We have seen how Prentiss, Sherman, McClernand were driven back; how, fight as fiercely as they would, they still lost ground; how their camps were all in the hands of the enemy; and how this whole front line, for which Hurlbut and Wallace were but the reserves, was gone. But the fortunes of the isolated brigade of Sherman's Division, on the extreme left, must not be forgotten. It was doubly let alone by the Generals. General Grant did not arrive on the field till after nearly all these disasters had crowded upon us, and each Division General had done that which was good in his own eyes, and carried on the battle independent of the rest; but this brigade was even left by its Division General, who was four miles away, doing his best to rally his panic-stricken regiments there. It was Commanded by Colonel David Stuart, (of late Chicago divorce-case fame, and ex-Congressman,) and was composed of the Fifty-fifth Illinois, Lieutenant-Colonel Malmbourg, commanding; Seventy-first Ohio, Colonel Rodney Mason; the Fifty-fourth Ohio, (Zouaves,) Colonel T. K. Smith. It was posted along the circuitous road from Pittsburgh Landing, up the river to Hamburgh, some two miles from the Landing, and near the crossing of Lick Creek, the bluffs on the opposite side of which commanded the position, and stretching on down to join Prentiss's Division on its right. In selecting the grounds for the encampment of our army, it seems to have been forgotten that from Corinth an excellent road led direct to Hamburgh, a few miles above this left wing of our forces. Within a few days, the oversight had indeed been discovered, and the determination had been expressed to land Buell's forces at Hamburgh, when they arrived, and thus make all safe. It was unfortunate, of course, that Beauregard and Johnston did not wait for us to perfect our pleasing arrangements. [Illustration: LIEUTENANT GENERAL SHERIDAN.] When the Rebels marched out from Corinth, a couple of brigades (rumored to be under the command of Breckinridge) had taken this road, and thus easily, and without molestation reached the bluffs of Lick Creek, commanding Stuart's position.
