“Quite certain, general,” said Mr. Nighthawk, serenely.

“You were in the camps?”

“In all, I believe, and at army head-quarters.”

“You overheard your intelligence?”

“No, I captured it, general.”

“How?”

“A courier was sent in haste—I saw the commander-in-chief speaking to him. I followed—came up with him in a hollow of the woods—and was compelled to blow his brains out, as he would not surrender. I then searched his body, and found what I wanted. There it is general.”

And Nighthawk drew forth a paper.

“What is it?” exclaimed Stuart.

“Grant’s confidential order to his corps commanders, general, directing the movements of his army.”
