Description: (1): Built in 1691, Fort Half-Moon was built to defend the town of Waterford, in Saratoga County, New York. The fort was built to protect the Schagticoke Native Americans on the west bank of the Hudson. The fort was located north of the city. It is possible that an existing fort from 1669 was relocated and rebuilt at this time. In 1691, the fort was garrisoned with 50 Fusiliers originally from Albany. By 1702 the fort was in ruin, but it was rebuilt in 1704. (2): In 1757, a fort was constructed in Waterford. The fort was built on three-foot stilts at the intersection of the Mohawk and Hudson Rivers, opposite Haver's Island. It was described in 1759 as a redoubt of poor quality. However, when Haver's Island was fortified in 1777, there was no mention of the fort, leading to doubts surrounding its existence. (3): 1757, Saratoga County, Waterford. A new fort was built on 3 foot stilts at the North point of land at junction of the Mohawk and Hudson Rivers, opposite Haver's Island. Described in 1759 as a poor redoubt. Fortification of Haver's Island in 1777 does not mention the fort.
