The Forbes Expedition was a British military expedition led by Brigadier-General John Forbes in 1758, during the latter stages ofthe French and Indian War. Like the earlier unsuccessful Braddock Expedition early in the war, the strategic objective was the capture of Fort Duquesne, a French fort constructed at the confluence of the Allegheny and Monongahela Rivers in 1754 (site of present-day downtown Pittsburgh, Pennsylvania's Golden Triangle).
