The army was divided, for the purposes of this march, into two great wings. The right, keeping its army name, was commanded by General Howard, and consisted of the Fifteenth Corps, under Osterhaus, and the Seventeenth Corps, under Blair. The left, called Army of Georgia, was commanded by General Slocum, and consisted of the Fourteenth Corps, under J. C. Davis, and the Twentieth Corps, under A. S. Williams. In all there were about 60,000 infantry and 60 cannon. In addition, there was a cavalry division of 5,500 men, under General Kilpatrick. General Howard was now 34 years old; a native of Maine, and a graduate of West Point in the class of 1854. He had served in Florida against the Indians, and as an instructor at West Point. He had joined the army again as Colonel of the first three years' regiment that came from Maine; had commanded a brigade at Bull Run and served with the Army of the Potomac until the battle of Fair Oaks, where he had lost his right arm while leading a gallant charge. Two months later, he had returned to active service in time to be at the second battle of Bull Run, where he commanded the rear guard on the retreat. He had rendered distinguished service at Antietam and Fredericksburg, and also at Chancellorsville. He had been one of the chief actors at Gettysburg, being responsible for the selection of the invincible position at Cemetery Ridge occupied by the Union Army. His gallantry at Missionary Ridge has already been recorded in these pages, and he had also marched with Sherman to the relief of Burnside at Knoxville. His Christian character and his intellectual attainments made him as acceptable as a man as he was as a brave and skilful General. General Slocum, a native of New York State, had been graduated at West Point two years before Howard. After some military service he had become a practicing lawyer and active in the politics of his State. At the outbreak of the war he had returned to the army as Colonel of one of the first three years' regiments sent from New York. He had served with honor at Bull Run and with the Army of the Potomac on the Rappahannock and at Yorktown and all through the Peninsula campaign from West Point, Va., to Malvern Hill. He had won great distinction at South Mountain and Antietam, at Fredericksburg, Chancellorsville and Gettysburg. He and Howard were trusted lieutenants of Sherman in the great campaign that was now to be undertaken. Kilpatrick came from New Jersey, and was only 26 years old. He had been graduated at West Point in 1861, just in time to rush to the front with Duryeas's Zouaves, and received a slight wound at Big Bethel. Then he received a cavalry command and pursued a brilliant career with the Army of the Potomac, until he was sent to assist Sherman in Georgia.
