Fort Dewart: A Forgotten Fort of the French and Indian War
A couple of years ago, I had the opportunity to participate in a small film project at Fort Dewart, a remarkable surviving French and Indian War fortification in the Allegheny Mountains of Pennsylvania. During the project, I was also able to capture some aerial photographs and video footage of the historic site with my drone.
Located along the border of Bedford and Somerset counties, near the summit of Allegheny Mountain, Fort Dewart was constructed in August 1758 during the French and Indian War.
The fort was built by Scottish Highland soldiers of the 77th Regiment of Foot, known as Montgomerie's Highlanders, under Captain Sir Allan Maclean. Maclean named the fort after Duart Castle, the ancestral seat of Clan Maclean in Scotland.
Fort Dewart was established as part of British General John Forbes' military expedition against the French-held Fort Duquesne, located at present-day Pittsburgh. Forbes was advancing westward through Pennsylvania, constructing a military road and a series of fortified posts to protect his army's supply and communication lines.
Situated near the top of the difficult ascent through Rohr's Gap, Fort Dewart served as a defensive position, resting place, and supply stop for British troops and wagon convoys. Soldiers and animals could recover from the demanding climb while blacksmiths repaired damaged wagons, horseshoes, and equipment.
The fort itself was a relatively small, approximately 60-by-60-foot, star-shaped redoubt constructed of earth and timber.
What makes Fort Dewart particularly remarkable is its survival. Although the original wooden defenses have disappeared, the eighteenth-century earthen fortifications remain visible today. It is considered one of the best-preserved surviving military works associated with the 1758 Forbes Expedition.
General Forbes himself stayed at Fort Dewart for several days in October 1758, when heavy rains and muddy roads delayed his army's advance. The expedition eventually succeeded in taking possession of the abandoned French Fort Duquesne on November 25, 1758.
More than 268 years later, the surviving earthworks of Fort Dewart remain a remarkable reminder of the struggle for control of the Ohio Country during the French and Indian War.
Included are some of the aerial drone photos I captured during our filming project a couple of years ago.
