 The American Revolutionary War brought the demise of these first settlements.The Delawares, who at the time populated much of eastern Ohio, were divided over their loyalties, with many in the west allied with the British out of Fort Detroit and many in the east allied with the Americans out of Fort Pitt.Delawares were involved in skirmishes against both sides, but by 1781 the American sense was that the Delawares were allying with the British.
