In the "Nation" of 10 January 1846, Mitchel reviewed Carlyle's annotated edition of Oliver Cromwell's correspondence and speeches only two weeks after it had been publicly condemned by O'Connell. Despite Mitchel himself waxing indignant at Cromwell's conduct in Ireland, Carlyle was pleased: he believed Mitchel had conceded Cromwell's essential greatness. Mitchel had just published his own hagiography of the Ulster rebel chieftain Hugh O'Neill, which both Duffy and Davis had found excessively "Carlylean". The book was a success: "an early incursion of Carlylean thought into the romantic construction of the Irish nation that was to dominate militant Irish politics for a century." It embraced Carlyle's view both of "Heroes, Hero-Worship, and The Heroic in History" (1840) and of the importance of racial identities trampled and compromised in the name of "what is called civilisation".
