John C. O'Neill: The Irish Nationalist and U.S. Army Officer Who Invaded Canada

The three-day invasion was a military success but a political failure, yet O'Neill was celebrated for his leadership and humanity. Elevated to the presidency of the Fenian Brotherhood, "General" O'Neill would again lead Irish nationalists against Canada in 1870. Jailed and later pardoned by President U.S. Grant, O'Neill left the Fenians and attempted a third, futile attack into Canada.

O'Neill then became a colonizer, urging Irish Americans to abandon cities in the East to settle on the fertile plains of the West. O'Neill City, Nebraska, is named in his honor. This first full-length biography covers the rise, fall and resurgence of a remarkable figure in American and Irish history.
