Yet with all this brave show, we have seen that Burnside's subordinate officers were unanimous in their belief in the rashness of the undertaking. Enthusiasm was sadly lacking. The English military writer, Colonel Henderson, has explained why this was so: And yet that vast array, so formidable of aspect, lacked that moral force without which physical power, even in its most terrible form, is but an idle show. Not only were the strength of the Confederate position, the want of energy of preliminary movements, the insecurity of their own situation, but too apparent to the intelligence of the regimental officers and men, but they mistrusted their commander. Northern writers have recorded that the Army of the Potomac never went down to battle with less alacrity than on this day at Fredericksburg. The first advance began at 8:30 in the morning, while the fog was still dense, upon Jackson's right. Reynolds ordered Meade with a division, supported by two other divisions under Doubleday and Gibbon, to attack Jackson at his weakest point, the extreme right of the Confederate lines, and endeavor to seize one of the opposing heights. The advance was made in three lines of battle, which were guarded in front and on each flank by artillery which swept the field in front as the army advanced. The Confederates were placed to have an enfilading sweep from both flanks along the entire front line of march. When Reynolds' divisions had approached within range, Jackson's small arms on the left poured in a deadly fire, mowing down the brave men in the Union lines in swaths, leaving broad gaps where men had stood. This fire was repeated again and again, as the Federals pressed on, only to be repulsed. Once only was the Confederate line broken, when Meade carried the crest, capturing flags and prisoners. The ground lost by the Confederates was soon recovered, and the Federals were forced to retire. Some of the charges made by the Federals during this engagement were heroic in the extreme, only equaled by the opposition met from the foe. In one advance, knapsacks were unslung and bayonets fixed; a brigade marched across a plowed field, and passed through broken lines of other brigades, which were retiring to the rear in confusion from the leaden storm.
