I have thought often since, however, (then other than the deliberate thought which every man in trying circumstances has experienced, and which centres upon one subject, being so severe a tension of all the faculties as to seem no thought at all, was impossible,) that it would be unwise, and perhaps a stumbling-block to future Union captives in the custody of that horrid host, to ascribe my unbroken rest under those dry, dusty bush-branches simply to the heavy darkness of the evening, excluding all other causes from participation in my affairs. It was unusually cloudy, the sky resting overhead like a hanging pall, and threatening rain with thunder every moment, as is almost always the case after a hotly contested engagement. The fight that morning had been a grand one, (quite a Horace Vernet picture,) and hence the clouds that night. But I must own that I give my Sergeant a place in my memory now with a feeling of gratitude, induced thereto by the strong supposition that he did not allow himself to see me as I glided under cover. I count much upon his heart, as shown in his little proffered narrative. The other guards on the line might readily have failed to notice me, the more so as I had a special attendant to see to my wants; and I should have been very sorry, indeed, had one of them disturbed my rest. But my Sergeant was not three body-lengths from me when I slipped away from his protection; and although he had his back turned, I am inclined to think that he had only fewer eyes than Argus. His general reputation, to be read in his bearing, pronounced him vigilant, and his every act betokened circumspection. Far be it from me, however, to bespatter his character by avowing him negligent in performing his duty in this case, whilst lauding him for his honest devotion to his masters. Perhaps it may have been a part of his care to see the squad "fall in," and he could not abandon that line of his duty to search for a stray officer, smooth-spoken and amiable, to whom he had just shown a kindness. The bustle and unnatural darkness of the moment could not inspire one who was not a demon with a demoniacal desire to set a screeching and rash body of troopers upon my track. The detachment of melancholy mutes was moving off when I tried my fate; and he could have had but little time to think ere the miserable men were in the distance. The farther my Sergeant journeyed, the more likely he was to keep quiet upon my subject.
