Assigned to the North Atlantic Blockade
Penobscot, built in ninety days by C.P. Carter, Belfast, Maine, was launched 19 November 1861 and delivered to the Navy at Boston, Massachusetts, 16 January 1862. Assigned initially to the North Atlantic Blockading Squadron, Penobscot destroyed her first Confederate vessel, the schooner Sereta, grounded and abandoned off Shallotte Inlet, North Carolina, 8 June 1862.
On 1 August she seized sloop Lizzie off New Inlet and on 22 October British brig Robert Burns off Cape Fear. Again off Shallotte Inlet 3 November, she forced the British ship Pathfinder aground, then destroyed her. On 22 May 1863 she pursued a Confederate steamer trying to run the blockade near Fort Fisher, North Carolina. One shell reached the ship and crashed into the stateroom of the Surgeon, Dr. Edward Pierson of New Jersey . A splinter of wood fractured the doctor's occipital bone and he died two hours later. Continuing her patrol of the Carolina coast into the summer of 1863, she forced blockade runner Kate ashore at Smith’s Island 12 July.
Gulf of Mexico operations
Shifted then to the Gulf of Mexico, Penobscot joined the blockade ships cruising off the Texas coast. In early January 1864, she provided support for troops landed on the Matagorda Peninsula on 31 December. On 28 February she seized Lilly, a British schooner attempting to run the blockade at Velasco, Texas, to deliver her cargo of powder, and the next day captured schooners Stingray and John Douglas, outward bound with cargoes of cotton. On 12 July, off Galveston, Texas, the “ninety-day” gunboat intercepted the schooner James Williams with a cargo of medicine, coffee, and liquor.
Penobscot’s final operations of the war
By 1865 the Union stranglehold had achieved its purpose. The South was suffering for the materials necessary to wage war. On 18 February Penobscot made her last interceptions. She forced the schooners Mary Agnes and Louisa ashore at Aransas Pass and on the 19th sent a boat crew to destroy them.
