The Forbes Expedition was a British military campaign 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 objective was similar to that of the earlier unsuccessful Braddock Expedition. The expedition's importance lay in its role as part of Britain's broader efforts to seize control of French positions in North America during the colonial conflict.
Brigadier-General John Forbes led the expedition in 1758, commanding approximately 6,000 men, including a contingent of Virginians led by George Washington. Forbes, who was very ill, did not personally advance with the army but instead entrusted command of the advance to his second in command, Lieutenant Colonel Henry Bouquet, a Swiss mercenary officer commanding a battalion of the Royal American Regiment. While advancing toward Fort Duquesne, the expedition methodically constructed the Forbes Road across the region, which served as a crucial supply and communication line for the military operation.
The expedition's outcome was significantly influenced by the Treaty of Easton, which resulted in a loss of Native American support for the French. Recognizing the weakened position this created, the French destroyed Fort Duquesne before the British expedition could arrive on November 24, 1758. This destruction of the fort by the French forces prevented the direct capture of the installation by Forbes's army, though the expedition's ultimate strategic objective of removing French control from the location was achieved.
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.
