You will cause the several commanders to direct their energies to the thorough preparation of their respective commands for efficent service in the campaign soon to open and apply your own efforts to the same end. There is no time to be lost. Although horses cannot yet be called in because of insufficient forage, there are many elements of equipments and organization to be attended to at once. It is essential to get each command ready for service, so that however early or unexpectedly the enemy may advance the horse artillery battalion may on short notice repair to operate with their proper divisions.
Very respectfully, your obedient servant,
W. N. PENDLETON,
Brigadier-General and Chief of Artillery.
