She was used by the Union Navy as a gunboat in support of the Union Navy blockade of Confederate waterways. During the war, she participated in the operation of placing a spar torpedo into the dreaded CSS Albemarle, allowing Shamrock to sail on with the Union fleet to attack and capture Plymouth, North Carolina. After the war, she served in the Caribbean and voyaged to Europe prior to final decommissioning.

Shamrock commissioned in New York City on St. Patrick’s Day[edit | edit source]

Shamrock—a double-ended side wheel gunboat built at the New York Navy Yard—was launched on St. Patrick's Day, 17 March 1863; sponsored by. Miss Sallie Bryant, daughter of Mr. William Cullen Bryant; and commissioned on 13 June 1864, Cdr. William H. Macomb in command.

Assigned to the North Atlantic Blockade off North Carolina[edit | edit source]

The next day, Shamrock was ordered to proceed directly to the sounds of North Carolina for duty in that area as part of the North Atlantic Blockading Squadron. At that time, Union naval forces in the sounds were threatened by the Confederate ironclad ram, Albemarle, which in April had sunk Union side wheel steamer, USS Southfield, and had enabled Southern forces to recapture Plymouth, North Carolina.

On the lookout for the Confederate ram CSS Albemarle[edit | edit source]

On the 20th, Shamrock reached Hatteras Inlet where orders awaited her to enter Albemarle Sound and take station off the mouth of the Roanoke River to guard against the reappearance of the formidable Rebel ram. For the next four months, Shamrock's operations concentrated on protecting Union shipping from Albemarle, which was undergoing repairs up the Roanoke River.

Surreptitiously approaching Albemarle and planning to sink her[edit | edit source]

Late in October, Shamrock served as the mother ship of the steam launch which Lt. William Barker Cushing had brought to the sounds from New York City to attack Albemarle. On the night of 27 and 28 October 1864 Cushing and his team began working their way upriver. The small cutter accompanied them, the crew of which had the task of preventing the Confederate sentries stationed on a schooner anchored to the wreck of USS Southfield. Both boats, however, slipped past the schooner undetected, and Cushing decided to use all 22 men to try to capture Albemarle.

Spotted while making their approach to Albemarle[edit | edit source]

As they approached the Confederate docks, though, their luck turned. They were spotted and taken under heavy fire from both the shore and Albemarle. They closed with Albemarle and discovered that she was defended against approach by booms of floating logs. The logs, however, had been in the water for many months and were covered with slime, and the small craft rode over them without difficulty. When the small civilian craft was against the hull of the warship, Cushing stood up in the bow and detonated the explosive charge.

The spar torpedo goes off against Albemarle’s side[edit | edit source]

The explosion threw everyone into the water. Cushing stripped off his uniform and swam to shore where he hid until daylight. That afternoon, he stole a small skiff and paddled down-river to rejoin the Union forces at the river's mouth. Of the other men in Cushing's boat, one escaped, two drowned, and eleven were captured.

Albemarle sinks in eight feet of water, is later raised by the Union Navy[edit | edit source]

Cushing's attack blew a hole in Albemarle at the waterline "big enough to drive a wagon in." She sank in eight feet of water, which left her upper works still dry. Commander Alexander F. Worley, who had been appointed as her captain about a month earlier, salvaged her guns and shells and used them to defend Plymouth, North Carolina, against subsequent Union attack—futilely, as it transpired.

With the sinking of Albemarle, Plymouth, North Carolina, is exposed to capture[edit | edit source]

Albemarle and the launch quickly sank and, for the first time since spring, Union naval forces enjoyed undisputed control of the North Carolina sounds. When the fortunate Gushing made his way back and reported his success, Comdr. Macomb—the senior naval officer in the area—promptly took advantage of his new ascendency and attacked Plymouth, North Carolina.

Shamrock and Bazely lead the attack on Plymouth, North Carolina[edit | edit source]

Shamrock, lashed to tug USS Bazely, led a fleet through the winding channels of Middle River on 30 October and the next day engaged the town's batteries and rifle pits from close range. USS Commodore Hull suffered heavy damage in the violent battle which ensued. After the Union bombardment detonated a large magazine, the Confederate defenders evacuated the fortress. Soon a landing party raised the Stars and Stripes over Plymouth.

Continued operations in the North Carolina sounds[edit | edit source]

Through the ensuing winter, Comdr. Macomb, in Shamrock, directed operations in the sounds, assuring the Union control of these strategic waters as General Ulysses S. Grant relentlessly tightened his grip on Richmond, Virginia, and General William Tecumseh Sherman pushed his army northward from Georgia through the Carolinas. On 20 March 1865, Macomb reported the raising of Albemarle.

Shamrock remained in the sounds directing affairs afloat in the area for several months after the Confederate collapse. In mid-summer, she returned north and was decommissioned at the Philadelphia Navy Yard on 15 August.

Recommissioned after the war to serve in the Caribbean and visit Europe[edit | edit source]

Recommissioned on 17 October 1865, Shamrock next served in the Caribbean and was one of the nine ships comprising the West Indies Squadron which was reestablished on 2 December. The following year, the double ender crossed the Atlantic Ocean for service in European waters.

Second, and final, decommissioning and sale[edit | edit source]

She returned to the United States in July 1868 and was decommissioned at the Philadelphia Navy Yard on 10 August. Shamrock was sold on 1 September 1868 to Mr. E. Stannard of Westbrook, Connecticut.
