Battle of Gettysburg
The Battle of Gettysburg () was fought July 1–3, 1863, in and around the town of Gettysburg, Pennsylvania, by Union and Confederate forces during the American Civil War. The battle involved the largest number of casualties of the entire war and is often described as the war's turning point. Union Maj. Gen. George Meade's Army of the Potomac defeated attacks by Confederate Gen. Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North.
Oliver Otis Howard
At the Battle of Gettysburg, the XI Corps, still chastened by its humiliation in May, arrived on the field in the afternoon of July 1, 1863. Poor positioning of the defensive line by one of Howard's subordinate division commanders, Brig. Gen. Francis C. Barlow, was exploited by the Confederate corps of Lt. Gen. Richard S. Ewell and once again the XI Corps collapsed, forcing it to retreat through the streets of Gettysburg, leaving many men behind to be taken prisoner. On Cemetery Hill, south of town, Howard quarreled with Maj. Gen. Winfield S. Hancock about who was in command of the defense. Hancock had been sent by Maj. Gen. George G. Meade with written orders to take command, but Howard insisted that he was the ranking general present. Eventually he relented. Controversy centers on three points: 1) Howard's choice of Cemetery Hill as the key to defense; 2) the timing of Howard's mid-afternoon order to abandon positions north and west of town; and 3) Howard's reluctance to recognize that Hancock, his junior, had superseded him. Historian John A. Carpenter holds that Howard alone had wisely selected Cemetery Hill, that the order to withdraw was probably a sound one, and that the conflict between Howard and Hancock might have been avoided had Meade himself gotten onto the field.
