The Sword of Antietam: A Story of the Nation's Crisis
“ Dick stared at him in amazement. “Everything you say is true,” he said, “but how did you know it?” “It's my business to know. Knowledge is my sole pursuit in this great war, and a most engrossing and dangerous task I find it. Yet, I would not leave it. My name is Shepard, and I am a spy. You needn't shrink. I'm not ashamed of my occupation. Why should I be? I don't kill. I don't commit any violence. I'm a guide and educator. I and my kind are the eyes of an army. We show the generals where the enemy is, and we tell them his plans. An able and daring spy is worth more than many a general. ”
