Book excerpt: Bruce Catton, Charles P. Roland, David Donald, and T. Harry Williams Edited, with a New Preface, by Grady McWhiney With a New Introduction by Joseph T. Glatthaar During the Civil War centennial, four eminent scholars of the conflict -- Bruce Catton, Charles P. Roland, David Donald, and T. Harry Williams -- gathered at a Northwestern University symposium to debate and commemorate this transforming event in American history. Originally published in 1964, Grant, Lee, Lincoln and the Radicals assembles their conference papers into one small volume that has become a giant in Civil War studies. Catton provides a brief but brilliant summary and assessment of Ulysses S. Grant's Civil War career and Roland does the same for Robert E. Lee's. The essays by Donald and Williams continue the historians' running debate on the relationship between Abraham Lincoln and the Radical Republicans. With an informative new introduction by Joseph T. Glatthaar and a new preface by Grady McWhiney, Grant, Lee, Lincoln and the Radicals continues to shape and illuminate the scholarship on these central Civil War figures.
