 They also burned the other abandoned Moravian villages in the area.This action, which came to be known as the Gnadenhutten massacre, caused an outright frontier war to break out between the Delawares and the Americans.After several years of ongoing campaigns by the natives to terrorize and keep out further American settlers, a brutal campaign by US General "Mad Anthony" Wayne from Fort Washington (now Cincinnati) was carried out in late 1793, eventually resulting in the Treaty of Greenville being signed in 1795 between the US government and the local natives.
