Fort Trumbull is a Civil War Fortification
New London is a small city right in between Boston and New York. Just two hours from those two big cities, it often gets driven through by tourists heading to the major metropolitan areas or to beach shore destinations like Newport or Cape Cod. New London and the towns surrounding it have half a dozen Civil War destinations that include Fort Griswold and Fort Trumbull. In November, 2023 I visited Fort Trumbull right in the city.
The fort that is still in existence is largely the fort that was built between 1839 and 1852 that stood there during the Civil War. This was the third fort built there and it is in accord with the Third System of defensive fortifications. The site had been defended during the Revolutionary War with a fort built in 1777 that was captured in 1781 by Benedict Arnold. New London was burned by the British. After the war, a Second System fort was placed on the site. Both the first and second forts no longer exist except for a block house constructed in 1794 of granite.
