History & Significance

Fort Sandoské occupied a site formerly held about 1745 by a Pennsylvanian fur-trading post, before French soldiers from Fort Detroit expelled the English and took over the site around 1748–1749. The French briefly used the fort to secure supply and communication between Fort Niagara and Fort Detroit.

It stood near the Bay, somewhere southerly and easterly of the current City of Port Clinton, Ohio. The fort is known to have been abandoned by 1754.

The site's precise location remained uncertain for centuries due to shoreline erosion. French engineer Chaussegros de Léry drew the plan of the former Fort Sandoské in his campaign journal for 1754, providing the most detailed contemporary record of the fort's structure.

De Léry visited the area and sketched the remains of this fort's layout in 1754. The location has become submerged or eroded into Sandusky Bay over the past 270+ years, making archaeological investigation challenging. This specific site was never a British military outpost, although some historians asserted it had been—a confusion arising from the English trading post that preceded it.
