The Forbes Expedition was a British military campaign during the French and Indian War aimed at capturing Fort Duquesne, a French fort constructed in 1754 at the confluence of the Allegheny River and the Monongahela River. The strategic objective was similar to that of the earlier unsuccessful Braddock Expedition—to seize this key French position, which was located at what is now Pittsburgh's Golden Triangle in the downtown area.
Brigadier-General John Forbes led the expedition in 1758 with approximately 6,000 men under his command, including a contingent of Virginians led by George Washington. Despite his severe illness, Forbes entrusted the advance of his army to his second in command, Lieutenant Colonel Henry Bouquet, a Swiss mercenary officer commanding a battalion of the Royal American Regiment. As the expedition advanced, it methodically constructed the Forbes Road across the region, establishing supply and communication lines.
The expedition's ultimate success was facilitated by the Treaty of Easton, which caused a significant loss of Native American support for the French. As a result of this diplomatic shift and the advance of Forbes's forces, the French destroyed Fort Duquesne before the expedition could arrive on November 24, 1758. This outcome represented a strategic British victory in the contest for control of the Ohio Valley region during the French and Indian War.
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.
