On June 1, 1866, one thousand heavily-armed Irish-American Fenian insurgents invaded Upper Canada across the Niagara River from Buffalo, NY. The next day near the town of Ridgeway, 800 Fenians battled with 850 Canadian volunteer soldiers, including a small company of 28 University of Toronto students who ended up taking the brunt of the attack. The Battle of Ridgeway (or Lime Ridge or Limestone Ridge) ended with a disastrous rout of the Canadians who in their panicked retreat left their dead and wounded on the field. It was the last major incursion into Canada, the last battle in Ontario and the first modern one fought by Canadians, led in the field exclusively by Canadian officers, and significantly fought in Canada. The Fenian Raid mobilized some 22,000 volunteer troops and resulted in the suspension of habeas corpus in the colonial Province of Canada by its Attorney General and Minister of Militia John A. Macdonald, but the battle which climaxed this crisis is only prominent by its obscurity in Canadian historiography. Almost everything known and cited about Ridgeway springs from the same sources—four books and pamphlets—three of them published in the summer of 1866 immediately after the event and the remaining one in 1910. This dissertation argues that the history of the battle was distorted and falsified by these sources and by two military board of inquiries staged to explicitly cover up the extent of the disaster. This study investigates the relationship between the inquiries and the contemporary author-historians of two of the sources: Alexander Somerville, an investigative journalist in Hamilton, Ontario, a recent immigrant from Britain with a controversial history; and George T. Denison III, a prominent young Toronto attorney, a commander of a troop of volunteer cavalry, a former Confederate secret service agent, author-commentator on Canada’s military policy and presiding judge on both boards of inquiry. This study describes the process by which Ridgeway’s history was hidden and falsified and its possible scope and significance in Canadian historiography. New archival and published sources are identified, assessed and assembled for a newly restored and authenticated micro-narrative of the battle.
