From the US Declaration of Independence

He has excited domestic insurrection among us, and has endeavored to bring on the inhabitants of our frontiers the merciless Indian savages, whose known rule of warfare is an undistinguished destruction of all ages, sexes, and conditions.

From the Loyalist's Rebuttal

HUTCHINSON. These, my Lord, would be weighty charges from a loyal and dutiful people against an unprovoked Sovereign. They are more than the people of England pretended to bring against King James the Second in order to justify the Revolution. Never was there an instance of more consummate effrontery. The Acts of a justly incensed Sovereign for suppressing a most unnatural, unprovoked Rebellion are here assigned as the causes of this Rebellion. It is immaterial whether they are true or false. They are all short of the penalty of the laws which had been violated. Before the date of any one of them, the Colonists had as effectually renounced their allegiance by their deeds as they have since done by their words. They had displaced the civil and military officers appointed by the King’s authority and set up others in their stead. They had new modeled their civil governments and appointed a general government, independent of the King, over the whole. They had taken up arms, and made a public declaration of their resolution.
