But Meade did not attempt to leave his intrenchments and the Confederate army slowly and defiantly moved toward the South. The situation was perilous—desperately perilous for Lee. His troops were in no condition to fight after battling for three days, their ammunition was almost exhausted, their food supply was low and they were retreating through a hostile country with a victorious army behind them and a broad river in their path. But not a man in the gray ranks detected even a shadow of anxiety on his commander's face, and when the Potomac was reached and it was discovered that the river was impassable owing to an unexpected flood, the army faced about and awaited attack with sublime confidence in the powers of its chief.
Meanwhile Meade, who had been cautiously following his adversary, began to receive telegrams and dispatches urging him to throw himself upon the Confederates before they could recross the Potomac and thus end the war. But this, in the opinion of the Union commander, was easier said than done, and he continued to advance with the utmost deliberation while Lee, momentarily expecting attack, ferried his sick and wounded across the river and prepared for a desperate resistance. Absolute ruin now stared him in the face, for no reënforcements of any kind could reach him and a severe engagement would soon place him completely at his opponent's mercy. Nevertheless, he presented a front so menacing and unafraid that when Meade called his officers to a council of war all but two voted against risking an attack.
In the meantime the river began to fall, and without the loss of a moment Lee commenced building a bridge across which his troops started to safety on the night of July 13th, ten days after the battle. Even then the situation was perilous in the extreme, for had Meade discovered the movement in time he could undoubtedly have destroyed a large part of the retreating forces, but when he appeared on the scene practically the whole army was on the other side of the river and only a few stragglers fell into his hands.
Great as Lee's success had been he never appeared to better advantage than during this masterly retreat, when, surrounded by difficulties and confronted by overwhelming numbers, he held his army together and led it to safety. Through the dust of defeat he loomed up greater as a man and greater as a soldier than at any other moment of his career.
Even the decisive victories at Gettysburg and Vicksburg failed to offset President Lincoln's bitter disappointment at Lee's miraculous escape, and had it not been for his success on the field of battle, Meade would undoubtedly have been removed from the chief command. As it was, however, he retained his position and for months he lay comparatively idle, watching his opponent who busied himself with filling the broken ranks of his army for a renewal of the struggle.
Meanwhile, the Confederate newspapers began a bitter criticism of Lee, charging that he had displayed bad judgment and worse generalship in attempting to invade the North. A man of different caliber would, doubtless, have answered these attacks by exposing some of the officers whose conduct was largely responsible for the failure of the campaign. Indeed, the facts would have justified him in dismissing more than one of his subordinates from the army in disgrace, and had he chosen to speak the word he might easily have ruined the reputation of at least one distinguished general.
But no such selfish or vindictive thought ever crossed Lee's mind. Keenly as he suffered from the abuse which was heaped upon him, he endured it without a murmur and, when at last he felt obliged to notice it, his reply took the form of a letter to the Confederate President requesting his permission to resign.
"The general remedy for the want of success in a military commander is his removal," he wrote a month after the battle of Gettysburg. "I do not know how far the expressions of discontent in the public journals extend in the army. My brother officers have been too kind to report it and, so far, the troops have been too generous to exhibit it. I, therefore, beg you to take measures to supply my place, because if I cannot accomplish what I myself desire, how can I fulfill the expectations of others? I must confess, too that my eyesight is not good and that I am so dull that in making use of the eyes of others I am frequently misled. Everything, therefore, points to the advantages to be derived from a new commander. A younger and abler man can readily be obtained—one that would accomplish more than I can perform and all that I have wished. I have no complaints to make of anyone but myself. I have received nothing but kindness from those above me and the most considerate attention from my comrades and companions in arms."
This generous, dignified statement, modest to the point of self-effacement, instantly hushed all discontent and, before it, even the newspaper editors stood abashed.
"Where am I to find the new commander who is to possess that greater ability which you believe to be required?" wrote Jefferson Davis in reply. "If Providence should kindly offer such a person I would not hesitate to avail myself of his services. But my sight is not sufficiently penetrating to discover such hidden merit, if it exists. To ask me to substitute you by someone more fit to command is to demand an impossibility."
