OSWEGO, N. Y., ---- 1862. GENTLEMEN: A very beautiful sabre, your present to myself, has been received. I shall wear it with pride, and will never draw it but in an honorable cause. The very kind letter accompanying the sabre has caused emotions of the deepest nature. The assurance it gives of the confidence you feel in myself, and your approval of my course when in command of Banks' Cavalry, is particularly gratifying. You, actors with myself in those stirring scenes, are competent judges as to the propriety of my course, when it unfortunately did not meet with the approval of my superior; and your testimony, so handsomely expressed, after time has allowed opportunity for reflection, more than compensates for the mortification of that moment. I have watched with pride the movements of your regiments since my separation from you. When a telegram has announced that "in a cavalry fight _the edge of the sabre_ was successfully used, and the enemy routed," the further announcement that the First Vermont and Fifth New York were engaged, was unnecessary. Accept my kindest wishes for your future success. Sharp sabres and a trust in Providence will enable you to secure it in the field. Your obedient servant, JOHN P. HATCH, _Brigadier-General_. _August 5._--The Harris Light was again sent out on a reconnoissance to the Central Railroad, which we struck on the sixth, about ten o'clock A. M., at Frederick's Hall. The depot, which contained large supplies of commissary and quartermaster stores, was burned. The telegraph office was also destroyed, with considerable length of wire, while the railroad track was torn and otherwise injured, principally by the fires we built upon it. In a factory near the station were found huge quantities of tobacco. The men took as much as the jaded condition of their horses would permit, and the remainder was wrapped in flames. All this was accomplished without loss on our side. These daring and successful raids made Kilpatrick very conspicuous before the army and country. He was complimented by the general commanding both in orders and by telegraph, and his name became a synonym of courage and success. This gave wonderful enthusiasm to his men, and their devotion to him was unbounded. Wherever he led us we gladly went, feeling that however formidable the force or dangerous the position we assailed, either by main force we could overcome, or by stratagem or celerity we could escape. This gave our young hero a double power.
