It should not be confused with Fort Dayton, which was located on the north side of the Mohawk River, in what is now Herkimer, New York.
A joint British and Onondaga force attacked German Flatts and the forts on each side of the river in 1778.
They captured some of the settlers who were outside the southern fort, including three children of the Demuth family: Catherine, George, and Samuel.
After the two older children returned to their family during a prisoner exchange but Samuel, the youngest Demuth captive, had been adopted by the Onondaga and chose to stay with them, as he had become assimilated.
He later settled with them on a reservation near Syracuse, from where he kept in touch with his family and acted as an interpreter for the Onondaga and settlers.
