Captain B. F. Fisher, acting signal officer, in immediate charge of the party with the Army of the Potomac, and under whose personal supervision many of the stations reported were established, is entitled to mention for the zeal which has characterized his conduct throughout the campaign, and the courage and ability with which he discharged his duties at the battles of South Mountain and Antietam.

There are laid before the commanding general in this list the names of officers who have served in the presence of the enemy now for more than a year, and whose labors have elicited the official thanks of generals and their commanders. There is hardly one whose name has not been more than once officially mentioned for gallant or faithful service upon the Peninsula, in the Valley of the Shenandoah, or on the Rappahannock. There is yet no definite mode by which to give them substantial reward or promotion.

I am, general, very respectfully, your obedient servant,

ALBERT J. MYER,

Signal Officer, and Major, U. S. Army.

Brigadier General S. WILLIAMS,

Assistant Adjutant-General, Army of the Potomac
