The Battle of Gettysburg is haunted by "what ifs." Why did General Sickles move his Third Corps forward without orders? Sickles claimed this was the proper tactical maneuver. The position favored by Meade was "in a hole." At Chancellorsville, a few months earlier, he had been ordered to give up a dominating height, to retreat to low ground. The Confederates then occupied the height, and bombarded Sickles' Corps. Thus, at Gettysburg, he was not content sitting in a hole.
