Getting Your Head Around New London's Past
New London sits at the mouth of the Thames River on Connecticut's southeastern coast. It was originally Pequot territory before English settlers moved in during the mid-1600s. The area was first called Nameaug, then New London was incorporated in 1658. The story that follows isn't some dramatic origin myth. It's just a record of what happened here over the next three and a half centuries. The early history is tied to the Pequot War. The town grew slowly as a fishing and trading post. By the 1700s, it was involved in the triangular trade along with other Connecticut River towns. That includes the part most people don't want to talk about, which is the involvement in the slave trade. New London merchants were active participants. This isn't an edge case or a footnote. It's well documented in port records and merchant correspondence held at the New London County Courthouse archives. The 1800s brought the whaling industry. New London became one of the busiest whaling ports on the East Coast. The city's waterfront filled with shipyards and processing facilities. When the whaling industry declined after the Civil War, the city pivoted to boatbuilding and marine manufacturing. That shift defined the local economy for nearly a century. Companies like Groton Iron Works and the Electric Launch Company (Elco) put New London on the map for naval vessel construction. Elco built the PT boats used extensively in the Pacific Theater during World War Two.
The submarine development angle is where things get interesting for anyone digging into the technical side. General Dynamics moved Submarine Division operations here in the late 1940s, and the Navy established a major presence. The Submarine Base at Groton, right across the river, became one of the most important naval installations in the country. This isn't just filler context. It directly shaped the demographic and economic landscape of the entire region for the next sixty years.
What Actually Happened During the Great Flood of 1955
September 1955. Hurricane Diane hit the region and dumped an enormous amount of rain in a very short window. The Thames River breached its banks in several places. A large section of downtown New London was underwater. Multiple blocks of the commercial district were destroyed. The flood damage was estimated at over fifty million dollars at the time, which is roughly half a billion today adjusted for inflation. Most history books gloss over the details. The real story is in the Federal Emergency Administration of Public Works records and the U.S. Army Corps of Engineers reports. Those documents show exactly where the water levels exceeded historical maxima and how the urban layout amplified the damage. The downtown area sat in a natural floodplain that had been built over without adequate consideration for the river's behavior during extreme events. After the flood, the city underwent a major redevelopment. Many old structures were removed and replaced with wider streets and parking lots. Some historians argue this decision erased significant architectural heritage from the 1800s and earlier. The current downtown streetscape is largely a product of that post-flood reconstruction era. If you walk around downtown now, the older buildings you see are mostly the ones that survived or were reconstructed on original foundations.

Where to Actually Find the Records
The New London Free Public Library has a local history collection. It's not fancy. The microfilm readers are old and the card catalog system is partially digitized but not completely. The staff there know where everything is. They also know which boxes haven't been dusted since the nineties. Bring patience. Spend at least two hours if you're looking for something specific. The New London Maritime Society maintains documents and artifacts related to the city's seafaring past. Their collection includes ship logs, captain's papers, and photographs. It's a small operation running on volunteer energy. Access is by appointment. Call ahead and ask specifically for what you need. Random browsing here is inefficient because the materials are organized by donor and accession number rather than by date or subject in any straightforward way. The Norwich Historical Society holds records that overlap with New London's early colonial period. Many documents from the Pequot and Nameaug periods are split between multiple institutions because the original townships and land grants crossed what are now county lines. Don't assume everything about New London's early history is filed in New London.
For the whaling era, the Pequot Library's special collections has the strongest holdings. The catalog is searchable online. Use it before you go. I learned this the hard way once. I spent an afternoon at the library only to discover a box of 1850s shipping manifests I needed had been relocated to off-site storage without being updated in the public catalog. The workaround was simple but not obvious: I asked the head archivist directly instead of relying on the online system. She pulled it within twenty minutes. Online catalogs for regional historical societies are useful as a starting point but they are not reliable for locating physical items. Always verify with a person.
Things Most People Miss About This History
The connection between New London and Groton is something beginners tend to treat as separate. It isn't. Groton was originally part of New London and split off in 1705. The submarine base, the shipyards, the river traffic, the economy. These are shared histories. If you're researching one, you will run into the other constantly. Treat them as a single urban and industrial system and your research gets a lot clearer. Another thing that gets overlooked is the Native American continuity. The Pequot, Mohegan, and Narragansett peoples never disappeared from this area. Their presence and land claims predate European settlement by thousands of years and continue to the present. Many histories treat Indigenous history as a closed chapter rather than an ongoing reality. The Mohegan Tribe's headquarters is actually in nearby Uncasville, which was formerly part of New London. Their cultural and political influence on the region is substantial and it extends far beyond what you'll find in standard tourism materials. The naval presence created a unique demographic pattern. Military personnel and defense contractors move in and out regularly. This means census data, school records, and property records from the mid-twentieth century can be tricky to interpret. People who appear in one decade's records may have been stationed there temporarily and moved elsewhere. Family histories built on those records often have gaps that aren't gaps at all, just signs of military rotation that the record system doesn't capture well.
Limitations You Should Know About
The biggest problem with researching New London's history is that several major fires and the flood destroyed primary source material. The 1866 fire that burned through part of downtown took many early municipal records with it. You will hit walls where records simply do not exist. There is no workaround for that. It just means you have to rely on secondary sources, newspaper accounts, and whatever was saved in private collections. The New London whaling industry produced an outsized amount of personal papers and logs because many captains came from prominent local families who preserved those documents. But the ordinary sailors and workers, including many Black residents who worked in the shipyards and on the waterfront, left far fewer traces. Any history written solely from surviving documentary sources will be skewed toward the experiences of wealthier, white, male residents. You have to read against the grain of the archive and look for clues in court records, tax lists, and church registers to recover other perspectives. Digitization efforts in this area are incomplete and uneven. Some collections are fully digitized and searchable. Others exist only on microfilm or in physical boxes. A few are in neither format and only accessible by visiting in person. Plan accordingly. If you are doing this research remotely, your options are significantly more limited than if you can spend time in the city.
