"My duty to my country, which has been intrusted to me by God, compels me to-day, when the enemy has penetrated into the interior of the empire, to take supreme command of the active forces, and to share with the army the fatigue of war, and to safeguard with it Russian soil from attempts of the enemy. The ways of Providence are inscrutable, but my duty and my desire determine me in my resolution for the good of the state. "The invasion of the enemy on the western front, which necessitates the greatest possible concentration of civil and military authorities as well as the unification of command in the field, has turned our attention from the southern front. At this moment I recognize the necessity of your assistance and counsels on the southern front, and I appoint you viceroy of the Caucasus and commander in chief of the valiant Caucasian army. "I express to Your Imperial Highness my profound gratitude, and that of the country for your labors during the war. "NICHOLAS." The grand duke addressed his former armies before departing to his new sphere of activity as follows: "Valiant Army and Fleet: To-day your august supreme chief, His Majesty the Emperor, places himself at your head; I bow before your heroism of more than a year, and express to you my cordial, warm, and sincere appreciation. "I believe steadfastly that because the emperor himself, to whom you have taken your oath, conducts you, you will display achievements hitherto unknown. I believe that God from this day will accord to His elect His all-powerful aid, and will bring to him victory. "NICHOLAS, "General Aide de Camp."
