Booth, accompanied by David C. Herold, a fellow-conspirator, finally made his way into Maryland, where eleven days after the assassination the two were discovered in a barn on Garrett's farm near Port Royal on the Rappahannock. The barn was surrounded by a squad of cavalrymen, who called upon the assassins to surrender. Herold gave himself up and was roundly cursed and abused by Booth, who declared that he would never be taken alive.
The cavalrymen then set fire to the barn and as the flames leaped up the figure of the assassin could be plainly seen, although the wall of fire prevented him from seeing the soldiers. Colonel Conger saw him standing upright upon a crutch with a carbine in his hands.
When the fire first blazed up Booth crept on his hands and knees to the spot, evidently for the purpose of shooting the man who had applied the torch, but the blaze prevented him from seeing anyone. Then it seemed as if he were preparing to extinguish the flames, but seeing the impossibility of this he started toward the door with his carbine held ready for action.
His eyes shone with the light of fever, but he was pale as death and his general appearance was haggard and unkempt. He had shaved off his mustache and his hair was closely cropped. Both he and Herold wore the uniforms of Confederate soldiers.
