July 1-3, 1863
Gen. Robert E. Lee concentrated his full strength against Maj. Gen. George G. Meade's Army of the Potomac at the crossroads county seat of Gettysburg. On July 1, Confederate forces converged on the town from west and north, driving Union defenders back through the streets to Cemetery Hill. During the night, reinforcements arrived for both sides. On July 2, Lee attempted to envelop the Federals, first striking the Union left flank at the Peach Orchard, Wheatfield, Devil's Den, and the Round Tops with Longstreet's and Hill's divisions, and then attacking the Union right at Culp's and East Cemetery Hills with Ewell's divisions. By evening, the Federals retained Little Round Top and had repulsed most of Ewell's men. During the morning of July 3, the Confederate infantry were driven from their last toe-hold on Culp's Hill. In the afternoon, after a preliminary artillery bombardment, Lee attacked the Union center on Cemetery Ridge. The Pickett-Pettigrew assault (more popularly, Pickett's Charge) momentarily pierced the Union line but was driven back with severe casualties. Stuart's cavalry attempted to gain the Union rear but was repulsed. On July 4, Lee began withdrawing his army toward Williamsport on the Potomac River. His train of wounded stretched more than fourteen miles.

To George G. Meade
July 14, 1863
Major General Meade:
I have just seen your despatch to Gen. Halleck, asking to be relieved of your command, because of a supposed censure of mine. I am very - very - grateful to you for the magnificent success you gave the cause of the country at Gettysburg; and I am sorry now to be the author of the slightest pain to you. But I was in such deep distress myself that I could not restrain some expression of it. I had been oppressed nearly ever since the battles of Gettysburg, by what appeared to be evidence that yourself, and Gen. Couch, and Gen. Smith, were not seeking a collision with the enemy, but were trying to get him across the river without another battle. What these evidences were, if you please, I hope to tell you at some time, when we shall both feel better. The case, summarily stated is this. You fought and beat the enemy at Gettysburg; and, of course, to say the least, his loss was as great as yours. He retreated; and you did not, as it seemed to me, pressingly pursue him; but a flood in the river detained him, till, by slow degress, you were again upon him. You had at least twenty thousand veteran troops directly with you, and as many more raw ones within supporting distance, all in addition to those who fought with you at Gettysburg; while it was not possible that he had received a single recruit; and yet you stood and let the flood run down, bridges be built, and the enemy move away at his leisure, without attacking him. And Couch and Smith! The latter left Carlisle in time, upon ordinary calculation, to have aided you in the last battle at Gettysburg; but he did not arrive. At the end of more than ten days, I believe twelve, under constant urging, he reached Hagerstown from Carlisle, which is not an inch over fiftyfive miles, if so much. And Couch's movement was very little different.
Again, my dear general, I do not believe you appreciate that magnitude of the misfortune involved in Lee's escape. He was within your easy grasp, and to have closed upon him would, in connection with our other late successes, have ended the war. As it is, the war will be prolonged indefinitely. If you could not safely attack Lee last Monday, how can oyu possibly do so South of the river, when you can take with you very few more than two thirds of the force you then had in hand? It would be unreasonable to expect, and I do not expect you can now effect much. Your golden opportunity is gone, and I am distressed immeasureably because of it.
I beg you will not consider this a prossecution, or persecution of yourself. As you had learned that I was dissatisfied, I have thought it best to kindly tell you why.
Lincoln never sent the letter.
