Part of the eastern border was fixed after the Jay Treaty of 1797, but the upper Saint John River area remained disputed.

Both Maine and New Brunswick pressed development of the area to solidify their claims, but this consequently raised tensions beginning in the 1820s, with authorities from each government acting against the other's settlers and agents.

Scott and New Brunswick Lieutenant Governor John Harvey, who had a long-established friendship, were able to successfully reduce tensions until the Webster-Ashburton Treaty was negotiated in 1842.
