General,—I enclose a copy of the order assigning
General Johnston to command, of which you have already been notified by telegram.
I did not need the assurance contained in your reply to my despatch, of your cheerful acquiescence and willing co-operation in a measure deemed necessary for the good of the service, knowing as I do that personal considerations have no place in your mind when the welfare of the country is concerned.
The situation of affairs in my judgment requires that we should put forth our best efforts, and I was desirous that we should not, in such an emergency, be without the assistance of the skill and ability of one of our most distinguished officers.
The reports that have reached me of the precarious condition of your health made me the more anxious lest the arduous and responsible duties that have devolved upon you should prove too great for your physical capacity, and I could not but feel apprehensive of the consequences of being deprived of your services at a critical moment.
I trust, however, that you will how be able, without injury to yourself, to afford
General Johnston the full benefit of your support.
I beg to return you my thanks for the gratification I derive from the knowledge that the course I have thought most judicious is not misunderstood or unappreciated by yourself.
Very respectfully, your obedient servant,
