile of the bar, and not stirring an inch from her anchors, night or day. I am only surprised that the Brooklyn does’ not come up to this anchorage, which she might easily do — as there is water enough, and no military precautions, whatever, have been taken to hold the position — and thus effectually seal all the passes of the river, by her presence alone; which would enable the enemy to withdraw the remainder of his blockading force, for use elsewhere.

USS Brooklyn (1858) was a sloop-of-war authorized by the U.S. Congress and commissioned in 1859. Brooklyn was active in Caribbean operations until the start of the American Civil War at which time she became an active participant in the Union blockade of the Confederate States of America.
With her one 10-inch gun and twenty 9-inch guns, Brooklyn was a formidable fighting ship that could deliver damaging broadsides, and served on the Atlantic Ocean coast as well as the Gulf Coast of the United States in intercepting blockade runnersBrooklyn also served gallantly attacking Confederate forts and other installations on the Mississippi River.
Post-war, Brooklyn remained active, serving for some years in the European theatre, as well as circumnavigating the globe. She was retired in 1889 and sold in 1890 after having well served her country for over three decades.
