HEADQUARTERS SECOND ARMY CORPS, September 17, 1864.

Brigadier General S. WILLIAMS,
Assistant Adjutant-General, Army of the Potomac:

GENERAL: I consider if of the highest importance that as many as possible of the officers of the Second Corps now absent who are able to perform duty in the field be returned at once. As an example showing deficiency of officers of the Second Corps, the First Division, comprising twenty-six regiments or battalion, has only 140 officers present, including field, staff, and line. The Second Corps cannot be relied upon for great service without its officers, the best of whom, with few exceptions, are absent. With good officers to have commanded the men I could have won a decided victory at Reams' Station, aside from other considerations. The failure to perform all that has been demanded of the troops of this command lately has been owing to the great deficiency in this respect. If the Second Corps, after its great losses, is to be relied upon as a power this fall it can only fulfill expectations by giving it its best officers. A very large proportion of the additions being made to the command consists of new men, who require instructions, discipline, and example.

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

WINF'D S. HANCOCK,

Major-General of Volunteers.
