Controversy has raged round Burnside's plan of action and in particular round his orders to Franklin, as to which it can only be said that whatever chance of success there was in so formidable an undertaking as attacking the well-posted enemy was thrown away through misunderstandings, and that nothing but misunderstandings could be expected from the vague and bewildering orders issued by the general in command. The actual battle can be described in a few words. Jackson held the right of Lee's line, Longstreet the left, both entrenched. Franklin, tied by his instructions, attacked with one division only, which a little later he supported by two more (I. corps, Major-General J. F. Reynolds) out of eight or nine available. His left flank was harassed by the Confederate horse artillery under the young and brilliant Captain John Pelham, and after breaking the first line of Stonewall Jackson's corps the assailants were in the end driven back with heavy losses. On the other flank, where part of Longstreet's corps held the low ridge opposite Fredericksburg called Marye's Heights, Burnside ordered in the II. corps under Major-General D. N. Couch about 11 A.M., and thenceforward division after division, on a front of little more than 800 yds., was sent forward to assault with the bayonet. The "Stone Wall" along the foot of Marye's was lined with every rifle of Longstreet's corps that could find room to fire, and above them the Confederate guns fired heavily on the assailants, whose artillery, on the height beyond the river, was too far off to assist them. Not a man of the Federals reached the wall, though the bravest were killed a few paces from it, and Sumner's and most of Hooker's brigades were broken one after the other as often as they tried to assault. At night the wrecks of the right wing were withdrawn. Burnside proposed next day to lead the IX. corps, which he had formerly commanded, in one mass to the assault of the Stone Wall, but his subordinates dissuaded him, and on the night of the 15th the Army of the Potomac withdrew to its camps about Falmouth. The losses of the Federals were 12,650 men, those of the Confederates 4200, little more than a third of which fell on Longstreet's corps. See F. W. Palfrey, _Antietam and Fredericksburg_ (New York, 1881); G. W. Redway, _Fredericksburg_ (London, 1906); and G. F. R. Henderson, _Fredericksburg_ (London, 1889).
