Whilst Lord Loudoun and James Murray found their imperial attitudes and ideas evolved as they adapted to the realities of the situation they faced on the ground in North America, Jeffrey Amherst staunchly adhered to his sense of British superiority in the wake of the French and Indian War. This chapter explores the factors that underpinned his attitude and the inflexible strategy it led him to pursue in the West. Investigating the militarisation of the interior, the chapter highlights the continuing influence of the Forty-Five on the British army in North America. Amherst drew parallels between the Indigenous peoples in the West whom he viewed as conquered peoples, subject to British authority, and defeated Jacobite rebels in Scotland. This led him to try and subjugate Indigenous peoples to secure peace, but his strategy failed as his policies instead encouraged several tribes and nations to unite against British authority, sparking a pan-Indigenous rising, Pontiac’s War, in 1763.
