"But I have had no report of his arrest," cried the colonel. "How came you here, sir?"

"I wish to place myself under your protection," said Penn. "You received a substitute in my place, and ordered me to be set at liberty. But your commands have been disregarded; I have been hunted for two days; and men, calling themselves confederate soldiers, are still pursuing me. Under these circumstances I have thought it best to appeal to you, relying upon your honor as a gentleman and an officer."

"But how came you here? Who brought in this fellow?"

Nobody could answer that question, although the leader of the party that had brought him in was at the very moment on the spot, waiting to make his report of Stackridge's arrest.

As soon, therefore, as Penn could gain a hearing, he continued.

"I came in, sir, with a crowd of soldiers and prisoners, none of whom recognized me. The sentinels no doubt supposed I was arrested, and so let me pass."

"Well, sir, you have done a bold thing, and perhaps the best thing for you. Since you have voluntarily delivered yourself up, I shall feel bound to protect you. But I have only one of two alternatives to offer you—the same I offer to each of these worthy gentlemen here, giving them their choice. Take the oath of allegiance to the confederate government, and volunteer; that is one condition."

"I am a northern man," replied Penn, "and owe allegiance to the United States; so that condition it is impossible for me to accept."

"Very well; I'll give you time to think of it. In the mean while, my only means of affording the protection you demand will be to retain you a prisoner. Guard, take this man below."

Not another word was said; and, indeed, Penn had already gained more than he hoped for, with the eyes of Lieutenant Ropes glaring on him so murderously. He was conducted to a stairway that led to the cellar, and ordered to descend. He obeyed, marching down between two soldiers on guard at the door, and two more at the foot of the stairs.
