union generals in charge of the army of the potomac
Army of the Potomac 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.
Battle of Fredericksburg The Battle of Fredericksburg was fought December 11â€“15, 1862, in and around Fredericksburg, Virginia, between General Robert E. Lee's Confederate Army of Northern Virginia and the Union Army of the Potomac, commanded by Major General Ambrose Burnside, as part of the American Civil War. The Union Army's futile frontal attacks on December 13 against entrenched Confederate defenders on the heights behind the city are remembered as one of the most one-sided battles of the war, with Union casualties more than three times as heavy as those suffered by the Confederates. A visitor to the battlefield described the battle to U.S. President Abraham Lincoln as a "butchery."[14]
