The obsolete recorded thing in Southport’s history was “The Great Swamp Fight” or “Fairfield Swamp Fight” of July 1637 (not to be ashamed with the cutting edge Great Swamp Fight of King Philip’s War), an episode of the Pequot War in which English colonial forces led by John Mason and Roger Ludlow vanquished a band of 80 to 100 Pequot Indians who had earlier fled from their house territory in the Mystic Place and taken refuge with nearly 200 Sasqua Indians who inhabited the area that is now Fairfield. The truthful location of the fight is unclear, but it is known to have been in the vicinity of Southport. In 1639, Ludlow conventional the town of Fairfield on the Pequot land known as Unquowa. Colonial comings and goings of home were signed subsequently the Sasqua in the 1670s.

In the eighteenth century, Mill River village, a ration of Fairfield, was a small hamlet of a few houses and a dock at the mouth of Fairfield’s Mill River. Farm products from the surrounding Place were shipped from Mill River’s small port to ports in New York and beyond.
