ElMondoHummus,

The two views of Longstreet are not necessarily diametrically opposed. As a subordinate officer, you can offer your opinion, advice, best counsel until the commander makes his decision. Then you had best work darn hard to make the plan work. In time, should you survive to write memoirs, you can indeed point out how you remember the events and most writers cannot, even with the best of intentions, avoid overlooking their own blemishes and highlighting the blemishes of those poor benighted souls who did not heed their counsel. However, in history, as at Gettysburg, the center often holds.
