I feel authorized to say by the evacuation the plan of campaign of the enemy was utterly foiled-his delay of seven weeks and was expenditures were of little value, and he has reached Corinth to find it a barren locality, which he must abandon as wholly worthless for his purposes.

I have the honor to be, respectfully, your obedient servant,

G. T. BEAUREGARD,

General, Commanding.

General S. COOPER,

Adjutant and Inspector General C. S. Army, Richmond, Va.

P. S.-My effective force on the morning of the evacuation (May 30) did not exceed 47,000 men, of all arms. That of the enemy, obtained from the best sources of information, could not have been less than 90,000 men, of all arms.
