In November 1758 Brigadier General John Forbes’s army expelled the French army from Fort Duquesne at the forks of the Ohio River. Over seven months Forbes had co-ordinated three obstructive and competitive colonies, managed Indian diplomacy, and cut a road through over a hundred miles of mountain and forest.

This is the first full biography of Forbes, which traces his rise from surgeon in the Scots Greys to distinguished service in War of the Austrian Succession before his 1757 posting to North America. John Oliphant puts Forbes’ life and career in the wider context of the social and military world of the 18th century and offers important insights into the Seven Years’ War in North America.
