After that the "unicorn" and the fine old negro who wore it were both amply respected. When everything in sight had been eaten, the prisoners were ordered to fall in line. Their guards stood in front of the little column, beside it, behind it. "Forward, march!" They marched southward for a few miles, tramped through the swarming, somber streets of Richmond, and reached Libby Prison. Its doors closed behind them with a clang. Captivity in the open had been hard enough to bear. This new kind of captivity, within doors, with barred windows, was to be harder yet. Tom was to spend six weary months in Libby Prison. * * * * * It was while he was there that Abraham Lincoln made his wonderful Gettysburg speech. The battlefield of Gettysburg was made sacred by the men who died there for Freedom's sake and also by the men who died there for the sake of what they honestly thought were the rights of the Slave States. Congress made the battlefield a Soldiers' Cemetery. It was to be dedicated to its great memories on November 19, 1863. The morning before a special train left Washington for Gettysburg. It carried President Lincoln, Secretary of State Seward, two other members of the Cabinet, the two private secretaries, Nicolay and Hay, the distinguished Pennsylvanian, Wayne MacVeagh, later U. S. Attorney-General and later still our Minister to Italy, and others of lesser note. Among those latter was the Hon. Thomas Strong, who had been made one of the party by Lincoln's kind thoughtfulness. It was he who afterwards told his son the story of Lincoln's Gettysburg speech, scarcely regarded at the moment, but long since recognized as one of the masterpieces of English literature. The little town of Gettysburg was in a ferment that November night, when the President's train arrived. It was full of people and bands and whisky. Crowds strolled through the streets, serenading statesmen and calling for speeches with an American crowd's insatiable appetite for talky-talk. "MacVeagh," says Hay, "made a most beautiful and touching speech of five minutes," but another Pennsylvanian made a most disgusting and drunken speech of many minutes. Lincoln and most of his party of course had no share in all this brawling merriment. He and Seward had talked briefly to shouting thousands early in the evening.
