USS Cambridge
Cambridge — an armed steamer — was built in 1860 by Paul Curtis, Medford, Massachusetts; purchased at Boston, Massachusetts on 30 July 1861; and commissioned on 29 August 1861, Commander W. A. Parker in command. She was outfitted as a gunboat, with two powerful 8 in (203 mm) rifled guns, and assigned to the blockade of ports and waterways of the Confederate States of America.
Assigned to the North Atlantic Blockading Squadron from 9 September 1861 – 5 October 1864, and to the South Atlantic Blockading Squadron from 9 February 1865 until the close of the war, Cambridge helped tighten the stranglehold on the Confederacy as she cruised off the coasts of Virginia and North Carolina and South Carolina. Determined vigilance and alert action won her 11 prizes, some of them taken under the guns of Confederate shore batteries. In a brief five days, she and two other ships in company took four blockade runners, and chased a fifth ashore.
