At the beginning of the conflict, despite the disproportion of the forces involved, the French and their allies managed to inflict defeats to the British, such as the Battle of Fort Necessity or the Battle of the Monongahela. Following the capture of Fort William Henry, the Marquis de Montcalm agreed to let the British withdraw with full honours of war - a civility that was not understood by some natives who massacred the British and their camp followers on their way to Fort Edward.
