She was used by the Union Navy first as a dispatch boat, and also as a gunboat assigned to patrol Confederate waterways.
Built in New York City in 1861
Civil War operations
Assigned Potomac River operations
The ferryboat departed New York City on 21 October, served briefly at Hampton Roads, Virginia, reached the Washington Navy Yard on 5 November, and was promptly placed in service as a dispatch boat in the Potomac Flotilla. These first few weeks of her service typified her fortunes throughout the Civil War.
Her services were wanted both in the Potomac Flotilla and in the North Atlantic Blockading Squadron for service along the west coast of the Chesapeake Bay and on the rivers -- roughly parallel to the Potomac -- which drain Tidewater Virginia. As a result, the ferry was shuttled between the two commands as ground operations ebbed and flowed over the Virginia farmlands which separated Washington, D.C., and Virginia.
Operations on the James River in Virginia
During 1863 She was stationed in the Nansemond River and participated in the Siege of Suffolk (VA) undertaken by Longstreet's Corps. One notable event was rescuing, under heavy fire, of USS Mount Washington when that ship had been grounded and disabled during and engagement with an earth works near Suffolk, Virginia. Later, after running the same battery, she made two landings againist the earth works; which fell in an assault by Union Army units supported by the Stepping Stones' boat howitzers. Also notable is her participation in a mid-April 1864 Army-Navy expedition up the Nansemond River.
In May 1864, she became part of a torpedo sweeping (mine sweeping) and patrol force on the James.
Capturing Confederate blockade runners
In March 1865, less than a month before Robert E. Lee surrendered, Stepping Stones was in a naval expedition up Mattox Creek to Colonial Beach, Virginia, where the Union ships attacked a supply base for Confederate guerrillas operating on the peninsula between that river and the Potomac River.
Post-war decommissioning, sale and subsequent civilian career
After the war ended, Stepping Stones was decommissioned at the Washington Navy Yard on 23 June 1865 and was sold on 12 July 1865 to W. D. Wallach. Redocumented as Cambridge on 27 July 1865, the steamer was reduced to a barge on 2 August 1871 and soon disappeared from maritime records.
