Fort George was a British colonial fort, erected in 1715 - 1737, that was located in Pejepscot (Brunswick), when Maine was under jurisdiction of the Province of Massachusetts Bay.
During King Philip's War in 1676, Pejepscot was burned and abandoned, although a garrison called Fort Andross was built on the ruins during King William's War. During the war, in Major Benjamin Church's second expedition a year later, he arrived on 11 September 1690 with 300 men at Casco Bay. He went up the Androscoggin River to the English Fort Pejepscot (present day Brunswick, Maine). From there he went 40 miles up-river and attacked a native village. Three or four native men were shot in retreat; when Church discovered 5 English captives in the wigwams, six or seven prisoners were butchered as an example; and nine prisoners were taken. A few days later, in retaliation, the natives attacked Church at Cape Elizabeth on Purpooduc Point, killing 7 of his men and wounding 24 others.
After Queen Anne's War, Fort George was built in 1715 by Captain John Gyles in Brunswick. The fort was 3 feet (0.91 m) underground with a 3-foot-thick (0.91 m) wall base, standing at least 10 feet (3.0 m) high above ground, laid with lime mortar. The barracks housed fifteen men. A large two-story dwelling house, appearing above the walls, made living possible. The range of its cannon protected the dwellings within their reach.
During Father Rale's War, the inhabitants of Brunswick were hospitably gathered within the refuge. Many times this hospitality was strained to its most generous capacity as the onslaughts of Indian attacks were incessant. The most significant attack was when the fort was under siege during the early days of Father Rale's War (1722).
