The Forbes Expedition was a British military campaign undertaken in 1758 during the French and Indian War with the strategic objective of capturing Fort Duquesne, a French fort constructed in 1754 at the confluence of the Allegheny River and the Monongahela River. This expedition followed the unsuccessful Braddock Expedition earlier in the war, which had similarly aimed to seize this strategically important fortification located at what is now Pittsburgh's Golden Triangle.
Brigadier-General John Forbes led the expedition with approximately 6,000 men, including a contingent of Virginians commanded by George Washington. Despite being very ill, Forbes entrusted the advance of his army to his second in command, Lieutenant Colonel Henry Bouquet, a Swiss mercenary officer who commanded a battalion of the Royal American Regiment. As the expedition advanced toward Fort Duquesne, it methodically constructed the Forbes Road across the territory. A critical diplomatic development occurred when the Treaty of Easton resulted in a loss of Native American support for the French.
The French, anticipating the expedition's arrival and facing the loss of their Native American allies, destroyed Fort Duquesne before the British could capture it. The expedition reached the fort on November 24, 1758, finding it already destroyed. This outcome effectively secured the strategic objective of preventing French control of the fort, though not through direct military engagement.
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.
