12th. That the original advance of General Wallace's Division on the Purdy Road, while thoroughly suited to the original conditions as they existed when the order was delivered to him, was, of necessity, useless and dangerous, when he found himself alone and unsupported, and that the enemy had already swept over the position which he expected to occupy.
13th. That there was no alternative, then, but to pass around the left of the enemy, and rejoin the army, at such expense of time or labor as the new conditions imposed; and that this was done, at great pains and with great celerity, without straggling or loss.
14th. That the prominent idea of withdrawing General Wallace's Division from Crump's Landing, to support the main army in its advance, is to be kept in mind;--whereby, confusion ceases as to the hour of the day when the order to report at Pittsburg Landing was delivered or became operative;--thereby, also, reconciling memories with the incidents of the day, with no discredit to any.
15th. That every theory of supporting an advanced line, from reserves sent forward from the base, must so bend to facts, that it may be the best thing possible, to strengthen the right of a successful line, even to overlapping and turning the enemy; and that such a movement has the emphatic endorsement of standard critics, and marked experience; while a formal movement to the rear, in order to move to the front and the right, as if on parade, would, under conditions such as presented to General Wallace, have been, simply, to wear out his men in marching, with small chance for taking any part in the assumed pursuit of a defeated enemy.
16th. That it is an unsound way of dealing with the facts of history, to gauge the responsibilities of officers and men, of small experience, by the rules which apply to the same officers and men after their experience has matured; and that, when the battle of Shiloh took place, and citizen regiments took part, with very slight knowledge of arms, it was equally true, that the officers themselves, both regular and volunteer, were proportionately unfamiliar with battle action on a large scale, and that, as a matter of fact, the Generals and Colonels, for the most part, had never seen a batallion drill, unless at West Point, much less drilled more than a company; and their conduct and opinions, in 1861-2, are not to be measured by the ripened experience of the years succeeding and succeeding years of reflection.
