Fort Trumbull
Fort Trumbull is a fort near the mouth of the Thames River on Long Island Sound in New London, Connecticut and named for Governor Jonathan Trumbull. The original fort was built in 1777, but the present fortification was built between 1839 and 1852. The site lies adjacent to the Coast Guard Station New London and is managed as the 16-acre Fort Trumbull State Park by the Connecticut Department of Energy and Environmental Protection. History. In 1775, Governor Jonathan Trumbull recommended building a fortification at the port of New London to protect the seat of the government of  Connecticut. The fort was built on a rocky point of land near the mouth of the Thames River on Long Island Sound; it was completed in 1777 and named for Governor Trumbull, who served from 1769 to 1784. It was attacked in 1781 during the American Revolutionary War, and was captured by British forces under the command of Benedict Arnold. Arnold's raid. Benedict Arnold had changed his allegiances by this time, and he was serving as a brigadier general in the British Army when he led a raid on Groton and New London, Connecticut on September 6, 1781. Two  bodies of troops were landed on either side of the mouth of the Thames River and marched towards Fort Trumbull in New London and Fort Griswold in Groton. Fort Trumbull fell after little resistance, but about 150 Connecticut militiamen made a gallant stand at Fort Griswold in the Battle of Groton Heights. The British were finally able to enter the fort, and militia commander Lieutenant Colonel William Ledyard offered his sword to Major Bromfield, the British commander on the scene, as a token of surrender. According to contemporaneous accounts, Bromfield took the sword from Ledyard and drove it through him , and the British then proceeded to massacre the surviving defenders. Eighty-five of the militiamen were killed and the others were either severely wounded, taken prisoner, or managed to escape. After the capture of both forts, the British proceeded to burn New London and then returned to their ships. An account of the battle published in a Philadelphia newspaper follows: - Extract of a letter from New London, dated Sept. 12. "Never was there more distress in any place than there is here at present; there are 50 widows within 8 miles of Groton fort". 19th century. The fort was repaired  circa 1808, and redesigned and rebuilt in 1812 to meet changing military needs under the second system of US fortifications. First a redoubt was built at the site to react to threat of British attack. Secretary of War Henry Dearborn's report on fortifications for December 1811 describes the fort as "an irregular enclosed work of masonry and sod, mounting 18 heavy guns [with] a brick barracks for one company". The present fortification replaced the older fort, and was built between 1839 and 1852 as a five-sided, four-bastion coastal defense fort. It could accommodate 42 guns on the  seacoast fronts, plus 10 additional guns in two flanking batteries outside the fort, along with flank howitzers in bastions for close-in defense. The new fort was built under the supervision of Army engineer George Washington Cullum, who later served as superintendent of the United States Military Academy at West Point, New York. During the Civil War, Fort Trumbull served as an organizational center for Union troops and headquarters for the 14th US Infantry Regiment. Here, troops were recruited and trained before being sent to war. Fort Trumbull was briefly commanded by John F. Reynolds, who rose to the rank  of major general and was killed at the Battle of Gettysburg in 1863. From 1863 to 1879, Ordnance Sergeant Mark Wentworth Smith was assigned to Fort Trumbull and served as the caretaker of Fort Griswold, which was an un-garrisoned subpost of Fort Trumbull across the Thames River in the town of Groton. Among other duties, he maintained a vegetable garden to help feed the soldiers at Fort Trumbull. Smith was born in New Hampshire in 1803 and enlisted in the Army on January 27, 1827 at the age of 23. He was wounded in action at the Battle of  Chapultepec during the Mexican War. For unknown reasons, he was allowed to serve on active duty in the Army until his death in 1879 at the age of 76. He was possibly the oldest enlisted man to serve on active duty in the United States Army in the 19th Century. (Army Air Forces Master Sergeant John W. Westervelt served on active duty during World War II until he was retired at age 77 in 1945. Chief Torpedoman's Mate Harry S. Morris was born in 1888 and served in the Navy from 1903 to 1958 when he was "only" 70  years old.) Sergeant Smith is buried in the Colonel Ledyard Cemetery in Groton. In the late 1800s Fort Trumbull was modified to accommodate more modern artillery pieces. Specifically, these artillery pieces were 15-inch and 10-inch Rodman smooth bore guns and 8-inch converted rifles. Two 8-inch converted rifles are still at Fort Trumbull in a restored firing position. 20th century. Coast Guard Academy. After the Civil War, Fort Trumbull was improved by having more modern artillery pieces installed. In the early 1900s, several more modern Endicott era fortifications were built to defend Long Island Sound as the  Harbor Defenses of Long Island Sound, including Fort Mansfield in Watch Hill, Rhode Island, Fort H.G. Wright on Fishers Island, and Fort Michie on Great Gull Island. Fort Trumbull served as the headquarters of these forts until it was turned over to the Revenue Cutter Service (later renamed the Coast Guard) in 1910 for use as the Revenue Cutter Academy, which was renamed the United States Coast Guard Academy in 1915. The Academy moved to its current location about two miles up the Thames River in 1932. Education facility. Fort Trumbull served as the Merchant Marine Officers Training School from  1939 to 1946 and trained over 15,000 of the Merchant Marine officers who served during the Second World War. One of the Merchant Marine officers trained there was actor Jack Lord, who is best known for playing Steve McGarrett on the popular TV series "Hawaii Five-O" in the 1960s and 70s. The Fort was the site of a satellite campus of the University of Connecticut from 1946 to 1950, educating war veterans attending college under the GI Bill. Naval Underwater Sound Laboratory. During World War II, Fort Trumbull hosted an office of Columbia University's Division of War Research , which developed passive sonar systems. By 1946, this was consolidated with Harvard University's Underwater Sound Laboratory at Fort Trumbull. A result of this work was that Fort Trumbull was the location for the Naval Underwater Sound Laboratory from 1946 to 1970, which developed sonar and related systems for US Navy submarines. In 1970, the Sound Laboratory was merged with the Naval Underwater Weapons Systems Center (NUWS) to form the Naval Underwater Systems Center (NUSC) in Newport, Rhode Island. Work continued at both locations until the facility at Fort Trumbull was finally closed in 1996, marking the end of almost  a century and a half of Fort Trumbull's service as a federal military facility. State park. After a redevelopment period lasting several years, Fort Trumbull was opened as a state park in the year 2000. It is used as a site for concerts and other special events. The main fort is open to the public and has an elevator to access the upper portions of the fort. There is a museum about the fort in the former officers' quarters.
