DECEMBER 9TH, 1864: The USS Ostego sank in the Roanoke River near Jamesville, North Carolina, after striking two torpedoes in quick succession. The double-ended Ostego, along with the USS Wyalusing, Valley City and tugs Belle and Bazely had formed an expedition to capture Rainbow Bluff on the Roanoke River, and to investigate the Confederate ram reported to be building at Halifax.
Commander Macomb anchored his squadron at Jamesville to await the arrival of cooperating Union troops and the Ostego struck two torpedoes while anchoring.
The Bazely came alongside to lend assistance and also struck a torpedo and sank instantly.
Lt. Cmdr. Arnold and part of his crew remained on board the sunken Ostego to cover that portion of the river with the guns remaining above water on the hurricane deck.
The resrt of the group moved upriver, dragging for torpedoes, to commence their attack on Rainbow Bluff which took place December 20th.
