Early on the morning after these events the two men, captor and captive, sat in the tent of the former. A table was between them on which lay, among a number of letters, official and private, which the captain had written during the night, the incriminating papers found upon the spy. That gentleman had slept through the night in an adjoining tent, unguarded. Both, having breakfasted, were now smoking.

“Mr. Brune,” said Captain Hartroy, “you probably do not understand why I recognized you in your disguise, nor how I was aware of your name.”

“I have not sought to learn, Captain,” the prisoner said with quiet dignity.

“Nevertheless I should like you to know—if the story will not offend. You will perceive that my knowledge of you goes back to the autumn of 1861. At that time you were a private in an Ohio regiment—a brave and trusted soldier. To the surprise and grief of your officers and comrades you deserted and went over to the enemy. Soon afterward you were captured in a skirmish, recognized, tried by court-martial and sentenced to be shot. Awaiting the execution of the sentence you were confined, unfettered, in a freight car standing on a side track of a railway.”

“At Grafton, Virginia,” said Brune, pushing the ashes from his cigar with the little finger of the hand holding it, and without looking up.

“At Grafton, Virginia,” the captain repeated. “One dark and stormy night a soldier who had just returned from a long, fatiguing march was put on guard over you. He sat on a cracker box inside the car, near the door, his rifle loaded and the bayonet fixed. You sat in a corner and his orders were to kill you if you attempted to rise.”

“But if I asked to rise he might call the corporal of the guard.”

“Yes. As the long silent hours wore away the soldier yielded to the demands of nature: he himself incurred the death penalty by sleeping at his post of duty.”

“You did.”

“What! you recognize me? you have known me all along?”

The captain had risen and was walking the floor of his tent, visibly excited. His face was flushed, the grey eyes had lost the cold, pitiless look which they had shown when Brune had seen them over the pistol barrel; they had softened wonderfully.

“I knew you,” said the spy, with his customary tranquility, “the moment you faced me, demanding my surrender. In the circumstances it would have been hardly becoming in me to recall these matters. I am perhaps a traitor, certainly a spy; but I should not wish to seem a suppliant.”

The captain had paused in his walk and was facing his prisoner. There was a singular huskiness in his voice as he spoke again.

“Mr. Brune, whatever your conscience may permit you to be, you saved my life at what you must have believed the cost of your own. Until I saw you yesterday when halted by my sentinel I believed you dead—thought that you had suffered the fate which through my own crime you might easily have escaped. You had only to step from the car and leave me to take your place before the firing-squad. You had a divine compassion. You pitied my fatigue. You let me sleep, watched over me, and as the time drew near for the relief-guard to come and detect me in my crime, you gently waked me. Ah, Brune, Brune, that was well done—that was great—that—”

The captain’s voice failed him; the tears were running down his face and sparkled upon his beard and his breast. Resuming his seat at the table, he buried his face in his arms and sobbed. All else was silence.
