Massacred by Republicans and enslaved Natives...............
Maybe the latter, but it would be hard to spin the former (monarchist Tories) as “Republicans”...
The war up there was brutal; I read an account of a column of Tories being intercepted trying to reach Canada, and they were found with “bales of scalps” (apparently they offered incentives to Indians to kill those colonists seeking independence, and these were proof before payment).
