On the staff I had been thrown into intimate relations to Colonel William M. Wherry, senior aide-de-camp, and Major J. A. Campbell, adjutant-general. These officers continued to the end of the war in these positions, which they filled with great credit and usefulness. Major Campbell was admirably fitted for the supervision of the records and the correspondence of the army, and for reducing to the form of clear and succinct orders the directions of the general. He was accurate, systematic, and untiring; always at his post, whether it were at his desk in camp, or by the side of his chief in the field. Of slight, almost frail body, with an intellectual face, he looked unequal to rough field work, but showed a stamina in fact which many a more robust man envied. Colonel Wherry was the incessantly active personal representative of the general, intrusted with his oral orders, and making for him those examinations and investigations which are only satisfactory when the commander has learned to trust the eye and the cool judgment of his assistant as his own. Wherry had been with General Schofield from the first campaign in Missouri in 1861, and both were with Lyon when he fell at Wilson's Creek. He remained his confidential aide through the whole war, and for years afterward, being early appointed from Missouri to the line of one of the new regiments of the regular army. Lithe, graceful, and genial, he was always welcome, when he came to a point where fighting was going on, to learn for the general the actual situation or to bring his orders. [Footnote: Wherry is now (1899) Brigadier-General of the United States Army, retired, after brilliant service in the campaign of Santiago, Cuba.]
