Geranium, formerly John A. Dix, was built at Newburgh, N.Y., in 1863; purchased by the Navy at New York City 5 September 1863; and commissioned at New York Navy Yard 15 October 1863, Acting Ens. G. A. Winsor in command.
Geranium departed New York 20 October for duty off Charleston, S.C., with Rear Admiral J. A. Dahlgren's South Atlantic Blockading Squadron. Arriving 4 November, for the next 6 months she operated as a picket boat and was frequently employed as a dispatch boat and light transport to such diverse stations as Ossabaw Sound, S.C., and St. John's River, Fla. Occasionally she transported Admiral Dahlgren during visits to various ships of his squadron
Between 3 and 10 July 1864, Geranium participated in a diversionary expedition up the Stono and North Edisto Rivers south of Charleston to divert Confederate attention from the Charleston blockade and to cut the important Charleston and Savannah Railroad. She supported the movement of troops under General Birney up the North Edisto River, towing and transporting supplies for the expedition. On 3 July she contacted and engaged a strong Confederate battery at the mouth of the Dawhoo River, a bombardment which Admiral Dahlgren reported was "done very handsomely." After completing demonstration operations, she supported the withdrawal of Federal troops from the tidewater island South of Charleston.
Continuing her picket, dispatch, and transport duties from 12 to 17 February 1865, Geranium participated in joint Army-Navy operations at Bull's Bay north of Charleston, and on the 16th and 17th she supported diversionary amphibious landings which hastened the Confederate evacuation of Charleston the following day. Admiral Dahlgren then ordered her to the mouth of the Santee River, where she supported naval operations against Georgetown, S.C., before departing 28 February on a reconnaissance mission up the Santee. With launches Lilly and Eva in tow she ascended as far as Black Oak Island and gained valuable information about the depth and navigability of the river. As a result of this intelligence, General Sherman's troops could be supplied from transports on the Santee rather than solely by railroad.
