I am surrounded by soldiers and a little farther off by the citizens of this good City of Frederick. Nevertheless I can only say, as I did five minutes ago, it is not proper for me to make speeches in my present position. I return thanks to our soldiers for the good services they have rendered, the energy they have shown, the hardships they have endured, and the blood they have shed for this Union of ours; and I also return thanks, not only to the soldiers, but to the good citizens of Frederick, and to the good men, women, and children in this land of ours, for their devotion to this glorious cause; and I say this with no malice in my heart towards those who have done otherwise. May our children and children's children, for a thousand generations, continue to enjoy the benefits conferred upon us by a united country, and have cause yet to rejoice under these glorious institutions, bequeathed to us by Washington and his compeers. Now, my friends, soldiers and citizens, I can only say once more-farewell.
