In 1755, New England troops embarked on a "great and noble scheme" to expel 18,000 French-speaking Acadians ("the neutral French") from Nova Scotia, killing thousands, separating innumerable families, and driving many into forests where they waged a desperate guerrilla resistance. The right of neutrality; to live in peace from the imperial wars waged between France and England; had been one of the founding values of Acadia; its settlers traded and intermarried freely with native Mìkmaq Indians and English Protestants alike. But the Acadians' refusal to swear unconditional allegiance to the British Crown in the mid-eighteenth century gave New Englanders, who had long coveted Nova Scotia's fertile farmland, pretense enough to launch a campaign of ethnic cleansing on a massive scale.
