first command?"

"That you dismount. The Sergeant must ride your horse, as he is the
more fit of the two."

Greatly to my surprise and relief she placed her gauntleted hand in
mine, and, without so much as a word of protest, permitted me to swing
her lightly from the saddle to the ground.

"Craig," I called, "come here"; and turning to her, added quietly,
"Kindly draw up your cape for a moment."

I noticed her hands fasten the clasps, which had become loosened, and
that she turned partially so as to look backward up the road as the
Sergeant drew near.

"You know your work," I said to him briefly. "And now the sooner you
are at it the better. Ride this horse and lead your own. As soon as you
deliver Lee's message at headquarters, hunt up the cavalry brigade
commander and report to him my position. Get a detail, insist upon one,
and be back here by to-morrow without fail. That is all."

He saluted, wheeled about, swung lightly into saddle, and rode off on a
rapid trot, grasping, as he passed down the hill, the rein of his own
mount, and leading it, lagging, behind him, until the night swallowed
the figures, and even the sound of the hoof-beats could be no longer
heard. We were alone.
