Lee had invaded the North, delivered battle on the territory of the enemy, suffered a repulse, retired, and was again occupying nearly the same ground which he had occupied before the advance. Moving backward and forward on the great chessboard of war, the two adversaries seemed to have gained or lost nothing. The one was not flushed with victory; the other was not prostrated by defeat. Each went into camp, ceased active operations, and prepared for the new conflict which was to take place before the end of the year. I shall record some incidents of that rapid and shifting campaign, beginning and ending in the month of October; then I pass on to the more important and exciting pages of my memoirs: the mighty struggle between Lee and Grant. To return for a moment to the cavalry. It held the front along the Rapidan and Robertson rivers, from Madison Court-House on the left, to Chancellorsville on the right. Stuart kept his lynx-eye on all the fords of the two rivers, having his head-quarters in the forks of the streams not far from their junction. I should like to speak of the charming hours spent at the hospitable mansion near which head-quarters had been established. The sun shone bright, at the house on the grassy hill, but not so bright as the eyes which gave us friendly welcome. Years have passed since that time--all things have changed--but neither time or the new scenes will banish from some hearts the memory of that beautiful face, and the music of that voice! We salute to-day as we saluted in the past--health and happiness attend the fair face and the kindly heart! I saw much of Mohun in those days, and became in course of time almost his intimate friend. He exhibited still a marked reserve on the subject of his past life: but I thought I could see that the ice was melting. Day by day he grew gayer--gradually his cynicism seemed leaving him. Who was this singular man, and what was his past history? I often asked myself these questions--he persisted in giving me no clue to the secret--but I felt a presentiment that some day I should “pluck out the heart of his mystery.” So much, in passing, for my relations with Mohun. We had begun to be friends, and the chance of war was going to throw us together often. I had caught one or two glimpses of a past full of “strange matters”--in the hours that were coming I was to have every mystery revealed. Meanwhile Lee was resting, but preparing for another blow. His army was in the highest spirits. The camps buzzed, and laughed, and were full of mirth. Gettysburg was forgotten, or if remembered, it only served to inflame the troops, and inspire them with a passionate desire to “try again.” In the blaze of a new victory, the old defeat would disappear. Such was the condition of things in the army of Northern Virginia in the first days of October, 1863. III. THE OPENING OF THE HUNT. It soon became obvious that Lee had resolved to strike a blow at his adversary.
