On 3 May 1804, three or possibly as many as six Aboriginal Tasmanians were killed and others wounded by approximately 75 colonists and soldiers of the New South Wales Corps stationed at the fledgling British settlement of Risdon Cove, Van Diemen's Land. Although some details of the massacre have been debated, eyewitness evidence indicated that at least three Aboriginal corpses were accounted for when "a great many were slaughtered and wounded" by the soldiers and colonists.
