When the term of service of the Twenty-fifth had expired, Colonel W. H. Gibson, commanding the Brigade to which the Regiment was attached, addressed the men, through an order, in this highly complimentary manner:

"Soldiers of the Twenty-fifth Illinois Volunteers:  As your term for three years' service has expired, and you are about to proceed to your State to be mustered out, it is fitting and proper that the Colonel commanding should express to each and all his earnest thanks for the cheerful manhood with which, during the present campaign, you have submitted to every hardship, overcome every difficulty, and for the magnificent heroism with which you have met and vanquished the foe.  Your deportment in camp has been worthy true soldiers, while your conduct in battle has excited the admiration of your companions in arms.  Patriotic thousands and a noble State will give you a reception worthy of your sacrifice and your valor. You have done your duty.  The men who rallied under the starry emblem of our nationality at Pea Ridge, Corinth, Chaplin Hills, Stone River, Chickamauga, Mission Ridge, Noonday Creek, Pinetop Mountain, Kenesaw Mountain, Chattahoochie, Peach tree Creek and Atlanta, having made history for all time and coming generations to admire, your services will ever be gratefully appreciated.  Officers and soldiers, farewell!  May God guarantee to each health, happiness and usefulness in coming life and may our country soon emerge from the gloom of blood that now surrounds it, and again enter upon a career of progress, peace and prosperity."
