GENERAL JOHN B. GORDON'S last work was the publishing of his "Reminiscences of the Civil War." This volume, written in his vigorous style and broad, patriotic spirit, has been most favorably received and read all over the country. Since his death this memorial edition is brought out; and it is appropriate that an additional introduction should accompany it, somewhat in the shape of a biographical sketch. General John Brown Gordon was an all-round great man--a valiant and distinguished soldier, an eminent statesman, a great orator, an author of merit, and a public-spirited and useful citizen. He was born in Upson County, Georgia, February 6, 1832. His father was the Rev. Zachary Herndon Gordon. The family was of Scotch extraction, and its members fought in the Revolutionary War. He received his education at the university of his native State, and by profession was a lawyer. At the breaking out of the war, in 1861, he enlisted as a private soldier, and was elected captain of his company. His career was perhaps as brilliant as that of any officer in the Confederate army. In rapid succession he filled every grade--that of Major, Lieutenant-Colonel, Colonel, Brigadier-General, Major-General, and, near the end, was assigned to duty as Lieutenant-General (by authority of the Secretary of War), and while he never received the commission in regular form, he commanded, at the surrender at Appomattox, one half of the Army of Northern Virginia, under Robert E. Lee.
