Major-General of Volunteers.

HEADQUARTERS MIDDLE DEPARTMENT,
Baltimore, Md., July 15, 1864.

Commodore DORNIN:

DEAR SIR: In reply to your favor of this date, I have the honor to say that the president of the Western Maryland Railroad Company sends information that large bodies of rebel cavalry this morning crossed his road near Finksburg a little village below Westminster, going northward and eastward. I infer from this that the enemy has design against the roads. In case Baltimore should be also in their contemplation, prudence suggests that your 400 men, just arrived, should be retained a little while longer. I have the honor, therefore, to request that your order them to be reported to Brigadier-General Lockwood, who will distribute them in the several works of the city. Also that the gun-boats you mention be furnished with supplies, and allowed to remain at the [points] they at present occupy.

Very respectfully, your friend and servant,

LEW. WALLACE,

Major-General, Commanding Middle Department.

P. S. -The departure of Major-General Ord with the greater part of the effective troops makes the necessity upon which the requests above are predicated.

Very respectfully,
