During the war the commanders of the Navy’s operating squadrons provided periodic reports on the assignments of vessels in their respective commands. Rear-Admiral John Dahlgren did so twice a month (with some variance, but more or less on the 1st and 15th of each month). As was the practice, he submitted a report on January 1, 1865. The report was the first since the fall of Savannah. So there were adjustments due to the changing situation and mission. Obviously, with no need to blockade Savannah and no threat from rams from that port, Dahlgren could reallocate his forces. Considering the operations that followed in the first months of 1865, it’s worth a look at the Navy’s dispositions on the first day of the year.
The first grouping to look at is the area from the South Carolina border to Charleston:
As of January 1, no vessel patrolled Murrell’s Inlet. The furthest north assignment was the steamer USS Canadaigua covering Winyah Bay, approaches to Georgetown, and Cape Romain. The sailing vessels USS George Mangham and USS James S. Chambers covered Bull’s Bay. Of course, north of the state line was the jurisdiction of the North Atlantic Blockading Squadron. There was a significant naval force operating off Cape Fear against the Confederate defenses there. But that falls outside the scope of my post.
Laying outside the bar of Charleston, the blockade consisted of the steamers USS James Adger, USS Wamsutta, USS Nipsic, USS Mary Sanford, USS South Carolina, USS Flambeau, USS Memphis, and USS Potomska. The tugs USS Laburnum, USS Azalea, and USS Sweet Brier also operated outside the bar. These vessels formed the primary force to intercept blockade runners inbound to Charleston.
Inside the bar, with the mission to block either runners or rams from exiting the harbor, was the strongest elements of the squadron. This force included seven monitors – USS Patapsco, USS Montauk, USS Nahant, USS Passaic, USS Nantucket, USS Lehigh, and USS Catskill (under repairs). The tugs USS Gladiolus, USS Catalpa, USS Hydrangea, USS Jonquil, USS Geranium, and USS Oleander supported the monitors and patrolled the ship channels. Other vessels inside the bar off Charleston were the sailing vessels USS John Adams, USS Orvetta, USS Sarah Bruen, and USS Sea Foam. The tender USS Home was also in the waters off Morris Island.
Also off Morris Island, but operating in support of the Army, were the gunboats USS Wissahickon and USS Commodore McDonough, along with the mortar schooners (abbreviated M.S. for my map) USS T.A. Ward, USS Dan Smith, and USS C.P. Williams.:
South of Charleston, several vessels covered the waterways of South Carolina. The sailing ship USS St. Louis covered the North Edisto. The gunboat USS Stettin and schooner USS Norfolk Packet covered St. Helena Sound.
At Port Royal were the steamers USS Philadelphia and USS Pawnee; the tugs USS Arethusa, USS Carnation, USS Larkspur, and USS O.M. Pettit; and the sailing vessel USS Houghton. In addition the steamers USS Mingoe and USS Pontiac, along with tugs USS Daffodil and USS Dandelion, were operating up the Broad River in direct support of Army operations there. Other vessels listed at Port Royal were tenders and hulks, which included the old ship of the line USS New Hampshire and the old blockade runner USS Chatham.
Also at Port Royal, but not available due to servicing and repairs (and thus not tallied on my maps), were the monitor USS Sangamon; steamers USS Cimarron, USS Ottawa, and USS Winona; tugs USS Acacia, USS Amaranthus, USS Iris, USS Camelia, and USS Clover; and the sailing ships USS Braziliera and USS George W. Rogers.
Covering the coast of Georgia, the squadron was now able to spread itself thin:
Posted to the Savannah River was the steamer USS Sonoma and mortar schooner USS Racer. The mortar schooner USS John Griffin was posted to Wassaw Sound. The steamer USS Flag and mortar schooner USS Para policed the waters of Ossabow Sound. The bark USS Fernandina covered St. Catherine’s Sound. The steamer USS Lodona‘s assignment was Sapelo Sound. The USS Saratoga was in Doboy Sound. The bark USS Ethan Allen plyed the waters off St. Simon’s Island. And the USS Dai Ching covered St. Andrew’s Sound. The latter vessel, one of Dahlgren’s light draft steamers, was due to move north and cover South Carolina waters.
The brig USS Perry provided support to Army posts at Fernandina, Florida. further south in Florida (and off my map), the steamers USS Norwich and USS E.B. Hale operated in the St. Johns River.
Add to these forces the various armed transports operated by the Army, for whom there is scant accounting in the official records. All considered, a formidable force ranging from ironclads to armed tugs confronted the Confederate forces along the southern Atlantic coastline.
NOTE: Several of the sailing vessels had been rated as mortar schooners earlier in the war. In some cases, with the mortars removed, those vessels served as blockaders. I’ve tallied those former mortar schooners as sailing blockaders for this post. So if you sense there is some mis-match of the ratings, keep that in mind.
