The Failure of Abercromby's Attack on Fort Carillon, July 1758, and the Scapegoating of Matthew Clerk

The unsuccessful attack by a massive British army against the French position at Fort Carillon (Fort Ticonderoga) on July 8, 1758 came as a shock to the British Empire. The failure of the attack has been attributed to a range of causes. The most prominent among them has been the accusation that an over-optimistic report on the French defenses made by a young engineer, Matthew Clerk, was the reason for an unsuccessful frontal attack. While many historians place the blame for the defeat on general mismanagement of the British army by the expedition’s commander, General James Abercromby, few have disputed the general’s claim that Clerk deserves a large share of the blame. Evidence from letters and other documents associated with the engineer serves to clarify a complex and confusing episode in the history of the French and Indian War.
