A fairly stirring historical novel deals with one of the lesser, and less known, facets of the Mexican War which coincided in time with the Irish Potato Famine so that Irish immigrants were recruited to join the Army with the promise of early citizenship. Once in Mexico, they discovered that they were to fight on the side of an invader against a Catholic people with whom they had much in common. Quick to capitalize on this, General Santa Anna established a Saint Patrick's Battalion in the Mexican army and encouraged the Irish to desert the U.S. Army and join the Mexicans. The hero here, Michael Fitzgerald, is a man at first unwilling to turn against the American cause for which he volunteered. But he is found when wounded by a Mexican guerilla leader, Don Esteban, and nursed back to health by the Don's beautiful daughter, Raquel, with whom he falls in love. He finally joins the Battalion in the last days of the war, in time to be tried for treason with the rest of the survivors. It is an exciting story with strong romantic values and it should please readers of this genre.
