Just at this moment I again received a warning from my supporters, and hastily jumping to the ground, we hid ourselves until the pedestrians had passed out of sight and hearing. When I resumed my station the Captain and Mrs. Greenhow were seated at a table in the rear part of the room, and their conversation was carried on in such low tones that, in consequence of the storm that was still raging, I could not catch but fragmentary sentences. At last, however, accustoming myself to the noise, I heard enough to convince me that this trusted officer was then and there engaged in betraying his country, and furnishing to his treasonably-inclined companion such information regarding the disposition of our troops as he possessed.
Presently, he took from an inner pocket of his coat a map which, as he held it up before the light, I imagined that I could identify as a plan of the fortifications in and around Washington, and which also designated a contemplated plan of attack.
My blood boiled with indignation as I witnessed this scene, and I longed to rush into the room and strangle the miscreant where he sat, but I dared not utter a word, and was compelled to stand by, with the rain pouring down upon me, and silently witness this traitorous proceeding.
After watching their movements for some time, during which they would frequently refer to the map before them, as though pointing out particular points or positions, I was again compelled to hide myself under the shelter of the convenient stoop, and when I resumed my position the room was empty. The delectable couple had disappeared. I waited impatiently for more than an hour, taking occasional glimpses into the room and watching for their re-appearance. At the end of that time they re-entered the parlor arm in arm, and again took their seats.
Again came the warning voice, and again I hastily descended, and as the retreating figures disappeared in the distance, I could hear the front door open and the step of the traitor Captain above me.
With a whispered good-night, and something that sounded very much like a kiss, he descended the steps, and then, without paying any attention to the fact that I was without shoes, I started in pursuit of him, and through the blinding mist and pelting storms kept him in view as he rapidly walked away. It was then about half-past twelve o'clock, and the storm evinced no sign of a discontinuance.
I was not sufficiently acquainted with the city at that time to tell in what direction he was going, but I determined to ascertain his destination before I left him. I was compelled to keep pretty close to him, owing to the darkness of the night, and several times I was afraid that he would hear the footsteps of the man who accompanied me—mine I was confident would not be detected as, in my drenched stockings, I crept along as stealthily as a cat. Twice, I imagined that he turned around as though suspecting he was followed, but as he did not stop I reassured myself and plodded on. I could not, however, disabuse my mind of the fear that I had been seen, I could not relax my vigilance, and I resolved to take my chances of discovery. I knew who my man was, at all events, and now I must ascertain where he was going.
As we reached the corner of Pennsylvania avenue and Fifteenth street I imagined that I saw a revolver glistening in his hand, but it was too dark for me to determine that fact with any degree of certainty. At this point he passed a guard on duty, and quickly passed into a building immediately in advance of me.
This movement was so unexpected, that I had no time to turn back, and I was so close to him that it would have been very unwise to have done so, but I was more surprised when, as I reached the building into which the Captain had disappeared, I was suddenly confronted by four armed soldiers, who rushed suddenly out upon me, with fixed bayonets pointed at my breast.
"Halt, or I fire!" called out the officer of the guard.
