But Brant had been watching her varying expression, her kindling eye, her strange masculine grasp of military knowledge, her soldierly phraseology, all so new to her, that he scarcely heeded the feminine ending of her speech.  It seemed to him no longer the Diana of his youthful fancy, but some Pallas Athene, who now looked up at him from the pillow.  He had never before fully believed in her unselfish devotion to the cause until now, when it seemed to have almost unsexed her.  In his wildest comprehension of her he had never dreamed her a Joan of Arc, and yet hers was the face which might have confronted him, exalted and inspired, on the battlefield itself.  He recalled himself with an effort.

“I thank you for your would-be warning,” he said more gently, if not so tenderly, “and God knows I wish your flight had been successful.  But even your warning is unnecessary, for the supports had already come up; they had followed the second signal, and diverged to engage our division on the left, leaving me alone.  And their ruse of drawing our commander to assist me would not have been successful, as I had suspected it, and sent a message to him that I wanted no help.”

It was the truth; it was the sole purport of the note he had sent through Miss Faulkner.  He would not have disclosed his sacrifice; but so great was the strange domination of this woman still over him, that he felt compelled to assert his superiority.  She fixed her eyes upon him.

“And Miss Faulkner took your message?” she said slowly.  “Don’t deny it!  No one else could have passed through our lines; and you gave her a safe conduct through yours.  Yes, I might have known it.  And this was the creature they sent me for an ally and confidant!”

For an instant Brant felt the sting of this enforced contrast between the two women.  But he only said,—­

“You forget that I did not know you were the spy, nor do I believe that she suspected you were my wife.”

“Why should she?” she said almost fiercely.  “I am known among these people only by the name of Benham—–­my maiden name.  Yes!—­you can take me out, and shoot me under that name, without disgracing yours.  Nobody will know that the Southern spy was the wife of the Northern general!  You see, I have thought even of that!”

“And thinking of that,” said Brant slowly, “you have put yourself—­I will not say in my power, for you are in the power of any man in this camp who may know you, or even hear you speak.  Well, let us understand each other plainly.  I do not know how great a sacrifice your devotion to your cause demands of you; I do know what it seems to demand of me.  Hear me, then!  I will do my best to protect you, and get you safely away from here; but, failing that, I tell you plainly that I shall blow out your brains and my own together.”

She knew that he would do it.  Yet her eyes suddenly beamed with a new and awakening light; she put back her hair again, and half raised herself upon the pillow, to gaze at his dark, set face.
