The Northeast Coast campaign of 1703, also known as the Six Terrible Days, occurred during a period of contested territorial control between French Acadia and English New England. Following inconclusive battles during King William's War in the 1690s, territorial disputes remained unresolved, with New France claiming the Kennebec River in present-day southern Maine as Acadia's western border while English colonists disputed this claim. This fundamental disagreement over colonial boundaries created the conditions for renewed military conflict in the early 18th century.
The campaign was led by Alexandre Leneuf de La Vallière de Beaubassin, who commanded approximately 500 troops composed of French colonial forces and members of the Wabanaki Confederacy of Acadia, including 200 Mi'kmaq and others from Norridgewock. Operating between August 10 and October 6, 1703, these forces attacked English settlements along the coast of present-day Maine between Wells and Casco Bay, encompassing the area now known as Portland, Maine. The campaign resulted in the burning of more than 15 leagues of New England territory and the killing or capturing of more than 150 people. While English colonists successfully defended some settlements, numerous others were destroyed and subsequently abandoned.
The campaign's consequences were severe for the region. Historian Samuel Drake reported that "Maine had nearly received her death-blow" as a result of the military operations, underscoring the devastating impact on colonial settlement and survival in the area. The campaign represented the first major French offensive of Queen Anne's War in New England and demonstrated the vulnerability of English colonial settlements to coordinated Franco-Native American military action.
European colonization of North America accelerated after 1600, with England, France, Spain, and the Netherlands establishing competing settlements along the Atlantic coast, the St. Lawrence River, the Gulf of Mexico, and the Mississippi Valley. The first permanent English settlement at Jamestown, Virginia (1607) struggled with starvation and conflict; the Plymouth colony (1620) and the Massachusetts Bay Colony (1630) followed. By the mid-1700s, thirteen English colonies stretched along the Atlantic seaboard, governed through a mix of royal charters, proprietary grants, and elected assemblies. The colonial economy depended on tobacco in Virginia and Maryland, rice and indigo in the Carolinas, and maritime trade in New England — all increasingly reliant on enslaved African labor after 1619. Conflict with Indigenous peoples over land was continuous, punctuated by major wars including King Philip's War (1675–1676) in New England and the Yamasee War (1715–1717) in the South. The French and Indian War (1754–1763), part of the global Seven Years' War, ended French power in North America and left Britain deeply in debt — triggering the taxation disputes that would lead to revolution.
