Civil war service
Assigned to the North Atlantic blockade
She was ordered to the York River to support General George B. McClellan's push up the peninsula toward Richmond, Virginia, and operated in that river and its tributaries supporting Union Army operations.
Then, on 30 June, after General Robert E. Lee had defeated McClellan in the Seven Days Campaign and had driven the Army of the Potomac from the York to the James River, Sebago steamed downstream, rounded Old Point Comfort, and ascended the James escorting Army transports.
Reassigned to the South Atlantic blockade
Transferred to the South Atlantic Blockading Squadron later that month, Sebago departed Hampton Roads on 25 July and arrived off Charleston, South Carolina, on the 29th to begin a year of blockade duty off the approaches to that important and historic Southern port.
On 18 June 1863, the double ender ran aground in Wassaw Sound and suffered some damage. As she was due for an overhaul, she sailed north on 29 July and was decommissioned at the New York Navy Yard on 9 July.
Reassigned to the Gulf of Mexico
Repairs and overhaul completed, Sebago was recommissioned on 2 December and sailed for the Gulf of Mexico for duty in the West Gulf Blockading Squadron in which she served through the end of the Civil War.
The highlight of her operations in the gulf came on 5 August 1864, when she participated in the Battle of Mobile Bay.
