In his novel, Fair Blows the Wind, Louis L'Amour introduces a historical figure, General Hugo O'Connor, who befriends the hero of the book. He is supposed to be a commander in the Spanish army. There actually was such a man, although we do not find that he reached the rank of General until later on when he was in Mexico, where he served as Governor of northern Mexico, including Texas. Because of their unique political non-status, the Irish of that period often emigrated to other nations and served in military capacities. Hugo had two cousins serving in Spain, so he went there.
