I am looking for material (letters, journals, military papers, etc.) to or
from British military personnel (or any other English speakers) who may
have been on or passed through the Niagara Frontier during the 5-year
period beginning with the capture of Fort Niagara in 1759 to the
construction of Fort Erie in 1764. Particularly looking for material that
is not published or online, primarily for the 1759-1764 period but also
interested in anything up through 1796. Can anyone suggest any likely
sources?
