The Cape Grim massacre occurred 10 February 1828 in the North west of Van Diemen`s Land, now known as Tasmania, when four shepherds with muskets are alleged to have ambushed over 30 Tasmanian Aborigines from the Pennemukeer band from Cape Grim, killing 30 and throwing their bodies over a 60 metre cliff into the sea. An unknown number were reported to have escaped. The hill where the massacre occurred was then called Victory Hill by the shepherds.
