But things did not turn out as he expected. The inhabitants of Maryland did not rally to him, McClellan was soon after him with a great army, and on September 17, overtook him at Antietam, and fought a desperate battle; from which Lee, overwhelmed by an army half again as large as his own, was forced to withdraw defeated, though in good order, and recross the Potomac into Virginia. Three months later, he got his revenge in full measure at Fredericksburg, routing Burnside with fearful loss, and early in May of the following year scored heavily again by defeating Hooker at Chancellorsville. The last victory was a dearly-bought one, for it cost the life of that most famous of all American cavalry leaders, "Stonewall" Jackson, of whom we shall speak hereafter. That was the culmination of Lee's career, for two months after Chancellorsville, having started on another great invasion of the North, on the fourth day of July, 1863, he was forced to retire from the fierce battle of Gettysburg with his army seriously crippled and with all hope of invading the North at an end. He was on the defensive, after that, with Grant's great army gradually closing in upon him and drawing nearer and nearer to Richmond. That he was able to prolong this struggle for nearly two years, especially considering the exhausted state of the South, was remarkable to the last degree, eloquent testimony to the high order of his leadership. Toward the last, his men were in rags and practically starving, but there was no murmuring so long as their beloved "Marse Robert" was with them. On the ninth day of April, 1865, six days after the fall of Richmond, Lee found himself surrounded at Appomattox Courthouse by a vastly superior force under General Grant. To have fought would have meant a useless waste of human life. Lee chose the braver and harder course, and surrendered. He knew that there could be but one end to the struggle, and he was brave enough to admit defeat. On that occasion, Grant rose to the full stature of a hero. He treated his conquered foe with every courtesy; granted terms whose liberality was afterwards sharply criticised by the clique in control of Congress, but which Grant insisted should be carried out to the letter; sent the rations of his own army to the starving Confederates, and permitted them to retain their horses in order that they might get home, and have some means of earning a livelihood.
