By winter 1829 the southern part of the Settled Districts had become a war zone and Aboriginal people later identified campsites where their relatives had been killed and mutilated. Several more incidents were reported in which Aboriginal people were raiding huts for food and blankets or digging up potatoes, but they too were killed. In an effort to conciliate Aboriginal people, Arthur arranged for the distribution of "proclamation boards" comprising four panels that depicted white and black Tasmanians dwelling together peaceably, and also illustrated the legal consequences for members of either race that committed acts of violence—that an Aboriginal would be hanged for killing a white settler and a settler would be hanged for killing an Aboriginal person.[42] No colonist was ever charged in Van Diemen's Land, or committed for trial, for assaulting or killing an Aboriginal person.[43]
