Three new stations were thus established during the month of April, at widely separated points in the lower portion of the extensive county. The most remote of these isolated settlements was established under the leadership of John Dunlap, one of Symmes' numerous surveyors, upon the eastern bank of the Great Miami, eighteen miles northwest of Cincinnati, in a position almost encircled by a turn in the river. Some thirty persons went with Dunlap to this spot, and constructed a stockade fort similar in plan to Covalt's, but much more carelessly and inefficiently finished. The area of the fort was one acre square. Dunlap, who was an immigrant from Coleraine, Ireland, gave the name of his native town to the place; but the pioneers of the county, as was usual in the frontier districts of the West, knew the station by the name of its chief personage. The township in which the now empty site of the fort lies has inherited the Irish title. The names of some of Dunlap's settlers were Gibson, Larrison, Crum, Hahn and Birket.

The bloody defeat of Harmar encouraged the northern warriors to make a descent upon Hamilton county in full force. At daylight on Monday, January 10, 1791, the inmates of Dunlap's Station, the farthest outpost in the dreary wilderness, were startled from their slumbers by the dreaded Indian alarm, and sprang up to find the woods around their fort swarming with an army of red skins, commanded by the Shawnee chieftain, Blue Jacket, and the detested cutthroat renegade, Simon Girty. The garrison consisted only of a detachment of thirteen soldiers from Fort Washington, under Lieut. Kingsbury, and ten able-bodied settlers, while the savages numbered several hundreds; but as the chiefs would give no satisfactory promise of quarter, the besieged naturally refused to surrender. A continuous fire was poured in upon the stockade; and firebrands shot upon the roofs of the cabins, till midnight of the first day, when the besiegers retired a little distance from the fort, and burned to death a prisoner named Abner Hunt, whom they had captured a day or two before their appearance at, the station. The next morning a brave private soldier named Wiseman escaped from the station amid a shower of bullets, and carried the news of the attack to Fort Washington. He returned upon the third day with a party of Harmar's regulars and a company of mounted militia from Columbia; but the Indians had retreated about two hours before the reinforcement arrived, and were already beyond pursuit.
