Chancellorsville and Gettysburg

These are his memoirs of service in two of the War's great campaigns. At Chancellorsville, a very promising start made by General Hooker against Lee's Confederate forces fell to a defeat when, in Doubleday's estimation, normal and prudent precautions against surprise in the heavily-wooded battlefield were not carried out; he also seemingly apologizes for Hooker's lack of leadership during the battle as a result of his having been stunned by a cannon ball hitting the post against which he was leaning.
