Carroll is sentenced and hung in Wexford. He had "fought the Saxon foemen by Slaney's glancing wave" and now "the silent churchyard blossom blooms softly over him."
I do not know if "Carroll Ban" refers to an historic person. - BS
I believe it does, given the nature of John Keegan Casey's work (he also wrote "The Rising of the Moon"). But I can't find a 1798 hero named "Carroll." Perhaps it's a code name? - RBW
