..."After sending my note this morning I received from the express office a bag of socks. You will have to send down your offerings as soon as you can, and bring your work to a close, for I think General Grant will move against us soon—within a week if nothing prevents—and no man can tell what will be the result; but trusting to a merciful God, who does not always give the battle to the strong, I pray we may not be overwhelmed. I shall, however, endeavor to do my duty and fight to the last. Should it be necessary to abandon our position to prevent being surrounded, what will you do? You must consider the question and make up your mind. It is a fearful condition and we must rely for guidance and protection upon a kind Providence...."

Shortly after this letter was written Lee made a desperate effort to force his adversary to loosen his grip but though the exhausted and starved troops attacked with splendid courage, they could not pierce the solid walls of infantry and fell back with heavy losses. Then Sheridan, who had been steadily closing in from the Shenandoah, swung 10,000 sabres into position and the fate of Petersburg was practically sealed. But, face to face with this calamity, Lee calmly wrote his wife:

"I have received your note with a bag of socks. I return the bag and receipt. I have put in the bag General Scott's autobiography which I thought you might like to read. The General, of course, stands out prominently and does not hide his light under a bushel, but he appears the bold, sagacious, truthful man that he is. I enclose a note from little Agnes. I shall be very glad to see her to-morrow but cannot recommend pleasure trips now...."

At every point Grant was tightening his hold upon the imprisoned garrison and difficulties were crowding fast upon their commander, but he exhibited neither excitement nor alarm. Bending all his energies upon preparations for a retreat, he carefully considered the best plan for moving his troops and supplying their needs on the march, quietly giving his orders to meet emergencies, but allowing no one to see even a shadow of despair on his face. Concerning the gravity of the situation he neither deceived himself nor attempted to deceive others who were entitled to know it, and with absolute accuracy he prophesied the movements of his adversary long before they were made.

..."You may expect Sheridan to move up the Valley," he wrote the Confederate Secretary of War.... "Grant, I think, is now preparing to draw out by his left with the intent of enveloping me. He may wait till his other columns approach nearer, or he may be preparing to anticipate my withdrawal. I cannot tell yet.... Everything of value should be removed from Richmond. It is of the first importance to save all the powder. The cavalry and artillery of the army are still scattered for want of provender and our supply and ammunition trains, which ought to be with the army in case of a sudden movement, are absent collecting provisions and forage. You will see to what straits we are reduced; but I trust to work out."

At last, on March 29th, 1865, Grant pushed forward 50,000 cavalry and infantry to execute the very move which Lee had outlined and for which he was as thoroughly prepared as it was possible to be with the men he had on hand. But to check this advance which threatened to surround his army and cut off his retreat, he had to withdraw the troops guarding the defenses of Petersburg, abandoning some of the intrenchments altogether and leaving nothing much more formidable than a skirmish line anywhere along his front. Even then he could not stop the onrush of the Union troops, which, under Sheridan, circled his right on April 1st and drove back his men in the fierce engagement known as the battle of Five Forks. With the news of this success Grant promptly ordered an assault against the intrenchments and his troops tore through the almost defenseless lines in several places, encountering little or no resistance.

Petersburg was not yet taken, but Lee immediately saw that to protect it further would be to sacrifice his entire army. He, therefore, sent a dispatch to Richmond, advising the immediate evacuation of the city. "I see no prospect of doing more than hold our position here till night. I am not certain that I can do that," he wrote. But he did hold on till the Confederate authorities had made their escape, and then on the night of April 2nd he abandoned the capital which he had successfully defended for four years and started on a hazardous retreat.

The one chance of saving his army lay in reaching the mountains to the west, before Grant could bar the road, but his men were in no condition for swift marching and the provision train which he had ordered to meet him at Amelia Court House failed to put in an appearance, necessitating a halt. Every moment was precious and the delay was exasperating, but he did his best to provide some sort of food for his famished men and again sent them on their way.

By this time, however, the Union troops were hot upon their trail and soon their rear-guard was fighting desperately to hold the pursuit in check. Now and again they shook themselves free, but the moment they paused for food or rest they were overtaken and the running fight went on. Then, little by little, the pursuing columns began to creep past the crumbling rear-guard; cavalry pounced on the foragers searching the countryside for food and captured the lumbering provision-wagons and the railroad supply trains which had been ordered to meet the fleeting army, while hundreds upon hundreds of starving men dropped from the ranks as they neared the bypaths leading to their homes.

Still some thousands held together, many begging piteously for food at every house they passed and growing weaker with each step, but turning again and again with a burst of their old spirit to beat back the advance-guard of the forces that were slowly enfolding them.
