<P> In 1869 the Society of the Army of the Potomac was formed as a veterans association . It had its last reunion in 1929 . </P> <P> Because of its proximity to the large cities of the North, such as Washington, D.C., Philadelphia, and New York City, the Army of the Potomac received more contemporary media coverage than the other Union field armies . Such coverage produced fame for a number of this army's units . Individual brigades, such as the Irish Brigade, the Philadelphia Brigade, the First New Jersey Brigade, the Vermont Brigade, and the Iron Brigade, all became well known to the general public, both during the Civil War and afterward . </P> <P> The army originally consisted of fourteen divisions commanded by Edwin Sumner, William B. Franklin, Louis Blenker, Nathaniel Banks, Frederick W. Lander, Silas Casey, Irvin McDowell, Fitz - John Porter, Samuel Heintzelman, Erasmus Keyes, William F. Smith, Charles P. Stone (replaced by John Sedgwick in February 1862), and George McCall . Because this arrangement would be too hard to control in battle, President Lincoln issued an order on March 13, 1862, dividing the army into six corps headed by Sumner, Banks (despite being in the Shenandoah Valley and not part of the main army), McDowell, Heintzelman, and Keyes, the highest - ranking officers . McClellan was not happy with this, as he had intended to wait until the army had been tested in battle before judging which generals were suitable for corps command . </P> <P> After the Battle of Williamsburg on May 5, McClellan requested and obtained permission to create two additions corps; these became the V Corps, headed by Brig. Gen Fitz - John Porter, and the VI Corps, headed by Brig. Gen William B. Franklin, both personal favorites of his . After the Battle of Kernstown in the Valley on March 23, the administration became paranoid about "Stonewall" Jackson's activities there and the potential danger they posed to Washington D.C., and to McClellan's displeasure, detached Blenker's division from the II Corps and sent it to West Virginia to serve under John C. Fremont's command . McDowell's corps was detached as well and stationed in the Rappahannock area . </P>
