I now remember exactly what I was refering to when I made this statement. I read John Gordon's "Reminiscences of the Civil War" last fall. In chapter 11 "Gettysburg" page 160 paragraph 2 and footnotes 1 and 2 Gordon does refer to Longstreet as one of the greatest American soldiers but acknowledged the controversies that surrounded him.
In footnote 1: "That General Lee distinctly ordered Longsrteet to attack early the morning of the second day, and if he had done so, two of the largest corps of Meade's army would not have been in the fight; but Longsreet delayed the attack until four o'clock in the afternoon, and thus his oppurtunity of occupying Little Round Top, the key to position, which he might have done in the morning without firing a shot or losing a man."
Footnote 2: "That General Lee ordered Longstreet to attack at daybreak on the morning of the third day, and that he did not attack until two or three o'clock in the afternoon, the artillery opening at one."
This was what I was refering too.
Thank you
Thie first was a widely believed story which was fabricated by Lee's Chief of artillery, Pemberton, after the war and disproven by Lee's staff officers.
The second story hardly had much currency.
I am suprised Gordon published such rumors without citing the source. Being subordinate to Longstreet and in a different Corps during the battle. It is unlikely that he would have any first hand knowledge of any orders or discussions from Lee to Longstreet
