This book is a copy of the author's finding aid for Audit Office 12. The original documents that constitute Audit Office 12 are stored in the National Archives in London, England. Audit Office 12 contains documents of nine commissions. Essentially all of Audit Office 12 concerns monetary claims by American Loyalists for relief, compensation, or other payments, as a consequence of the American Revolution. The body of material, thus collected, contains considerable information about the politics of the revolution, the conduct of the war, and the experiences of individual Loyalists. All of Audit Office 12 was microfilmed by the Public Archives of Canada (now part of the Library and Archives of Canada) on microfilm reels B-1155 to B-1183. This book is based on that microfilm copy.
