Dahlgren's Ships

Does anyone know what ships to link to this article? This picture for example dates from 1864, I think. It commemorates what was then regarded as an important event, and the pivot point of the U.S Military creating and using Signals Corps. for wider use in Army and Navy. Part of the caption for it reads This photograph shows a party of Admiral John A. Dahlgrens signal-men on board ship receiving a message from the Georgia shore. The two flagmen are standing at attention, ready to send Dahlgren's answering message, and the officer with the telescope is prepared to read the signals from the shore. Thus Shermans message from the parapet of Fort McAllister was read. Commander C. P. R. Rodgers and Admiral Dupont had been prompt to recognize the value of the Army Signal Corps system and to introduce it in the navy. Possible candidates for the ship shown (Dahlgren's flagship) are the USS Galena (ship, 1880), the USS Wabash (ship, 1861) or even the USRC Nemaha (ship, 1862). I can't ascertain the name of Dahlgren's flagship at the time, can anyone help. There is no mention here of this incident or the names of Dahlgren's flagships.

John A. Dahlgren (November 13, 1809 – July 12, 1870) was a United States Navy officer who founded the Navy's Ordnance Department and launched major advances in gunnery. He introduced a cast-iron muzzle-loading cannon with vastly increased range and accuracy, known as the Dahlgren gun, which became the Navy's standard armament. During the American Civil War, he was made the commander of the Washington Navy Yard. He also served at sea, being put in command of the South Atlantic Blockading Squadron.
