Lord Castlereagh was prompt. As soon as was reasonably possible he sent more precise instructions. Dated August 14,[18] these supplementary instructions gave to those of July 28 a distinct outline. They proposed the Indian boundary fixed by the Treaty of Greenville for the permanent barrier between British and American dominion, beyond which neither government should acquire land. They claimed also a “rectification” of the Canadian frontier, and the cession of Fort Niagara and Sackett’s Harbor, besides a permanent prohibition on the United States from keeping either naval forces or land fortifications on the Lakes. Beyond these demands the British commissioners were not for the present to go, nor were they to ask for a direct cession of territory for Canada “with any view to an acquisition of territory as such, but for the purpose of securing her possessions and preventing future disputes;”[19] yet a small cession of land in Maine was necessary for a road from Halifax to Quebec, and an arrangement of the Northwestern boundary was required to coincide with the free navigation of the Mississippi. As soon as the new instructions reached Ghent the British commissioners summoned the Americans to another conference, August 19; and Goulburn, reading from Castlereagh’s despatch, gave to the Americans a clear version of its contents.[20] When he had finished, Gallatin asked what was to be done with the American citizens--perhaps one hundred thousand in number--already settled beyond the Greenville line, in Ohio, Indiana, Illinois, and Michigan? Goulburn and Dr. Adams replied that these people must shift for themselves. They added also that Moose Island and Eastport belonged to Great Britain as indisputably as the county of Northamptonshire, and were not a subject for discussion; but they would not then make a _sine qua non_ of the proposition regarding the Lakes. The conference ended, leaving the Americans convinced that their answer to these demands would close the negotiation. Clay alone, whose knowledge of the Western game of brag stood him in good stead, insisted that the British would recede.[21]
