Civil War service

Gulf of Mexico operations 

Ordered to the Gulf of Mexico on 2 November, New London, aided by , captured the schooner Olive laden with lumber shortly before midnight on 21 November. Early the next morning, she took the steamboat Anna carrying turpentine and rosin from Pascagoula, Mississippi, to New Orleans, Louisiana.

About dawn a week later, she took the steamboat Henry Lewis carrying sugar and molasses; and that afternoon she captured a schooner trying to slip through the blockade with naval stores for Havana, Cuba. On 28 November 1861 she captured , which was later put into service in the U.S. Navy.

New London captured the steamer Advocate on 1 December; and the schooner Delight with sloops Empress and Osceola on 9 December. On the 28th the schooner Gypsy became her prize.

Operations on shore

Not content just to capture ships, New London, with  and Henry Lewis, rounded out her record on the last day of 1861 by sending a landing party ashore to capture Biloxi, Mississippi, destroying a Confederate battery and taking possession of two guns and the schooner Captain Spedden.

On 20 February 1862 a boat expedition from New London landed on Cat Island, Mississippi and interned 12 small sloops and schooners suspected of being pilot boats for blockade runners.

On 4 April, with  and , New London engaged CSS Carondelet, CSS Pamlico, and CSS Oregon while Henry Lewis landed 1,200 Union Army troops at Pass Christian, Mississippi and destroyed a Confederate camp there. Boats from New London captured the yachts Comet and Algerine near New Basin, Louisiana on 2 June. On 17 June she captured and destroyed batteries at North and South passes.

On 18 July, accompanied by the Grey Cloud, the New London approached the large hotel at Pascagoula and announced its arrival by firing two shells over the hotel.  Both steamers had been reinforced by men from the  for this raid. The New London docked at the Hotel Wharf at Pascagoula, Mississippi, and deployed about 60 sailors and marines to the village to capture mails and confiscate the telegraph equipment.  Sentries quickly spotted a Confederate cavalry patrol and the sailors and marines withdrew to their gunboats.  The Grey Cloud moved about a half-mile west and attempted to enter the Pascagoula River with the intent on capturing local schooners with turpentine and lumber.  However, the mouth of the river was obstructed to prevent passage.  At this point the gunboats stood off shore and put in three launches loaded with about 25 sailors and marines each and proceeded up the river.  About a mile from the mouth where the river is not but 200 yards wide, the launches were ambushed by a platoon of 30 troopers of the Mobile Dragoons under Lieut Hallett, a cavalry unit armed with Sharps carbines.  The launches returned fire, but where in the open and withdrew to the mouth of the river with eight or nine wounded.  Once the launches were clear, the New London fired 25 shells into the village and the Grey Cloud fired seven shells; however, only one civilian was reported slightly wounded.  After sitting off shore 19 July, the ships withdrew from the shoreline. Ref: Charleston Daily Courier, 29 July 1862

Blockading the Texas coast 

During the ensuing years New London served on blockade duty in the Gulf of Mexico, operating primarily off the Texas coast. She and  captured the British schooner Tampico off Sabine Pass, Texas, attempting to run out laden with cotton on 3 April 1863. On the 10th, while reconnoitering near Sabine City, a boat crew from New London captured a small sloop. Among the prisoners was Capt. Charles Fowler, CSN, who had commanded CSS Josiah Bell when the Confederate warship took  and  in January.

On 18 April, another boat expedition was surprised and driven off by Confederate troops.

On 7 July, with , New London engaged batteries below Donaldsonville, Louisiana. Three days later, while steaming to New Orleans, the ship engaged Confederate batteries at White Hall Point, Mississippi.

Back off the Texas coast, she captured the schooner Raton del Nilo on 3 December.

Post-war decommissioning and subsequent career 

New London continued to serve the West Gulf Blockading Squadron through the end of the Civil War. She sailed north on 12 July 1865 and decommissioned at Boston, Massachusetts, 3 August 1865. She was sold at public auction on 8 September 1865 to M. M. Comstock.

Redocumented as Acushnet on 27 December 1865, she operated in merchant service until 1910.
