Book excerpt: The valorous but troubled career of the Civil War general best known for defending Little Round Top and averting a Union defeat at Gettysburg. The lieutenant colonel of a New York regiment and rising star in the Army of the Potomac, Gouverneur K. Warren performed heroically at Gettysburg. For his service at Bristoe Station and Mine Run, he was awarded command of the Fifth Corps for the 1864 Virginia campaign. But Warren’s peculiarities of temperament and personality put a cloud over his service at the Wilderness and Spotsylvania and cost him the confidence of his superiors, Grant and Meade. He was summarily relieved of his command by Philip Sheridan after winning the Battle of Five Forks, just eight days before Appomattox. Warren continued as an engineer of distinction in the Army after the war, but he was determined to clear his name before a board of inquiry, which conducted an exhaustive investigation into the battle, Warren’s conduct, and Sheridan’s arbitrary action. However, the findings of the court vindicating Warren were not made public until shortly after his death. For this major biography of Gouverneur Warren, David M. Jordan utilizes Warren’s own voluminous collection of letters, papers, orders, and other items saved by his family, as well as the letters and writings of such contemporaries as his aide and brother-in-law Washington Roebling, Andrew Humphreys, Winfield Hancock, George Gordon Meade, and Ulysses S. Grant. Jordan presents a vivid account of the life and times of a complex military figure.
