No book has been written about the case of William Walker, but Otto Friedrich recommends several general studies of blacks in the Union Army: Thomas Went-worth Higginson’s Army Life in a Black Regiment , originally published in 1869 and reprinted in a Norton paperback in 1984; Rehearsal for Reconstruction: The Port Royal Experiment , by Willie Lee Rose, Oxford paperback, 1976; One Gallant Rush: Robert Could Shaw and His Brave Black Regiment , by Peter Burchard, published in 1965 by St. Martin’s Press. On the subject of New York’s draft riots, he suggests James McCague’s The Second Rebellion, The Story of the New York City Draft Riots of 1863 . This was published by Dial Press in 1968.
