Castine

Bagaduce Harbor

Landmark · Castine Harbor, Castine, ME 04421

The harbor below Fort George where the American fleet of more than forty vessels anchored during the 1779 siege. The harbor's geography — deep, well-sheltered, commanded by the high ground above — made it a strategic position worth fighting over. The same waters where the American fleet lay at anchor in July 1779 are today a quiet Maine harbor.

Dyce's Head Lighthouse

Landmark · Dyce's Head, Castine, ME 04421

The lighthouse at Dyce's Head marks the entrance to Castine Harbor and the Bagaduce River. The high ground here was among the terrain contested during the 1779 siege; American forces gained a position near the harbor entrance in the early days of the expedition before command paralysis prevented follow-through.

Fort George

Battlefield · Battle Ave, Castine, ME 04421

The British fortification constructed in the summer of 1779 on the high ground above Bagaduce Harbor, which the American Penobscot Expedition failed to capture. Earthwork remains are preserved on the site and are accessible to visitors. Fort George was the objective of the entire expedition; its survival after three weeks of American siege operations was the central fact of the disaster.
